Whaling and climate change lead to 100 years of feast or famine for Antarctic penguins
climate change 100 years famine Antarctic penguins
2019/12/6
New NSF-funded research reveals how two penguin species, the gentoo and the chinstrap, have dealt with more than a century of human impacts in Antarctica, and why some species are winners and others a...
Antarctic ice cliffs may not contribute to ice-sheet instability as much as predicted（图）
Antarctic ice cliff contribute ice-sheet instability
2019/11/5
Antarctica's ice sheet spans close to twice the area of the contiguous United States. Its land boundary is buttressed by massive, floating ice shelves extending hundreds of miles out over the frigid w...
Data from robotic drifters explain mysterious holes in Antarctic sea ice（图）
robotic drifters mysterious holes Antarctic sea ice
2019/10/28
Winter ice on the surface of Antarctica's Weddell Sea sometimes has an enormous hole called a polynya. A polynya that appeared in 2016 and 2017 offered a unique opportunity for oceanographers to monit...
Instability in Antarctic ice projected to increase likelihood of worst-case sea level rise（图）
Instability Antarctic ice projected worst-case sea level rise
2019/10/23
Images of vanishing Arctic ice are jarring, but the region’s potential contributions to sea level rise are no match for Antarctica’s. Now, a study says that instability hidden in Antarctic ice increas...
Antarctic researchers from Rice University have discovered one of nature’s supreme ironies: On Earth’s driest, coldest continent, where surface water rarely exists, flowing liquid water below the ice ...
Antarctic Bottom Waters Freshening at Unexpected Rate
Antarctic Bottom Waters Freshening Unexpected Rate
2017/2/16
In the cold depths along the sea floor, Antarctic Bottom Waters are part of a global circulatory system, supplying oxygen-, carbon- and nutrient-rich waters to the world’s oceans. Over the last decade...
Changing atmospheric conditions may contribute to stronger ocean wave activity on the Antarctic Peninsula（图）
Changing atmospheric conditions stronger ocean wave activity Antarctic Peninsula
2017/2/16
Over the past few years, a large fracture has grown across a large floating ice shelf on the Antarctic Peninsula. The world is watching the ice shelf, now poised to break off an iceberg the size of De...
NSF,U.K. jointly support research into fate of massive Antarctic glacier
NSF U.K. massive Antarctic glacier
2016/11/4
The National Science Foundation (NSF) and the U.K. Natural Environment Research Council (NERC) have announced that they will jointly fund as much as $25 million in research, and make available additio...
Stanford researchers find that the future of Antarctic marine protected areas is at risk
Stanford researchers Antarctic marine protected areas at risk
2016/11/4
Antarctica’s surrounding waters are home to some of the healthiest marine ecosystems on Earth and support thriving populations of krill, seabirds, fish and whales. But efforts to establish a network o...
Expanding Antarctic sea ice linked to natural variability（图）
Antarctic sea ice natural variability
2016/7/15
The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation, according to a new study led by ...
Sea-level rise from Antarctic ice sheet could double
Sea-level rise Antarctic ice sheet double
2016/4/13
An ice sheet model that includes previously underappreciated processes indicates that sea level may rise almost 50 feet by 2500 due to Antarctic ice sheet melting if greenhouse gas emissions continue ...
Are Antarctic minke whales unusually abundant because of 20th century whaling?

Severe declines in megafauna worldwide illuminate the role of top predators in
ecosystem structure. In the Antarctic, the Krill Surplus Hypothesis posits that the killing
of more than 2 million larg...
Warming Antarctic waters may allow king crabs to "restructure" ecosystems
Warming Antarctic waters king crabs restructure ecosystems
2015/10/13
Rapid warming of the ocean west of the Antarctic Peninsula--the part of the continent that extends north toward South America--makes it possible king crab populations could return from the deep sea to...
A revised precautionary catch limit for Antarctic krill (Euphausia superba) in the Scotia Sea of 4 million tons was recently adopted by the Commission for the Conservation of Antarctic Marine Living R...
Cdrake: dynamics and transport of the Antarctic circumpolar current in drake passage
Antarctic circumpolar current dynamics and transport
2015/7/15
The Southern Ocean is especially sensitive to climate change, responding to
winds that have increased over the past 30 years (Thompson and Solomon,
2002) and warming at about one degree per centur...
