Mixing it, Southern Ocean style
Sea water being churned in the ocean off Antarctica may be having a greater effect on global patterns of ocean movement than previously thought, according to new research reported in this week's edition of the international journal Science (9 January 2004).   view more (2004-01-05)

International meeting on the Southern Ocean
The Role of the Southern Ocean in Global Processes: an Earth System Science Approach - 14-16 July 2003, London Over 80 experts from around the world will meet next week (14-16 July) to discuss the Southern Ocean surrounding Antarctica. It's the first attempt by scientists to take a collective... view more (2003-07-10)

Food shortages threaten Antarctic wildlife
Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are... view more (2004-11-01)

El Nino events affect whale breeding
A thirty-year study by an international team of scientists found a strong relationship between breeding success of whales in the South Atlantic and El Nino in the western Pacific.   view more (2006-01-11)

Antarctic krill provide carbon sink in Southern Ocean
New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth's surface than was previously understood.   view more (2006-02-07)

Geophysical Research Letters European Highlights - 1 August 2001
Highlights 4. Deep water has many sources Hellmer and Beckmann ["The Southern Ocean: A Ventilation Contributor with Multiple Sources"] use a coupled ocean/ice-shelf model to determine the location and rate of Antarctic Bottom Water (AABW) formation. Their results suggest that the Atlantic and... view more (2001-07-16)

New technology reveals seal behavior
New technology has allowed an international team including UK scientists from University of St Andrews and British Antarctic Survey to witness for the first time the behaviour of the southern elephant seal (Mirounga leonina) and how it relates to its physical environment.   view more (2007-08-08)

Short-circuit found in ocean circulation
Scientists have discovered how ocean circulation is working in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week.   view more (2007-05-11)

Southern Ocean could slow global warming
The Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought, according to new research.   view more (2006-12-06)

Southern ocean carbon sink weakened
Scientists have observed the first evidence that the Southern Ocean's ability to absorb the major greenhouse gas, carbon dioxide, has weakened by about 15 per cent per decade since 1981.   view more (2007-05-21)

Climate change signal detected in the Indian Ocean
The signature of climate change over the past 40 years has been identified in temperatures of the Indian Ocean near Australia.   view more (2007-05-31)

NASA co-sponsors ocean voyage to probe climate-relevant gases
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.   view more (2008-02-22)

Discarded human debris threatens global biodiversity
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30... view more (2002-04-23)

Ancient climate secrets raised from ocean depths
Scientists aboard the research vessel, Southern Surveyor, return to Hobart today with a collection of coral samples and photographs taken in the Southern Ocean at greater depths than ever before.   view more (2008-02-04)

Indian eddies supply Atlantic Ocean with warm water
Water from the Indian Ocean does not reach the South Atlantic Ocean continuously, but in separate packages. These are called Agulhas eddies, after the current along the east coast of Southern Africa where they originate from.   view more (2005-10-11)

Salty oceans provide early warning for climate change
Monitoring the saltiness of the ocean water could provide an early indicator of climate change. Significant increases or decreases in salt in key areas could forewarn of climate change in 10 to 20 years time.   view more (2007-06-11)

Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences.   view more (2008-10-06)

Voyage to Southern Ocean aims to study air-sea fluxes of greenhouse gases
Scientists 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... view more (2008-02-27)

Climate kick from the Southern Ocean
This much was already known: in the closing phase of the last ice age the Southern Hemisphere began warming first. As a result, the Antarctic sea ice melted. It was at least a thousand years later - as evidenced by investigations of Greenland ice cores - that the high northern latitudes began to... view more (2003-07-29)

Robot submarine reveals secret stash of key Antarctic food source under sea ice
A robot submarine expedition under the Antarctic sea ice has discovered a major food reserve in the Southern Ocean. The findings, reported this week in SCIENCE, show a dense band of the shrimp-like krill under the ice, five times more concentrated than in open water. The importance of sea ice as a... view more (2002-03-05)

Cold water gets mixed in 'blender' of Scotia Sea
The Scotia Sea, located between the Antarctic and the tip of South America, acts like a 'blender' on the very cold ocean waters that influence global ocean circulation patterns and ultimately climate, according to new research from the University of East Anglia (UEA) and published today (28... view more (2002-02-25)

Call for network to monitor Southern Ocean current
In a commentary published in the journal Science today, Dr John Church of the Antarctic Climate and Ecosystem Cooperative Research Centre and CSIRO, through the Wealth from Oceans Flagship, said a Southern Hemisphere observing network is needed to complement a network of moorings now spanning the... view more (2007-08-20)

Saharan dust storms sustain life in Atlantic Ocean
Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean.   view more (2008-07-21)

Sinking Greenhouse Gases into the Ocean
"Polarstern" begins new iron fertilization experiment On January 21, 2004, the "Polarstern", research vessel of the Alfred-Wegener-Institute of Polar and Marine Research, will leave Cape Town for the third stage of the 21st expedition to Antarctica. Forty-nine scientists from nine countries... view more (2004-01-21)

Antarctic expedition provides new insights into the role of the Southern Ocean for global climate
In the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle.   view more (2008-02-06)
