A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites according to Dr Mark Trimmer of Queen Mary, University of London. "A third of the 'denitrification' that happens in the world's oceans occurs in the Arabian Sea (an area equivalent to France and Germany combined)" said Dr Trimmer. "Oxygen levels decrease as you go deeper into the sea. At around 130 metres there is what we call an oxygen minimum zone where oxygen is low or non-existent. Bacteria that produce nitrous oxide do well at this depth"

Ocean waves as tall as an eight-story building, once dismissed as maritime folklore, can be studied using waves of light, offering hope of predicting where these monsters may appear, U.S. researchers said on Wednesday. "These giant waves have been featured in many famous literary works from the Odyssey to Robinson Crusoe, but they were just thought to be the subject of myth for a long time," said Daniel Solli of the University of California, Los Angeles, whose study appears in the journal Nature. These rogue or freak waves can appear out of nowhere on an otherwise calm sea. Their extreme height -- reaching some 98 feet tall -- can batter a ship, smashing it to bits. "Even modern ships are not immune to damage from these things," Solli said in a telephone interview

Scientists gathering evidence of ancient ice sheets uncovered a new mystery about what's happening on the Arctic sea floor today. Sonar images revealed that, in some places, ocean currents have driven the mud along the Arctic Ocean bottom into piles, with some "mud waves" nearly 100 feet across

The Hawksbill Sea Turtle, Antigua and Barbuda's national sea creature, has been identified by worldwide marine experts as an "indicator" species to show the effects of climate change. Given the history of killing turtles for food or fun on the island, the Environmental Awareness Group is asking the public to take note of the importance of the animal to the environment. The significance of preserving the Hawksbill turtle population is being highlighted this week during a World Wildlife Fund workshop in Miami held under the title, "Developing an Approach for Adaptation to Climate Change in the Insular Caribbean - the Hawksbill Turtle as an Indicator Species"

The penguin population of Antarctica is under pressure from global warming, according to a WWF report. The report, Antarctic Penguins and Climate Change, shows that the four populations of penguins that breed on the Antarctic continent - Adelie, Emperor, Chinstrap and Gentoo - are under escalating pressure. For some, global warming is taking away precious ground on which penguins raise their young. For others, food has become increasingly scarce because of warming in conjunction with overfishing

The animal rights group People for the Ethical Treatment of Animals (PETA) asked the Department of Tourism on Monday to reconsider its endorsement of the Manila Ocean Park. PETA maintained that marine parks present a distorted view of wildlife. It also urged the public to boycott the facility to show their objection to keeping sea animals in captivity. In a letter to Tourism Secretary Joseph Ace Durano, PETA-Asia Pacific campaigns manager Rochelle Regodon said the only thing marine parks taught people was that "it is acceptable to keep animals in captivity -- bored, restricted, lonely and far from their natural homes"

This morning, in the grey swells of the Southern Ocean, a pirate ship will enter the waters of the Australian Antarctic Territory. It is a black ship, bearing a black pirate flag, the Jolly Roger. For the past five days it has sailed south, so that it can take position and wait for its prey. The prey is expected to arrive on Saturday, the day when Japanese whaling ships, operating under the patronage of the Japanese Government, are scheduled to begin hunting minke whales, humpbacks and fin whales in southern waters. This is an area where Australia has declared an exclusive economic zone extending 200 nautical miles (370 kilometres) from the Antarctic coastline in a large swath of Antarctic waters. This is prime whale territory
