May 2008 Earthquake in China Could Be Followed by Another Significant Rupture

May 2008 Earthquake in China Could Be Followed by Another Significant Rupture

Researchers analyzing the May 2008 Wenchuan earthquake in China's Sichuan province have found that geological stress has significantly increased on three major fault systems in the region.

The magnitude 7.9 quake on May 12 has brought several nearby faults closer to failure and could trigger another major earthquake in the region.

Geophysicists used computer models to calculate the changes in stress along the Xianshuihe, Kunlun, and Min Jiang faults-strike-slip faults like the San Andreas-which lie about 150 to 450 kilometers (90 to 280 miles) from the Longmen Shan rupture that caused the devastating quake. The research team also examined seismic activity in the region over the past decade.

They found that the May 12 event has doubled the probabilities of future earthquakes on these fault lines. Specifically, they estimated the probability of another earthquake of magnitude 6 or greater in the region is 57 to 71 percent over the next decade. There is an 8 to 12 percent chance of a quake larger than magnitude 7 in the next decade and 23-31 percent in the next 30 years.

The research team was led by Shinji Toda of the Geological Survey of Japan, and includes Jian Lin of the Woods Hole Oceanographic Institution (WHOI), Mustapha Meghraoui of the Institute of Geophysics in Strasbourg (France), and Ross Stein of the U.S. Geological Survey (USGS). Their findings were published September 9 in the online edition of the journal Geophysical Research Letters.

"One great earthquake seems to make the next one more likely, not less," said Stein, who has been collaborating with Lin and Toda for nearly two decades. "We tend to think of earthquakes as relieving stress on a fault. That may be true for the one that ruptured, but not for the adjacent faults."

In 1999, a 7.4 magnitude earthquake in Izmit, Turkey, was followed four months later by an M7.1 event in nearby Duzce. The devastating December 2004 Sumatra earthquake (M9.2) and tsunami were followed by an M8.7 quake three months later.

"Because the Tibetan Plateau is one of the most seismically active regions in the world, we believe there is credible evidence for a new major quake in this region," said Lin, a senior scientist in WHOI's Department of Geology and Geophysics. "The research community cannot forecast the timing of earthquakes, and there are still significant uncertainties in our models. But the Turkey and Sumatra events indicate that one major earthquake can indeed promote another.

Researchers see it as a domino-like effect, where the movement of one piece of Earth's crust means that another piece must move up, down, or away. While the stress in the crust gets reduced in some locations, it is transferred to other faults nearby.

Large aftershocks that occurred on August 1 and 5 in the Sichuan region of China may fit with this predicted pattern.

"Earthquake prediction is a bit like the thundercloud and lightning," Toda explained. "We can forecast that lightning will come from a thundercloud, but we cannot predict the exact time and place where the lightning will hit. With earthquakes, we can roughly forecast the probability of activity over broad ranges of time, magnitude, and location, but we cannot determine the exact value for any of these."

On May 12, 2008, about 300 kilometers of the Longmen Shan fault zone ruptured in an earthquake that killed at least 69,000 people and left another 5 million homeless. It was the deadliest and strongest earthquake to hit China since the 1976 Tangshan earthquake, which killed at least 240,000.

As pieces of the Longman Shan fault slipped by as much as nine meters (28 feet) in the May quake, stress increased along the neighboring Xianshuihe, Kunlun, and Min Jiang faults, according to Toda and colleagues. All three faults have a history of large quakes, though portions of each have been quiet for most of the past century. All three faults were considered to be primed for an earthquake even before the recent events.

In addition to the broad prediction of earthquake triggering, the researchers have also forecasted the rate and distribution of seismic shocks greater than magnitude 6, a prediction that they plan to test from seismic stations over the next decade.

"Our paper predicts the change in the rate of small earthquakes for the faults in the region, and now we can test that prediction," said Stein. "If the rate of shocks increases on the adjacent faults, then we can confirm at least part of our hypothesis that large shocks are also more likely. It may take time, but it is a testable hypothesis."

In western China, the intrusion of the Indian sub-continent pushes the Tibetan Plateau up and over the older Sichuan Basin and other parts of the Eurasian continent. An estimated 33 percent of world's continental earthquakes occur in China, even though it only occupies 7 percent of the planet's land mass. Nearly 55 percent of all human loss to earthquakes occurs in China.

"Earthquakes do not kill people, buildings do," said Lin, who was a high school student in China when the devastating Tangshan earthquake struck. "There needs to be widespread education in earthquake preparedness, as well as systematic inspection of buildings in these regions of heightened risk. Every new building inspection and evacuation plan could potentially save lives."

"We hope the long-term forecasting allows the Chinese government to make it a priority to mitigate future damage," Toda added. "We recommend that Chinese scientists carefully observe changes in seismicity by installing new seismometers in the region."

Lin, Toda, and Stein were preparing to teach an earthquake modeling course to Meghraoui's students and colleagues in France when the May 12 earthquake occurred. The researchers immediately went into action, working with an international group of scientists to analyze the new stresses on the system.

An early version of the manuscript by Toda et al was circulated to several dozen Chinese scientists and government officials as they sought to assess the risk of aftershocks in the weeks after the earthquake. Chinese government organizations and scientists are now examining the paper in detail.

"The recent quake reminded us that Earth scientists have a tremendous responsibility to work on issues of societal relevance," said Lin. "We don't want to create panic, but there is legitimate cause for concern and we have a major role to play in educating the public about what we know."

Funding for this research was provided by the Charles D. Hollister Endowed Fund for Support of Innovative Research at WHOI and the EOST-Institut de Physique du Globe de Strasbourg, France.

Pupils to help beaches be safer for summer

SCHOOL children are being targeted as part of a campaign to plug a regional lifeguard shortage.

Intensive beach lifeguard courses are being held in Teignmouth this October half-term after the town's beaches were left short-staffed during the summer.

Teignbridge Council, which received fewer applications this year, hopes the RNLI will take over the running of the lifeguard service from them.

The courses will be run by the RNLI in partnership with Surf Life Saving GB who will teach prospective lifeguards from their local clubs across the south west.

Iain Palmer, president of Teignmouth Beach Surf Lifesaving Club, said the shortage was 'an on-going problem' but he hoped the latest drive to train lifeguards would ease it.

"We have not had a very good season weather-wise, but we have struggled to man beaches because of the shortage. It has been an on-going problem for the last two or three years," he explained.

He said there was a shortage of at least 300 lifeguards across the region in the summer months.

At the moment council lifeguards keep watch on Teignmouth and Dawlish Warren beaches.

Sparse numbers meant some beaches were only manned on weekends during the summer with swimmers relying on coloured flags to guide them.

The shortage meant there was no lifeguard on duty when 42-year-old holidaymaker Nigel Hunt, of Newport, Wales, died after getting into difficulties off waters at Teignmouth on July 24.

The 'no swimming' red flags had been flying because of choppy sea conditions and high winds earlier that day.

But Mr Palmer said he hoped the latest recruitment drive would boost numbers.

"It's a great chance for people to get their qualifications. We hope there are going to be 16 more qualified lifeguards by next summer," he said.

At the moment council lifeguards patrol Teignmouth and Dawlish Warren and the clubs assist on a voluntary basis.

Mr Palmer said he understood the council has been in talks with the RNLI who are going to patrol the beaches from next season.

A Teignbridge Council spokesman confirmed: "There has been a regional shortage of qualified lifeguards, and in Teignbridge we received fewer applications than usual for the posts this year.

"We welcome any initiatives which help train new lifeguards, and hope there are more qualified lifeguards available next year.

"We have been working closely with the RNLI since last year to arrange for them to run Teignbridge's lifeguard service from next season, a move which will also help bring more lifeguards to Teignbridge's beaches and resorts."

The week-long Beach Lifeguard Qualification is an essential requirement for anyone applying for a position as an RNLI lifeguard. Courses will run from Monday, October 27 to Sunday, November 2 and combine practical and theory sessions.

Skills taught will include beach safety operating procedures, hazard awareness, accident prevention, first aid including CPR, and pool and open water rescue skills including sea rescues using equipment such as rescue tubes and rescue boards.

Places on the courses will be allocated on a first come, first served, basis.

Potential applicants must demonstrate a high level of fitness, own their own wetsuit and be able to swim 400m in under seven and half minutes.

Those applicants who gain the Beach Lifeguard Qualification will be able to apply to become a RNLI lifeguard in December in time for the 2009 season.

The course will cost £50. This covers membership of the SLSGB along with the cost of the training manual and examination fees.

Shipping firm sets date to retrieve bodies

OPERATIONS TO remove bodies trapped inside an ill-fated ferry will start on Oct. 24.

Retrieval operations for toxic chemicals that also went down with M/V Princess of the Stars should have been finished at that time, said Jordan L. Go, vice-president for freight of shipowner Sulpicio Lines, Inc.

"Weather permitting, we’re targeting Oct. 24," he said in a phone interview. A series of typhoons has affected operations on the wreck.

Mr. Go said they have yet to sign a contract with Harbor Star Shipping Services, Inc. which will remove the bodies pending the company’s submission of its retrieval plan.

Asked about the cost of operation, Mr. Go said, "It’s difficult to say at the moment because the [salvor] has yet to make an assessment on the location of bodies. There are many variables that we have to consider and we want to make sure that when the salvor execute the plan, it would be comprehensive."

Cool Summer, Warm Future: Extreme Heat Days Increase For Southern California

Cool Summer, Warm Future: Extreme Heat Days Increase For Southern California

ScienceDaily (Sep. 29, 2008) Summer 2008 in Southern California goes down in the books as cooler than normal.

The thermometer in downtown Los Angeles topped 90 degrees Fahrenheit (32.2 degrees Celsius) just once in July, August and the first two-thirds of September.

But don't expect this summer's respite from the usual blistering heat to continue in the years to come, cautions a group of NASA and university scientists: The long-term forecast calls for increased numbers of scorching days and longer, more frequent heat waves.

One hundred years of daily temperature data in Los Angeles were analyzed by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif.; the University of California, Berkeley; and California State University, Los Angeles. They found that the number of extreme heat days (above 90 degrees Fahrenheit or 32.2 degrees Celsius in downtown Los Angeles) has increased sharply over the past century. A century ago, the region averaged about two such days a year; today the average is more than 25. In addition, the duration of heat waves (two or more extreme heat days in a row) has also soared, from two-day events a century ago to one- to two-week events today.

"We found an astonishing trend – a dramatic increase in the number of heat waves per year," says Arbi Tamrazian, lead author of the study, and a senior at the University of California, Berkeley.

Tamrazian and his colleagues analyzed data from Pierce College in Woodland Hills, Calif., and the Los Angeles Department of Water and Power in downtown Los Angeles. They tracked the number of extreme heat days and heat waves from 1906 to 2006. The team found that the average annual maximum daytime temperature in Los Angeles has risen by 5 degrees Fahrenheit (2.8 degrees Celsius) over the past century, and the minimum nighttime temperature has increased nearly as much. They also found that heat waves lasting six or more days have been occurring regularly since the 1970s. More recently, two-week heat waves have become more common.

The team forecasts that in coming decades, we can expect 10- to 14-day heat waves to become the norm. And because these will be hotter heat waves, they will be more threatening to public health.

"The bottom line is that we're definitely going to be living in a warmer Southern California," says study co-author Bill Patzert, a JPL climatologist and oceanographer. "Summers as we now know them are likely to begin in May and continue into the fall. What we call 'scorcher' days today will be normal tomorrow. Our snow pack will be less, our fire seasons will be longer, and unhealthy air alerts will be a summer staple.

"We'll still get the occasional cool year like this year," Patzert continued, "but the trend is still towards more extreme heat days and longer heat waves."

So what's behind this long-term warming trend? Patzert says global warming due to increasing greenhouse gases is responsible for some of the overall heating observed in Los Angeles and the rest of California. Most of the increase in heat days and length of heat waves, however, is due to a phenomenon called the "urban heat island effect."

Heat island-induced heat waves are a growing concern for urban and suburban dwellers worldwide. According to the U.S. Environmental Protection Agency, studies around the world have shown that this effect makes urban areas from 2 to 10 degrees Fahrenheit (1 to 6 degrees Celsius) warmer than their surrounding rural areas. Patzert says this effect is steadily warming Southern California, though more modestly than some larger urban areas around the world.

"Dramatic urbanization has resulted in an extreme makeover for Southern California, with more homes, lawns, shopping centers, traffic, freeways and agriculture, all absorbing and retaining solar radiation, making our megalopolis warmer,” Patzert said.

These trends may capture the attention of utility companies and public health officials. "We'll be using more power and water to stay cool," says study co-author Steve LaDochy of California State University, Los Angeles. "Extreme heat, both day and night, will become more and more dangerous, even deadly."

The findings are published in the July 2008 issue of the Yearbook of the Association of Pacific Coast Geographers. JPL oceanographer and climate scientist Josh Willis was also a co-author on the research.

Hurricane Ike’s effects linger in the Great Lakes

Although Hurricane Ike is long gone, its impact lingers more than a thousand miles from where it made landfall. Runoff from tributaries dumped massive amounts of sediment into Lake Michigan, contaminating the water, compromising near-shore navigation and raising E coli bacteria to levels unsafe for swimming.

According to Richard Whitman, a U.S. Geological Survey (USGS) expert on beach health, 'The local effects that Ike had on Lake Michigan's Indiana shoreline, water depth, and water quality have been profound.'

While assessing Ike's impact on the lake, Whitman noted that 'The velocity and height of a tributary emptying into Lake Michigan at Portage, Indiana went off the chart. We measured a tremendous amount of sediment accumulation Near Ogden Dunes.'

USGS scientists use high tech, state-of-the-art equipment in the lake to measure runoff, the lake's currents, and sediment input during storms. These data are used to forecast whether a beach is unsafe for swimmers. Beaches are subject to high bacteria levels following storms.

Heavy rains from Ike significantly impacted northwestern Indiana and Chicago because the ground was already saturated by a stalled cold front.

Boat users risking their lives by not following safety advice

Over the last few days a number of small vessels have been given assistance by Coastguards and Lifeboats after they were taken to sea without having even the basic safety equipment for communicating a problem on board. Fortunately all aboard were rescued without harm to themselves or their boats. It is VITAL, even when taking a small boat a short distance off shore, that some means of communication is carried. The best means is a VHF Radio with channels specifically selected for maritime use. Flares are also desirable and when these are fired can be seen for quite a distance. Even a mobile telephone is better than nothing, but beware once a mobile phone gets wet it is useless and communications can be very erratic at sea with cliffs, headlands etc. interrupting the signal strength, and remember your phone is only good to use, even in an emergency call ‘999’, if you are in the footprint of an aerial of your network provider.

( Have you ever seen an aerial at sea???? )

Gustav found one gap in marine industry hurricane preparation

The breaking of their moorings by three vessels in the New Orleans Industrial Canal--more correctly the Inner Harbor Navigation Canal (IHNC)-- during Hurricane Gustav appears to have been an isolated exception to the general effectiveness of maritime industry preparations for the storm.

The Gulf Intracoastal Canal Association says that the Coast Guard, Corps of Engineers and inland barge industry have collaborated extensively since the 2005 hurricane season to better prepare for and respond to hurricane events along the Gulf Coast.

Specifically, the collaboration produced a detailed, written protocol for storm preparation, communications and response efforts as they pertain to the marine industry, including rigid procedures for evacuating vessels in advance of a storm, or securing vessels in-place when evacuation is not feasible.

The protocol proved effective during Hurricane Gustav, with the exception of the isolated incidents inside the Inner Harbor Navigation Canal (IHNC).

In the New Orleans area, the hurricane protocol originally focused on the vulnerable reach of the Lower Mississippi River below the Port of New Orleans. Knowing that a planned closure of the IHNC Lock in the summer of 2008 could pose additional challenges to the marine industry's storm preparation and evacuation efforts, the Corps of Engineers and Coast Guard called for a special meeting with the inland barge industry in the spring of 2008 to address potential problems.

During Hurricane Gustav, three vessels that were docked in the Inner Harbor Navigation Canal broke from their moorings, posing potential threat to nearby structures. These vessels were not in active service, and were not owned by any company actively involved in maritime commerce. It is presumed these vessels had been decommissioned and were destined for scrap. A thorough investigation will determine the ownership of these vessels and the reasons why they failed to remain secured during the storm.

Of all the inland barge vessels that were in active service and located within the New Orleans jurisdiction of protocol as Hurricane Gustav approached, ninety-five percent complied with advisories to evacuate the area, and none remained in the IHNC during the storm. As a result, virtually no damage was inflicted by loose barges that were in active service on this reach of the waterway.

The Coast Guard, Corps of Engineers and inland barge industry went to great lengths to anticipate all sources of risk in the IHNC and address them in advance of the IHNC Lock closure in August, including specific procedures and limitations for securing vessels in the IHNC during a storm. There was obviously a failure inside the IHNC during Hurricane Gustav, and pending conclusion of the investigation, additional measures will be developed in order to avoid recurrence of this event.

The GICA was established in 1905 to promote the concept of a single channel connecting all major Gulf Coast ports. The Gulf Intracoastal Waterway was completed in 1949 as a result of a major collaborative effort. The GICA says it is the only organization focused on promotion, protection and maintenance of the Gulf Intracoastal Waterway.

Why Disasters Are Getting Worse

Why Disasters Are Getting Worse

In the space of two weeks, Hurricane Gustav has caused an estimated $3 billion in losses in the U.S. and killed about 110 people in the U.S. and the Caribbean, catastrophic floods in northern India have left a million people homeless, and a 6.2-magnitude earthquake has rocked China's southwest, smashing more than 400,000 homes.

If it seems like disasters are getting more common, it's because they are. But some disasters seem to be affecting us in worse ways — and not for the reasons you may think. Floods and storms have led to most of the excess damage. The number of flood and storm disasters has gone up 7.4% every year in recent decades, according to the Centre for Research on the Epidemiology of Disasters. (Between 2000 and 2007, the growth was even faster, with an average annual rate of increase of 8.4%.) Of the total 197 million people affected by disasters in 2007, 164 million were affected by floods.

It is tempting to look at the lineup of storms in the Atlantic Ocean (Hanna, Ike, Josephine) and, in the name of everything green, blame climate change for this state of affairs. But there is another inconvenient truth out there: We are getting more vulnerable to weather mostly because of where we live, not just how we live.

In recent decades, people around the world have moved en masse to big cities near water. The population of Miami-Dade County in Florida was about 150,000 in the 1930s, a decade fraught with severe hurricanes. Since then, the population of Miami-Dade County has rocketed 1,600%, to 2,400,000.

So the same-intensity hurricane today wreaks all sorts of havoc that wouldn't have occurred had human beings not migrated. (To see how your own coastal county has changed in population, check out this cool graphing tool from the National Oceanic and Atmospheric Administration.)

If climate change is having an effect on the intensities of storms, it's not obvious in the historical weather data. And whatever effect it is having is much, much smaller than the effect of development along coastlines. In fact, if you look at all storms from 1900 to 2005 and imagine today's populations on the coasts, as Roger Pielke Jr., and his colleagues did in a 2008 [ITALIC "Natural Hazards Review"] paper, you would see that the worst hurricane would have actually happened in 1926.

If it happened today, the Great Miami storm would have caused from $140 billion to $157 billion in damages. (Hurricane Katrina, the costliest storm in U.S. history, caused $100 billion in losses.) "There has been no trend in the number or intensity of storms at landfall since 1900," says Pielke, a professor of environmental studies at the University of Colorado. "The storms themselves haven't changed."

What's changed is what we've put in storms' way. Crowding together in coastal cities puts us at risk on a few levels. First, it is harder for us to evacuate before a storm because of gridlock. And in much of the developing world, people don't get the kinds of early warnings that Americans get. So large migrant populations — usually living in flimsy housing — get flooded out year after year. That helps explain why Asia has repeatedly been the hardest hit area by disasters in recent years.

Secondly, even if we get everyone to safety, we still have more stuff in harm's way than ever before. So each big hurricane costs more than the big one before it, even controlling for inflation.

But the most insidious effect of building condos and industry along water is that we are systematically stripping coasts of the protection that used to cushion the blow of extreme weather. Three years after Katrina, southern Louisiana is still losing a football field's worth of wetlands every 38 minutes.

Human beings have been clearing away our best protections all over the world, says Kathleen Tierney, director of the Natural Hazards Center at the University of Colorado, Boulder. "The natural protections are diminishing — whether you're talking about mangrove forests in areas affected by the Indian Ocean tsunami, wetlands in the Gulf Coast or forests, which offer protection against landslides and mudslides."

Before we become hopelessly lost in despair, however, there is good news: we can do something about this problem. We can enact meaningful building codes and stop keeping insurance premiums artificially low in flood zones.

But first we need to understand that disasters aren't just caused by FEMA and greenhouse gases. Says Tierney: "I don't think that people have an understanding of questions they should be asking — about where they live, about design and construction, about building inspection, fire protection. These just aren't things that are on people's minds."

Increasingly, climate change is on people's minds, and that is for the better. Even if climate change has not been the primary driver of disaster losses, it is likely to cause far deadlier disasters in the future if left unchecked.

But even if greenhouse gas emissions miraculously plummet next year, we would not expect to see a big change in disaster losses. So it's important to stay focused on the real cause of the problem, says Pielke. "Talking about land-use policies in coastal Mississippi may not be the sexiest topic, but that's what's going to make the most difference on this issue," he says.

WEATHER NOTE

After Hurricane Ike, Finding the Coastline Rearranged, Again

From the plane flying over the Gulf Islands National Seashore, scientists from the United States Geological Survey were scanning the ocean, trying to find Ship Island. Their maps and G.P.S. system told them they were over its eastern end, but there was no sign of it.

“I don’t see Ship anywhere,” said Asbury H. Sallenger, a oceanographer at the Geological Survey who was sitting in the co-pilot’s seat and had the best view. "On the map we see it, but all I see is breakers. There is just zip left of this thing."

Eventually, the scientists spotted the western part of Ship, but its eastern half had all but disappeared. A small patch of land and whitecaps breaking on underwater shoals were all that remained.

The damage was considerable, but it was the kind of land loss they would see often on their flight, which they made about 48 hours after Hurricane Ike struck the Gulf Coast, as part of the survey’s long-standing effort to track storm damage on the coast.

The geologists should not have been surprised. Scientists studying the way stormy weather erodes the coast have long been able to identify regions at risk for inundation if sea-level rise continues, an inevitability in a warming world.

For example, researchers have estimated that large stretches of another barrier chain, the Outer Banks of North Carolina, will vanish if seas rise more than two feet, which many scientists consider quite likely by 2100.

But on the Gulf Coast, “we are not talking 100 years,” Dr. Sallenger said, “we are talking three years,” the time since Hurricane Katrina and a parade of other storms, including Hurricanes Gustav and Ike this year, virtually destroyed several islands running west into Louisiana. Among them are the Chandeleur Islands, a barrier chain formed thousands of years ago in a now-defunct delta of the Mississippi River, and other islands in the Breton National Wildlife Refuge.

Storms and climate change are partly to blame. But the region as a whole is subsiding. And in some areas, some critics contend, federal dredging projects are robbing islands of sand.

The result is a chain of feeble island remnants. In many places, as Dr. Sallenger observed at one point, “there ain’t nothing here but white water.”

So Karen Morgan, a geologist at the Geological Survey making still photos of the landscape, at times found herself instructing the pilot, Rob Kent, to navigate not by a shoreline but by a line of white water breaking over the submerged shoals that are the islands’ remains. In some places, there were not even breakers to show where dry land had been.

These islands are uninhabited, but they are valuable nonetheless, and not just for storm protection. With their extensive dunes and vegetation, the islands were once an important nesting place for brown pelicans and a variety of other birds. In the last few years, Dr. Sallenger said, the Chandeleurs have lost about 85 percent of their land mass, and with this loss “the habitat for birds on the flyway has decreased by an enormous percentage.”

Of course, the islands have not vanished altogether. And the scientists, who fly this coast regularly, have many times seen islands in these chains erode in storms and then recover — at least somewhat. But that can happen only as long as their underlying platforms of marsh remain intact, providing a place for sand to collect. In many places today, those platforms are “frail and really beaten down,” Dr. Sallenger said.

Dr. Sallenger said the Geological Survey scientists would try to advise officials at the Fish and Wildlife Service, which administers the refuge, what they could expect in the next 5 to 10 years. The outlook is grim.

Storms have already lopped miles off each end of the largest island in the Chandeleur chain. Will the islands bounce back? “We are going to look at the data again,” Dr. Sallenger said. “It looks very tenuous.”

The outlook for Ship Island is similarly daunting, in large part because of the difficulty of finding the necessary sand. “This is a very big operation to put this back together,” Dr. Sallenger said. “It’s not a small deal.”

Scientist Uncovers Miscalculation In Geological Undersea Record

Scientist Uncovers Miscalculation In Geological Undersea Record

ScienceDaily (Sep. 13, 2008)

The precise timing of the origin of life on Earth and the changes in life during the past 4.5 billion years has been a subject of great controversy for the past century.

The principal indicator of the amount of organic carbon produced by biological activity traditionally used is the ratio of the less abundant isotope of carbon, 13C, to the more abundant isotope, 12C. As plants preferentially incorporate 12C, during periods of high production of organic material the 13C/12C ratio of carbonate material becomes elevated. Using this principle, the history of organic material has been interpreted by geologists using the 13C/12C ratio of carbonates and organics, wherever these materials can be sampled and dated.

While this idea appears to be sound over the last 150 million years or so, prior to this time there are no open oceanic sediment records which record the 13C/12C ratio, and therefore, geologists are forced to use materials associated with carbonate platforms or epicontinental seas.

In order to test whether platform-associated sediments are related to the global carbon cycle, a paper by University of Miami Professor Dr. Peter K. Swart appears in the Proceedings of the National Academy of Sciences. This paper examines changes over the past 10 million years at sites off the Bahamas (Atlantic Ocean), the Maldives (Indian Ocean), and Great Barrier Reef (Pacific Ocean). The variations in the 13C/12C ratio are synchronous at all of the sites studied, but are unrelated to the global change in the 13C/12C ratio.

It appears that records related to carbonate platforms which are often used throughout the early history of the Earth are not good recorders of the 13C/12C ratio in the open oceans. Hence, the work presented suggests that assumptions made previously about changes in the 13C/12C ratios of carbonate sediments in the geological record are incorrect.

"This study is a major step in terms of rethinking how geologists interpret variations in the 13C/12C ratio throughout Earth's history. If the approach does not work over the past 10 million years, then why would it work during older time periods?" said Swart. "As a consequence of our findings, changes in 13C/12C records need to be reevaluated, conclusions regarding changes in the reservoirs of carbon will have to be reassessed, and some of the widely-held ideas regarding the elevation of CO2 during specific periods of the Earth's geological history will have to be adjusted."

The study is funded by the National Science Foundation and the Comparative Sedimentology Laboratory at the University of Miami.

Climate: New spin on ocean's role

New studies of the Southern Ocean are revealing previously unknown features of giant spinning eddies that have a profound influence on marine life and on the world's climate.

These massive swirling structures � the largest are known as gyres - can be thousands of kilometres across and can extend down as deep as 500 metres or more, a research team led by a UNSW mathematician, Dr Gary Froyland, has shown in the latest study published in Physical Review Letters.

"The water in the gyres does not mix well with the rest of the ocean, so for long periods these gyres can trap pollutants, nutrients, drifting plants and animals, and become physical barriers that divert even major ocean currents," Dr Froyland says.

"In effect, they provide a kind of skeleton for global ocean flows. We're only just beginning to get a grip on understanding their size, scale and functions, but we are sure that they have a major effect on marine biology and on the way that heat and carbon are distributed around the planet by the oceans."

One of the best known large-scale gyres in the world's oceans is that associated with the Gulf Stream in the North Atlantic, notes fellow researcher Professor Matthew England, co-director of the UNSW Climate Change Research Centre.

Donjon responds to Ike

Hillside, N.J. headquartered Donjon Marine Co., Inc. has been playing its part in cleaning up after Hurricane Ike.

Donjon, whose services include marine salvage, heavy lift, dredging and related emergency response, was contracted by the U.S. Army Corps of Engineers through the company's salvage and related services contract with the U.S. Navy, Supervisor of Salvage of Diving, to remove and dispose of debris after Ike's trek through Texas.

DonjonÕs heavy-lift capability is put to the test in cleanup efforts in the wake of Hurricane Ike

To date, this debris has included vessels, containers and upland material, such as sections of houses and local storefronts, which accumulated in the Gulf Intracoastal Waterway just outside Galveston, Texas.

Donjon subcontracted this work to various area-based marine service providers for equipment and labor, while Donjon provided onsite project management, logistical and financial support.

Great Lakes – dry cargo residue discharge

The US Coast Guard issued a press release stating that, next Monday, it will formally propose regulations that will, if adopted, require operators of lake carriers to keep records of loading, unloading, and discharges of dry cargo residue. It will also encourage lake carriers to use control measures to reduce the amount of dry cargo residue entering waters of the Great Lakes. Discharges into certain protected and sensitive waters will be prohibited. Comments on the proposal should be submitted by January 15, 2009. (9/25/08).

Australia – report on ship-fishing vessel collision

The Australian Transport Safety Bureau (ATSB) issued the report of its investigation of a collision between a liquefied petroleum gas (LPG) carrier and a fishing vessel on 30 November 2007 off Queensland. Neither vessel was maintaining a proper lookout and the LPG carrier failed to report the collision and made no attempt to contact the damaged fishing vessel. (9/25/08).

Research team proposes new link to tropical African climate

Research team proposes new link to tropical African climate

The Lake Tanganyika area, in southeast Africa, is home to nearly 130 million people living in four countries that bound the lake, the second deepest on Earth.

Scientists have known that the region experiences dramatic wet and dry spells, and that rainfall profoundly affects the area's people, who depend on it for agriculture, drinking water and hydroelectric power.

Scientists thought they knew what caused those rains: a season-following belt of clouds along the equator known as the Intertropical Convergence Zone (ITCZ). Specifically, they believed the ITCZ and rainfall and temperature patterns in the Lake Tanganyika area marched more or less in lockstep. When the ITCZ moved north of the equator during the northern summer, the heat (and moisture) would follow, depriving southeast Africa of moisture and rainfall. When the ITCZ moved south of the equator during the northern winter, the moisture followed, and southeast Africa got rain.

Now a Brown-led research team has discovered the ITCZ may not be the key to southeast Africa's climate after all. Examining data from core sediments taken from Lake Tanganyika covering the last 60,000 years, the researchers report in this week's Science Express that the region's climate instead appears to be linked with ocean and atmospheric patterns in the Northern Hemisphere. The finding underscores the interconnectedness of the Earth's climate - how weather in one part of the planet can affect local conditions half a world away.

The discovery also could help scientists understand how tropical Africa will respond to global warming, said Jessica Tierney, a graduate student in Brown's Geological Sciences Department and the paper's lead author.

"It just implies the sensitivity of rainfall in eastern Africa is really high," Tierney said. "It doesn't really take much to tip it."

The researchers, including James Russell and Yongsong Huang of Brown's Department of Geological Sciences faculty and scientists at the University of Arizona and the Royal Netherlands Institute for Sea Research, identified several time periods in which rainfall and temperature in southeast Africa did not correspond with the ITCZ's location. One such period was the early Holocene, extending roughly from 11,000 years ago to 6,000 years ago, in which the ITCZ's location north of the equator would have meant that tropical Africa would have been relatively dry. Instead, the team's core samples showed the region had been wet.

Two other notable periods - about 34,000 years ago and about 58,000 years ago - showed similar discrepancies, the scientists reported.

In addition, the team found climatic changes that occurred during stadials (cold snaps that occur during glacial periods), such as during the Younger Dryas, suddenly swung rainfall patterns in southeast Africa. Some of those swings occurred in less than 300 years, the team reported.

"That's really fast," Tierney noted, adding it shows precipitation in the region is "jumpy" and could react abruptly to changes wrought by global warming.

While the scientists concluded the ITCZ is not the dominant player in shaping tropical African climate, they say more research is needed to determine what drives rainfall and temperature patterns there. They suspect that a combination of winter winds in northern Asia and sea surface temperatures in the Indian Ocean have something to do with it. Under this scenario, the winds emanating from Asia would pick up moisture from the Indian Ocean as they swept southward toward tropical Africa. The warmer the waters the winds passed over, the more moisture would be gathered, and thus, more rain would fall in southeast Africa. The theory would help explain the dry conditions in southeast Africa during the stadials, Tierney and Russell said, because Indian Ocean surface temperatures would be cooler, and less moisture would be picked up by the prevailing winds.

"What happens in southeast Africa appears to be really sensitive to the Indian Ocean's climate," Russell said.

The team examined past temperature in the region using a proxy called TEX86, developed by the Dutch contributing authors. To measure past precipitation, the researchers examined fatty acid compounds contained in plant leaf waxes stored in lakebed sediments - a relatively new proxy but considered by scientists to be a reliable gauge of charting past rainfall.

WEATHER NOTE

The Al Gilkes column – Storm chasing in US
BY AL GILKES

TOWARDS THE END of last month, I packed my bags, got a ride to Grantley Adams International, boarded an aircraft and headed north to enjoy some much needed rest and relaxation.

It was the start of my annual holiday with my two sons up North. And as the plane climbed thousands of feet into the vast blue skies, I reclined my seat, stretched my feet out to their fullest extent, afforded by the extra leg room of an emergency exist, closed my eyes for a moment and allowed my mind and body to slowly drain themselves of all stresses.

I prayed that Barbados and the other countries in the region would be spared the ravage of tropical storms and hurricanes while I was away. The truth is I did not want a repeat of what happened three years ago when I broke my holiday to rush back home to prepare for the onset of a hurricane.

I vividly recalled how on that occasion every prediction and projection showed Barbados squarely in the direct path of the massive system that was churning its way westward across the Atlantic threatening death and destruction on an unknown scale.

I will never forget how after watching satellite imagery on TV, which showed the outer bands of clouds already in the vicinity of the island and hearing the American forecaster confidently predict that Barbados would start to feel the full fury by nightfall the next day, I called the airline and booked myself on the next direct flight home.

What mattered then was that my relatives, friends, and all of Barbados were under the threat of hurricane force winds and flooding rain and there was no way I could enjoy the party while that was happening.

Fortunately, as has been the case repeatedly since 1956 when many lives were lost and the island suffered millions of dollars in destruction of property, crops, and infrastructure, by the time I landed at Grantley Adams in the early evening, the hurricane watch had been discontinued after the system shifted gears and switched to another route.

But the saying goes that what ain't catch yuh ain't pass you; and so it was that while relaxing in Boston the second Thursday I was there, I clicked the Weather Channel icon on my laptop's desktop to see what was and what was not only to discover that a storm warning had been issued – not for Barbados but for Massachusetts where I was.

That's right. Hanna was about to blow ashore with 70 mph winds on the Carolina coast the next day, then race up the Atlantic Coast, reaching New England by Sunday morning.

By the Saturday night, the storm, which was blamed for disastrous flooding and more than 100 deaths in Haiti, was dumping tonnes of rain on Boston with some cruel thunder and lighting. However, the movement over land had robbed it of any meaningful wind speeds and apart from flooding in some areas there were no reports of roofs being blown off or of any other damage normally associated with strong storms.

Never would I have believed before then that a tropical storm would follow me from Barbados all the way up north to Boston.

Severe Storms Research Center Boosts Defenses Against Twisters

The tornado that ripped through downtown Atlanta on March 14, 2008, produced a death, psychological shock and some $150 million in damage. Yet it was hardly an isolated event.

Georgia ranks high among tornado-plagued areas of the United States. It was 18th among the most affected states between 1953 and 2004. And in 2007, Georgia experienced 42 twisters; only seven states suffered more hits.

Helping to protect Georgia residents against such violent weather is the job of the researchers of the Severe Storms Research Center (SSRC) at the Georgia Tech Research Institute (GTRI). One of their tasks: to explore and develop new technologies able to improve both the accuracy and the timeliness of tornado warnings.

Currently, NEXRAD Doppler radar technology is state-of-the-art in the U.S., which is ravaged by more tornadoes than anyplace else on Earth. NEXRAD offers about a 15-minute average advance warning that a tornado may hit.

"That’s a big improvement over the old days, when a funnel cloud on the horizon was often the first warning,” said John Trostel, deputy director of the SSRC. “Before NEXRAD was established in the 1990s, you would have been lucky to have gotten a 30-second warning.”

The GTRI center was founded after a tornado struck Gainesville, Ga., with no warning in March 1998, leaving 11 people dead in Hall County, recalls SSRC Director Gene Greneker. A task force formed by then-Georgia Gov. Zell Miller recommended a severe-storms center with several missions, including conducting cutting-edge research, collecting and archiving storm data and improving detection and warning. The center was initially funded through the Federal Emergency Management Agency (FEMA), and on-going support has come through the state of Georgia with the continuing involvement of the Georgia Emergency Management Agency (GEMA).

"Part of our goal is to explore what’s different about the severe storms of north Georgia,” Greneker said. “Tornadoes in Georgia are often short-lived events that take place over a few minutes, while those in Kansas or Oklahoma may last for an hour.”

NEXRAD continues to be the first line of tornado defense, Greneker explains. Earlier weather radars dating back to the 1950s could sometimes reveal the classic “hook” echo on some tornadoes, but NEXRAD is far more effective.

Today’s national network of NEXRAD stations uses three-dimensional Doppler technology to detect wind direction and other factors; the information shows up on-screen in brightly colored cells that resemble the pixels of a heavily magnified digital photo. When winds in a given area begin to twist in opposite directions - a tornadic phenomenon called wind shear - two cells form a distinctive on-screen “couplet” that alerts weather watchers a tornado may be forming.

SSRC uses several tools to amass and study NEXRAD data, including GR2Analyst software, developed in Georgia, and a WDSS-II analysis station.

"I’m seeing very interesting trends in the number of tornadoes that occur annually in Georgia,” Trostel said. “There was an average of about 15 to 25 events from 1950 through 1970, then a peak in the early 1970s to over 40 events, and then a return to 15 to 25. But since 2000, the trend in the number of annual events appears to be again increasing.”

New Insights into Tornadoes

NEXRAD is an important tool, Trostel acknowledges. Yet to increase the weather watcher’s arsenal, and potentially improve warning times and accuracy, GTRI researchers are developing additional approaches to tornado detection and monitoring.

Currently, SSRC studies North Georgia weather using 12 research systems that use a wide variety of instruments, sensors, computers and software, with two more systems under development. Researchers involved in the effort include Greneker, Trostel, Ed Reedy, Tom Perry and Jenny Matthews, as well as a number of students.

Among the SSRC’s top areas of study is the complex role that lightning and acoustics play in North Georgia’s severe storms and in the formation of tornadoes.

Lightning - Researchers based at GTRI’s Cobb County Research Facility are pursuing several approaches that could potentially correlate lightning’s behavior with tornado activity:

Lightning mapping arrays use multiple receiving stations to monitor severe storms as they move through an area. The SSRC and other Atlanta-area weather stations - such as the National Weather Service at Peachtree City - are developing a six-station array that will augment data already coming from an existing array in northern Alabama;

Electric field mills measure the enormous changes in electric fields between fair weather and severe storms, providing important data that can even correlate raindrop size and frequency with other storm parameters;

A lighting polarization ratio station monitors the horizontally and vertically polarized radio-frequency signals created by lightning strokes, providing data on the behavior of cloud- to-cloud and cloud-to-ground lightning. Greater understanding of lightning, especially the less-understood cloud-to-cloud variety, could shed light on tornado formation;

Gamma-ray detectors record the gamma- and X-rays that emanate from lightning strokes, and offer the potential to correlate the appearance of these powerful phenomena with tornado activity.

Acoustic signals - Severe storms emit very low-frequency sounds—in the range of 50 hertz and below, which is analogous to the sonic footprint of an earthquake. Tornado vortices appear to emit these “infra-sounds” in frequencies ranging from 1 hertz down to tenths of a hertz. At the Cobb Country Research Facility, GTRI researchers are building an array of low-frequency sensors that may allow them to identify sonic signatures unique to tornadoes.

Trostel notes that there are myriad ways to study severe storms, many of them surprisingly cost-efficient. He points to a field mill developed by a local high-school student; constructed from such materials as a coffee can, it can detect electrical fields associated with storms.

"This device does a very good job, and it cost $87,” Trostel said. “We want to get Georgia high-school science classes to construct and deploy these detectors - and then we could track storm-related electrical fields as they progress across the state.”

War over water a source of division

Limited water supplies due to a continuing drought and Israeli restrictions are making life even harder for Palestinian farmers For Palestinians the West Bank water crisis is ‘suffocating’ because it affects both families and businesses, ‘whereas Israel is talking about reducing water for recreational purposes, such as ... swimming pools and lawns’ Abdel-Rahman Tamimi

IN THE plains around the village of Bardala, the Israeli-Palestinian tug-of-war over land and water plays itself out in vivid colour. Largely brown Palestinian farms border green fields owned by Jewish settlers, reports Reuters.

Israel and the occupied West Bank have both been hit hard by drought, but Palestinian farmers say Israeli restrictions on their water supplies have made conditions far worse for them than for farmers in nearby Jewish settlements.

In many homes in the West Bank city of Jenin, water has been all but cut off since April. To cope, residents of Jenin and hundreds of villages get their water delivered by truck at sky-high prices.

In US-sponsored peace talks over Palestinian statehood, disputes over water may be overshadowed by more sensitive issues like the future of Jerusalem and refugees. But Palestinian negotiator Saeb Erekat said an accord would be “unthinkable” without agreement on dividing up the region’s water resources. “If you want to have a state, you must have water,” said Palestinian Water Authority chief Shaddad Attili.

In Bardala in the northern Jordan Valley, Ziyad Sawafta says he gets only enough water to plant vegetables and other crops on half his 50ha plot.

To illustrate the disparity, Sawafta, a 60-year-old father of four, points to the thriving citrus grove next door, owned by the Jewish settlement of Mehola and fed with water through a network of irrigation pipes. Sawafta invokes a common Arab saying for illustration. “We get only the ear from the whole camel. The rest of the camel goes to the settlements”.

Israeli Water Authority spokesman Uri Shor said Palestinians get more water than called for under interim peace agreements. He attributed shortages to Palestinians who he said illegally tap into the water system.

Water has long been a scarce resource in the Middle East but the problem is more acute this year. Scant rainfall has further strained supplies already restricted by Israel, which largely controls the West Bank’s three main aquifers.

Water Authority Chief Attili estimated Palestinian farmers in West Bank and Gaza need 250m cu m of water per year purely for irrigation, but get only about 50m cu m a year. The total amount of water that Palestinians get from their own resources and from Israel is estimated at 200m cu m annually.

”People and land are thirsty and we can do little about it,” Attili said.

Palestinian officials say Israel controls some 50 West Bank wells, with a total capacity of 50m cu m per year, directing it mainly to Jewish settlements, which house some 250,000 people.

The Palestinians control about 200 shallow wells in the West Bank, many of them drilled before the 1967 Middle East war in which Israel captured the territory. Those wells produce about 105m cu m per year, but they are meant to supply water to 2.5m Palestinians.

Attili says West Bank Palestinians supplement their own well supplies by buying up to 45m cu m of water from Israel. Another 5m cu m bought from Israel goes to the Gaza Strip, supplementing 50m cu m from an aquifer.

A big part of the problem for Palestinians, officials and human rights groups say, is that the amount of water supplied by Israel, set by quotas in interim peace agreements in the 1990s, has not increased in line with Palestinian population growth.

”That is not fair,” Attili said, adding that the shortages could be alleviated if Israel allowed his authority to drill two or three new wells in the West Bank.

But the Israeli Water Authority believes permitting Palestinians to drill more wells could “ruin” the existing West Bank aquifers. Israeli officials say Palestinians are not the only ones facing water shortages. Underscoring its concerns, Israel’s government has launched a public campaign to discourage residents and businesses from wasting limited supplies.

Head of the Palestinian Hydrology Group Abdel-Rahman Tamimi said there was no comparison between the shortages facing Israelis and those facing Palestinians in the West Bank because some areas do not even have piped water and other areas suffer from irregular access to drinkable water.

He described the West Bank water crisis as ‘suffocating’ because it affects both families and businesses, ‘whereas Israel is talking about reducing water for recreational purposes, such as ... swimming pools and lawns’.

A recent report by the Israeli human rights group B’tselem said Israeli households consumed on average 3.5 times as much water as Palestinian households.

The group attributed the water shortage in Palestinian areas to what it called Israel’s ‘discriminatory’ policy in distributing water resources and restrictions on drilling new wells.

The shortages have translated into brisk business for water delivery trucks in several West Bank areas. Jenin is connected to the water system but dwindling supplies have forced many there to turn to water vendors, whose prices have soared due to heavy demand and limited supply.

A recent UN report found that Palestinians in some of the hardest-hit communities were spending as much as 30%-40% of their income on water delivered by truck. The Israeli Water Authority did not return several calls from Reuters to request similar information about Israeli consumers.

”I have never witnessed such shortage before,” said Hussein Rahhal, a 73-year-old Jenin water vendor, as he stood by his truck in a long queue of similar vehicles waiting to fill their tanks. He added that some Jenin wells have already dried up.

His colleague, Hashem Abdel-Hafith, who nodded in agreement with Rahhal, said he switched off his mobile phone because he could not keep up with callers demanding water.

In Bardala, home to nearly 2,000 Palestinians, farmers remember better days. Bardala had a surplus of water until the late 1970s when Israel drilled three deep wells next to the village’s four shallow wells, causing them to dry up, they said.

Since then, Israel has reduced the amount of water it pumps to Bardala’s farms, from 240 cu m per hour to 140, forcing many to slash production by up to 50% and to choose crops such as aubergine and beans that can survive on one watering per week.

Another Bardala farmer Yousef Sawafta said prices were falling because everyone in the village was planting the same drought-resistant crops. “In the past, one could find all kinds of vegetables throughout the year. It is not the same any more,” he said.

MARITIME NOTE

SALVORS TO PRODUCE BEST PRACTICE GUIDELINES

MARINE salvage companies meeting in Malta this week have decided move ahead rapidly to produce best practice guidelines for Marine Casualty Management. The guidelines will intended to assist governments, shipowners and managers, port authorities and other interests directly involved in ship salvage operations.

For several years the International Salvage Union (ISU) has proposed the production of best practice guidelines for Marine Casualty Management (MCM Guidelines). At its Annual General Meeting in Malta, ISU members endorsed the project to complete guidelines for circulation and use by salvors, shipowners and coastal states worldwide. The intention is to complete the guidelines during 2009.

ISU president Arnold Witte said: “There is existing International Maritime Organization (IMO) guidance on the issue of places of refuge. There is also very general IMO guidance on general issues relating to the control of ships in emergency situations. What is missing is specific, comprehensive guidance on best practice throughout the entire casualty management process. The MCM Guidelines will fill that gap and, in doing so, will sharpen and enhance marine emergency response capabilities worldwide. Our intention is to consult with our maritime industry partners when finalising the guidelines.”

The guidelines will include provisions on: Pre-event preparations for effective response Special considerations relating to specific casualty types (for example, collision, fire, grounding) First response actions (shore-side and salvor mobilisation, together with ship-board response) Preparing and implementing the Salvage Plan Progressing the salvage operation (including pollution prevention and public issues) Re-delivery of the casualty Key factors contributing to successful salvage and pollution prevention

ISU members have also decided to call for publication of Lloyds Form Salvage Awards, including the full text of the Arbitrator’s Reasons. Mr Witte said: “It is important that the Lloyds arbitration system is not only entirely fair to all sides but is also seen to be fair. An open policy on publication, should the parties involved in the particular case agree, would amount to a great advance in demonstrating the impartiality, validity and flexibility of the Lloyds Open Form (LOF) system

1938: The 'wind that shook the world' kills 700 here

1938: The 'wind that shook the world' kills 700 here

70 years ago: The 1938 surprise hurricane
.

New England's worst and America's 5th worst

By Walter Brooks

On this day 70 years ago, I was looking out the front window of my parent's home on Route 6 in Woodbury, Conn., as one by one the eight giant elm trees in front of our yard were blown over like twigs by the worst hurricane New England ever experienced. nd my home was 22 miles from the nearest salt water in Long Island Sound.

New England has had 24 hurricanes and 14 tropical storms since 1900, but this one was the worst.

Except for a junior forecaster in the U.S. Weather Bureau who predicted the storm but was overruled by the chief forecaster, the Weather Bureau experts and the general public never saw it coming.

Later that day, the greatest weather disaster ever to hit Long Island and New England struck in the form of a category 3 hurricane. Long Island, New York and New England were changed forever by the "Long Island Express."

Case studies have shown that the next time a storm like the Long Island Express roars through, it might be the greatest disaster in U.S. history.

Nobody saw it coming, and Hitler blew it off the front page


Cape Cod almost "got it" in the 1938 Hurricane
The hurricane of 1938 has been called, "the wind that shook the world". In 1938 the U.S. Weather Bureau wasn't what it is today . Meteorologists depended on the merchant ships and aircraft to forecast the weather. At 2:15 on Wednesday, September 21 1938 a Long Island fisherman saw what he thought was a huge fog bank, then, he realized it wasn't fog. It was a churning wall of water 50 feet high bearing down on the New England coast and thirteen million unsuspecting people, with 200 miles per hour winds. The eye of the hurricane came at 60 mph, the velocity of a tornado. It hit the Connecticut shore a little after 3p.m. and flooded downtown Providence and New Bedford.

Future Oracle reporter on the job
Barns sixty miles inland were white with salt spray the next morning. 700 died and 100,000 were homeless in an era when the population was a quarter of what it is today. Communications and roads to Cape Cod were cut off, but an enterprising young Orleans native and reporter, Mary Smith, at the Providence Journal contacted the French Cable Co. in Brest, France to find out what the conditions were in her hometown. A few years later she and her husband Ed started The Oracle newspaper.

The great New England hurricane of 1938 struck at high tide, which coincided with the highest astronomical tide of the year, pushing a storm surge of 12 to 15 feet across the south coast and up the many bays and inlets including Narragansett and Buzzards Bays. Winds of over 120 mph blew across the coastal regions. The Blue Hill observatory, in Milton MA, recorded a sustained 5-minute wind of 121 mph and a peak gust to 186 mph.

Parts of interior Connecticut and Massachusetts not only bore the brunt of high winds, but also experienced severe river flooding as rain from the hurricane combined with heavy rains earlier that week to produce rainfall totals of up to 17 inches. This resulted in some of the worst river flooding ever experienced in parts of Connecticut and Massachusetts.

This powerful storm caused 564 deaths and over 1,700 injuries. Nearly 9,000 homes and businesses were destroyed with over 15,000 damaged. The boating community was equally devastated with 2,600 boats destroyed and 3,300 damaged.



WHOI as the wave hit Cape Cod, and houses floated through the Cape Cod Canal.

Those who survived the hurricane have extraordinary stories to tell. Everett S. Allen titles one such book of vignettes "A Wind To Shake The World, The Story of the 1938 Hurricane".

The author, a Vineyarder who began his first newspaper job as waterfront reporter at the New Bedford Standard-Times on the day the hurricane hit, captures the essence of shock and despair and at times, humor and irony in the many stories from the three New England states that suffered this freak of nature. The book is available at your public library or be sure to check the Internet used-book sites for this gem of a book. In the preface he writes:

"For two years, I have forced myself -- and countless others -- to see again the sick color of sky and sea on that day, to hear the scream of the wind, which was everywhere.

"To confront anew the shocking, instant obliteration of what had always been assumed permanent and mile upon mile of man's work reduced to rubble.

"And I have forced myself and others to see man himself, face down and weaving like weed in the roiling shallows or open-mouthed and still, half-buried in the damp sand. I have made people weep by asking them to remember what for many of them remains their most terrible day."

"The Long Island Express" kills 700

September 10th, 1938 is the first day the weather disturbance was tracked as a tropical storm. The winds began to intensify to hurricane level on September 15th and within four more days, grew to a category 5 - the highest and most intense and deadly level.

One wonders if we should be thankful that on the day of landfall the storm was at category 4, and as it hit land was reducing to category 3? The death of this storm occurred on the 22nd of September after leaving in its wake close to 700 deaths from the tri-state area and beyond.

Diana Rosenberg, a well-known astrologer from New York, said that her family summer home on Long Island was destroyed and some of their documents were blown hundreds of miles north to the state of New Hampshire.

Then Germany invaded Czechoslovakia

Please note that many of our worst storms have companion events in the day-to-day world. On Sept. 21, 1938, Adolph Hitler gained his first foothold in the Sudentenland.

In addition to the extreme loss of life, the abundant stately elm trees and white church spires, the pillars of many New England communities fell and while the steeples could be replaced, the trees never returned to their original splendor.

A disease - the Dutch Elm disease - killed off the remaining elms.

The 1938 hurricane is the most intense tropical cyclone to strike the United States Atlantic coastline north of North Carolina. Along the Atlantic coast of the United States (north of Florida) - only Hurricanes Hugo (1989) and Hazel (1954) - were more intense at landfall. Every record for wind speed, tidal surge, and barometric pressure in New York, Connecticut, and Rhode Island - can be traced to this single event.

Overall, a six-state area experienced economic difficulties for many years due to the record flooding and many mill towns in New England were inundated.

When the "big one" hit Cape Cod

Paul Gately in the Bourne Courier did a bang-up report on the storm this week:

chester_park-9-22-38_242
A sailboat was tossed to the shoreline north of Chester Park in the hurricane of '38. Bourne Historical Commission.

The catastrophic Hurricane of 1938 hit Bourne on the afternoon of Sept. 21, killing seven townspeople. Selectmen in their report said the storm “tore through an unprepared community; the angry sea irritated by ceaseless winds, arose like one huge wave and approached helpless nearby villages.”

Buzzards Bay shopkeepers were forced to evacuate their businesses due to rising water, and townspeople boarded themselves up in their homes... Bourne Courier.

Life and death after Ike


The mixed political response to Hurricane Ike has reinforced the idea that Texans can't rely on the government for help


As with every storm, Hurricane Ike will be either a boom or bust for politicians. Some will reaffirm the trust that voters placed in them. Others will embarrass their constituents on a national stage. Some politicians shine in the spotlight. Others just crash and burn. Bill White, the mayor Houston, Texas, and Ed Emmit, a Harris County judge, have shone, going so far as to camp out and become dispatchers when relief supplies bottlenecked, leaving people waiting in line for hours for ice that was sitting in a parking lot at a sports arena.

To their south however, Lyda Ann Thomas, the mayor of Galveston, appears to be going through an emotional meltdown. On Tuesday, Thomas announced that Galveston residents would be allowed back on Galveston Island briefly. Predictably to everyone but Thomas and her city manager, thousands rushed back to the island, clogging the major highway with a 10-mile long traffic jam and burning already scarce gasoline. Thomas quickly reversed her decision, leaving thousands of her constituents parked on the highway waiting to enter, justifiably irate.

The next day she was reduced to tears during a meeting of the remnants of the Galveston city council when a council member accused Thomas of showing favouritism by allowing a selected few to return to the island and providing essential services such as tetanus shots to city employees while denying them to residents that remained on the island.

There are some things that have changed about hurricanes in recent years. Hurricane Katrina hangs over the head of every coastal area politician. Nobody wants to be the next Ray Nagin (the mayor of New Orleans), Kathleen Blanco (the former governor of Louisiana) or George Bush. Even Bush doesn't want to be Bush. He took to the airwaves last Saturday morning to send a message that he was aware that a hurricane had struck the fourth largest city in the country.

For his efforts, the Federal Emergency Management Agency (Fema) remains the whipping boy for everything that goes wrong in the aftermath of the storm. "Blame Fema" is the new post-hurricane mantra. I didn't even know Fema existed as a child. Prior to Katrina, most Americans likely didn't know what Fema did, and apparently some local officials still don't know.

Despite news reports to the contrary, most Texans aren't relying on Fema. They are relying instead on what we have always relied on in hurricane country: the FFEMA, the Family and Friends Emergency Management Agency.

Our family disaster response swung into action when I got the call from my mother at 7:00am a week ago. Jefferson County officials had ordered a mandatory evacuation of my hometown in southeast Texas. My parents and extended family hadn't bothered to unpack from their evacuation for Hurricane Gustav a little over a week earlier. My mother wanted to head west toward me, but ended up heading north.

After that initial call, as is typical, the cell phone circuits were jammed and calls could not go through. Text messages became the only reliable means of communication. My parents didn't know how to text message, however. My sister on the east coast sent me a text the following morning that, after travelling overnight, my parents and assorted extended relatives had finally reached Arlington, Texas, where they were near family.

My two sisters who live in Houston messaged that they had decided to ride the storm out. My sister in the suburbs north of Houston lost an oak tree, but they survived Ike with no major structural damage. After a day and a half without electricity however, the novelty of playing board games in the dark got old, and they messaged that they were coming to stay with me in Austin.

Like my family, most people aren't waiting around for the federal or state government. They are clearing their streets, creating their own rudimentary power grids by draping extension cords across streets and driveways to share electricity with neighbours. Family members in unaffected areas are driving into town with coolers full of ices and five-gallon gasoline canisters strapped to roofs of cars and SUVs. It was a bit disconcerting driving on I-35 watching an SUV with six full five-gallon gas canisters strapped on top. Is that safe?

People are doing what they have always done after major storms, they are adapting to the situation. Which is why I taught my 60-something-year-old mother how to text message on Sunday when I drove to check on them at their hotel in north Texas. Cell phone companies can provide GPS, internet service and picture mail, but they haven't quite figured out how to cope with all of the families and friends who clamour for contact with each other in times of disaster.

Mama figured it out in about three minutes. In her exuberance in sending and receiving messages I had to caution her that text messaging is not part of her cellular plan. Her newly discovered modern day Morse code was probably costing her $0.15 a message. She didn't appear to care. Contact with the outside world was more than worth it.

MARITIME NOTE

The New Maritime Arctic

A lecture given by
Dr Lawson Brigham

At the Institute of Marine Engineering Science & Technology (IMarEST)

8 September 2008

The Arctic Ocean is about five times the size of the Mediterranean. It has a large continental shelf, possibly the largest in the world, yet is approximately 2 miles deep at the North Pole.

Google Image Result for http___www.pelagic.co.uk_maps_arcticdests.jpg.jpg16 September 2007 marked the minimum extent of polar ice in recorded history. The North West Passage was open for 16 days in 2007. The North East Passage (also known the Northern Sea Route (‘NSR’)) was open but even then needed strengthened, ice-capable ships to navigate the ice that remained.

The last fifty years have seen a steady decrease of ice in all seasons both in extent and also in the thickness. The average depth of the pack ice from the Barents Sea to the Baring Sea is approximately 1.8 metres to 2 metres in mid-winter.

Paradoxically, there is actually more ice this year than there was in 2007 although Dr Brigham was at pains to stress that the overall trend is for less ice, both in extent and in thickness.

He also said that, for reasons that are not yet readily explained, the age of the ice is changing too. The older ice, which has had most of the salt leached out of it and is much harder to break up by ships, is disappearing and being replaced by much younger ice. This leads to an increase in the ability of ships to use the circumpolar waters.

Uses of the Arctic Region

Dr Brigham then went through the five main uses of the Arctic as follows:

Hard minerals

Zinc and coal in Alaska - The largest zinc mine in the world is in Alaska and in the ice-free periods of the year some of the largest ships in the world dock there to load zinc. In eastern Canada, in Baffin Bay, one of the largest warehouses in the world holds iron ore deposits from the very large fields in the hinterland. Again, when the ice clears, some of the largest ships in the world sail there in order to load the iron ore and there is a regular trade route between Eastern Canada and the North West region of Russia (Murmansk and Norilsk).

Nickel and Copper in North West Russia - The largest nickel mine in the world is just near Norilsk.

Marine Tourism

There is an increasing amount of tourist activity in the polar regions. There have been 77 trips by ice-breaking ships to the North Pole itself although tickets are steep at somewhere in the region of US$30,000-$40,000 for each passenger (although there seems to be no shortage of applicants).

There is a certain amount of activity in the North West Passage, too, but this is of the lighter impact variety, mainly eco-tourism.

The more worrying type of activity is the non-ice capable ships that are now beginning to cruise in Greenland waters, these being mainly vessels that can and do normally potter around the Mediterranean and the Caribbean and are simply not capable of withstanding the heavy weather and extreme conditions that can prevail in Arctic waters even in summer.

Fisheries

Especially in the Barents Sea and the Baring Sea – as stocks get over-fished in the other main fisheries of the world there are increasing signs that the large fleets are moving ever northwards.

Oil and gas

This is the big driver, especially in the Chukchi Sea and the Beaufort Sea, and there has also been a massive increase in developments in North West Russia. Dr Brigham said that the relationship between Russia and Norway over the area disputed between those two countries is going to be critical in the coming decades.

Offshore exploration by scientists

Again, although this is relatively minor compared to the oil and gas expansion, there has been a significant increase in the amount of work carried out by scientists in the Polar Region and this is only likely to expand.

Arctic activity

A major problem for the region is that most of those interested in the Arctic are non-Arctic nations.

Although some countries appear not to know how many ships they have in the Arctic at any one time, the general consensus is there are probably about 5,000 ships active in the area each year.

To get some idea of the increase in activity by non-Arctic entities, consider that in 2005 there were 53 cruises in Greenland waters, in 2006 150 and in 2007 there are estimated to be over 200. Almost all of these come from non-Arctic countries and many fly under flags of convenience.

Most traffic in the Russian area is confined to the North West of the country, between and around Norilsk, Dudinka and Murmansk. It is odd but probably not that surprising to note that traffic on the North Sea route (NSR) is down from three hundred and thirty-one thousand trips in 1984 (when Soviet power was at its height) to around about fifty-four thousand now.

In terms of trade consider that from Hamburg to Yokohama can be done in one of the following ways:

  • Northern Sea Route — 7,000 miles
  • Suez — 11,000 miles
  • Panama — 12,500 miles
  • Cape of Good Hope — 14,500 miles

The potential for significant cost and time benefits in opening up the NSR is plain. However, the corollary of that is that vessels would be much more expensive, being ice-strengthened and their speed would be generally lower than coventional ships on conventional routes as they have to go more slowly through pack icE.

Risk scenarios

Dr Brigham said that the Arctic Marine Shipping Assessment (AMSA) of which he is one of the Chairs, had engaged in some scenario planning and had come up with the following not entirely unlikely events that might happen:

  1. a collision between a tanker and a trawler in the Norway/Russia disputed region;
  2. a fire on an oil rig in the Canada/US region;
  3. a barge laden with explosives running aground near an indigenous settlement in the Canadian North;
  4. a giant ore carrier sinking at the North Pole, flying under a flag of convenience and uninsured; and
  5. a large cruise ship grounding off Greenland carrying 2,000 passengers and 900 crew.

reuters-pics-of-yr-07-mv-explorer.jpg (JPEG Image, 414x310 pixels).jpgThis last one Dr Brigham said he thought particularly realistic and worrying, and he referred to the sinking of the Antarctic cruise ship Explorer on 23 November 2007. That incident had involved no loss of life but it should be remembered that that was a smaller and more weatherly vessel than many of the ships cruising in Greenland waters, that the weather was unusually good at the time of the incident and that they had had great good luck in that a Danish vessel happened to have been nearby.

Nordnorge_with_penguins_-_reduced_for_web.jpg (JPEG Image, 336x337 pixels).jpgHe said that the probable scenario with the passengers on such a vessel was that there would be sufficient life boats to get them off but that the 900 or so crew would be left to their fate aboard life rafts of which there might not even be enough. In those waters even without submersion hypothermia begins to set in after about six to eight hours even in high Summer and so one could be looking at potentially a very large casualty rate.

He also pointed to the fact that in these waters, which are well off the normal beaten track for these sorts of cruise ships, there is no infrastructure, no support, no nearby hospitals, no easily available search and rescue facilities, the nearest salvage being five to six days away. All you needed was to have a fire, such as could break out anywhere on a cruise ship, involving say twenty to fifty people being badly burned and you might find that they would all die and more that the ship might be left stranded there subject to even worse events.

Drivers of activity

Commodities and their prices will drive the future of the Arctic at least in the short term. A USGS survey report was published in July 2008 which gives figures about the amount of oil, natural gas and minerals that are expected to be found in the Arctic as percentages of the world’s known deposits. Some of these really are rather speculative (how can one have a “100% probability” of oil being discovered in a certain place?).

There are also ecological issues and recently the power of ethnic groups and ecologically interested parties to stop and slow down the exploration/exploitation of the Arctic has been seen in Alaska where exploration has been brought to a halt by a series of law suits. A choke-point in the Baring Straits in particular could be susceptible to direct action in certain circumstances.

Another issue is that of pollution and emissions. There is some evidence, apparently, that normal emissions by ships have a much more deleterious effect in the Arctic, i.e. the very fact of operating in that particular climate makes the effect of the pollution much worse than it would do at, say, the Equator.

There are also legal wrangles over the rival claims to Exclusive Economic Zones. UNCLOS Article 76 provides that 200 miles from each country into the sea is effectively a private zone for that country. However, the US did not sign UNCLOS and the later Ilulissat Declaration – which was agreed by Canada, Denmark/Greenland, Norway, Russia and the USA – held that there was “no need for any further specific Arctic Treaty”. This, said Dr Brigham, struck him as odd and not altogether desirable.

High Technology Finland | New Materials & Processes.jpgAnother factor is the new ship technology and in particular a new breed of Finnish built ships which operate without rudders but with propulsion systems at each end, the idea being that they proceed ahead in open water but stern ahead in ice. One such vessel is already being run by the Russians in their Arctic waters and is both very fast and very efficient.
