Researchers Decipher Climate Paradox From The Miocene

AWI Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have deciphered a supposed climate paradox from the Miocene era by means of complex model simulations. When the Antarctic ice sheet grew to...

Climate Change Slowing Down Deep Ocean Conveyor Belt
2014-03-24 08:42:04

Katherine Unger Baillie, University of Pennsylvania Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe. A new study by the University of Pennsylvania’s Irina Marinov and Raffaele Bernardello and colleagues from McGill University has found that recent climate change may be acting to slow down one of these conveyer belts, with potentially serious consequences for the future of the planet’s climate....

April Flowers for redOrbit.com - Your Universe Online In a region of the Southern Ocean, iron fertilization caused plankton to thrive during the last ice age, according to a new study from Princeton University and the Swiss Federal Institute of Technology in Zurich. The findings, published in Science, confirm a longstanding theory that wind-borne dust carried iron to this region of the Antarctic. This iron dust drove plankton growth and eventually led to the removal of carbon dioxide...

Plankton Make Scents For A Cooler Planet And Seabirds
2014-03-21 08:22:49

University of California, Davis The top predators of the Southern Ocean, far-ranging seabirds, are tied both to the health of the ocean ecosystem and to global climate regulation through a mutual relationship with phytoplankton, according to newly published work from the University of California, Davis. When phytoplankton are eaten by grazing crustaceans called krill, they release a chemical signal that calls in krill-eating birds. At the same time, this chemical signal — dimethyl...

Sea Shepherd, Japanese Whalers Clash For Third Time This Season
2014-03-03 13:43:47

Brett Smith for redOrbit.com - Your Universe Online In what appears to be the result of escalating violence, the anti-whaling activist group Sea Shepherd has claimed that Japanese whalers attacked one of their vessels during a recent clash in the Southern Ocean. According to the environmentalist group, the Japanese ships Yushin Maru and Yushin Maru 3 dragged steel cables across the bow of its vessel the Bob Barker 11 times on Sunday in an attempt to disable the craft. When the Bob...

Earth's Climatic History Was Written In Dust
2014-01-25 05:28:19

April Flowers for redOrbit.com - Your Universe Online Polarstern, a research icebreaker, returned from the South Pacific in 2010 with a scientific treasure. The treasure, described in a recent issue of Science, consisted of ocean sediments from a previously almost unexplored part of the South Polar Sea. To geological history researchers, these inconspicuous mud samples are a valuable archive from which they can reconstruct the climatic history of the polar areas over many years of...

Australia Draws Fire For Sending Plane, Not Ship, To Confront Whalers
2013-12-23 07:12:47

Lawrence LeBlond for redOrbit.com - Your Universe Online As the controversial Japanese whaling season quickly approaches and as the conservationist group Sea Shepherd launches its fleet of vessels to confront whalers head on, Australia announced it would send a plane as well to monitor the situation in the Southern Ocean. However, the country’s Environment Minister, Greg Hunt, is drawing fire from a campaign group for opting to send a plane rather than a ship. The Greens, an...

Ocean Water Vertically Mixes As It Rushes Over Undersea Mountains
2013-09-19 07:58:02

April Flowers for redOrbit.com - Your Universe Online In the ocean near Antarctica, an international research team has solved the mystery of how deep and mid-depth ocean waters are mixed. The study, published in the journal Nature, reveals that sea water mixes dramatically as it rushes over undersea mountains in Drake Passage - the channel between the southern tip of South America and the Antarctic continent. This mixing of oceanic water layers is vital in the regulation of the Earth's...

Phytoplankton In The Southern Ocean
2013-09-19 04:45:00

[ Watch the Video: Phytoplankton Observed By NASA Satellites ] April Flowers for redOrbit.com - Your Universe Online Until now, NASA satellites might have missed as much as 50 percent of the phytoplankton in the Southern Ocean. This would make it far more difficult to estimate the potential carbon capture of this vast area of the sea. A new study from the University of Tasmania's Institute for Marine and Antarctic Studies (IMAS), published in the Journal of Geophysical Research, has...

Southern Ocean Sampling Shows Travels Of Marine Microbes
2013-09-18 12:55:33

University of New South Wales By collecting water samples up to six kilometers below the surface of the Southern Ocean, UNSW researchers have shown for the first time the impact of ocean currents on the distribution and abundance of marine micro-organisms. The sampling was the deepest ever undertaken from the Australian icebreaker, RSV Aurora Australis. Microbes are so tiny they are invisible to the naked eye, but they are vital to sustaining life on earth, producing most of the...

West Antarctica Deglaciation Began Much Earlier Than Thought
2013-08-15 10:21:16

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the deepest ice cores ever drilled in Antarctica is revealing some interesting evidence about the southern continent’s turbulent past and the role Earth’s orbit played in the history of the ice ages. Scientists have known for more than a century that ice ages come and go due to the wobbling of the Earth as it orbits the sun. Increases in the intensity of summer sunlight in the Northern Hemisphere melted the ice sheets...

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...
