Recreational scuba divers discover the benefits of Nitrox

tdi-nitrox-diver-front Nitrox Diver Course in Thailand

Koh Tao, Thailand

Big Blue Tech celebrates the graduation of Ana Pinto and Mark Barham from the TDI Nitrox Diver course.

The TDI Nitrox Diver course is the most complex and difficult Nitrox course of all those on offer. It’s mandatory that students understand SAC rates, complex dive planning with tracking of both CNS Oxygen Toxicty and OTU’s, the use of equipment for oxygen systems, safety measures and many more topics that have long been discarded in the process of making Nitrox diving more accesible and easy to do.

The course includes a 50 question exam which takes approximately 1 hour. This course gave Ana and Mark who are HSE Scuba Divers a true challenge and a valuable education.

With 2 nitrox dives completed and an afternoon of theory Ana and Mark both move on to their Rescue Diver Course.


Poseidon Discovery – now available for 10,000 diving instructors.

Wednesday, January 20th, 2010

poseidon-discovery-recycles-air_5965-222x300 Poseidon Discovery – now available for 10,000 diving instructors.

TDI (Technical Diving International), the largest technical certification agency in the world, is now offering training in the sports diver Rebreather, also known as Poseidon Discovery. TDI is seen as an innovator always bringing new, exciting and functional diving techniques and programs to the general diving public.

All of the thousands TDI-certificated dive leaders around the world now have the opportunity to get educated in the Rebreather system. This means that the possibility for scuba divers to be taught by an Rebreather-educated instructor has increased considerably.

“I would call this the crucial step för the Rebreather to reach the great amount of recreational divers all over the world,” says Kurt Sjöblom, CEO of Poseidon Diving Group AB. “My prediction is is that 2010 will really be the year of the Rebreather!”

Poseidon was founded by divers, for divers. When Ingvar Elfström launched the world’s first single hose regulator in 1958 it became an immediate sensation. The company currently has 30 employees and over 2000 agents worldwide. Headquarters and manufacturing is located in Gothenburg, Sweden.

The world’s first closed breathing system for recreational divers
Unlike traditional breathing systems for recreational divers, Poseidon Discovery reuses the exhaled breath. This extends the diving time from 40 minutes to several hours. In November 2008, Poseidon Discovery was awarded the international award “Best of What’s New Award” by Popular Science, one of the largest popular science magazines.

Military divers recover WWII remains.

Thursday, November 5th, 2009

aleqm5igqfbadoz0ga43ysblqe0oxuvgiw-300x246 Military divers recover WWII remains.

For two decades after her son’s bomber went down in the Pacific Ocean during World War II, Vella Stinson faithfully wrote the U.S. government twice a month to ask if his body had been found — or if anyone was looking.

The mother of six strapping boys went to her grave without the answer that has finally reached her two surviving sons 65 years later: the remains of Sgt. Robert Stinson are coming home.

Military divers recovered several pieces of leg bone from the wreckage of a B-24J Liberator bomber found at the bottom of the ocean off the coast of the island nation of Palau. DNA testing showed the femur fragments belonged to the 24-year-old flight engineer who died in combat on Sept. 1, 1944.

Stinson’s remains arrived under U.S. Air Force escort Wednesday and will be buried Friday at Riverside National Cemetery with full military honors. In between, the body will be kept at a mortuary less than 100 yards from the home where Stinson grew up with his brothers.

“He’s not someplace on a little island or at the bottom of the ocean. He’s home,” said Edward Stinson, who was 9 when his brother died.

For Robert Stinson, the journey home was far from a sure thing.

Stinson’s family knew only that his bomber had gone down in the Pacific Ocean after being hit by anti-aircraft fire. The government politely responded to his mother’s letters but said again and again that no new information had surfaced.

The family learned that Stinson, who joined the Army Air Forces right out of high school, won several medals in the summer of 1944 for participating in dangerous attacks on Japanese airdomes, military installations and enemy ships. His plane was dubbed “Babes in Arms.”

In 1994, a nonprofit group of adventurers and scuba divers began to search for the missing bomber off the waters of Koror, Palau’s biggest island. The 15-member group, called BentProp, travels to the island nation each year for a month to search for some 200 missing U.S. World War II aircraft.

Half of the wrecks scattered in the waters around the archipelago’s 300 tiny islands have missing crew members associated with them, said Daniel O’Brien, a member of the BentProp team. Stinson’s plane had 11 crew members — and there were eyewitness reports of where it went down. Eight crew members went down with the plane; three parachuted out, but were captured by the Japanese and are believed to have been executed.

The group attended reunions of Stinson’s bomber squadron and the aging veterans told them where they thought they had seen the plane go down as the rest of the formation raced back to base at 200 mph. BentProp members methodically searched that area for six years, but found nothing.

Then, in 2000, several members of the group doing more research stumbled upon obscure black-and-white aerial photos in the National Archives that were taken by a crew member aboard another bomber just moments after Stinson’s plane went down. The team thought it odd the photographer had taken shots when no bombs were falling, and then realized the pictures were probably an attempt to document where the bomber crashed.

The pictures indicated a splash zone eight miles from where BentProp had been looking.

An elderly fisherman bolstered that evidence: he had seen plane wreckage in that area while spear-fishing about 15 years before.

The team dove the site in 2004 and instantly hit a jackpot: a B-24 propeller at 30 feet and then the plane, broken in three parts around a coral head where it had sat for more than 60 years. Debris was scattered at up to 70 feet deep.

The divers quickly turned over their findings to the Joint Prisoners of War, Missing in Action Accounting Command, or JPAC, the government agency that searches for U.S. prisoners of war and missing soldiers.

Military divers soon confirmed the plane’s identity and recovered hundreds of items from the ocean floor, including dozens of tiny bone fragments, a rusted metal eyeglass frame, a tangled parachute cord attached to singed parachute, a shoe sole, coins, dog tags and one intact shoelace.

In 2006, Edward Stinson and Richard Stinson, the other surviving brother, gave DNA samples. On Feb. 1, Richard Stinson got the call: their brother, the 6-foot-4 clown with curly hair and a love of sports and poker, was finally coming home.

Four other missing crew members were also identified through DNA and are being returned to their families. Other remains found at the site were identified as human but were too fragmented to be linked to the three other men aboard, said Air Force Lt. Col. Wayne Perry. They will, however, be memorialized with the entire crew at Arlington National Cemetery next spring.

“There’s finally an ending to it. We never expected something like this,” said Richard Stinson, now 87. “We knew that three of them had gotten out of the plane and … you always hope that the three that got out, that one of them would be him and that maybe he survived.”

With Stinson’s remains coming home, his brothers are overwhelmed with the memories they have stored away all these decades — memories that, until now, are all they had. And, after years of imagining their brother lost and alone at the bottom of the ocean, his brothers have finally found their own peace.

“He hasn’t been lonely the last two, three weeks. He has risen,” said Edward Stinson. “Welcome home, brother.”


Treasure hunters recover ring on wreck of the Atocha

atochaexaminer Treasure hunters recover ring on wreck of the Atocha

A very rare, delicate, gold amethyst ring was recovered on the famed shipwreck site of the Nuestra Senora de Atocha by SCUBA divers in the Caribbean it was announced yesterday.

In the year 1622, 35 miles off the coast of Key West, Florida the Spanish Galleon Nuestra Senora de Atocha sank in a violent hurricane en route from Havana, Cuba back to Spain. Famed underwater treasure hunter Mel Fisher first began searching for this wreck years ago. Today, Fisher’s family and crew continue the search he began for the rear section of the ship, which has been dubbed the Sterncastle. This portion of the ship is known to have held the wealthiest of passengers and thus some of the most precious artifacts and jewelry.

The Fisher’s most recent find, announced yesterday, is a rare gold ring bearing a deep purple amethyst stone. It was found by the seasoned crew of the salvage vessel J.B. Magruder, Captained by Andy Matroci.

It is a rare one-of-a-kind artifact that Kim Fisher describes: “It is a plain gold band with a large box-shaped gold setting on the top with an amethyst inside. The amethyst is so dark it is almost black. It probably would have come from a large crystal in order to be that dark. We have found several other rings with similar characteristics without stones in them, or with emeralds, but this is the first ring with an amethyst found on the Atocha site.”

The Fisher family today takes regular groups to dive the Atocha site. For more details, go to http://www.melfisher.com/myadventure/


Police Divers Go Underwater To Find Bodies and Evidence

bilde-300x225 Police Divers Go Underwater To Find Bodies and Evidence

Most scuba divers would stay away from a sinkhole, but for divers at the Polk County Sheriff’s Office and the Lakeland Police Department, a sinkhole might contain the evidence needed to solve a crime.

Sinkholes, phosphate pits, gator-filled lakes - these are just a few of the places professional search and recovery divers are jumping into across Polk County. And all of them are dangerous. So dangerous, in fact, that search and recovery diving is the next installment in The Ledger’s ongoing series, “Out of the Cubicle: Dangerous Jobs in Polk.”

“It’s a series of challenges, from the diving to the environment, you encounter everything from microscopic germs to enemies as large as alligators,” said Brian Hanger, a deputy sheriff in the marine unit for PCSO.

Search and recovery divers often are called to the scene when a crime or accident involves a body of water. They recover evidence to solve crimes, bring a sense of closure to families who have lost loved ones in the water by finding bodies, and rescue fishermen on sinking boats.

Divers with the PCSO have dived about 20 times so far this year, and last year they dived about 80 times. The Lakeland dive team sees a little less action, with only a few dives per year. Each team has about eight divers.

To keep divers safe, each team trains regularly at different locations each time.

“We try to do a variety of things because Polk County has such a variety of lakes and we try to get people, when they are training, to keep in the mind-set that every body of water is different,” Hanger said.

The training is usually more diverse than normal sport dive training and focuses on safety. Training consists of learning how to communicate while under water, mapping out grids to perform evidence searches and learning recovery techniques.

An important part of safety is being able to communicate, Hanger said. Because of low visibility in the water, divers must learn to use different methods of communication, such as underwater headsets, because the normal hand signals most sport divers use cannot always be seen.

“When diving in the Lakeland area, we are lucky to see five or six inches in front of us because the water is so murky,” said Hans Lehman, the dive team supervisor for LPD.

The divers wear dry suits to protect them from exposure to any harmful bacteria or chemicals that may be in the water, especially in sinkholes and phosphate pits, Hanger said.

The extra-thick dry suits also protect the divers from puncture wounds from objects along the lake floors. The divers move slowly while underwater to avoid injury, Lehman said, but many discarded items serve as possible traps.

“Some of these lakes, you never know what you will find in them because people throw all sorts of stuff in there,” Lehman said.

“We have found everything from cups to plates to TVs to tires, refrigerators, engine parts and vehicles,” he said.

Not knowing what is lurking beneath the surface is often the most dangerous part of the job, Hanger said.

While diving in Lake Toho in Osceola County in an attempt to retrieve a firearm used in a crime, Hanger became entangled in fishing lures and lines and was unable to free himself.

But he was able to communicate with the other officers on land through the underwater communication system the dive teams use and they were able to pull him out.

“It took half an hour to cut me out of the fishing lines,” Hanger said.

Divers must also be aware of the wildlife in the water.

Lehman said alligators usually leave the divers alone, but the divers try to avoid night dives because alligators are nocturnal.

“For everybody’s safety, we will usually go in the daytime,” Lehman said.

The focus on safety for both teams has meant few injuries for the divers. In 13 years, Hanger could recall three injuries to divers, most of them minor.

“We’ve been very fortunate, but we’ve been practicing very good safety plans because we understand it is very dangerous and we take it very seriously,” Hanger said.

“As time has gone on we have focused on training, to keep us lucky.”


Divers Recover Ancient Bust of Julius Caeser

Wednesday, October 7th, 2009

article-0-013ae61000000578-367_468x355 Divers Recover Ancient Bust of Julius Caeser

A bust of Julius Caesar found in a trove of Roman artefacts by divers in the River Rhone is the oldest ever discovered, French ministers say.

The life-sized bust showing the Roman ruler with wrinkles and hollows in his face is tentatively dated to 46 BC - just two years before Caesar was assassinated.

Divers, trained in archaeology, uncovered the imperial bust and a collection of other finds in the Rhone near the town of Arles, formally turned into a Roman military colony by Caesar.

“This marble bust of the founder of the Roman city of Arles constitutes the most ancient representation known today of Caesar,” the culture ministry said, adding that it “undoubtedly” dates to the creation of Arles in 46 BC.

Among other items in the treasure trove of ancient objects is a 5ft 11in marble statue of Neptune, dated to about 210 AD.

Two smaller statues were also found, both in bronze and measuring 27.5in. One shows a satyr – a man with goats’ legs considered a symbol of licentious pleasure - with his hands tied behind his back and “doubtless” originates in Hellenic Greece, the culture ministry said.

Of the discoveries “some are unique in Europe”, Culture Minister Christine Albanel said.

Experts are now trying to understand why the treasures were thrown into the river.

The site “has barely been skimmed,” said Michel L’Hour, chief of France’s Department of Subaquatic Archaeological Research, whose divers made the discovery between September and October last year.

A new search operation will begin this summer, he added.

He said the Arles region of Provence, a hotbed of Roman activities, was “propitious” for discoveries.
