Underwater Burglar Alarms protect Wrecks


An estimated 1 million ancient shipwrecks litter the seafloor around the globe, proving a tempting target for looters and a nightmare for archaeologists and governments to protect.

But that could be set to change with the advent of a submarine alarm that can identify the telltale sounds of approaching treasure hunters in the hubbub of the oceans.

Recent technological advances have been a boon for underwater research – improvements in GPS navigation, sonar and diving gear mean ancient shipwrecks are more accessible than ever. But archaeologists worry that the same advances will also benefit looters seeking to make a quick profit.

Tuncay Akal of the TÜBİTAK-Marmara Research Center in Kocaeli, Turkey, is a member of an international research team designing an early warning system that can identify plunderers by their acoustic signature and alert officials of their presence.

Bubble detector The sea is a noisy place, with fish, storms and shipping all adding to the cacophony. But Akal says it is possible to pick out looter's noise from the mix by using vector sensors to record the direction of sound waves and identify specific sequences of sounds...[Divemaster News]

North-east firm throws light on ancient shipwreck

A HI-TECH underwater camera designed by an Aberdeenshire firm is being used to examine an ancient Roman shipwreck off Sicily.

Scientists from the marine research group RPM Nautical Foundation have had a major breakthrough thanks to the specialist equipment from Tritech International, based at Westhill, near Aberdeen.

The company, formed nearly 20 years ago, specialises in acoustic sensors and other underwater equipment.

Experts believe the Roman vessel was headed for Italy from north Africa in the 3rd century AD when she foundered in the Egadi Islands off the north-west coast of Sicily.

The wreck is thought to have been a merchant ship carrying foods such as olive oil and grain, with building materials.

It is difficult for divers to access the wreck, which lies in 300ft of water...[The Press and Journal]

Videography students dive to great depths for their best shot

Video technology student Rishane Rajkoomar may never realise his dream of becoming an astronaut, but he has experienced the feeling of floating in space during a novel under-water camera course.

Rajkoomar, 23, was among eight Durban University of Technology (DUT) final-year students chosen to learn marine videography, a component of their BTech degree.

The course — a first for South Africa — is being offered by DUT’s TV school and aims to produce qualified underwater cameramen.

Guided by veteran marine videographer John Du Plessis, students received scuba diving training to enable them to dive up to 12 metres with an instructor.

Initial dives took place in uShaka Marine World’s aquarium. Once competent, students turned their attention to mastering shooting under water...[The Times]

Handicapped, but we can dive


On land, she's unsteady on her feet because of a spinal injury she suffered nine years ago. But in water, Madam Colleen Low, 42, a certified master scuba diver, is a picture of confidence.

Search for the Great Sharks


Dive into a new experience as an aquatic guest

I was kneeling under 12 feet of water when the sensation began, the feeling of something soft and velvety on the back of my neck. A minute passed, then another, and it was still there, a feathery pressure.

There were nine sharks swimming near me, but I wasn't worried about the tickle coming from one of them. They all kept a distance, even if that was barely a foot away at times.

But when I decided to reach back and brush away what I felt on my neck, dive master Yves Delpech, who was behind me, suddenly pushed my hand.

"Didn't want you to put your hand in Gill's mouth," he said after we finished the dive...[StarTribune.com]

12 Questions for the MythBusters on Shark Week's Animatronic Jaws 2.0

If you were caught in the jaws of a great white shark and were being thrashed around in the water, would you be able to poke the shark in its eye—distracting it long enough for you to escape and save yourself from certain death? If you're Adam Savage and Jamie Hyneman of television's MythBusters, there is only one way to find out: Turn a 17-ft.-long fiberglass cast of a great white into an animatronic shark, then put yourself—and a few of your unwitting colleagues—in its jaws. The results of this marine science experiment are featured in a 2-hour Shark Week special, airing this Sunday at 9 pm on the Discovery Channel.

Life clings to the history of Conception Bay

The temperature on my dive computer reads -1C. As I descend down the mooring line, the faint outline of the shipwreck comes into view. It's mid-June and I'm diving on the SS Rose Castle, a 138-metre-long merchant ship sunk in the Second World War off Bell Island, in Newfoundland's Conception Bay, 20 kilometres west of St. John's.

Earl Blundon, my guide from Ocean Quest charters, leads me past soft-coral-draped masts to a pilothouse on the main deck. He shines his light in the open doorway. A rusty fuse box and white transistors dangle from bare metal walls. It's the ship's Marconi Room, where radio operators would have desperately tried to call for help as the German submarine U-518 fired two torpedoes into the Rose Castle's hull on the morning of Nov. 2, 1942.

The ship exploded and sank within minutes, taking down 28 crew. Minutes later, another merchant ship, the PLM 27, was also sunk, taking another 12 lives...[GlobeandMail.com]

Can't decide between cycling and scuba...why not both?

Italy's Vittorio Innocente has set a new world record in underwater cycling, pedalling his specially adapted bike to a depth of 65 metres in the sea near Genoa.

The new mark bettered Innocente's own record of 60m, set three years ago.

The 62-year-old scuba diver was expected to set the record in a televised event on Wednesday but it had to be called off because Innocente damaged an eardrum in his last test on Monday.

But a Guinness Book of Records judge from London authenticated the record on Wednesday after vetting eye witness accounts and checking the computerised depth gauge on Innocente's modified mountain bike.

Innocente said he was sorry he was unable to repeat his Monday feat because of doctor's orders but happy to have taken his mark up a notch.

He thanked a team of local scuba divers who helped him get onto his bike as well as the Carabinieri police who oversaw his effort.

Innocente was lowered into the calm waters of Portofino's maritime reserve at about midday Monday...[ANSA.it]

PhD student to unlock tiger shark secrets with SharkNav

ONE of the most feared creatures of the ocean, the tiger shark, is going to be tracked by satellite navigation thanks to a UQ researcher.

PhD student Bonnie Holmes says her project might unlock some of the many mysteries that remain about the behaviour of tiger sharks and may even prevent future attacks on swimmers.

Although separate studies into tiger sharks have occurred at various places along Australia's eastern seaboard, Ms Holmes is planning to discover details of the creature's migratory and breeding habits through satellite tracking.

Marine biologist Ms Holmes's project has won support from the Queensland Department of Primary Industry and Fisheries and the Wildlife Preservation Society but is looking for corporate support.

Shark tagging stations exist in northern Queensland and New South Wales but they are only monitoring sharks in the immediate area, she says...[CourierMail.co.au]

Grazing sea urchins create ambient underwater noise on rocky reefs

Auckland University researchers say they have discovered why underwater recordings of ambient noise around the nation's coast gets louder twice a day.

Craig Radford and Andrew Jeffs recorded the sounds made by individual reef animals then compared them with the background sound in the natural reef, and found kina was the culprit. The scientists found grazing sea urchins produced the noise as they scraped algae off rocks, New Scientist magazine reported on its website. The bodies of kina act like resonance chambers, amplifying the sound of their chewing, they said.

"When they first come out I guess they're hungry, so they're eating with lots of gusto and making lots of munching noises," Mr Jeffs said.

Ambient noise generated around the coast, especially reefs, is thought to play a role in guiding baby fish and crustaceans which have hatched at sea to suitable habitat in which they can settle.

Researchers have speculated that increased intensity of biologically produced sound during dusk, new moon and summer could enhance the biological signature of a reef and transmit it further offshore. ..[3News.co.nz]

Divers look to solve sunken tanks mystery

A diving club is set to find out whether Second World War tanks found on the seabed are two of only four left in the world.
On Saturday Southsea Sub-Aqua Club will send divers down to take pictures and video footage of what they think are Centaur CS IV tanks.

And during the dive they will also try to work out the mystery of how they were lost, given there is no shipwreck nearby.

The tanks, assigned to the Royal Marines Armoured Support Group, lie eight miles off East Wittering, West Sussex.

They were part of an 80-strong contingent bound for France on D-Day but sank in mysterious circumstances...[The News]

Old quarry to become diving centre

EXCITING plans have emerged to build a specialist scuba diving centre at a disused quarry.
Wath-based Sub Aqua Divers are behind the project, which would involve transforming the former Kilnhurst Quarry site off Wentworth Road.

The proposed centre would be one of only seven in the UK, potentially bringing far-reaching benefits to the Dearne economy.

Mike Atkinson, director of Sub Aqua Divers, said: "Potentially, this could be phenomenal for the area. There are six diving centres like this around the UK and hopefully ours will be another major centre.

"This would be the only centre of its kind in Yorkshire, and Yorkshire is a big place. Everyone would benefit from a centre like this because people who visit will stay in hotels, have a drink in the pubs, use the petrol stations etc so the local economy as a whole benefits."...[SouthYorkshireTimes]

Ibiza wreck open for business

The Don Pedro cargo ship sank in June 2007 when, just ten minutes into its journey, it hit the island of Isla de Daus off the shoreline of Ibiza Town. All of the ship's crew were saved but the vessel was carrying 200 tonnes of oil. As a result three of Ibiza's beaches were temporarily closed and a huge cleanup project ensued.

In May this year the future of the wreck had looked bleak for divers when the Island's Council decided to dismantle the ship. But now, two months on, the council has retracted its original decision and opened the site up to divers.

Classed as a UNESCOTM world heritage site for its Posidonia seagrass habitats the waters of Ibiza already attract a steady stream of divers. However, the opening of the Don Pedro wreck, which is located at a depth of 43m one nautical mile from Ibiza's port, is expected to draw even more to the Spanish island.

Exploration of underwater forest

Underwater archaeologists are taking to Loch Tay to try to uncover more about a submerged prehistoric woodland.

The stumps of about 50 trees were discovered in 2005 - some of them are thought to be about 6,000 years old. The experts are now aiming to find their root system and establish the depth to which the trees are buried.

Meanwhile, a campaign has been launched to help restore the reconstructed crannog, an ancient loch dwelling, which attracts thousands of visitors.

The Scottish Trust for Underwater Archaeology will spend the next two weeks inspecting the drowned forest. They will be focusing on two trees - one dating from 4,270 BC to 4,040 BC and the other dating from 2,350 BC to 2,120 BC. As well as looking for the tree roots, they will be taking samples of the sediment and organic materials to establish if there were any landslips taking place between the Mesolithic and the Bronze Ages..

Israeli Diver Discovers Ancient Amulet at Yavne-Yam


A lifeguard diving at the Yavne-Yam antiquities site next to the Palmach beach unearthed a rare marble discus that was used 2,500 years ago to protect sea-going vessels from the evil eye.

To date, only four such items have been found in the world – two of them here in Israel, one recovered from the Mediterranean Sea off the coast at Carmel in addition to the one at Yavne-Yam.

The ancient white marble discus, which dates back to 4-5 BCE, was discovered by David Shalom, who handed it over to the Israel Antiquities Authority.

According to Kobi Sharvit, the director of the Marine Unit of the Israel Antiquities Authority, “We know from drawings on pottery vessels, pithoi and ancient coins, as well as from historic sources of the fifth century BCE that this model was very common on the bows of ships and was used to protect them from the evil eye and envy, and was meant as a navigation aid and to act as a pair of eyes which looked ahead and warned of danger.

New Coral Reefs Teeming With Marine Life Discovered In Brazil

Scientists have announced the discovery of reef structures they believe doubles the size of the Southern Atlantic Ocean's largest and richest reef system, the Abrolhos Bank, off the southern coast of Brazil's Bahia state. The newly discovered area is also far more abundant in marine life than the previously known Abrolhos reef system, one of the world's most unique and important reefs.

Researchers from Conservation International (CI), Federal University of Espírito Santo and Federal University of Bahia announced their discovery in a paper presented today at the International Coral Reef Symposium in Fort Lauderdale. "We had some clues from local fishermen that other reefs existed, but not at the scale of what we discovered," says Rodrigo de Moura, Conservation International Brazil marine specialist and co-author of the paper. "It is very exciting and highly unusual to discover a reef structure this large and harboring such an abundance of fish," he adds.

The Abrolhos Bank is considered one of the world's most important reefs because it harbors a high number of marine species found only in Brazil including species of soft corals, mollusks and fish found only in the Abrolhos shelf. The Mussismilia coral genus, a relic group remnant of an ancient coral fauna dating back to the Tertiary period that went extinct long ago elsewhere in the Atlantic, is the dominant coral of the Abrolhos reef, which is structured in unique mushroom-like shapes....[Science Daily]

Divers learning more about Lake Erie shipwreck

For more than a century, no one knew exactly where the sidewheel steamer Anthony B. Wayne came to rest.

Now researchers are diving 60 feet below the surface of Lake Erie to explore the wreckage discovered in 2006 and identified last year.

"It's one of the earliest examples of a passenger and cargo steamer that we have, probably one of the oldest in Lake Erie," said Brad Krueger, who is spending the summer learning about the steamer.

Krueger, working on his master's degree in Texas A&M University's Nautical Archaeology program, and two other researchers dive at the site about six miles off the coast of Vermilion nearly everyday.

The passenger vessel went down in 1850 after an explosion, killing up to 80 people. The ship was heading from Sandusky to Buffalo with wine, whiskey and livestock.

Remarkable Underwater Video of China's Great Wall


Every year more than 1.3 million tourists climb the Great Wall of China, but an elite group of divers got a special tour; they viewed the wall through their scuba masks.

While China's "quake lakes" have received considerable attention in recent weeks, few are familiar with the manmade lake around the Great Wall. In the early 1980s, the Chinese government flooded the coastal area of Tianjin in order to form the Pan Jia Kou Reservoir to resolve the region's water shortage. As a result, they also submerged the northern part of the Great Wall, some of which is 65 feet under water.

Will Moss, a diver at Sinoscuba, says the visibility around the Great Wall "is not very good, the reservoir is very cloudy and that means it's hard to be sure of where you are sometimes." At the same time, he also recognizes the unique opportunity he has to see this part of the wall.

"To be able to see and experience a part of it in a way that very few other people get to do - with all the added romance of being under water - I think that's a very special experience," says Moss, "and it's a way to get in touch with history in a way that few people get the opportunity to do."...[CBNnews.com]

Fifty minutes after takeoff, the air base received a radio call from the B-26 saying the crew was bailing out — nothing more.
Search teams found the bodies of Dees and Vail on Nov. 20.

Army Air Forces documents indicate that a futile search for the rest of the crew lasted until Nov. 28.

“We got a telegram saying Bill was missing,” said Abigail Kittiko Casey, Kittiko’s sister. “Then we got telegrams saying they were searching. Then we got a death certificate.”

For almost 50 years, the aircraft lay undisturbed on the sea floor...[Divemaster.com]

Vietravel to hold underwater wedding

VietNamNet Bridge – Tour operator Vietravel will be organizing a mass underwater wedding for four couples on August 8 in Nha Trang City in the coastal province of Khanh Hoa.

Le Hong Viet Thao of the company says that the Oriental philosophy considers that number eight is a lucky one, which could bring good luck and prosperity.

Therefore, organizing the wedding on August 8 will be special and meaningful. The company is also experienced in arranging underwater weddings; last summer, it arranged the first one for an Australian couple in Nha Trang Bay, which earned the company a place in Vietnam Guinness record book as the first company to hold underwater wedding in Vietnam on June 28...[VietNamNet]

Rubber 'snake' could help wave power get a bite of the energy market


A device consisting of a giant rubber tube may hold the key to producing affordable electricity from the energy in sea waves.
Invented in the UK, the 'Anaconda' is a totally innovative wave energy concept. Its ultra-simple design means it would be cheap to manufacture and maintain, enabling it to produce clean electricity at lower cost than other types of wave energy converter. Cost has been a key barrier to deployment of such converters to date.

Named after the snake of the same name because of its long thin shape, the Anaconda is closed at both ends and filled completely with water. It is designed to be anchored just below the sea's surface, with one end facing the oncoming waves.

A wave hitting the end squeezes it and causes a 'bulge wave'* to form inside the tube. As the bulge wave runs through the tube, the initial sea wave that caused it runs along the outside of the tube at the same speed, squeezing the tube more and more and causing the bulge wave to get bigger and bigger. The bulge wave then turns a turbine fitted at the far end of the device and the power produced is fed to shore via a cable...[PHYSORG.com]

New York City subway cars now part of a Virginia reef

MANMADE REEFS designed to attract and hold fish are increasingly popular along the East Coast. From ships intentionally scuttled in the Florida Keys and off North Carolina's Outer Banks to the latest addition--44 stainless steel New York City subway cars added to Virginia's Blackfish Bank Reef--manufactured reefs have been expanding recreational angling opportunities over the past 30 years.

The Virginia Marine Resources Commission sank the donated Metropolitan Transit Authority subway cars from a barge on June 26 just off the coast of Chincoteague in 65 feet of water.

The subway cars were placed in a grid pattern near 50 New York City "Redbird" subway cars sunk in November 2003 and 40 Army-donated surplus armored personnel carriers deployed in 1998, according to the VMRC's John M.R. Bull.

Each car is 50 feet long. The combined weight was 17 tons.

Virginia's marine waters now sport 23 reefs of varying size and composition. Materials such as old concrete pipes, demolished bridges, the remains of piers and a lighthouse or surplus equipment such as subway cars, armored personnel carriers or old Liberty-class ships comprise these underwater housing complexes for marine life...[Fredericksburg.com]

Underwater safari exhibit explores exotic African marine life

Lungfish that breathe oxygen on the ocean surface; catfish that generate bioelectricity to find and zap prey; kaleidoscopic cichlids that incubate eggs in their mouths - these marine creatures are just a handful of rare exotic species on display at the "African Underwater Safari" exhibit at the Maritime Aquarium in Norwalk.

"We're trying to highlight the most interesting aspects of Africa," says Judith Bacal, aquarium exhibit director. "It's an area that is teeming with life."

Visitors are welcomed by the voices of the African Children's Choir of Uganda before coming upon groups of palm trees, boldly colored fish tanks and a pink plastic hippo. Decorative signage leads visitors through a wildlife exploration of the continent's primary bodies of fresh and salt water: the Nile River, Red Sea, rivers of West Africa, the rain forests of Madagascar and the lakes of the Great Rift Valley.

The exhibit also features elephant-nosed fish (which share the same floppy, elongated snout shape as its land-based namesake) and knifefish (which dart forward and backward with equal ease). The timid ground boas and giant day geckos offer a glimpse of reptilian life in the Malagasy rainforest.

"There's a lot of different things for people in this exhibit," says Bacal. "I'm really proud of the variety." ..[Greenwich Time]

Unbelievable visibility creates divers' paradise

Ocean swimmers, free and scuba divers made the most of some the excellent water conditions during the month of June thanks to plenty of east and northeast wind.

In fact, during one time period, around June 16 and 17, divers reporting from the Triangle Wrecks near First Street in Kill Devil Hills said the water was "unbelievably clear" because of the right winds and calm seas.

John Bright, a NAUI instructor out of Outer Banks Dive Center in Nags Head, said he's snorkeled the triangle-shaped wreckage of two ships around 15 times so far this season. Even after conditions stir up the water, it eventually settles out and the "vis gets better," Bright noted.

The depth around the wrecks is about 25 feet and makes for a great place to look at marine life. Bright said it's not uncommon to see triggerfish, little schools of Atlantic spadefish, sheepshead and sea bass...[Outer Banks Sentinel]

'A huge history under that water'

Deep under the rippling waves of the St. Lawrence Seaway sit the remains of villages from half a century ago.

Underwater explorer and filmmaker John Earle calls the submerged land a time capsule -- a mysterious place rich in artifacts that are reminders of an often-forgotten time.

The villages of Aultsville, Dickinson's Landing, Farran's Point, Mille Roches, Moulinette, Wales and the hamlets of Maple Grove, Santa Cruz and Woodlands all existed as places on a map before the 1958 creation of the St. Lawrence Seaway.

Now they exist only in memory -- and under the sometimes murky water of the St. Lawrence River....[OttawaCitizen.com]

Bermuda could be a 'Noah's Ark' for reefs

Bermuda's coral reefs are in such good shape compared to the Caribbean that they could be used as a "Noah's Ark" to re-populate destroyed reefs elsewhere.

That was the positive news from Dr. Thad Murdoch of Bermuda Zoological Society (BZS), who is hosting top scientists to carry out dives to assess the health of local reefs this week.

Bermuda has been chosen as one of nine field trip sites for scientists invited to this month's prestigious International Coral Reef Symposium (ICRS).

Held every four years, the 11th symposium convenes in Fort Lauderdale, Florida, July 7 to 11, as a major scientific conference to provide the latest knowledge about coral reefs worldwide. Leading up to the conference, experts will conduct field trips to several coral reef locations, including Bermuda.

"It's a chance to showcase Bermuda to the international coral reef community," said Dr Murdoch, chief scientist of the Bermuda Reef Ecosystem Assessment & Mapping (BREAM) project, who has spent the past several years conducting the first extensive mapping of Bermuda marine parks and reef areas...[The Royal Gazette]
