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'...

Recent additions to the premier collection of Southern Ocean sediment cores at Florida State University's Antarctic Marine Geology Research Facility will give international scientists a close-up look at fluctuations that occurred in Antarctica's ice sheet and marine and terrestrial life as the climate cooled considerably between 20 and 14 million years ago.FSU's latest Antarctic sediment core acquisition was extracted from deep beneath the sea floor of Antarctica's western Ross Sea, the...

RV Polarstern finished first Antarctic field season within the International Polar YearThe Antarctic deep sea gets colder, which might stimulate the circulation of the oceanic water masses. This is the first result of the Polarstern expedition of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association that has just ended in Punta Arenas/Chile. At the same time satellite images from the Antarctic summer have shown the largest sea-ice extent on record. In the...

High winds and big waves are part of the data -- and the challengeScientists will embark this week from Punta Arenas, Chile, on the tip of South America, to spend 42 days amid the high winds and waves of the Southern Ocean. Here they hope to make groundbreaking measurements to explain how huge fluxes of climate-affecting gases move between atmosphere and sea, and vice-versa.The cruise, which departs Feb. 28, should provide important information on how the greenhouse gas carbon dioxide moves...

WASHINGTON - More than 30 scientists will embark next week on a research mission to the Southern Ocean. Researchers will battle the elements to study how gases important to climate change move between the atmosphere and the ocean under high winds and seas. NASA, the National Oceanic and Atmospheric Administration (NOAA), and the National Science Foundation are sponsoring the Southern Ocean Gas Exchange Experiment, a six-week research expedition aboard the NOAA ship Ronald H. Brown, departing...

Scientists have discovered giant sea creatures in Antarctic waters while conducting a census of sea life to determine the impact of environmental change.The census, known as the Collaborative East Antarctic Marine Census (CEAMARC), consists of three ships: the Aurora Australis, France's L'Astrolabe and Japan's Umitaka Maru.The expedition to the Southern Ocean took them more than 1,000 meters below the surface to the ocean floor."Gigantism is very common in Antarctic waters -- we have...

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...
