Tiny ocean plankton can reduce global warming by soaking up unexpectedly large amounts of carbon dioxide but their carbon-bloated cells might damage marine food chains, scientists said on Sunday. Experiments in a Norwegian fjord showed that plankton - small drifting plants or creatures - could absorb up to 39 percent of the main greenhouse gas, carbon dioxide, in seawater pens that simulate projected climate conditions to 2150

An upcoming episode (Nov. 14) of History Channel's Monsterquest will supposedly show the largest squid ever caught on video. A squid researcher with film crew in tow filmed a squid estimated to be between 50-100 feet long at 1,000 feet in the Sea of Cortez

Dozens of dead and injured seabirds found coated in black goo are the most visible victims of a 58,000-gallon (220,000-liter) oil spill in the San Francisco Bay that scientists say could threaten wildlife for years. The spill fouled miles of coastline, sending environmentalists scrambling Thursday to save the bay's birds, fish, invertebrates, and marine mammals

Members of the international body responsible for the management of bluefin tuna in the Mediterranean Sea must agree to a moratorium on fishing for this imperilled species or risk the end of a valuable fishery. WWF is calling on the International Commission for the Conservation of Atlantic Tunas (ICCAT) - meeting this week in Antalya, Turkey, from 9 to 18 November - to support a multi-annual closure of the fishery for at least 3 years to give stocks a chance of recovery

Japanese scientists have identified two light receptors in marine algae which appear to be responsible for the proliferation of these plants. The scientists hope to use the findings, published in the Proceedings of the National Academy of Sciences, to control unwanted algal growth, such as red tides, or to cultivate coveted species of kelp that are used as food. In their experiment, the scientists removed the receptors genetically from a species of algae, called vaucheria, and found that the plant could no longer grow even though it was exposed to blue light for the next six months

The President of the Maldives on Wednesday called for urgent global action against climate change, saying rising sea levels are threatening the survival of his country's low-lying islands. Maumoon Abdul Gayoom said 80 of his country's 1 200 islands had experienced tidal surges earlier in 2007, most of which are no more than one metre above sea level. "Never in our documented history have so many islands been affected to such an extent. These surges were a grim reminder of the devastating tsunami of 2004 and a clear warning of future disasters," Gayoom said at a conference on development and climate change in Lisbon

Climate change may get the most publicity, but it's not the only global phenomenon linked to rising levels of carbon dioxide in the atmosphere. Another is the gradual acidification of the oceans, as more of CO2 dissolves in seawater, creating carbonic acid and lowering the pH

THEY may sound like wops, thwops, grunts, moans and squeaks to the human ear, but they could actually be complex conversations between remarkable ocean mammals. Thousands of hours of humpback whale sounds have been recorded off the coast of Queensland and analysed to reveal a secret and ancient language of the deep sea. Over three years, researchers identified at least 34 recurring sounds - some lasting less than one second and others stretching for more than 10 - that can be linked to specific, different social settings
