Family of shark victim: ‘He died doing what he liked’

Family of shark victim: ‘He died doing what he liked’
By Angelica Martinez
UNION-TRIBUNE BREAKING NEWS TEAM
April 27, 2008
SOLANA BEACH – The family of the retired veterinarian killed in a shark attack spoke publicly for the first time at a news conference Sunday.
Jeff Martin said his father, David, “died doing what he liked, surrounded by friends, in a place he loved. Even through our grief, this gives us an inner peace.”
David Martin, 66, a longtime Solana Beach resident, was killed shortly after 7 a.m. Friday in Fletcher Cove while taking a training swim with eight members of the Triathlon Club of San Diego.
The county Medical Examiner’s Office conducted an autopsy Saturday and determined that Martin died from blood loss due to shark bites on his legs.
The wounds indicate it was a 12- to 16-foot great white shark, said Ralph Collier, a shark expert with the Los Angeles-based Shark Research Committee, who was present during the autopsy.
Solana Beach Lifeguard Captain Craig Miller said the attack “has affected the beach population immensely.” Typically, on a hot day, lifeguards would see thousands of people swimming, Miller said.
Sunday, there were a few dozen, most of whom heeded the warning and stayed out of the water. Because it was an advisory, lifeguards said they could not stop anyone from entering the water.
On Saturday, dozens of surfers ignored the warning and went in. Among them was Jeff Martin.
Nearly all white shark attacks on humans are “cases of mistaken identity,” said Richard Rosenblatt, a professor emeritus of marine biology at the Scripps Institute of Oceanography in La Jolla. White sharks prefer the blubbery flesh of marine mammals. Martin was wearing a full, black wet suit.
Martin had deep, jagged lacerations from his upper thighs to the lower shins, with a bite radius of about 22 inches.
The last fatal shark attack in California, according to data from the state Department of Fish and Game, took place Aug. 15, 2004, off Mendocino County. The victim was a man diving for shellfish with a friend.
Overall, shark attacks are extremely rare. There were 71 reported worldwide last year, up from 63 in 2006. [+]

Foca-Monge: Last Call for the Mediterranean Monk Sea
2,500 years ago, the monk seal (Monachus monachus) was a common sight in the Mediterranean Sea, loved by the ancient Greeks. Nowadays, it is the rarest marine mammal in Europe and one of the six most threatened animals on Earth.
Despite being listed as critically endangered under the CITES Convention on International Trade in Endangered Species of Wild Fauna and Flora (Appendix I) and the World Conservation Union (IUCN) classification (Red List), as well as classified in need of strict protection under EU law, the monk seal remains the most endangered marine mammal in Europe.
From historically large populations of thousands of animals, the current population is estimated at fewer than 600 individuals spread over Mediterranean and West African countries, around half of which live and breed in Greek waters.
Its genetic group includes 3 species: the Mediterranean monk seal (Monachus monachus) and the Hawaiian monk seal (Monachus schauinslandi) – estimated as endangered – as well as the Caribbean monk seal (Monachus tropicalis), which has been extinct since 1952.
Monk seals are timid animals and very vulnerable to any form of human disturbance. By the end of the 1900s, the Mediterranean monk seal population had declined dramatically due to increasing human impacts such as excessive hunting, habitat destruction, marine pollution, disturbance by tourists, depletion of fish stocks, and competition with local traditional fishermen.

Entre os mamíferos marinhos da Madeira, destaca-se a presença do Lobo Marinho ou Foca Monge (Monachus monachus). Esta é uma das mais raras espécies de foca, existindo a nível mundial menos de 400 indivíduos, distribuídos pela bacia do Mediterrâneo e costas de África. Na Madeira são conhecidos pouco mais de 25 indivíduos que ocorrem essencialmente nas Ilhas Desertas, mas também na Ponta de S. Lourenço e esporadicamente no Ilhéu da Rocha do Navio.No Auditório Darwin conta-se vida e a história do lobo marinho Funchalinho, num vídeo inédito de animação em três dimensões.
Europe plans massive protest against seal hunt
Demonstrations to demand ban on Canadian products
GLORIA GALLOWAY
OTTAWA — Animal welfare activists will stage demonstrations across Europe tomorrow to put pressure on the European Environment Commissioner to ban the import of Canadian seal products.
“Animal welfare organizations all over Europe are going to have a simultaneous press events,” Steven Blaakman, a spokesman for the Eurogroup for Animals, said in a telephone interview from Brussels yesterday.
The groups have been armed with fresh footage of the seal hunt that is continuing, albeit slowly, on Canada’s East Coast. The videos were obtained over the past weeks by the International Fund for Animal Welfare and the Human Society International.
“Animal welfare organizations are going to use the new footage, new images of this month’s hunt to show that it can never be done humanely,” Mr. Blaakman said. “Even if you ban the axe, even if you use rifles, it still can’t be done humanely.”
Stavros Dimas, the EU environment chief, has said that he would ban the import of all seal products from culls in which animals suffer.
Belgium and the Netherlands have already banned the products but a market remains in other European countries.
Mr. Blaakman said tomorrow’s demonstrations are meant to push Mr. Dimas to act.
“Obviously images always work very strongly. And we just want to show people what actually happens,” he said.
“The Canadian traders say ‘oh, it is being done humanely, there are new rules, there is talk over abolishing the axe.’ Even with rifles, it’s difficult to kill them instantly. They still suffer. And I think if people saw it they would agree with us as well.”
But Loyola Sullivan, Canada’s ambassador for fisheries conservation, said the images are deceptive and misleading – especially those that suggests seals are being skinned alive.
Seals have a strong swimming reflex and, for as much as 45 seconds after they are dead, their body continues to make those types of motions, Mr. Sullivan said.
There may be instances where seals are killed inhumanely, he said, but they are isolated and they should be reported to the federal Fisheries Department.
Studies also show that only 95 per cent of cattle are killed with the first blow, Mr. Sullivan said, and the rate is much less for hunted animals such as deer and waterfowl.
“So if we are going to apply isolated cases there, I think you’d better be prepared to stack up to the killing of every animal in the world, whether in the wild or domesticated,” he said.
Mr. Sullivan said he has met with the most senior officials of the European Commission to try to prevent the ban from being imposed.
“We’ve had 11 different meetings with members of the European Parliament to give them the facts in this case,” he said, “because this is an issue that is totally misrepresented, taking isolated incidents and trying to tell people around the world that it’s what’s happening in all the cases.[+]

Egyptian official: speedboat kills 2 Polish divers at Red Sea resort
Egyptian official: speedboat kills 2 Polish divers at Red Sea resort
CAIRO, Egypt: An Egyptian medical official says two Polish scuba divers were killed when they were hit by a speedboat in the Red Sea resort city of Sharm el-Sheik.
The official at the Sharm el-Sheik hospital, Ibrahim Hassan Ali, says the bodies of a Polish man and a woman were brought to the hospital. He says the Polish embassy in Cairo will be notified of the Friday deaths.
Hospital authorities identified the Polish victims as Jona Kosic, 45, a man, and Wizo Kosic, 43, a woman.
Fatal scuba diving accidents happen occasionally in the Red Sea, where thousands of foreigners come annually to scuba dive because of the water’s famous coral reefs.

Ocean Facts: Nutrient-Rich Upwellings | Upwelling(?*)/Afloramento(?*)
When organisms in the sea die they sink, taking their nutrients to the depths. The nutrients don’t stay lost at the bottom for ever though, otherwise there would be very few animals in the surface layer. In polar and temperate oceans, as the surface water gets cold it sinks and forces the nutrient-rich water up from the depths. This process is called overturn. Storms also mix up the layers and this constant churning process is why the waters around the poles are such rich feeding grounds. This is also why the temperature at the poles is so crucial because if the surface water warms up, this massive food factory is effectively shut down. In tropical and subtropical oceans, the surface water never gets cold enough to sink. Here nutrients are provided by upwellings. This is where the wind causes water to move, and the gap left is filled by nutrient-rich water flowing upward from the deep. Regions of upwelling can support large populations of fish. In waters of the coast of Peru an upwelling results in huge numbers of anchovy. Towards the end of the year the winds die down, the upwelling decreases and the water warms up. This is called En Nino. In some years the warm, nutrient-poor waters flow back east and the anchovy disappear, causing knock-on effects for many other species. The nutrients that arise from the deep encourage seaweed growth and support blooms of phytoplankton. This forms food for animals higher in the food chain: fish, marine mammals and seabirds. This can make for good dive sites: other upwelling regions include the Galapagos and Western Australia.

Upwelling(?*)
PT explanation
Upwelling (ou afloramento) e Corrente Costeira de Portugal
O fenómeno do upwelling (ou afloramento) costeiro e a Corrente Costeira de Portugal ocorrem ao largo da costa ocidental Portuguesa durante os meses de Verão (Julho, Agosto, Setembro). Ambos estão associados à divergência junto à costa provocada pelos ventos do quadrante norte que predominam nessa altura do ano. [+]

Eng Explanation the transport of deeper water to shallow levels
One oceanic process altered during an El Niño year is upwelling, which is the rising of deeper colder water to shallower depths. The diagram below shows how upwelling occurs along the coast of Peru. Because of the frictional stresses that exist between ocean layers, surface water is transported at a 90 degree angle to the left of the winds in the southern hemisphere, 90 degrees to the right of the winds in the northern hemisphere. This is why winds blowing northward parallel to the coastline of Peru “drag” surface water westward away from shore. [+]

Arctic marine mammals on thin ice
From: Ecological Society of America
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them. The assessment reflects the latest thinking of experts representing multiple scientific disciplines.
Sea ice is the common habitat feature uniting these unique and diverse Arctic inhabitants. Sea ice serves as a platform for resting and reproduction, influences the distribution of food sources, and provides a refuge from predators. The loss of sea ice poses a particularly severe threat to Arctic species, such as the hooded seal, whose natural history is closely tied to, and depends on, sea ice.
The Arctic undergoes dramatic seasonal transformation. Arctic marine mammals appear to be well adapted to the extremes and variability of this environment, having survived past periods of extended warming and cooling.
“However, the rate and scale of current climate change are expected to distinguish current circumstances from those of the past several millennia. These new conditions present unique challenges to the well-being of Arctic marine mammals,” says Sue Moore (NOAA/Alaska Fisheries Science Center).[+]

Para o próximo fim de semana gostariamos de poder sair, e/ou acabar os cursos, mas vai ser difícil, esperemos por amanhã ou sexta, porque o mar vai baixar, mas será que trás força? pouca visibilidade terá, vamos analisar… pode ser que se possa fazer algum mergulho mais dificil na zona de Peniche.
Ontem tivemos mais 23 jovens de Coimbra do Colégio da Imaculada Conceição, para um baptismo de mergulho em piscina, que sairam entusiasmados, dada a facilidade encontrada, que se tornem “mergulhadores”… Provávelmente, de 17 a 25 de Maio vamos estar na Graciosa para mais um curso de mergulho “Open Water” onde devemos ver em primeira mão (a receber a 8 de Maio) o também novo barco do Centro Náutico da Graciosa, que poderá transportar mais de 20 mergulhadores. Quem está preso ao trabalho no verão, agora também é uma boa altura para mergulhar nos Açores, são ilhas, não está bom num lado estará no outro, e quando eles dizem que está má visibilidade, é entre 18/20 metros; esquisito… Luciano Mesquita – PADI IDC Staff Instructor #939690
