Antarctic animals are under threat from illegal fishing
Animals in the oceans surrounding Antarctica are under increasing threat. Fishery management organisations and governments need to do more to eliminate illegal fishing and regulate better legal fishing in Southern Ocean and adjacent areas according to Professor John Croxall speaking today (17 Feb) at a special symposium - Conserving Migratory Marine Organisms: Protecting animals with ocean-sized habitats organised by the American Association for the Advancement of Science (AAAS). (2003-02-17)

New research into the way the Antarctic ice sheet adds ice to the ocean reveals that tidal motion influences the flow of the one of the biggest ice streams draining the West Antarctic Ice Sheet. (2006-12-20)

King crabs threaten seafloor life near Antarctica
King crabs and other crushing predators are thought to have been absent from cold Antarctic shelf waters for millions of years. Scientists speculate that the long absence of crushing predators has allowed the evolution of a unique Antarctic seafloor fauna with little resistance to predatory crabs. A recent study indicates that one species of king crab has moved 120 km across the continental shelf in West Antarctica and established a large, reproductive population in the Palmer Deep along the west Antarctic Peninsula. (2011-09-07)

Invading crabs could threaten life in the Antarctic
Life on the Antarctic sea floor is under threat from crabs that could invade the area thanks to favorable conditions as a result of global warming, researchers warn. (2014-10-06)

Human 'footprint' on Antarctica measured for first time
The full extent of the human 'footprint' on Antarctica has been revealed for the first time by new IMAS-led research which used satellite images to measure stations, huts, runways, waste sites and tourist camps at 158 locations. The study, which also included researchers from the Australian Antarctic Division and University of Wollongong, found that more than half of all large ice-free coastal areas of Antarctica have now been disturbed by human activity. (2019-03-04)

AAAS at the BA: Whale food, winners and losers in Antarctica and solar insights
The latest thinking on the chances of extinction for Antarctic animals in seas and lakes, whale food hiding beneath sea ice, and new insights on the Sun's spin are among the hot topics slated for discussion at the 9 September Frontiers of Polar Science panel, organized by the American Association for the Advancement of Science (AAAS), through its journal Science. The panel will take place during the prestigious British Association for the Advancement of Science Annual Meeting. (2002-09-09)

Changes in Antarctic sea ice production due to surrounding ice conditions.
Antarctic sea ice production spanning more than 20 years has been understood through the analysis of satellite observations using specially developed techniques. The results of this analysis revealed that changes to the sea ice production in the Southern Ocean were caused mainly because of surrounding ice shelf and fast ice conditions, rather than by wind, temperature, or other factors. (2016-06-29)

Your own private global warming
Researchers from the British Antarctic Survey subjected species found in Antarctic waters to increasing levels of water temperature to learn how well they would cope with a warmer ocean. The study, to be presented at the Society for Experimental Biology meeting on Tuesday, June 30, shows that several of these species are already living really close to their upper temperature range, and that further increases could easily provoke serious ecological imbalances in this region. (2009-06-30)

Researchers have collected venom from octopuses in Antarctica for the first time, significantly advancing our understanding of the properties of venom as a potential resource for drug-development. They also revealed the existence of four new species of octopus. (2010-07-25)

Atmospheric CO2 concentration at Syowa Station in Antarctica exceeds 400 ppm
At Syowa Station, Antarctica, the atmospheric CO2 concentration exceeded 400 ppm on May 14, 2016, for the first time since observations were initiated there in 1984. The monthly mean CO2 for June 2016 also exceeded 400 ppm. CO2 is one of the most important greenhouse gases, and global warming owing to the increase in atmospheric CO2 has become a serious problem worldwide. Therefore, it is crucial to continue monitoring atmospheric CO2. (2016-10-25)

As ice cover disappears, life in the frigid Antarctic moves fast
It might be cold in the Antarctic, but that doesn't mean that life there necessarily moves slowly. A report appearing in Current Biology, a Cell Press publication, on July 11 reveals the discovery of a surprisingly fast-growing community of glass sponges in an area formerly covered by permanent ice. With the ice at the surface disappearing, those little-known sponges are launching a seafloor takeover. (2013-07-11)

Polarstern's biggest fish catch in 24 years of research in Antarctic waters
Five tons of marbled Antarctic cod (Notothenia rossii), now that was surely a big surprise to scientists and crew alike considering that previous and subsequent hauls barely ever reaped such plentiful harvests. Their shimmering silver and dark blue bodies, which can grow up to 70 cm, were piled on the aft deck of Polarstern. In combination with previous stock assessments, fisheries biologists onboard interpreted the catch as a sampling of a discrete, small-scale aggregation of this fish species (2006-12-26)

A new analysis of weather balloon observations from the last 30 years reveals that the Antarctic has the same 'global warming' signature as that seen across the whole Earth, but is three times larger than that observed globally. The results by scientists from British Antarctic Survey are reported this week in Science. (2006-03-30)

Resolving the paradox of the Antarctic sea ice
While Arctic sea ice has been diminishing in recent decades, the Antarctic sea ice extent has been increasing slightly. Researchers from the Georgia Institute of Technology provide an explanation for the seeming paradox of increasing Antarctic sea ice in a warming climate. (2010-08-16)

Antarctic ice shelf retreats happened before
A study of George VI Ice Shelf on the Antarctic Peninsula is the first to show that this currently 'healthy' ice shelf experienced an extensive retreat about 9500 years ago, more than anything seen in recent years. The retreat coincided with a shift in ocean currents that occurred after a long period of warmth. (2005-02-23)

2015 Antarctic maximum sea ice extent breaks streak of record highs
The sea ice cover of the Southern Ocean reached its yearly maximum extent on Oct. 6. At 7.27 million square miles (18.83 million square kilometers), the new maximum extent falls roughly in the middle of the record of Antarctic maximum extents compiled during the 37 years of satellite measurements -- this year's maximum extent is both the 22nd lowest and the 16th highest.
