Intensifying winds in the Southern Ocean have had little influence on the strength of the Southern Ocean circulation and therefore its ability to absorb carbon dioxide from the atmosphere, according to a study published yesterday in Nature Geoscience. The Southern Ocean slows the rate of greenhouse warming by removing carbon dioxide from the atmosphere and storing it in the ocean. But previous studies raised the alarm by suggesting the Southern Ocean carbon sink is now 'saturated"˜...

A recent study has found that the Southern Ocean has proved more resilient to global warming than previously thought and remains a major store of mankind's planet-warming carbon dioxide. Oceans act as a brake on climate change by absorbing large portions of the extra CO2 released by mankind through burning fossil fuels or deforestation and experts say the Southern Ocean is the largest of these "carbon sinks." Researchers in the past have suggested the vast ocean between Australia and...

Researchers found many of the world's deep-sea octopuses evolved from a common ancestor that still exists in the icy waters of the Southern Ocean. A project called the, "Census of Marine Life" is trying to map the oceans; it started in 2000 and involves more than 2,000 scientists from 82 nations. The first CoML will be completed in 2010. "We are approaching a picture of the oceans ... from microbes to whales," said Ron O'Dor, co-senior scientist of the census of the 2007-08 findings. The...

A genetic study of a fish that lives in the icy waters off Antarctica sheds light on the adaptations that enable it to survive in one of the harshest environments on the planet. The study, in the Proceedings of the National Academy of Sciences, is the first to search the genome of an Antarctic notothenioid fish for clues to its astounding hardiness. There are eight families of notothenioid fish, and five of them inhabit the Southern Ocean, the frigid sea that encircles the Antarctic...

Experts reported on Friday that the amount of sea ice around Antarctica has grown in recent Septembers in what could be an unusual side-effect of global warming. Since the late 1970s, in the southern hemisphere winter, when emperor penguins huddle together against the biting cold, ice on the sea around Antarctica has been increasing, perhaps because climate change means shifts in winds, sea currents or snowfall. But Arctic sea ice at the other end of the planet is now close to matching a...

By CREAN, Mike From primers to post-graduate students, George Knox taught at every level of formal education in New Zealand. But the University of Canterbury Emeritus Professor of Zoology was most acclaimed for his research. His books, articles and scientific papers contributed significantly to knowledge of marine biology. Friend and colleague Sir Martin Holdgate, a Cambridge University don and former Deputy Secretary in Britain's Department of the Environment, says Knox was "highly...

By RANDOLPH E SCHMID By Randolph E. Schmid The Associated Press WASHINGTON Bitter cold and floating sea ice long frustrated scientists seeking to study the ocean around Antarctica in winter. The solution: Send in the seals. The polar regions are expected to be especially sensitive to climate change, but collecting data has been a problem, especially in the wind-whipped Southern Ocean surrounding Antarctica. So researchers led by Jean-Benoit Charrassin of the National Museum of...

Scientists have been frustrated for years when trying to study the ocean around Antarctica in winter. The bitter cold, floating sea ice, and whipping winds in the Southern Ocean make collecting data a difficult task. Scientists now have a solution: use seals. Researchers led by Jean-Benoit Charrassin of the National Museum of Natural History in Paris recruited help from residents in the Antarctic. Electronic data-collecting equipment was glued to 58 elephant seals in the region.  The...

By Ayash, Tarek Gong, Sunling; Jia, Charles Q ABSTRACT Sea salt aerosols play a dual role in affecting the atmospheric radiative balance. Directly, sea salt particles scatter the incoming solar radiation and absorb the outgoing terrestrial radiation. By acting as cloud condensation nuclei, sea salt aerosols indirectly modulate the atmospheric radiative budget through their effective contribution to cloud formation. Using the Canadian Aerosol Module (CAM)-Canadian Centre for Climate...

While studying eight Macquarie Ridge sea mountains scientists have discovered millions of starfish capturing food.The team of 19 marine scientists spotted the phenomenon while studying the region, which spans 875 miles from south of New Zealand toward Antarctica and is home to several underwater volcanoes.They had expected to discover the affects of global climate change while investigating the Antarctic Circumpolar Current, but the focus of the expedition became the underwater cameras'...

The White-chinned Petrel (Procellaria aequinoctialis), is a large seabird in the family Procellariidae. It ranges around the Southern Ocean as far north as South Australia, Peru and Namibia, and breeds colonially on scattered islands; South Georgia, Prince Edward Islands, Crozet Islands, Kerguelen Islands, Auckland Island, Campbell Island and Antipodes Islands. The diet of the White-chinned Petrel is composed mainly of krill, followed by fish. White-chinned Petrels feed by surface...

The Southern driftfish or ragfish, Icichthys australis, is a medusafish of the genus Icichthys found circumpolar in all southern oceans between latitudes 50° S and 60° S, from the surface down to 1.24 mi (2,000 m). Its length is from 13.78 to 31.50 in (35 to 80 cm). The southern driftfish is similar to the rudderfish, and has soft easily-damaged fins, large eyes, and a small flexible mouth. Its flesh is soft and its bones are weakly ossified, giving rise to its second common name as...

The Wandering Albatross, (Diomedea exulans), is a large seabird from the family Diomedeidae which has a circumpolar range in the Southern Ocean. At breeding time they occupy loose colonies on isolated island groups in the Southern Ocean, such as Crozet Islands, South Georgia, Marion Island, Prince Edward Island, Kerguelen and Macquarie Island. Together with the Tristan, Antipodean and Amsterdam Albatross it forms the Wandering Albatross species complex. The Wandering Albatross has the...
