Help us to Save our Sharks with your Signature!
With a mouthful of teeth, sharks do not seem to need much protection.
In fact one shark goes through thousands of teeth in a lifetime. Each row of succeeding teeth is larger than the set before.
But sharks´teeth are built for eating. The shape of a sharks teeth depend on the type of food it eats, and some sharks’teeth change shape as they grow older and their diet changes to suit the needs of their growing bodies.
sharks also have other types of protection. A protective lid, called the nictitating lid, helps keep its eyes safe from harm when it attacks prey or nears an unfamiliar object. Some sharks will also roll their eyes back into the sockets showing only the whites while attacking prey to protect the more important seeing part of the eye.
Bottom feeding sharks, such as the angel shark or wobbegong, have coloration matching their environment. Others will bury themselves in the sandy ocean bottom.
However, sharks have little or no protection from humans who hunt them for almost every part of their body to make leather, jewelry, soup, cosmetics, and other items. Sharks are also hunted for sport and many are inadvertently caught in fishing nets or in nets placed to protect humans.
However; the product that drives the market are the fins. After drying, collagen fibers are extracted from them, cleaned, and processed to make ‘shark fin soup’. In spite of the fact that these fibers have little flavour or nutritional value, the soup is considered a delicacy, and may sell in the Orient for more than $100 ( £65) a bowl. As long as the humans pay a lot of money for these fins, it will never stop, and we will kill the sharks and ourselves
The explosive growth of the Chinese economy and rapid expansion of trade with the outside world during the 1985 and 1995 created an unprecedented situation. Suddenly there was an insatiable demand for shark fins of almost any size or type. Improvements in shipbuilding and navigational electronics meant that shark fishing boats could now go anywhere in the world, moving from one place to another as local shark populations were destroyed. The fins are now so much more valuable than the rest of the shark that the carcass is often discarded after the fins are removed, to save storage space on the boat. Often the fins are sliced off when the shark is still alive and the mutilated shark is dumped back into the water, where sinks straight to the bottom because without back fin can´t swim, to die a slow and agonizing death.
Helping To Protect Sharks
Since sharks reproduce at a much slower rate and mature more slowly than bony fish, it is important that people are careful not to deplete the shark population to a point where it can not be recovered. In some cases the environments in which the sharks live are being destroyed.
While sharks have a bad reputation, they rarely attack people unless they are provoked or mistake a human for their normal prey. More people drown in the ocean each year than are attacked by sharks. Only a few of the 365 types of sharks, the bull, the great white, the oceanic white-tip, and the tiger shark are aggressive toward human.
Encouraging the use of electric barriers instead of nets to keep sharks out of an area is one way to help. Also discourage the hunting of sharks for sport or the production of unnecessary articles such as jewelry and souvenirs. In addition learn more about sharks and inform others of ways to live peaceably with these fascinating animals.
A Shark’s Sixth Sense
In order to live and hunt in the ocean waters, sharks have the same 5 senses as human do. They have smell, taste, touch, hearing, and sight. These senses vary in their strength. Many sharks have sharp eyesight, some of which seem particularly sensitive to movement. Most sharks also have a well developed sense of smell.
However, sharks possess a sixth sense which people do not have. Sharks are able to detect weak electrical signals generated by their prey. This sense is detected through small sensory pores called ampullae.
• The smallest shark is the dwarf dog shark which is 6 ½ inches (16 cm) in length.
• The largest shark, ranging up to 40 ft. (12m) in length is the whale shark.
• Whale sharks are large non aggressive creatures which will sometimes allow divers to hitch a ride by holding on to a pectoral fin.
• Most sharks give birth to live young rather than lay eggs.
• The shark with the longest tail is the thresher shark. Its tail can be 5-8 ft. in length, or as long as its body.
• The hammerhead shark swings its head from side to side as it swims, allowing it to use its well developed sense of smell and many ampullae to search for prey in a wide variety of directions in a small amount of time.
• The fastest shark is the Mako, which can swim at 20 mph (32 kph) and leap completely clear of the ocean surface when it is excited.
• Angel sharks have extra large pectoral fins resembling angel wings. These sharks spend their lives mostly on the ocean bed resting in the sand waiting for prey to come to them.
• Some sharks migrate hundreds of miles using what scientists believe to be a sense of the earth’s magnetic field to guide them.
• One shark makes oval shape bites in its victim, by creating a suction with its lips and swiveling around for the bite. It is appropriately named the cookie cutter shark.
• One of the smallest sharks, the lantern shark, grows to only 8 in (20 cm) in length and glows in the dark.
• The most recent discovery of a shark was not made until 1976. This was the large Megamouth shark, of which only five more have ever been found. This unusual shark which feeds on krill has luminous organs around its mouth.

Things worth knowing about Sharks:
“He who fears an animal will only see its threatening behaviour” – this quote from Nobel Prize winner Bertrand Russell seems to capture better than most sentiments the relationship between shark and man. Most people simply know too little about sharks in order to overcome the fear being propagated through the media. Sharks are always depicted as monstrous man-eaters in sensational films and reports. A new image of the animals is only slowly emerging in the media. This “man-eater” is gradually being portrayed as an intelligent predator with more of an aversion to humans. Sharkproject has compiled facts and information on this here in the Shark Compendium.
They will constantly be developing this knowledge library further, adding new research findings and chapters. So it’s worth dropping by at regular intervals!

Haiothek Wissenswertes über Haie
“Wer Angst vor einem Tier hat, wird in dessen Verhalten immer nur das Bedrohliche sehen!” pointierter, als dieser Ausspruch des Nobelpreisträger Bertrand Russel, kann man das Verhältnis zwischen Hai und Mensch nicht beschreiben.
Die meisten Menschen wissen einfach zu wenig über Haie, um die über Medien permanent geschürte Angst zu verlieren. In sensationsgierigen Filmen und Berichten sind Haie immer noch die menschenfressenden Monster. Erst langsam setzt sich ein neues Medienbild der Tiere durch. Aus dem “Menschenfresser” wird so allmählich ein intelligenter und dem Menschen gegenüber eher scheuer Räuber.

Victory in the Southern Ocean Day for the Whales
It’s official – the Japanese whaling fleet has called it quits in the Southern Ocean, at least for this season. And if they return next season, Sea Shepherd Conservation Society will be ready to resume their efforts to obstruct and disable illegal Japanese whaling operations.
“The Nisshin Maru made a significant course change immediately after the Japanese government made it official that the whaling fleet has been recalled,” said Captain Alex Cornelissen from the Bob Barker. “She looks like she’s going home!”
The Sea Shepherd ship Bob Barker has been tailing the Japanese Nisshin Maru factory ship since February 9th making it impossible for the whalers to continue their illegal whaling operations.
“I have a crew of 88 very happy people from 23 different nations including Japan and they are absolutely thrilled that the whalers are heading home and the Southern Ocean Whale Sanctuary is now indeed a real sanctuary,” said Captain Paul Watson.
The Sea Shepherd ships Steve Irwin, Bob Barker, and Gojira will remain in the Southern Ocean to escort the Japanese ships northward. “We will not leave the whale sanctuary until the last whaling ship has departed,” said Gojira captain Locky MacLean.
“This is a great victory for the whales,” said Captain Watson, “but we did not do this alone. Without the support of the people of Australia and New Zealand, we would not have been able to send voyages out for seven seasons from Australian and New Zealand ports. We are grateful to Senator Bob Brown and the Australian Greens Party. We are very grateful to Mr. Bob Barker for giving us the ship that turned the tide in our efforts to force the Japanese fleet from these waters. We are grateful to all our onshore staff and volunteers, supporting members and ship crews. We are grateful to the Chilean Navy and the government of France for their support. It is a very happy day for people everywhere who love whales and our oceans.”
It’s official – the killing of whales in the Southern Ocean Whale Sanctuary is over for this season and the whalers did not even take 10% of their quota. Sea Shepherd estimates that over 900 whales have been saved this year.
“It’s a great day for the whales,” said Sea Shepherd Chief Cook on the Steve Irwin Laura Dakin of Canberra, Australia, “and it’s a great day for humanity!”

Despite many press releases worldwide the Thai Government DOES NOT close all dive sites in the Andaman Sea and the Gulf of Thailand region!
Correct is that a few Dive Sites will be closed due to research. The dive sites which will be closed do not reflect on diving pleasure in Thailand. Please find the links where you can see and find more detailed information that only a few reefs will be closed for scientific research purposes:
Another fact: The coral bleaching comes from to warm water temperatures and not from Divers at all!
Also coral bleaching phenomena is not damaging more than 10% of all corals throughout the Kingdom’s seas, but partly in shallow water areas some of the coral life. You still can enjoy wonderful and colourful reefs in the Andamnan Sea and as well in the Gulf of Thailand!
We awaiting you and looking forward to some amazing dives!

This is the deepest known cave in Thailand and all of it is underwater. It is a very deep vauclusian resurgence with two surface pools which join underwater. The sump contains fresh water, even at -240m. There are several other deep resurgences in this area and the source of the water is not known.
The site was first dived by Matt London and the Thailand Cave Diving Project around 1993. The two surface pools were connected at a depth of 84m. These dives pushed the cave to a depth of -120m using open-circuit equipment. Exploration was resumed in December 2005 when Bruce Konefe, Cedric Verdier and Mike Gadd reached a depth of -150m using rebreathers. In May 2006 Verdier and Gadd extended the cave to -201m. The bottom of the sump was eventually reached by Ben Reymenants in November 2006 at a depth of -240m.
If you do this please ask us first. It is dangerous to dive in caves especially if you go deep! Instructors and divers lost there life in these cave.
But nevertheless there are also many Caves around to reach by foot on land. You’ll need torches to explore these caves and if you like Bats then this is a must! 😉
All can be reached by walking from this lake!

Carlos Coste has created a new Guinness world record for freediving, after swimming 150 metres through a cave using no apparatus.
The Venezuelan was armed with only a torch and a monofin – a single giant flipper worn on both feet – when he made the death-defying dive on Wednesday.
The 34-year-old soared through a passage inside Dos Ojos, a colossal cave network that twists for 31 miles under Yucatan, Mexico.

Record-breaker: Freediver Carlos Coste set a new Guinness world record by swimming 150 metres through a cave while holding his breath and using no breathing apparatus
Caught on camera by British underwater photographer Dan Burton, Mr Coste, from Caracas, has pioneered a new kind of record by taking the world of freediving into the underwater caves.
While only swimming at a depth of around seven metres, the record attempt could have killed the freediver as he swam through the cave while holding his breath.
Becoming trapped in the winding rocky passage could have been fatal.
Beginning at the surface, he dropped into a selected tunnel of the underwater system.
Using special swimming techniques he has honed to perfection over 12 years of freediving, he optimised strength, speed and energy conservation.
He said: ‘I have been doing competitive diving for ten years and this is by far the most bizarre run I have ever made.
Risking his life: Venezuelan Carlos Coste swam through the rocky passage at a depth of seven metres using a technique he has perfected in a dozen years of freediving
‘To achieve this is a dream come true for me. I have been interested in speleology (the study of caves) since I was a little boy and to combine this with my profession as a freediver was amazing.
‘I was not scared about it. We have planned this for a long time and I was fully prepared for what I had to do.
‘If something had gone wrong then there were emergency divers on hand.
‘They didn’t have a spare air supply down there for me. At critical times like that it would simply have been about getting me to the surface as quickly as possible.’
Mr Coste, who can hold his breath for seven minutes, completed his spectacular run in just two minutes and 30 seconds, emerging victorious at the other end of the chosen passage.
Speedy Gonzalez: Carlos Coste completed the run in just two minutes and 30 seconds but he can hold his breath for up to seven minutes
A rope that was laid before he began the attempt showed him the route. But in pitch darkness he needed to hold a torch in one hand so he could see it.
‘It’s not about speed,’ he continued. ‘It’s about striking a balance between many factors.
‘With monofins you can achieve the fastest speeds possible but for something like this you don’t want to be frantically kicking your way through the cave.
‘Inertia, displacement and modality are all massive factors and the optimal technique that has been perfected is to make two kicks, then glide, two kicks, then glide. You need to be in the best hydrodynamic position.
‘It really feels like you are flying through the cave and you have to adopt a position like Superman with your arms stretched out in front of you.
‘The adrenaline brings a massive rush. It makes me feel amazing to be involved in things like this.’
Success: Carlos Coste proudly poses after his death-defying world record attempt – which he has spent three years planning with his wife
Planned meticulously by his wife and manager Gabriela Contreras, 45, the extreme attempt has been three years in the making.
The pair selected the chosen tunnel a year ago and have since been preparing him for the attempt.
‘This hasn’t been done before,’ Mr Coste added. ‘But Guinness said I would need to make at least 75 metres to have a world record.
‘I doubled that so I hope they are satisfied that this should go into the books.’

A third of all animals and plants on earth face extinction — endangered blue whales, coral reefs, and a vast array of other species. The wave of human-driven extinction has reached a rate not seen since the fall of the dinosaurs 65 million years ago.
But there is a plan to save them — a global agreement to create, fund and enforce protected areas covering 20% of our seas and lands by 2020. Right now, 193 governments are meeting in Japan to address this crisis. But without public pressure, they are likely to fall short of the bold action needed to avert the collapse of ecosystems the world over.
This summit ends this week — we have no time to lose. Let’s rapidly build a global public outcry urging governments to save all life on earth from runaway decline. Sign the petition below and it will be delivered directly to the meeting:
To all parties of the Convention on Biodiversity:
One third of Earth’s species face extinction. We call on you to urgently agree to create, execute and fund the protection of 20% of our oceans and lands by 2020. Only bold and immediate action will protect our planet’s rich diversity of life.

Sea Shepherd Unveils Interceptor Vessel to Target Illegal Whaling
At a Hollywood fundraiser on Saturday night, we shared with supporters our desire to add the Ocean Adventurer to our fleet for our upcoming 2010-2011 Antarctic Whale Defense Campaign, Operation No Compromise.
The 12-year-old, 115-foot, stabilized monohull vessel would fill the role of fast interceptor, replacing the Ady Gil, the vessel that the Japanese whaling vessel Shonan Maru No. 2 deliberately rammed and destroyed on January 6th of this year.
This expedition will be our seventh campaign to oppose the illegal activities of the Japanese whaling fleet in the Southern Ocean and we hope it will be our last season. During the past six campaigns, we have saved the lives of nearly 2,000 whales and exposed illegal Japanese whaling activities to the entire world. Last season, we were able to save more whales than the Japanese whalers were able to kill. Five hundred and twenty-eight (528) whales are alive and swimming in the sea because our supporters enabled us to intervene by underwriting our ships and crews.
Each year, because of our supporters, we have become stronger and more effective. Through patience, determination and persistence, we are driving the Japanese whaling fleet into debt and closer to the day they will retreat from the Southern Ocean Whale Sanctuary.
We are confident that with your help, we will see our most effective campaign ever with Operation No Compromise. Our ships, the Steve Irwin and the Bob Barker, are currently being prepared for the campaign. We have recruited the best crew we can assemble. Our only challenge now is to raise the funds for the Ocean Adventurer.
With three ships, we will once again be able to track and intervene against the poachers in the Southern Ocean for the entire season. Our goal is to save more whales this coming season than we did during the last season and to shut down whaling in the Southern Ocean permanently.
Please help us save whales by supporting Operation No Compromise and make a donation today!

OSLO (Reuters) – The world should safeguard coral reefs with networks of small no-fishing zones to confront threats such as climate change, and shift from favoring single, big protected areas, a U.N. study showed.
“People have been creating marine protected areas for decades. Most of them are totally ineffective,” Peter Sale, a leader of the study at the U.N. University’s Institute for Water, Environment and Health, told Reuters.
“You need a network of protected areas that functions well,” he said. “It’s important to get away from single protected areas which has been the common approach.”
Fish and larvae of marine creatures can swim or be carried large distances, even from large protected areas.
That means it is often best to set up a network of small no-fishing zones covering the most vulnerable reefs, with catches allowed in between. Closing big zones can be excessive for conservation and alienate fishermen who then ignore bans.
Reefs from the Pacific Ocean to the Caribbean are nurseries for fish and vital for food supplies since about 40 percent of the world’s population lives within 50 km (30 miles) of the coast.
Climate change, pollution and over-fishing are among threats to reefs. Warmer oceans can damage corals, sometimes irreversibly. The U.N. University study is in a new handbook to help planners cooperate with marine scientists.
On land, planners can usually be confident that plants and animals will stay in areas set aside as national parks, Sale said. At sea, park limits are far less relevant.
In the past, he said, countries had sometimes set up large protected areas for reefs but then cleared mangroves along nearby coastlines to make way for hotels and beaches for scuba-diving tourists. That can damage some fish stocks.
“In the Caribbean, snappers and groupers spend their lives as juveniles in mangroves and sea grass beds,” Sale said. As adults the fish go back to live on the reefs, creating a need for protected zones on both reefs and in mangroves.
Scientists recently discovered that the spiny lobster, the most valuable fishery in the Caribbean, has a larval stage lasting seven months, shorter than widely believed.
Understanding ocean currents can help to show how far they get dispersed within seven months before settling on the seabed. That can also help in deciding where to site protected zones.
Sale said Australia’s Great Barrier Reef was a good example of management, with a network of no-fishing zones and others open to tourism or fishing. That system meant a balance between the needs of people and the reef.

Age before beauty, when it comes to coral? (Image: Naoi/ Flickr/Getty)
JUST 600 meters away from the Great Barrier Reef, the jewel in Australia’s crown, a less spectacular but more ancient reef has been discovered.
The first hint of its existence came in 2007, when seismic and sonar measurements revealed odd ridges and lagoons on the seabed. Confirmation arrived in February this year, when an international team extracted 34 sediment cores from three sites on the seabed, revealing a fossilized coral reef that reaches 110 meters into the sea floor. Preliminary dating of the core indicates that the coral is up to 169,000 years old.
“This is the great-grandmother of the Great Barrier Reef,” says John Pandolfi of the University of Queensland, who was not on the mission. It is “a very important discovery”, he says, and should provide new insights into the genesis of the reef.
The prevailing wisdom has been that the Great Barrier Reef sits atop an older, dead reef, but 110 meters beneath the live reef, the team hit rock. Corals need light to live, and Pandolfi now thinks that when rising sea levels at the end of the last ice age threatened to put the lights out on the ancient reef, some larvae traveled to shallower waters and seeded the modern one.
The findings were presented by Jody Webster of the University of Sydney at the Integrated Ocean Drilling Program conference in Bremen, Germany, in July.

This year TDA presents also additional information on mono fin swimming directly given by the Thai National Coach Mr. Vladimir Karmazin who three times won the World Championships already.
Further information you will find of course on the best diving spots all around Thailand!
Mr. Maik Rudolph, TDA BOD Member, was – as the years before – organizer and leader of TDA booth at TDEX 2010 in Bangkok.
With his idea to present the new discipline of fin swimming beside all information about diving in Thailand he could attract many visitors to the booth!
Therefore especially at the weekend all TDA Team was very busy to provide interesting information to everybody.
For more details on Free- & Apnoe diving click here or contact us directly here!
There were also Environmental Organisations like Greenfins Thai Environmental Reef Check ect. Who showed on how to prevent littering and wasting the Ocean with Movies and little tricks which actually help a lot!
despite huge corruption at whaling commission

A psychic message had gone out to all eco-warriors who had ever fought for whales: “Get your body over to Agadir, Morocco, now!” As we say on the Sea Shepherd and Greenpeace ships, “All hands on deck!”
So there I was at the 62nd Annual Meeting of the International Whaling Commission (June 21-25), walking through loads of security into a room where the fate of the great whales would be decided for one more year. There were 88 representatives from various countries – people who would make the ultimate decisions – and more than 240 non-governmental organizations (NGOs). Everyone was very nervous and there was no clear indication of the fate of the whales, one way or the other. There were powerful forces at play, both good and evil.
Sex was one of the forces working against the whales. Flights, Girls and Cash Buy Japan Whaling Votes read a Sunday Times headline on June 13. A stack of Xeroxed copies of the article sat on the NGO media table and I picked one up. The jokey comments included, “Hookers for harpoons? ‘What do you mean?’ asks the diplomat. ‘You give me harpoons to kill the whales with your vote and I give you hookers, really “good girls” for you. What do you say? We have a deal?’”
It is common knowledge among enviros that a huge block of small nations –surrogates as they are called – have been bought off by the Japanese foreign affairs department and the Sunday Times article provided definitive proof of the corruption. Journalists with hidden cameras and micro-phones had set up a sting operation, posing as anti-whaling lobbyists with very deep pockets, wanting to buy votes.
The Times piece accused Japan of systematically bribing nations with sex, aid, cash and flights in return for their vote to overturn the 1982 ban on commercial whaling and end the hard won Southern Ocean Whale Sanctuary – two huge environmental milestones in the battle to save the last of the whales. The journalists spoke extensively to officials from St. Kitts, Nevis Island, the Republic of the Marshall Islands, Kiribati, Grenada, Ivory Coast, Tanzania and Guinea, offering multi-million pound aid packages if they stopped supporting Japan at the IWC.
For example, within the last two years, Japan had given Tanzania the sum of $88 million pounds (about $160 million Canadian) in fisheries aid. Five Tanzanian government officials at the IWC were given $22,000 pounds for tuition fees and living expenses while they studied in Japan – that’s more than $40,000 Canadian per year times five officials – to get their fisheries degree at a Japanese university.
A Tanzanian official revealed that Japan “secretively” paid for the tickets and hotels for the IWC delegates from different countries. They were also taken on all-expenses-paid visits to Japan where “good girls” would be available.
The Sunday Times reporter asked the Tanzanian official, “So you think the other countries’ representatives are set up with prostitutes from Japan?” The official answered, “Yes, you know, yeah… it starts by… ‘You want massaging? It’s going to be free massaging. Are you lonely? You don’t want any comfort?’”
Both the Associated Press and the Australian Broadcasting Corporation have previously aired stories in which Japanese officials have stated there is nothing wrong with using overseas development aid to buy votes. However, this is the first time prostitution and cash payments have been added to the list of bribes.
I learned the present Chair of the IWC has also received money from the Japanese. The Chair actually confirmed his flights and hotel were paid for by them, yet the NGOs would not call for his resignation. I noted to the NGO that this Chair was obviously in a compromised position and that he controlled the entire conference. When I asked why they would not ask for his resignation, the answer was, “It is better to know the devil you know than to get a new devil that you don’t know.”
After only two hours on Monday morning, the Chair stated, “We are now breaking into secret sessions to discuss the consensus proposal and we will be adjourning to Wednesday morning.”
The consensus proposal called for the approval of commercial whaling in the Southern Ocean Whale Sanctuary and other places at a fixed limit of about 1,300 whales per year for 10 years – a harvest of 13,000 whales. A whaling phase-down would follow, (not a phase-out). In other words, kill whales now for 10 years, in the hope that after 10 years we would start saving whales. Kill whales to save whales, sort of like fighting for peace. All this was happening behind closed doors with media and NGOs waiting for the verdict.
On Wednesday morning, it was clear the “deal” was dead. Chairman Livingstone, in his opening remarks, which reviewed the 10 intercessional meetings held since the Commission met in Alaska three years ago, as well as the work completed over the last two days, quickly revealed that many differences between parties remained unsettled, trade and “scientific” whaling among them. The process had been useful in that exchanges had been cordial and frank, but no consensus had been reached. Japan led off the commentary, saying it was willing to compromise to some extent, but unwilling to commit to zero after 10 years of legal whaling in the Antarctic.
On the edge of the Sahara Desert, the great whales were given one more year of reprieve. Japan is again in the position of violating the ban on commercial whaling and killing whales within the Southern Ocean Whale Sanctuary. The Japanese state they are killing whales for scientific purposes, yet not one peer review scientific paper has been published. Furthermore, they have never answered the question why it is necessary for them to kill whales for research when the world’s scientific community has been employing non-lethal DNA research for more than 20 years.
Despite an international moratorium on commercial whaling established in 1982 and a huge whale sanctuary surrounding Antarctica, roughly 2,000 whales are killed each year, including endangered and vulnerable species. More than 35,000 whales have been killed since the moratorium began.
Australia is preparing its court case against Japan in the International World Court in The Hague, for whaling within a sanctuary and selling their whale meat. If it wins, it will have the moral right to slap tariffs on Japan. Japan may have a bigger navy than Australia, but Japan’s economy is on the ropes; the prime minister likens Japan’s economy to Greece. A trade war would definitely increase the cost to defend Japanese whaling to a $2 billion+ enterprise. Economics will play a significant role in abolishing whaling industry.
I hope the United Nations creates a navy to enforce the many laws in place for the protection of the great oceans. There is also a need to enforce governance issues, such as buying votes. Diplomats should fear jail sentences in cases of bribery. The IWC, in order to maintain credibility with the world, must investigate and take action to stop such blatant usurpation of the Commission’s integrity.
As for the age-old question of whether or not mankind is an instrument for good or evil, a real battle ensued at the IWC and the profoundest changes took place within a short time frame. Yes, we beat back what amounted to a ridiculous proposal to legalize commercial whaling. Meanwhile, more than 20,000 dolphins and porpoises and 2,000 large whales are slaughtered every year. Many other eco-battles lie ahead and I hope that all good people step forward and take an active role in saving our natural world from greed.
Let’s make mankind an instrument for good. There was a real battle here, where profound changes took place within a reduced time frame. Whales are a symbol of life on this planet. If we save the whales we save the humans. Fortunately the good side has won for now. Lets keep it that way. Get involved.

Phuket’s Reefs Gain from Gathering of Experts
Sunday, June 20, 2010
PHUKET’S coral reefs will gain invaluable help this week from 450 experts taking part in the Second Asia Pacific Coral Reef Symposium, over five days on Phuket.
On Tuesday, many of them will dive off the reefs themselves, before returning to talk more about the problems that are assailing coral reefs throughout the region.
Phuket Vice Governor Treerayut Eamtakul said today that with so many difficulties to be surmounted to protect the Andaman’s coral reefs for the future, it was timely and useful to have experts from 35 countries offering up their ideas.
The symposium is being held at Royal Phuket City Hotel until Thursday, with the dive trips and mini-symposiums occupying the experts’ time. ”Phuket will be delighted to hear what these experts can tell us,” the vice governor said.
It’s only the second symposium of its kind – the first was held four years ago in Hong Kong. Associated Professor Put O. Ang jr of the Marine Science Laboratory at the Chinese University of Hong Kong told Phuketwan today that the South China Sea and surrounding area was the richest in the world for coral reefs, marine creatures and plants.
But it was a struggle to ward off destructive fishing methods, sedimentation and deforestation, which were responsible for a general deterioration of the marine environment.
”Eventually this affects the livelihood of people who depend on the reefs,” he said. Bleaching caused by the extra heat of global climate change is the latest challenge. ”If the corals die, the whole system will collapse,” he said.
Dr Thamasak Yeemin, chair of the symposium organising committee and a Professor at Ramkhamhaeng University, said some 40 to 50 percent of Thailand’s coral reefs had been affected by bleaching.
”We can’t control the temperature of the water but we can control the number of divers,” he said. ”Other effects from run-off and fishing can also be managed,” he said.
Quality of the coral reefs was the key, he said. ”The reefs are vital for the tourism industry, on Phuket and around the world,” he added.
Phuket Coral Reefs Still Hostage to Sunshine
Latest Storm clouds have helped to relieve the risk to Phuket’s coral reefs but water temperatures remain high and the region’s natural treasures are not yet safe.

Greenpeace heads to Arctic to investigate urgent ocean threats
We are returning to the Arctic Ocean with our ship the Esperanza this month to reinforce the urgent need to protect one of the most pristine and fragile environments on Earth.
Our ship departs soon from Germany The Esperanza will arrive in the Arctic waters of Svalbard later this month.
The Arctic is warming faster than anywhere else on the planet. As the sea ice vanishes, the fragile marine ecosystem is becoming disrupted and fishing fleets are racing northwards to exploit previously unreachable stocks. At the same time, increasing carbon dioxide levels from fossil fuels and forest destruction are changing the chemistry of our oceans and creating a severe threat to marine life.
The acid test
Our ship, Esperanza, and its crew are joining leading scientists to investigate the change in marine chemistry – called ‘ocean acidification’ as part of our ‘Arctic Under Pressure Expedition’. Although this is a lesser known impact of carbon dioxide (CO2), it has the potential to disrupt our oceans just as much as climate change. The effects of ocean acidification are expected to hit first and hardest in the Arctic, but pose a serious threat to all ocean life, which is already struggling with climate change, over-fishing and pollution.
Each year, our oceans absorb around 8 billion tonnes of the CO2 produced by the use of fossil fuels. The change in ocean chemistry is already evident and causing problems for shell-building sea creatures. But, as the situation worsens, it could cause the breakdown of marine ecosystems and affect the overall ocean health. The survival of corals, plankton and other critical sea life is severely threatened. If CO2 emissions continue to rise at projected rates, there could be a 120 percent increase in ocean acidity by 2060. Ocean chemistry probably hasn’t changed this much, or this quickly, for 21 million years.
In the first experiment of its kind, we are supporting the German marine research institute IFM-GEOMAR (Leibniz Institute of Marine Sciences) to study the effects of ocean acidification on marine ecosystems. The ‘Esperanza’ is taking scientists and over 30 tonnes of scientific equipment, including nine giant marine monitoring systems called ‘mesocosms’, to the Svalbard islands in the Arctic. Scientists from nine countries will be taking part in this research, which is the most comprehensive study on ocean acidification to date. It will highlight yet another scientific reason why we must make deep and urgent cuts in global CO2 emissions.
Thinning ice Prof. Peter Wadhams and his team study Arctic ice thickness in 2009 – with the Greenpeace ship, Arctic Sunrise.
Throughout the northern hemisphere summer, our ‘Arctic Under Pressure Expedition’ will also expose and document the other serious threats to the Arctic Ocean. The melting of sea ice and the expansion of fishing industries into this region are endangering the pristine Arctic environment and unique wildlife. In attempting to secure ‘rights’ to Arctic fisheries, new transport routes, oil, gas and mineral resources, countries gain a vested interest in the continued melting of the Arctic. But, the more coal, oil and gas we burn, the faster the Arctic melts and the closer our planet comes to catastrophic climate change.
Professor Peter Wadhams, head of Cambridge University’s Polar Ocean Physics Group, will join the ‘Esperanza’ in August to investigate the thickness of the ice and its melting rate, following on from his 2009 Arctic work with Greenpeace.
The Arctic Ocean deserves full protection as a marine reserve and we are calling for a moratorium on all industrial activities there – including fishing. In 1991, after a long Greenpeace campaign, the 39 Antarctic Treaty signatories agreed to a 50-year minimum prohibition of all mineral exploitation, in effect preserving the continent for peaceful, scientific purposes. This serves as an example of how Arctic territorial issues should be handled.
The Antarctic is a landmass surrounded by oceans, the Arctic is an ocean surrounded by land, but the polar regions still have a lot in common. Both are incredibly fragile and susceptible to human activities. Both are part of the global commons and should be protected in perpetuity. Both are relatively untouched and should stay that way.
Don’t let it melt away
Quit coal Carbon emissions from coal are destroying polar bear habitat.
We’re also calling on governments to quit coal and spark an energy [r]evolution in order to reduce our carbon dioxide emmissions so that we can avoid the worst effects of climate change and save the Arctic together with all of its amazing wildlife, including polar bears and ringed seals. Governments need to realise the impacts of each new coal fired power plant they approve, and we’ll be in the Arctic for the next three months to show them.
Take Action: Help protect the polar bears — join the call for a global network of marine reserves that includes a fully protected Arctic Ocean

State House and Senate negotiators agreed yesterday to prohibit the possession, sale and distribution of shark fins, a victory for Native Hawaiians, who see the shark as a cultural deity, and for animal rights activists who believe shark finning is a cruel practice that threatens the ocean’s ecosystem.
Restaurants that make shark fin soup would have until July 2011 to use shark fins in their inventory as of this July.
Under the agreement, which now goes before the full House and Senate for final approval, the administrative fine for the first offense would be $5,000 to $15,000; the fine for a second offense would be $15,000 to $35,000 and commercial marine licenses and fishing vessels would be subject to seizure and forfeiture; and the fine for a third offense would be $35,000 to $50,000 and up to a year in jail along with possible seizure and forfeiture of commercial marine licenses and fishing vessels.
The draft also includes an exemption that would allow shark fins to be used for state-permitted research and educational purposes.
Many Native Hawaiians consider sharks ‘aumakua — a protective spirit that can take animal form — and object to the nature of shark finning, which involves cutting the fins from captured sharks and then releasing them back into the water to suffer and die.
Shark finning is illegal in Hawai’i. Animal rights advocates contend that sharks are being harvested around the world for their fins because of the popularity of shark fin soup in Chinese restaurants.
“This is a bill that sets Hawai’i apart,” said state Sen. Clayton Hee, D-23rd (Kāne’ohe, Kahuku), a Senate negotiator, adding that the international community has been watching the bill.
“It is a cultural issue for Native Hawaiians. It is a small acknowledgement of that aspect of the culture,” he said. “It’s something, like other cultural issues, that Hawaiians have been silent about. But they have never, in my opinion, relented on the belief in the ‘aumakua, and the shark is but one of many.”
State Rep. Jon Riki Karamatsu, D-41st (Waipahu, Village Park, Waikele), a House negotiator, said negotiators were looking for a compromise and ended up siding more with environmentalists.
“They can still serve shark fin soup for one more year, basically,” he said of local restaurants.
Inga Gibson, the Hawai’i state director of The Humane Society of the United States, said the bill sets a precedent. She described it as a “wonderful day for Hawai’i’s sharks.”
“Hawai’i has the opportunity to really be the leader in the nation, if not the world, in shark and ocean protection,” she said.
The government stresses that measures resulting from the declaration of the state of emergency in Bangkok and nearby provinces will not affect ordinary people or foreign visitors. But, just to play safe, you can read more information that will help your trip go easier and safer, below.
Prime Minister Abhisit Vejjajiva informed the public of the Thai Cabinet’s decision to declare a severe emergency situation.

Kiwi freediver William Trubridge has set yet another world record by plunging 92 meters underwater.
Trubridge, 29, set the record about 5am New Zealand time in the ”no fins” category of the Vertical Blue 2010 event in the Bahamas.
He held his breath for three minutes and 45 seconds in the record plunge – collecting a tag from a plate 92 meters deep to prove he had set the record.
Before the dive, Trubridge told The Dominion Post the ”no fins” event was the ”purest discipline” in freediving, which required a lot of strength.
”It’s a very physical discipline, because you can only use your hands and feet.”
At the weekend, he attempted to set a world record in a discipline which allows divers to use fins and a rope, but he failed after struggling to ”equalize” one of his ears.
The competition is happening at the 203m-deep Dean’s Blue Hole – the deepest blue hole in the world.
The greatest danger for Trubridge during the dive was that he could run out of oxygen and black out, organizers said.
Trubridge had previously set at least seven world records in the sport, including one in December last year when he dived to 90 meters without fins.
A scientific expedition has discovered the world’s deepest undersea volcanic vents, known as “black smokers”, 3.1 miles (5000 metres) deep in the Cayman Trough in the Caribbean. The team are posting daily updates on their expedition website at http://www.thesearethevoyages.net including photos and videos from their research ship.
Es ist wie eine Achterbahnfahrt: kaum hat mein einen Berg erklommen, geht es wieder mit rasanter Fahrt hinab in die Abgründe. Genauso stellen sich derzeit die Bemühungen dar, eine Katastrophe in den Weltmeeren abzuwenden und endlich, buchstäblich in letzter Minute, den Haibestand zu schützen. Als am 9. März die Malediven sich zum 1. Juli als Haischutzzone erklärten, war ein wichtiges Etappenziel im Haischutz erreicht.
Bis zum 25. März findet in Doha / Katar die 15. Vertragstaatenkonferenz zum Washingtoner Artenschutzübereinkommen (CITES) statt. Und hier gab es gestern eine Schlappe für den internationalen Hai- und Artenschutzschutz, die so nicht eingeplant und erwartet worden war. Sie wird dazu führen, dass die Bemühungen der internationalen Haischutzorganisationen und hunderttausender engagierten Sporttaucher um Jahre zurück geworfen werden! Überraschend verpasste die von der EU und den Vereinigten Staaten unterstützte Initiative nach mehr Transparenz beim Fang und Handel von Haien und Haiprodukten, sowie die Agenda zum Schutz der Blauflossen Thunas die notwendige Zweidrittelmehrheit. China, Japan sowie Russland verweigerten sich dem Haischutzantrag und auch Staaten wie Libyen und Marokko zogen nicht mit, weil sie Probleme für die einheimische Fischindustrie befürchten.
Die internationale Konferenz, an der insgesamt 175 Staaten teilnehmen läuft noch bis zum 25. März. Und auch für den Schutz der drastisch zurückgegangenen Blauflossen-Thunfische hat sich keine Mehrheit gefunden. Japan hat auch in diesem Punkt seine harte Ablehnung signalisiert und hat, u.a. mit der Unterstützung durch China, auch diesen wichtigen Punkt der Agenda zum Flop für den Artenschutz werden lassen.
Mit der Haischutz-Erklärung der Malediven, die bewusst wenige Tage vor Beginn der Konferenz auch ein Zeichen setzen sollte, war zunächst ein leichtes Aufatmen durch die Reihen den engagierten Haischützer und durch die Reihen der Sporttaucher gegangen.
Ibrahim Didi, Fischerei- und Landwirtschaftsminister der Malediven hatte verkündet, dass die Malediven sich nach Palau als zweiter Staat entschlossen haben, ab 1. Juli sein Staatsgebiet zur Haischutzzone zu erklären und jede Form von Haifischerei und -Finning zu untersagen. Neben Palau haben also inzwischen auch die Malediven erkannt, dass mit dem Zusammenbruch der Haibestände nicht nur das gesamte ökologische System in Gefahr gerät, sondern dass die Haie gerade auch für die Attraktivität der Tauchgebiete für Sporttaucher von großer Bedeutung sind. Und für beide Destinationen, Palau und Malediven, sind Sporttaucher eine wichtige Zielgruppe im Tourismusgeschäft.
Leider war die Erkenntnis und das Bekenntnis zum Haischutz auch erst nach jahrelangen, teils massiven Protesten von Haischutzorganisationen mit der Unterstützung hunderttausender Sporttaucher „gereift“. Behilflich war bei diesem Erkenntnisprozess sicherlich auch das Ergebnis der Studie eines Forscherteams der australischen James Cook Universität in Townsville/Queensland, die nicht nur das Great Barrier Reef vor der Haustür hat, sondern auch feststellte, dass rein ökonomisch betrachtet ein grauer Riffhai für die Tourismusindustrie einen Wert von rund 2500 € pro Jahr hat, während ein Fischer für einen zur Strecke gebrachten Hai nur einmalig wenig mehr als 23 € bekommt. Also auch in diesem Fall scheinen ökonomische Kalkulationen und nicht allein menschliche Vernunft das Kernargument für die vernünftige Lösung gewesen zu sein. Doch was nützen zarte Fortschritte wie in Palau und auf den Malediven, wenn sich anderenorts Nationen, wie nun in Katar geschehen, mit Brachialgewalt und unter Missachtung aller Warnungen und wissenschaftlicher Erkenntnisse über ökologische und ethische Erkenntnisse hinwegsetzen und sich als Lobbyisten wirtschaftlicher Interessen bloßstellen. Bleibt zum Abschluss dieser Meldung nur noch ein Zitat von Bertold Brecht anzuhängen:
Sie sägten ab die Äste, auf denen sie saßen
und schrien sich zu ihre Erfahrungen,
wie man schneller sägen könnte, und fuhren
mit Krachen in die Tiefe. Und die ihnen zusahen,

As oxygen-deprived waters increase, they emit more greenhouse gasses into atmosphere
Cambridge, Md. (March 11, 2010) – The increased frequency and intensity of oxygen-deprived “dead zones” along the world’s coasts can negatively impact environmental conditions in far more than just local waters. In the March 12 edition of the journal Science, University of Maryland Center for Environmental Science oceanographer Dr. Lou Codispoti explains that the increased amount of nitrous oxide (N2O) produced in low-oxygen (hypoxic) waters can elevate concentrations in the atmosphere, further exacerbating the impacts of global warming and contributing to ozone “holes” that cause an increase in our exposure to harmful UV radiation.
“As the volume of hypoxic waters move towards the sea surface and expands along our coasts, their ability to produce the greenhouse gas nitrous oxide increases,” explains Dr. Codispoti of the UMCES Horn Point Laboratory. “With low-oxygen waters currently producing about half of the ocean’s net nitrous oxide, we could see an additional significant atmospheric increase if these ‘dead zones’ continue to expand.”
Although present in minute concentrations in Earth’s atmosphere, nitrous oxide is a highly potent greenhouse gas and is becoming a key factor in stratospheric ozone destruction. For the past 400,000 years, changes in atmospheric N2O appear to have roughly paralleled changes in carbon dioxide CO2 and have had modest impacts on climate, but this may change. Just as human activities may be causing an unprecedented rise in the terrestrial N2O sources, marine N2O production may also rise substantially as a result of nutrient pollution, warming waters and ocean acidification. Because the marine environment is a net producer of N2O, much of this production will be lost to the atmosphere, thus further intensifying its climatic impact.
Increased N2O production occurs as dissolved oxygen levels decline. Under well-oxygenated conditions, microbes produce N2O at low rates. But at oxygen concentrations decrease to hypoxic levels, these waters can increase their production of N2O.
N2O production rates are particularly high in shallow suboxic and hypoxic waters because respiration and biological turnover rates are higher near the sunlit waters where phytoplankton produce the fuel for respiration.
When suboxic waters (oxygen essentially absent) occur at depths of less than 300 feet, the combination of high respiration rates, and the peculiarities of a process called denitrification can cause N2O production rates to be 10,000 times higher than the average for the open ocean. The future of marine N2O production depends critically on what will happen to the roughly ten percent of the ocean volume that is hypoxic and suboxic.
“Nitrous oxide data from many coastal zones that contain low oxygen waters are sparse, including Chesapeake Bay,” said Dr. Codispoti. “We should intensify our observations of the relationship between low oxygen concentrations and nitrous oxide in coastal waters.”
The article “Interesting Times for Nitrous Oxide” appears in the March 12, 2010 edition of the journal Science.

Expedition Der Coburger Peter Faltermeier forstet vor der ägyptischen Küste ein Stück Riff wieder auf. Dank eines neuartigen Klebers können sogar abgestorbene Korallen wieder wachsen. Das Pilotprojekt unterstützt unter anderem die LMU München.
Wie das geht? Das Wundermittel sieht aus wie Knetmasse für Kinder, doch in dem blauen und orangefarbenen Kit steckt eine Revolution: „Es gibt bereits Korallenkleber, aber nur fürs Aquarium. Unserer ist fürs Salzwasser und das offene Meer geeignet, er wird nach kurzer Zeit knochenhart und trotzt auch starker Strömung“, erklärt Faltermeier und dreht den Kautschuk zwischen den Fingern. Dann drückt er ihn auf ein Trägermedium, etwa einen Kalkstein, und steckt ein Stück Koralle hinein. Das Besondere: Die Masse, ein Ein-Komponenten-Kleber, ist angereichert mit Spurenelementen. Sobald der Kit geknetet wird, geben in seinem Inneren winzige Kapseln einen Dünger-Cocktail frei. Der ist nicht nur zu 100 Prozent biologisch abbaubar und somit harmlos für Tiere und Pflanzen, er regt das Wachstum der Gewebehaut der Korallen ungemein stark an. Faltermeier und die Entwicklerin des Klebers, die Coburger Ingenieurin Elfi Kummer, haben in Aquarien-Versuchen festgestellt, dass eine damit behandelte Koralle pro Jahr 20 Zentimeter zulegt – in freier Natur wächst sie in diesem Zeitraum gerade mal einen Zentimeter.
Anfang März wird sich Faltermeier auf den Weg nach Ägypten machen – mit 500 Kilogramm des Klebers im Wert von rund 10000 Euro. Eine Abordnung der Ludwig-Maximilian-Universität (LMU) München soll das Projekt begleiten und dabei das Stück Riff vermessen sowie den Grad der Schädigung erfassen. „Die Korallen dort sind noch relativ intakt – und das soll so bleiben. Deswegen gehen wir runter und bessern da aus, wo es schon Löcher und Risse gibt.“ Auch die größte ägyptische Umweltschutzorganisation Hepta hat ihre Unterstützung angekündigt und will das Gebiet während der „Bauarbeiten“ abriegeln.
Das Vorhaben des Coburgers ist so noch nie praktiziert worden. „Ich verspreche mir viel davon“, sagt der 47-Jährige. Wenn der Pilotversuch klappt, dann ließe sich das Aufforstungsprogramm beispielsweise auch vor Sri Lanka anwenden, wo 2006 der verheerende Tsunami auch einen Großteil der Riffe verwüstete. Der Wiederaufbau der Unterwasser-Landschaft wäre eine Sensation – vielleicht gelingt sie mit einem besonderen Klebstoff made in Coburg …
Das anwesende Richterteam habe den Guiness-Rekord bestätigt, schreibt das Tagblatt aus Sankt Gallen, wo Colat sein Tauchvorhaben auf der Ferienmesse öffentlich präsentierte. Um 19 Sekunden hat er damit den bisherigen Eintrag im Guinnessbuch der Rekorde überboten.
Der alte Rekord im sogenannten statischen Zeittauchen mit vorheriger Sauerstoffinhalation wurde vom Italiener Nicola Putignano gehalten. Peter Colat selbst hatte die Bestmarke bereits 2008 gebrochen. Damals schaffte er es, 16:32 Minuten unter Wasser zu bleiben.
Der 38-jährige Colat ist außerdem Schweizer Rekordhalter im Streckentauchen ohne Flossen (127 Meter) und mehrfacher Schweizer Meister in verschiedenen Freitauch-Wettbewerben, wie seiner Website weiter zu entnehmen ist.
Beim Zeittauchen geht es darum, mit einem Atemzug möglichst lange unter Wasser zu bleiben. Gemessen wird die Zeit, in der die Atemwege unter Wasser sind. Beim Zeittauchen mit Sauerstoff atmet der Taucher zehn Minuten vor dem Start ausschließlich 100 Prozent reinen Sauerstoff aus einer Sauerstoffflasche.
