Composition Of Microbial Populations Determined By Freshwater Flows Into The Arctic And Southern Oceans
2012-10-11 08:05:22

Part of NSF's International Polar Year research portfolio, the six-nation study indicates that shallow-water populations have little in common Differing contributions of freshwater from glaciers and streams to the Arctic and Southern oceans appear to be responsible for the fact that the majority of microbial communities that thrive near the surface at the Poles share few common members, according to an international team of researchers, some of whom were supported by the National Science...

Southern Ocean Mechanism Sequesters Carbon Emissions
2012-07-30 15:01:44

Brett Smith for redOrbit.com - Your Universe Online Using a fleet of robotic floats, a team of British and Australian scientists have uncovered the mechanism in the Southern Ocean that sequesters around 40 percent of the world´s carbon emissions. A report on the team´s research, which was published this week in Nature Geoscience, showed that “mixed-layer depth, ocean currents, wind and eddies” create plunging currents that draw atmospheric carbon deep into the...

Penguins Face Population Decline Due To Climate Change
2012-06-21 07:05:11

Lee Rannals for redOrbit.com Penguins in the colder regions of the world are being threatened by man, despite man not actually being present. Two studies have pointed to climate change being the reason for why penguins that frolic in Antarctica are dying off. Scientists from the Woods Hole Oceanographic Institution in Massachusetts believe that there will be an 81 percent reduction in the number of emperor penguins by 2100, bringing the population totals from 3,000 to as low as 500....

Continuing Deep Ocean Change In The Southern Ocean

New research by teams of Australian and US scientists has found there has been a massive reduction in the amount of Antarctic Bottom Water found off the coast of Antarctica. Comparing detailed measurements taken during the Australian Antarctic program's 2012 Southern Ocean marine science voyage to historical data dating back to 1970, scientists estimate there has been as much as a 60 per cent reduction in the volume of Antarctic Bottom Water, the cold dense water that drives global ocean...

Scientists Concerned About Methane, Fishing In Arctic Ocean
2012-04-23 04:04:47

While some scientists encouraged the creation of regulations governing fishing in the Arctic Ocean on Sunday, others published a report warning that the body of water could actually be a significant source of the greenhouse gas methane. The latter team, lead by Eric Kort of the California Institute of Technology (Caltech), participated in a total of five flights to measure atmospheric methane levels in latitudes as high as 82 degrees north in 2009 and 2010, AFP reporters said. They...

MONTREAL, April 22, 2012 /PRNewswire-USNewswire/ -- More than 2,000 scientists from 67 countries urged Arctic leaders, in an open letter released today by the Pew Environment Group, to develop an international fisheries accord that would protect the unregulated waters of the Central Arctic Ocean. New maps show that the loss of permanent sea ice has opened up as much as 40 percent of this pristine region during recent summers, making industrial fishing viable for the first time. "Scientists...

TRAVERSE CITY, Mich., March 15, 2012 /PRNewswire/ -- Bouvetoya Island, which lies in the middle of the Southern Ocean, has been visited by less than 100 people since its discovery, and its 780-meter (2,500-foot) ice-capped volcanic peak had never been conquered by any human being. The expedition team had not only successfully climbed this last unknown remote place on earth, but also planted a capsule on top of it, with strong environmental messages collected from hundreds of people worldwide...

Antarctica Fish Threatened By Climate Change
2012-02-14 04:19:52

A Yale-led study of the evolutionary history of Antarctic fish and their "anti-freeze" proteins illustrates how tens of millions of years ago a lineage of fish adapted to newly formed polar conditions — and how today they are endangered by a rapid rise in ocean temperatures. "A rise of 2 degrees centigrade of water temperature will likely have a devastating impact on this Antarctic fish lineage, which is so well adapted to water at freezing temperatures," said Thomas Near, associate...

Wandering Albatross Alters Its Foraging Due To Climate Change
2012-01-14 03:55:04

Adapting to changing environmental conditions in the Southern Ocean Wandering albatrosses have altered their foraging due to changes in wind fields in the southern hemisphere during the last decades. Since winds have increased in intensity and moved to the south, the flight speed of albatrosses increased and they spend less time foraging. As a consequence, breeding success has improved and birds have gained 1 kilogram. These are the results of the study of an international research team...

Researchers Find New Species Around Antarctic Hot Springs
2012-01-04 10:32:25

Oceanographers exploring some of the most remote deep-sea hot springs have discovered one distinct biological zone teeming with life that nobody ever knew existed. The discovery, located more than a mile down in the ocean just north of Antarctica, uncovered the most strikingly unique array of life forms found in decades, including thousands upon thousands of a particular crab species never seen before, as well new species of barnacle, anemone, snail and starfish. The assembly of living...

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...
