For Whales, too Every year, humans consume 70 million tons of seafood. Though this is an astonishing volume-one that has aserious impact on ocean populations-it cannot compare to sperm whales which consumer more than 100 million tons of seafood annually. Most of this consists of squid and small fish but-increasingly-plastic trash is making its way into the whales' diet as well.Sperm whales, specifically, have been identified as one of the most intelligent species in the ocean-if not on the planet. They posses the largest brains of any known animal-living or extinct-and use sounds and sonar to communicate with one another,organize into social groups, and evenidentify individuals by name.The cosmopolitan species has found great success and managed to establish itself in all of the world's oceans and many of the major seas. One of the keys to this success is their ability to dive deep below the surface-with some dropping nearly two miles-to find food. Even so, they have not been able to escape the scourge of ocean plastic pollution that has also impacted fish, turtles, and birds.Though hunting of sperm whales has been regulated since just after WWII, threats like pollution continue to threaten the species. The problem with ocean ...

Over the past year he has been following the menace of plastic On Midway atoll in the North Pacific, dozens of young albatross lie dead on the sand, their stomachs filled with cigarette lighters, toy soldiers and other small plastic objects their parents have mistaken for food.That sad and surreal sight, says Hong Kong-based Australian film director Craig Leeson, is one of the manysymptoms of a plague afflicting the world's oceans, food chains and human communities: the onslaught of discarded plastic."Every piece of plastic ever made since the fifties exists in some shape or form on the planet," Leeson told AFP. "We throw plastic into a bin, it's taken away from us and we never see it again -- but it still comes back at us."Over the past year, Leeson has been following the menace of plastic from Sardinia to Canada to the Indian Ocean for a film that aims to combine the art of nature documentary with a campaigning quest.Provisionally called "Away", the film -- backed by David Attenborough and the UK-based Plastic Oceans Foundation -- brings together new research on the spread of plastic with missions by "explorers" such as Ben Fogle to show the diverse effects of ...

IMO-BBC Documentary The award winning IMO-BBC documentary film Invaders from the Sea, which address the core of the invasive species in ships' ballast water problem is now available from IMO's Publications Section. This documentary won the gold award in the category of "Best United Nations Feature" at the 2007's "Stories from the Field", the third annual United Nations Documentary Film Festival, which took place in New York. The film was produced by IMO, the United Nations agency responsible for the safety and security of shipping and the prevention of marine pollution by ships, in co-operation with the BBC and the shipping industry.

Miami prepares to dredge its port to accommodate supersize freighters As Miami prepares to dredge its port to accommodate supersize freighters, environmentalists are making a last-ditch effort to protect threatened coral reefs and acres of sea grass that they say would be destroyed by the expansion. The number of successful piracy attacks on ships off the coast of Somalia and the Gulf of Aden has decreased this year leading to fears that there will be an escalation in violence against seafarers.

Coral disease due to stress response from ocean pollution and climate change In the last 30 years, more than 90 percent of the reef-building coral responsible for maintaining major marine habitats and providing a natural barrier against hurricanes in the Caribbean has disappeared because of a disease of unknown origin.Now a University of Florida geographer and his colleagues applied Geographic Information Systems, known as GIS - as well as software previously used to examine human illness - to show where clusters of diseased coral exist. Their findings, published this month in the journal PLoS One, may help scientists derive better hypotheses to determine what contributes to coral disintegration."What you'll find is that spatial techniques have been used relatively little in the coral research community," said paper co-author Jason Blackburn, a UF professor of geography and member of UF's Emerging Pathogens Institute. "With these methods, we gain a better understanding of the disease's distribution across the reef."Microbiologists and toxicologists often run laboratory tests on small samples of Acropora species of coral to determine the factors that contribute to white-band disease, known as WBD. It's visually identified as a white band moving from the base of the coral up, killing the coral ...

People should view ocean protection as a way of life Alarmed by last year's serious oil leak in the Gulf of Mexico and a leak into the sea of highly radioactive water from Japan's crippled nuclear reactors, some Canadian environmentalists are calling for greater steps to be taken to protect the world's oceans.At an event to promote the upcoming World Ocean Day on Wednesday at Blackie Spit Park in Surrey in Canada's British Columbia, about a dozen open-air tents were set up around the park providing information on marine and bird life, habitat enhancement, water quality, pesticide usage, as well as plant life of the marine variety.The theme of this year's World Oceans Day is "Youth: the next wave of change," with the aim of getting young people to view the protection of the oceans as a way of life.Yvonne Dawydiak, a volunteer coordinator for the Friends of Semiahmoo Bay Society, patrons of an area that is part of the Fraser River Estuary and an important feeding ground for migratory shorebirds, said kids were the best resource for getting the conservation message across."Our oceans are under more and more pressure from development, from pollution, and overfishing, ... and young children ...
