Harnessing the Tides

Harnessing the Tides

EASTPORT — You don’t need a graduate degree in fluid dynamics or hydrokinetics to appreciate the energy inherent in the sea.

Between waves, currents and tides, the ocean is a powerhouse, an enduring, global source of virtually boundless natural energy.

Researchers and entrepreneurs in Maine and elsewhere are finding that tapping that energy and converting it into electricity is more than a bit of a challenge.

Ongoing research in laboratories at the University of Maine and at field testing facilities in Eastport and at the Maine Maritime Academy in Castine is beginning to yield insights into how best to harness the energy of not only dramatic ocean tides but the water that flows through rivers and creeks.

Since 2004, Ocean Renewable Power Co. (ORPC) has been building and testing prototypes of underwater generators engineered to convert into usable electricity the energy that drives the 18-foot tides of Passamaquody Bay.

The firm’s floating laboratory moored in Cobscook Bay and another tidal energy testing site in the nearby Western Passage of Passamaquody Bay have not only proven the concept but have generated new insights into how best to design blades that drive the underwater turbine that began generating kilowatts in April.

“We’re the people who are actually doing tidal energy in Maine,” Chris Sauer says of the company he founded. “We have generated electricity.

“We were initially focused on the current within the Gulf Stream in Florida, but realized quickly there was a better opportunity with tidal currents in Maine.”

The company set up shop in Eastport within a Main Street building that once housed a grocery store. In designing and building its floating laboratory and the electrical and data collection systems it includes, ORPC made use of as many local carpenters, electricians and other skilled workers as it could recruit. The fourth generation of turbine blades were fabricated at the Husson College Boat School located within a mile of the test site in Cobscook Bay.

As ORPC moves from prototypes to full-scale production, Sauer envisions the firm as a source of long-term and high-paying jobs for rural Washington County.

“We’ve been blown away by the capabilities of the people in the state of Maine who have helped us with our project,” Sauer said. “Eastport has a long history of shipbuilding, fishing and work related to the maritime industry, which is an absolute requirement for us to grow.”

Sauer said the company’s proprietary, no-emission generating technology appeals to Maine’s values.

“People care about the environment in Maine, and, in rural Maine, they care a lot more about jobs,” he said. “We’re bringing futures to the people of rural Washington County and a chance for families to stay together.”

Bob Lewis, the site manager for the Eastport research stations, said ORPC continues to work collaboratively with faculty and students at both UM-Orono and the Maine Maritime Academy, which is undertaking its own tidal energy research.

“Orono has been helping us with access to their tow tank and with modeling and computer analysis of the performance of various prototypes,” Lewis said. “The field testing allows us to determine how tow tank modeling coincides with the results we see when we’re operating in the bay, 30 feet underwater.”

While the project’s current focus is tidal energy, Lewis sees applications for rivers, streams and even creeks as an energy source at locations far from the electrical grid.

Lewis and Sauer understand that the 2 billion people worldwide who are now without access to electricity represent a significant customer base.

WEATHER NOTE

DEVASTATING HURRICANES: EXPERTS SAY THE JERSEY SHORE ISN'T IMMUNE


Anyone who says it can't happen here, should think twice. So say meteorologists who think the Northeast is due for a direct hurricane strike. That's because it has happened before, not far from the coastline.

The storm that split Long Island on September 21, 1938 packed winds of 115-120 miles per hour, according the weather service, when it hit the southern side of the island. Even more frightening was its 50 miles per hour forward speed, meaning everything in its path was shaken to its core.

The storm surge was estimated between 12 and 16 feet above mean tide, producing a tidal wave that was recorded on seismographs 3,000 miles away. The lower end of Manhattan was under 10 feet of water. The storm devastated Rhode Island and Connecticut, then tore through New England before it ebbed in eastern Canada.

The worst part of all was the lack of warning, leaving post-Labor Day vacationers especially vulnerable along the seacoast.

The U.S. Weather Service mistakenly believing the storm had curved easterly away from shore - there were only sporadic reports from ships in the area to aid their predictions at the time - had predicted a slight chance of rain locally that day.

When the skies cleared on the morning after the storm, 688 people were dead, 4,500 injured and 75,000 buildings in four states were damaged or destroyed.

It was the worst disaster in the history of New York State until September 11, 2001.

New Jersey State Police Sgt. Robert Aponte, a Toms River resident, recently outlined preparations for such an emergency at a forum on the subject in Berkeley Town Hall. The OEM specialist also distributed material showing how to collect the necessities of self-sustainability for three days after a catastrophic event and how to get ready for evacuation.

Aponte told the 70 or so people on hand - only five showed up at a similar meeting in Toms River recently, he said - that watches and warnings would be relayed from the National Weather Service to a manned command center at state police headquarters in West Trenton. The state police would then communicate with county emergency management specialists to prepare for the threat.

Many in the crowd were startled to learn that any property east of Route 9 falls within the SLOSH (Sealand and Overland Surges from Hurricanes) coastal tidal flood zone.

That means any extraordinary event like a powerful northeastern storm or hurricane likely would cause severe flooding in those areas.

Other tidbits gleaned include the fact that two hurricanes - in 1821 and 1944 - were category 4 storms and passed right over New Jersey. Many in the crowd nodded as Aponte showed slides of the 1962 Nor'easter that split Long Beach Island into five sections at the north end in Harvey Cedars. A dozen people died in that storm.

Another one with local impact was the 1992 Nor'easter that joined salt water with fresh water Monmouth Beach, Monmouth County.

A representative of the Ocean County Office of Emergency Management told the crowd that sudden perils like the tornado that destroyed three homes in Holiday City a decade ago can cause havoc in the community.

You should have a plan, where you can go to get out of harm's way, and take care of the elderly or infirmed to make sure they're not left behind in an evacuation. You should work out a mutual aid pact with a friend or relative within an easy drive to help in an emergency. Many refuse to leave their homes to stay with their pets.

Ocean County public shelters now accept pets, even iguanas, but will turn away anyone bringing drugs, alcohol or guns to the shelter. Extra food is also frowned upon.

It is important that medicines or prescription drugs be brought along with special dietary food, a change of clothing, blanket, sleeping bag and pillow for each in the family.

Also, important documents including insurance, stocks, birth certificates and jewelry along with cash, credit cards and checkbook should be brought along.

Scientists: U.S. not prepared for severe weather, climate change

They are lesson the next residents of the ghostly quarter and Congress that the U.S. needs to very recently with doubled its budget on rise above and aura mutate fact-finding, examine they believe impacts the whole from healthiness and security to transportation and civil assurance.

Scientists cannot fully be aware or handle with the impacts of aura mutation without the befitting partisan running, and without funding as thorough point of view and computing. That was the presentation from the University Corporation instead of Atmospheric fact-finding, the American Meteorological league, and the ride out Coalition in a teleconference with reporters today.

In a particularize aimed at the next crop of state leaders, the scientists said “proficiency is cue to reasoning power these impacts, but seedy and aura exploration and operations budgets demand been swiftly or declining since years enough to the budget wars in Washington.”

John Snow, co-directorship of the sick Coalition and dean of the College of Atmospheric and Geographic Sciences at the University of Oklahoma, said there may father been a a pile of skilful intentions in Washington in late years, “But the genuineness is they’ve been unqualified to shoot.”

“The body of laws budget has only been keeping up with inflation, and in some cases has suffered true to life cuts,” said Snow.

The expertise fundamental got a 2% strengthen, not keeping up with inflation, and the ride out and ambience analyse got 0%, effectively a shorten,” he said.

The scientists are making five recommendations they break purposefulness enhance the state’s buoyancy to modest bear up against and aura shift:

Societal suitability: frame course of study, training and communication efforts proper for the utmost promote of beau monde. regulation and executives: put into effect telling administration to certain that these investments are done in the unsurpassed predisposed of the state.

The assay attend? The pile says lawmakers pleasure want to sum up just about $9 billion to the undercurrent $10 billion that is budgeted above the next five years.

Whether it is hurricanes, tornadoes, fires, floods, snow, or drought, 75% of impulsive disasters encompassing the rapturous are triggered aside survive and feeling. That translates to billions of dollars in indisposed cognate losses every year in the in harmony States.

“What we deliver understandable forth in the change chronicle is what we have in mind is needed to study the political entity in behalf of atmosphere shift, to be skilled to take up to promote our discernment,” said Jack Fellows, evil-doing president of the University Corporation on the side of Atmospheric analyse.

Maritime safety not a priority in RP; Coast Guard struggles to stay afloat

KAREN TIONGSON-MAYRINA, GMA News Research
Article posted July 07, 2008 - 05:00 PM
MANILA, Philippines - Ironically, for an archipelago like the Philippines, maritime safety takes a backseat.

What is considered to be the biggest maritime disaster in the world happened on Philippine waters — the 1987 collision between passenger ship MV Doña Paz and oil tanker MT Vector. Post-tragedy reports revealed the dead numbered as many as 4,000, although the official death toll was at 1,856.

The country’s 36,289-kilometer coastline, one of the longest in the world, is being safeguarded by an insufficient number of vessels and aircraft of the Philippine Coast Guard. Worse, 40 percent of these are not operational.

Communication among Coast Guard units is mainly by cellular phone — through text messaging instead of voice calls — supplemented by a limited number of radios.

The agency has yet to experience the fruits of the various foreign-funded projects, but in at least two of these projects — the Global Maritime Distress Safety System (GMDSS) and Maritime Safety Improvement Project Phase III (MSIP-III) — the Commission on Audit bewailed the loss of millions of pesos in wasted funds.

The Coast Guard itself, on its website, has no illusions about its Herculean task: “The enormous task to perform the multifarious functions of safeguarding the country’s vital sea-lanes from maritime lawlessness, preserving its marine resources and promoting Safety of Life and Property at Sea with its limited resources."

' Not ready for sea'

Data from the Coast Guard Action Center show that the agency has 59 vessels and five aircraft, 40 percent of which are either “Not Ready For Sea" or grounded as of July 1.



The United States Coast Guard says a "Not Ready for Sea" evaluation means Coast Guard inspectors identified mechanical, structural, or safety deficiencies serious enough to render the boat not fully capable of performing search and rescue missions.

“We don’t even have an all-weather vessel na kahit bumabagyo pwedeng gamitin," said Coast Guard spokesperson Lt. Commander Armand Balilo. An average of 19 tropical cyclones pass the Philippine area of responsibility every year.

Of the 14 vessels, six are “not ready for sea" (NRFS) including the search and rescue vessels BRP (Barko ng Republika ng Pilipinas) Edsa II and BRP San Juan; auxiliary escorts BRP Corregidor, BRP Kalinga and BRP Limasawa; and patrol gunboat BRP Palawan.

BRP San Juan, BRP Edsa II and BRP Corregidor are on dry dock. BRP Kalinga and BRP Limasawa are undergoing repairs, while BRP Palawan is undergoing engine repair.

The Coast Guard has five aircrafts, but two of these are grounded — the Helo 163 and Cessna 1242.

Of the 31 small craft assigned to the 10 Coast Guard district headquarters, 14 are NRFS.

• All but one of the nine Diesel Fast vessels at the Maritime Security and Law Enforcement Command are NRFS.

• Of the 11 small craft in the Coast Guard District of National Capital Region-Central Luzon, two are NRFS.

• All two small vessels assigned to the Coast Guard District of Central Eastern Visayas in Cebu are NRFS.

• The two Diesel Fast vessels in Southwestern Mindanao, based in Zamboanga City, are ready for sea; each of the DF vessels in the Coast Guard Districts of Palawan and Southern Tagalog are RFS.

• One of the three DF vessels in Western Visayas, based in Iloilo, is NRFS.

• In the Coast Guard District of Southeastern Mindanao, based in Davao, one of the two DFs is NRFS.

• There are no recorded small craft in the Coast Guard Districts of Northern Luzon, Bicol and Northern Mindanao

The Coast Guard is also “borrowing" 14 monitoring, control and surveillance vessels from the Bureau of Fisheries and Aquatic Resources. Of these, three are NRFS.

'Txt lang'

For communication, Coast Guard personnel depend on the ubiquitous cell phone. In many instances, messages are sent through text messaging, said Lt. Commander Daniel Inri Gayosa, head of the Coast Guard Weapons, Communications, Electronics and Information System Command.

Gayosa said the Coast Guard headquarters has distributed cellular phones among the staff manning its 53 stations and more than 200 detachments nationwide. Each cell phone receives a minimum prepaid allowance of P500.

Siyempre, kulang yung load. Kaya presently nagre-rely na lang sa text e," Gayosa said.

Apart from cell phones, the stations are also equipped with HF (high frequency) and VHF (very high frequency) radios. But Gayosa said not all remotely located detachments have radios.

A recent GMA News television report noted that only one radio is working in the operations center of the Coast Guard headquarters in Manila.

Gayosa said the agency’s current inventory of communication equipment is mainly used for administrative communication such as receiving reports from the various units.

“Almost 100 percent — 98 percent — of (the 53) stations have VHF radios pero sa mga detachment, ang conservative estimate 30 percent lang," he said.
“Supposedly, dahil sa remote location ng mga detachment, dapat at least may HF sila. But not all has one."

VHF radios are intended mainly for short-range communications. VHF radio signals operate in “line of sight“ fashion, generally five to 10 miles. To communicate at longer ranges, MF (medium frequency)/HF radios are needed.

Still, Gayosa noted that troubled ships with HF equipment usually call first their parent companies, who will then inform them of the situation.

GMDSS

Maritime communications should have improved had the Global Maritime Distress Safety System (GMDSS) pushed through.

GMDSS, a system initiated by the International Maritime Organization, was designed to enhance ship-to-shore communications and provide rapid automated distress alerting through shore-based facilities for Maritime Search and Rescue Communication Stations in 19 sites nationwide.

The contract to procure equipment amounting to almost P300 million was entered into between the DOTC and French company Thomson CSF NCS-France (later renamed Thales) in 1998. According to the National Economic and Development Authority and the Mindanao Economic Development Council, the project was funded by the French government.

The 2006 Commission on Audit report on DOTC said the contractor abandoned the project in July 2000 “due to a billing dispute" and after more than five years of negotiations between the parties, the termination agreement has yet to be finalized.

In a separate audit report in 2003, COA — citing the GMDSS Project Management Office — noted that out of the P295,854,823.62 worth of delivered equipment, 71.99 percent or P212,981,302.93 was not installed by the contractor.

“The container vans containing the uninstalled equipment located at various project sites are now in the state of deterioration due to long exposure to open environment while the facilities installed in the completed stations are now beginning to deteriorate due to lack of maintenance. Likewise, the unfinished stations/buildings are in danger of imminent collapse and may pose hazard to the public and nearby structures," the COA report said.

“It is worthy to mention that the Department had already expended so much for the above projects and yet no significant progress/development was reported. Such costs and other resources would be wasted and the benefits that could have been derived from the projects could no longer be achieved if the installation of the equipment would not be completed," it added.

Gayosa said the Coast Guard, as end user of the project, is not allowed to use the equipment until those were formally turned over.

But Gayosa said the Coast Guard is expecting next week the arrival of communications equipment from the Japanese grant-aid project Enhancement of Communications System for Maritime Safety and Security.

A Japanese Embassy press release said the 609-million yen project, signed in 2007, aims to establish satellite communications system in 11 stations nationwide, connecting the Coast Guard headquarters and its district offices, “to improve and enhance the PCG’s capability for search and rescue as well as counter-terrorism."

Twenty-four stations, under the Manila, Cebu and Zamboanga District Offices, will also be equipped with VHF/HF Radio System. Six Metro Manila stations will be equipped with Microwave Communications System in and three stations of the Manila coast will be rehabilitated and upgraded.

ODA loan projects

Data from the 2008 Budget of Expenditures and Sources of Financing show that the Department of Transportation and Communications is the implementing agency of at least 14 ODA-funded maritime projects.



Based on data from the Department of Budget and Management, the government is already paying for these projects.

The loans include two French Protocol loans on global maritime safety and five Japan Bank for International Cooperation/Overseas Economic Cooperation Fund (JBIC/OECF) on maritime communication and safety improvement projects.

JBIC’s Maritime Safety Improvement Project (MSIP) is a 3,516-million yen loan for the emergency rehabilitation of navigational aid facilities — 37 lighthouses and light beacons — in the Manila-Cebu sea road and training required for the operation and maintenance of these facilities.

MSIP-2 is a 5,579-million yen loan that also sought the installation and rehabilitation of navigational aid facilities such as lighthouses.

JBIC’s Maritime Communication Project is a 2,633 million-yen loan amount seeking to ensure efficient and reliable maritime communication services by constructing a Manila Central Coast Station consisting of a transmitting station, receiving station and operation center and a Manila Port Station.

It would install maritime radio communication equipment for these stations as well as training equipment and UHF link from the Operation Center to Pagasa and Philippine Ports Authority.

Spain — through Bancaja, one of its largest banks, and Instituto de Credito Oficial (ICO), a lending unit — extended loans for an oceanographic research vessel, MSIP-3 and MSIP-3-1.

New Zealand Banking Group Limited-Export Finance and Insurance Corporation (ANZ-EFIC) provided loans for research and rescue vessels.

The government is still paying for all these loans.

But it appears that the Coast Guard has yet to reap the fruits of these projects.

Defective lighthouses

How these projects will be implemented is another story.

In the 2004 audit of the DOTC, COA said 13 lighthouses — worth close to P52 million — under the first and second batches of the Maritime Safety Improvement Project Phase III (MSIP-III) were defective.

Lighthouses provide navigational safety at sea.

The Mindanao Economic Development Council website said MSIP-3, a Spanish ODA project, involves the acquisition of two maritime accident response vessels and construction of marine accident response and support base in Cebu City. It also includes the construction and rehabilitation of 120 lighthouses nationwide.

Findings of COA technical staff in 2004 on inspection of a total of 13 lighthouses — seven from the first batch and six from the second batch — showed that the light stations “may only be useful for a short period since the defective marine aids-to-navigation equipment may easily cause the light stations to be non-operational."

Nine of the 13 light stations were already not functioning at the time of inspection although they were accepted only last April 2002 and January 2003.

“For the 13 light stations alone, the government had expended the amounts of US$1,089,400 or equivalent to P43,576,000.00 for the defective equipment and P8,345,528.43 for the cost of civil works which may be considered useless due to non-functional/non-operational light stations," the report said.

La Maquinista Valencia, S.A. bagged the US$13,798,888 contract for the supply and delivery of the marine aids-to-navigation equipment. C.T. Leoncio Construction and Trading and Atlantic Erectors Inc. won the contract for the construction of foundation, erection of towers, installation of equipment including lightning protection systems and commissioning of the First and Second Batches, each consisting of twenty-five (25) lighthouses, worth P14,452,870.63 and 20,142,729.05, respectively.

In the 2005 audit on DOTC, COA said the suppliers had been notified in writing about all defective equipment and abnormalities noted in some lighthouses and were asked for replacement.

Insufficient budget

In the 2008 General Appropriations Act, the office of the secretary of the DOTC allotted under operations of “Protection of Philippine Coast" a total of P1,809,623,000 — P1,161,669,000 for personal services, P622,106,000 for MOOE and P25,848,000 for capital outlay. Another P400,000 in MOOE was allotted under “support for operations."

The Coast Guard budget falls under the DOTC's Office of the Secretary under “support to operations" and “operations."

The Coast Guard budget usually increases through supplemental budgets and subsidies, says COA.

The fact that there is no specific line item for the Coast Guard (unlike other DOTC offices such as the Maritime Industry Authority or the National Telecommunications Commission) seems to show that the agency is in the lower rung of the government’s list of priorities.

Kulang talaga," Balilo said, lamenting the Coast Guard resources. “Hindi kami makakapag-perform what is required of us because we lack the facilities, personnel and equipment."

A DBM source said the DOTC secretary is the one seeking ODA loans or grants to augment Coast Guard resources.

In 2007, the Coast Guard received a total allotment of P1.93 billion, based on COA reports.

Of its P1.92 billion expenses that year, P1.37 billion or almost 72 percent was spent on salaries and wages of its 4,000 personnel while P545 million or 28 percent was paid out for maintenance and other operating expenses.

The allotments have actually increased: In 2006, The Coast Guard received P1.82 billion and P1.33 billion in 2005. - GMA News Research

Satellite View Of Cloud Tops Might Warn Of Storms

Satellite View Of Cloud Tops Might Warn Of Storms

ScienceDaily (July 11, 2008)
For three years, a new way to use data collected by NOAA weather satellites has been giving North Alabama short-term warnings of "pop-up" thunderstorms.

Developed by scientists at The University of Alabama in Huntsville, this new computer program is now spreading to other parts of the U.S. and the world. Later this summer a version of the UAHuntsville weather program will begin forecasting storms throughout Central America, Southern Mexico and the Dominican Republic.

The UAHuntsville Satellite Convection AnalySis & Tracking System (SATCASTS) monitors cumulus clouds as they develop, move and grow through time, according to the person who brainstormed the idea behind the program, Dr. John Mecikalski, an assistant professor of atmospheric science at UAHuntsville.

The program uses data from NOAA’s GOES weather satellites to provide 15-minute to one hour warnings of local thunderstorms. This is the first time forecasters anywhere have had a tool to forecast storms that develop locally. This differs from Doppler radar, which only tracks rain after it starts to fall.

"The radar tells you what's happening, but not what's going to happen," said Wayne MacKenzie, a research associate in UAHuntsville's Earth System Science Center and a member of the SATCASTS development team.

Operated by UAHuntsville scientists for the National Weather Service forecast office in Huntsville for about three years, SATCASTS has been accurate in its storm forecasts between 65 and 75 percent of the time. It has successfully identified hazards generated by thunderstorms, including lightning, hail, high wind, flash floods and turbulence.

Mecikalski got the idea for SATCASTS in 2001, when he was affiliated with NOAA’s Cooperative Institute for Meteorological Studies. He was looking for a way to determine which of the thousands of cumulus clouds present on any given summer afternoon will become thunderstorms. (One percent or less of clouds develop into rain clouds.) He has continued his research since joining the faculty at UAHuntsville in January 2004.

Using data from the GOES visible and infrared sensors, SATCASTS tracks changes in both cloud temperature (height) and water vapor. This data is updated every 15 minutes.

The UAHuntsville team has determined that one of the most important factors in predicting thunderstorms is temperature change. If the top of a cloud cools by 4 C (about 7.2 degrees Fahrenheit) or more in 15 minutes, that means the cloud is growing quickly and there is a growing probability of rain beginning within 30 minutes to an hour. A 4 C drop in temperature typically means a cloud top has climbed between 1/4 to 1/3 of a kilometer.

Based on its success in the Huntsville forecast office, scientists at UAHuntsville are working with the National Weather Service to transition SATCASTS into the storm prediction systems in forecast offices in Birmingham, AL, and Nashville, TN, as well as both Melbourne and Miami, FL.

The UAHuntsville team is also working with NASA and the Federal Aviation Administration (FAA) to test SATCASTS' possible utility in aviation and air traffic control. The system is being tested at the FAA’s New York City air traffic control center. If successful, SATCASTS might be used worldwide to warn pilots of storms, turbulence and other weather threats before they occur.

Other organizations evaluating the operational implementation of the SATCASTS algorithm include the European Meteorological Satellite agency and the South African Weather Service. Discussions are also under way to bring SATCASTS capabilities to East Africa.

While SATCASTS joins a sophisticated and extensive network of weather monitoring systems in the U.S., it is expected to have special value in regions where storm forecasting and monitoring have been limited or non-existent. The system is relatively inexpensive to install and operate, since it uses freely distributed weather data from existing satellite sensors.

NOAA-funded research at UAHuntsville will focus on expanding SATCASTS' capabilities. In areas where Doppler radar networks do not exist, SATCASTS might be used in the future to track frontal storm systems and provide severe weather warnings that are not presently available, Mecikalski said.

"This makes SATCASTS and satellite-based rainfall predictions very relevant in many developing countries, when ground-based radar is absent but high quality satellite data are in place."

The UAHuntsville SATCASTS team includes Mecikalski, two other scientists and three graduate students. The project has been supported by more than $1 million in funding from NOAA, NASA and the FAA.

Research on improving SATCASTS is ongoing and is expected to continue for at least five years. New areas of research include 30-to-90-minute lightning and flash flood forecasts.

The UAHuntsville team is also working on a next generation SATCASTS, which will take advantage of the improved sensing systems that will be available when NOAA launches it GOES-R series of satellites beginning in 2016. Sensors on those satellites will collect data in more channels, more often and at higher resolution.

WEATHER NOTE

Thunderstorms and Camping Safety

When folks go camping, whether into the wilderness or just locally, they have to be prepared to deal with whatever weather happens to be going on during their campout. If you've done any camping at all, chances are you've experienced a few thunderstorms, up close and personal in a tent, or while hiking and otherwise enjoying the outdoors.

It's my "day job" to be involved in hazardous weather, mostly from thunderstorms. Thunderstorms have a beneficial side, but on some occasions, they become more than a minor inconvenience for campers and those involved in outdoor activities. Through my Scouting experiences, I've had many opportunities to see how young people and their adult leaders operate during a campout.

Teenage boys are legendary for trying to act "macho" and getting stuck in situations that have become dangerous. Unfortunately, adult leaders sometimes can be just as silly and ignorant as the boys. It's often said "What you don't know can't hurt you." Absolutely wrong!! Ignorance and macho trips can result in terrible tragedies once in a while, and I doubt that anyone would want that on their conscience.

Lightning hazards

Thunderstorms all produce lightning in varying amounts ... sometimes there's just an odd flash or two ... other times, the storms produce lightning nearly continuously, with lots of flashes to ground. It's the flashes from the cloud to the ground (CG flashes, for short) that create problems. They typically are only a small percentage of the total flashes produced by a thunderstorm; most lightning stays within the clouds. But it only takes one CG flash to get you! The human body is basically a bag of salty water, which conducts electricity a lot better than air, so the lightning will often try to travel through you to reach the ground.

Lightning and thunder are so common as to seem just part of the background. Often, as children, lightning and thunder frighten us. As young people mature (especially boys), it becomes a "macho" thing to show they are not afraid of a thunderstorm. Well, I'm certainly not advocating that we over-react, and head for home at the first sign of any thunderstorm ... but I want to suggest that we not go to the opposite extreme and pay virtually no attention to the threat that lightning strikes pose. Any thunderstorm should be a matter of concern, and the campers should already know what to do if the situation becomes hazardous.

It's pretty unlikely that you'll ever be struck by lightning. Scientists cannot make accurate predictions of when and where lightning will strike or how often, so for all practical purposes, it looks pretty random. Nevertheless, more people are killed by lightning year in and year out than by any other weather phenomenon; typically on the order of 100 people or so annually in the United States. Furthermore, lightning does not have to kill you to create major problems in your life. Several hundred people are affected by lightning in the U.S. every year, short of being killed. To get some idea of the non-fatal hazards of lightning from a medical point of view, check out this site and/or this one. Being struck is no joke and can affect you adversely for the rest of your life.

Anytime you're outdoors, you've increased your risk of being struck by lightning. For example, some golfers are struck every year ... many of you may have heard the story of Lee Trevino's non-fatal encounter! Another category of those who are at relatively high risk includes those who climb mountains. Since a lot of wilderness adventure camping includes hiking and camping at high elevations, campers and hikers are considerably at risk, whether they realize it or not. Consider the following statement from the 1997 Philmont Scout Ranch "Guidebook to Adventure": READ MORE

MARITIME NOTE

PRINCESS OF THE STARS : ‘You’re better off texting coordinates’

MANILA, Philippines—The ill-fated MV Princess of the Stars had all the fancy communications systems in the world, but for some weird reasons they all failed when they were needed, except for an antiquated single side band radio and the ubiquitous cell phones.

That’s the contention of Ernelson Morales, safety officer of Sulpicio Lines Inc.

The device that automatically submits a distress signal via satellite didn’t work.

There was no SOS received by maritime agencies or ships that could have immediately gone to the aid of the 860 people aboard the vessel only 56 of whom survived.

The ship also had a Navtex, used to get weather reports from nearby countries, Morales says. But Sulpicio chose to rely on the single side band radio and the cell phone to get reports from the Philippine Atmospheric, Geophysical and Astronomical Administration (PAGASA). Its weather data are more localized, he says.

In addition, the ferry had a medium-frequency, a high-frequency (HF) radio and a very-high-frequency (VHF) radio along with a two-way radio tuned in to the emergency channel and an emergency position indicating radio beacon (EPIRB) that, once immersed in three meters of water, would automatically send a distress signal.

These were all required by maritime regulations, Morales says. “You won’t be allowed to sail if you don’t have complete equipment,” he said.

But apparently, these communication systems proved unreliable when the vessel was getting the brunt of Frank’s fury.

He theorizes that the strong winds damaged the antennas and transmitters, thus rendering the vessel incommunicado.

A distress signal sent by the EPIRB, installed outside the bridge on the top deck, would have been picked up by nearby countries with the capability to receive such data.

Winds knocked out system

“I was wondering why it did not send a signal. My presumption is, since it is outside, the strong winds knocked it out of its position and sent it hurtling against a wall, thus breaking it. That’s the only way for it not to send a signal because it’s automatic,” Morales says.

Sulpicio Lines senior vice president Edgar Go told the Board of Marine Inquiry (BMI) that the company used the single side band and cell phone to communicate with the ship captain during the emergency.

Retired Commodore Amado Romillo, who resigned from the BMI after being accused of being biased by Sulpicio, criticizes the ship’s reliance on the single side band radio to communicate with the ports.

Romillo also says there were hours when nobody was manning Sulpicio’s radio at the port.

The Philippine Coast Guard only has VHF and HF radios and has also taken to relying on cell phones, says PCG spokesperson Lt. Armand Balilo.

“As far as I know, the Philippine authorities have no capability to get the signal from EPIRB. Sometimes we ask, what’s the need for this EPIRB? You’re better off texting your coordinates, get it through your GPS,” Morales said.

P739-M distress system

Under the Global Maritime Distress and Safety System (GMDSS), vessels are required to secure certain communication equipment, including satellite-based ones, which enable them to transmit and receive distress information quickly or automatically, and to receive maritime safety information such as weather reports and navigation warnings.

But along with these requirements for ships, the country’s maritime agency should also have the counterpart equipment.

In 1998, the Department of Transportation and Communications (DoTC) signed a contract for the installation of 19 GMDSS stations nationwide with Thomson CSF NCS-France under a 25-year loan of 106.53 million francs, or P739 million, from the French government at 1.5 percent interest.

“It remains a big mystery why a contract was approved but no useful equipment ever came out of it,” says Sen. Manuel Roxas II, who is calling for an investigation of the deal, which he says could have avoided a string of sea disasters.

“Did the contractor deliver on their obligations, and if so, what happened to the GMDSS? If the winning bidder failed to comply, why didn’t the DoTC run after them? On the finance side, are we still paying off a foreign loan for an invisible GMDSS?” Roxas said, noting a 2006 Commission on Audit report saying the contractor abandoned the project in 2000 “due to a billing dispute.”

‘We really lack equipment’

At present, the Philippine Coast Guard (PCG) is equipped only with 108 VHF and 78 HF radios for communication. Sixteen other VHF radios are not working, says Lt. Cmdr. Daniel Gayosa of the PCG Weapons, Communications, Electronics and Information System Command.

These radios, which are used mostly for administrative matters, are inadequate for the PCG’s 10 districts, 52 stations and 180 detachments in the country’s more than 7,100 islands, Gayosa noted.

“The radios we have are not enough. We really lack equipment, and we have no budget to buy all that we need,” Gayosa says. He says far-flung PCG offices are supposed to be equipped with the HF radios, but many of them lack this basic tool.

Balilo says many Coast Guard detachments have taken to using cellular phones to communicate.

To monitor distress calls, the PCG listens in to the emergency channel on their radios, according to Gayosa. A good number of times, they also learn of maritime incidents through calls relayed by the vessel owners, other ships, local authorities and even international maritime organizations to the PCG’s offices.

The PCG’s land stations also do not have the capability to receive messages from the digital selective calling (DSC) radio, a device that automatically sends a distress alert and the ship’s identification, says Gayosa.

Last year Sid Martin, Director of Technology at Northeast Maritime Institute was faced with a dilemma. He had been hired to spearhead a project bringing the latest technology to the field of Maritime Security and test it in the field. Martin was the perfect candidate for this job. Prior to working at NMI he was a member of the project team responsible for the wheel bearings on the Mars Lander and in doing so became familiar with the obstacles faced in developing products for use in harsh environments. But the project was nearing completion and he needed to find new ways to use his experience at the institute. MORE
