Donegal wreck may have Spanish Armada link


TWO SHIPWRECKS discovered off the Donegal coastline may be linked to the late 16th-century Spanish Armada and a separate late 18th-century French armada, despatched to assist Irish rebellion efforts.
However, identification of the two wrecks outside Burtonport harbour may take some time, Connie Kelleher of the Department of Arts, Heritage and the Gaeltacht’s underwater archaeology unit, said yesterday.
The two shipwrecks, one of which is definitely a warship, are lying 200m apart in just four metres of water off Rutland Island close to Burtonport.
Lead shot balls were retrieved during dives in which Ms Kelleher participated yesterday morning. Pottery has also been recovered from within the hull of the possible Spanish Armada ship, which is filled with sediment.
A full excavation of material is under way, as part of a long-term management plan for the location.
Minister for Arts, Heritage and the Gaeltacht Jimmy Deenihan has awarded €50,000 for the work, and the Geological Survey of Ireland’s vessel Keary, named after late geologist Raymond Keary, is providing a support platform for the dive team.
Many of the wrecks already located lie off the north and west coasts, off Inishowen in Co Donegal; Co Sligo; Clare Island, Co Mayo; Co Galway; and Co Clare; and the Blasket Sound in Kerry.
Five of the hulls, or remains of same, have been located off Donegal, and the three wrecks off Streedagh strand in Sligo were the subject of a protracted court action.
The two wrecks now under investigation were originally pinpointed by Donegal divers, including Liam Miller, Oscar Duffy and Michael Early in 2008-2009. At this stage, identification is uncertain, but Ms Kelleher believes they may be “enormously significant”.
The later wreck, possibly French, could be linked to Napper Tandy’s revolutionary efforts. Tandy (1740-1803), who worked with Wolfe Tone in founding the United Irishmen, accepted a French government offer of a corvette, the Anacreon, and sailed from Dunkirk with United Irishmen and arms, arriving on Arranmore island, close to Burtonport, in September 1798.
However, locals were said to be less than supportive of his aims.
Tandy also learned that Gen Humbert’s expedition had been defeated in Mayo. Nevertheless, he took possession of Rutland, hoisted an Irish flag, and issued a proclamation before leaving and sailing north.
The Geological Survey of Ireland, which is mapping Irish inshore areas as part of the national seabed survey Infomar, will use sidescan sonar and magnetometer equipment in the area to check if there are any other ships.
Mr Deenihan said yesterday that he was “delighted” to be able to support investigations into “a major find of significance not only to Ireland, but also to the international archaeological, historical and maritime communities”.
Mr Deenihan said that if one of the wrecks proves to be from the Spanish Armada, it could constitute one of the most intact on this coast to date and could provide “huge insight into life on board and the reality of the military and naval resources available to the armada campaign”.
He paid tribute to the co-operation of the National Monuments Service and the National Museum of Ireland, which will take responsibility for any artefacts recovered.
SPANISH ARMADA
SOME 24 to 26 Spanish Armada ships are believed to have foundered off the Irish coast in 1588 while en route to invade England under the command of King Philip II.
At least 14 of the sunken ships have been extensively mapped to date.
The total armada fleet of 130 ships, with 29,453 sailors and soldiers on board, comprised 65 warships, 25 transport vessels, four galleys and a number of smaller vessels.
When the fleet was defeated in the English Channel, a scattered fleet opted for the Scottish and Irish west coast route home, but ran into storms. “God breathed and England was saved” was Sir Francis Drake’s later remark about the maritime disaster, which resulted in less than 75 per cent of the fleet making it home.


Use seawater or vinegar to treat jellyfish stings, not urine




But according to the British Red Cross, the widespread belief that urine can lessen the pain of venom injected by the marine creatures is misplaced.
It says the substance has the wrong chemical make-up for the job, and that seawater or vinegar is more effective.
The advice comes after conservationists claimed that the number of jellyfish off the coast of Britain is on the rise.
Last month swarms of moon jellyfish led to the closure of a nuclear power plant in Scotland by blocking its cooling water filters.
As families head to the seaside this weekend at the start of the school summer holidays, Joe Mulligan, head of first aid at the British Red Cross, said: “A sting from a jellyfish can be extremely painful, but trying to treat it with urine isn’t going to make your day any better.
“Urine just doesn’t have the right chemical make-up to solve the problem.”
He went on: “If people have been stung, they need to get out of the water to avoid getting stung again. Once out, slowly pouring seawater over the sting will help ease the pain.
“Doing the same thing with vinegar can be even more effective as the acid helps neutralise the jellyfish sting. But, unless you’re near a chip shop, seawater will probably be easier to find.”
Although described by some as an “old wives’ tale”, the belief that urinating on a jellyfish sting will lessen its pain became far more widespread after it featured in an episode of the American sitcom Friends.

Slaughtered for the market place: Huge rise in ray hunting threatens ocean's 'gentle giants'

They are known as the ocean's gentle giants, but an alarming rise in manta and mobula ray hunting could threaten the very existence of the species.

From India to Ecuador, manta and mobula fishing has become big business for fisheries who are selling their gills to be used in soups and traditional Chinese medicine.

Conservationists have warned that demand could soon rival that of the controversial shark fin trade.

The rays are pulled from the ocean, either with fine gill nets or spears, and slaughtered to meet growing demand, mainly from the Chinese market.

Chinese practitioners believe the consumption of gills helps reduce toxins in the blood by purifying and cooling it, reducing body temperature and aiding blood circulation.

A belief that these gills boost the body's immune system, especially when swine and bird flu make daily headlines, has further boosted demand. 
 
One kilogram of gill rakers from a mature Indonesian manta sells for up to $200 in the dried seafood markets of China.
Manta and mobula hunting has become big business because they are easy to catch.

But conservationists are concerned that because of overfishing the rays might be facing extinction before scientists are able to fully uncover all of the mysteries they hold.

End of the line: Fishermen haul a dead giant mobula ray to shore in a remote fishing village in Indonesia. Its gills will be cut off and consumed by those who believe it helps reduce toxins in the blood

A single fishing fleet can easily wipe out a local manta population in weeks or months, with little chance of stocks replenishing given their slow reproduction, limited local populations and lack of migration for some of the species.
Their slow maturation and reproductive cycles have raised serious concerns for the future of these species.

Growing demand for the manta and mobula rays, in part thanks to the loss of regional sharks, has transformed subsistence and localised fishing into a global, commercialised, export operation. 
 
In some fishing villages in Indonesia alone, fishermen are catching more than 2,000 mantas each year.

In the Philippines, reports from the Bohol Sea region - a location where major manta fishing is centred - indicate that mantas are now rare in many places where they were once common. 
 
No international laws and only a handful of national laws exist to prevent ray fishing.

Mantas are only protected in a handful of areas around the world including the Maldives, Hawaii, Ecuador and the Yaeyama Islands, Japan. 
 
The manta ray is the largest of the all the rays.
They can grow up to 25ft across and weigh around 5,100lb.
They are mainly found in tropical waters and feed mostly on plankton, which is filtered into their bodies through their gills as swim.  Perfectly stream-lined for gliding through the water, the manta ray can reach speeds of up to 7mph.
They are often spotted swimming with divers and will sometimes surface alongside boats.

100,000 asking to free Singapore dolphins

More than 100,000 people have petitioned to Resorts World Singapore (RWS) through Change.org to free the 25 dolphins that they are holding in captivity. 




Dolphin activist Barbara Napoles started the petition on Change.org, the world's fastest growing social change platform, bringing the dolphins' plight to the attention of tens of thousands of animal lovers and tourists. 

The dolphins are to become the latest attraction for the resort in Sentosa. 


They were captured in Solomon Islands and are being held in Philippines while the facility is being built in Sentosa. 

Only 25 dolphins of the original 27 have survived in captivity so far Animal Concerns Research and Education Society (ACRES), a Singapore-based animal protection group, has gathered local and international support for the dolphins' freedom with their Save the World's Saddest Dolphins campaign. 

Louis Ng, Executive Director of the Animal Concerns Research and Education Society (ACRES) said: "The public has shown their strong support for the dolphins' release and we are confident that an increasing number of people will sign the petition urging RWS to make a moral and ethical decision to let the dolphins go. 

Two years ago, Resorts World Sentosa responded to public outcry and cancelled plans for a whale shark exhibit.

Oceanic Introduces Industry’s first dedicated BACKUP Dive Computer

DiverWire) One of the first rules of scuba diving is to always be prepared. In many instances, that means have a back-up plan, profile or spare equipment should something unexpectedly go wrong. Ironically, with all of the dive computers and options on the market today, no dive manufacturer has ever introduced a designated BACK-UP dive computer – until now! Oceanic Worldwide is pleased to introduce the B.U.D. (Back Up Device), a simple, yet powerful piece of equipment that provides divers with peace of mind.
The B.U.D., which begins shipping this week, is one of the most eagerly anticipated new products of the year. Small and lightweight, you can clip the B.U.D. to your BCD or put it in your pocket and forget about it – until you need it. What makes the B.U.D. unique is that it features the exclusive Oceanic Dual Algorithm system that allows a diver to “match” their primary computer’s profiles in the event of a problem.
According to Doug Krause, Oceanic Worldwide’s Marketing Manager, “There isn’t anything on the market today that does what the B.U.D. does. Having it as part of your standard equipment can help save a day of diving or even a trip.” Krause explained that many live-aboards and dive resorts offer rental computers to divers. However, should there be a problem with one of them, some operators have a policy of keeping divers out of the water as a safety precaution. Having a back up device could easily help save a day or more of precious dive time on an expensive trip.
Some additional features of the B.U.D. include:
  • Long-Life User Replaceable Battery
  • Adjustable Units of Measure
  • Nitrox to 50%
  • Universal Clip
  • Large, Easy to Read Display
  • Time To Fly / Desaturation
  • Safety Stop Countdown
  • Conservative Factor Setting
The B.U.D. is scheduled to be in dive stores early next week. For more details, visit the Oceanic Worldwide website

Huge Crystal Cave Discovered in Russian Waters

Located near Orda village in Perm region, Ural, Orda Cave is also the biggest underwater gypsum crystal cave in the world and second in Eurasia in terms of volumes of its galleries that stretch up to five kilometers. Famous underwater photographer, journalist and dive-instructor Victor Lyagushkin led the team of cave divers and took stunning images of the cave at less than zero degree temperature.


"There is extremely low water temperature, about 3C and 20C below zero on surface. Under these circumstances shooting became very challenging,"Lyagushkin said.


The location of the cave in Ural region, which is known for rich mineral deposits in Russia, may be linked to the gypsum content in Orda Cave, which has transparent water because of the mineral.


A water wonder, a natural wonder and a natural monument of Russia, Orda Cave has been the focus of cave excursions recently.


Here are a few unique pictures of Orda Cave taken by Victor Lyagushkin during numerous expeditions:

Pacific Island Nations Call For World's Largest Shark Sanctuary; 'Now We Can Have Balance'

An area covering over two million square miles of the western Pacific Ocean, two-thirds of the land area of the United States, is slated to become the world's largest shark sanctuary and the first one ever created through a regional agreement among governments.

Leaders at last week's 15th Micronesian Chief Executive Summit passed a resolution (PDF) to begin the process of creating a regional sanctuary where shark fishing would be prohibited. The agreement, which also authorizes the development of a regional ban on the possession, sale and trade of shark fins, covers the waters of the Federated States of Micronesia and its four member States, The Republic of the Marshall Islands, the Republic of Palau, the Territory of Guam and the Commonwealth of the Northern Marianas Islands.

"We applaud and support the chief executives for protecting the sharks of Micronesia," said Matt Rand, director of Global Shark Conservation for the Pew Environment Group, who has worked with Micronesian leaders this year to develop the resolution and presented at the summit to push for its passage. "Their leadership should serve as a model for other coastal nations to safeguard these important keystone species which are rapidly disappearing from the world's oceans, primarily as a result of the escalating demand for Sharkfins in China and other Asian countries."

The Micronesian resolution is the most recent and largest example to date, of a growing realization that sharks, of which a third of all species are headed towards extinction, are in serious trouble. Last month, the Association of Pacific Island Legislatures (APIL), a body comprised of lawmakers from across the Western and Central Pacific, requested all member nations to "adopt legislation for a unified regional ban prohibiting the possession, selling, offering for sale, trading, or distribution of shark fins, rays, and ray parts."

In June and July, Honduras and the Bahamas joined Palau and the Maldives in creating shark sanctuaries. These nations have come to realize that shark tourism is far more profitable than killing the animals for their fins. One year later, the Marshall Islands instituted a shark fishing moratorium after reports of unregulated activity in its waters.

"The world must rise with us to protect our oceans and our environment," said Johnson Toribiong, President of the Republic of Palau. "That is the moral obligation of this generation for the benefit of the next."  "This is a great accomplishment for all the advocates of global and regional shark conservation," said Benigno Fitial, Governor of the Commonwealth of the Northern Mariana Islands, which along with Guam already has banned trade in shark fins. "The protection of sharks will improve our ecosystem. Now we can have balance."

The Micronesian state of Pohnpei has also taken steps to ban the possession, sale and trade of shark fins within its jurisdiction. "I am very thankful that the region has a common voice on sharks," said John Ehsa, Governor of Pohnpei. "Our State Government has pending legislation to save sharks, and I am in full support." The Pohnpei initiative is modeled after Hawaii's landmark shark fin ban which took effect July 1, 2010. That law, championed by Hawaii State Senator Clayton Hee, prohibits the sale, possession, or distribution of shark fins and fin products.

Senator Hee participated in the Micronesia summit to encourage the chief executives to continue their marine conservation efforts, particularly those focused on the protection of sharks and manta rays. "As native sons of the Pacific, the leaders of Micronesia have taken care of their mother by passing this historic resolution to save sharks," said Senator Hee.
