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...
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...
Changing atmospheric conditions may contribute to stronger ocean wave activity on the Antarctic Peninsula（图）

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...

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 ...

in recent years, mass loss from the Antarctic
ice Sheet has contributed nearly 0.5 mm yr–1
to global mean sea level rise, about one-sixth of
the current rate (church et al., 2011). Around

WeSterN aNtarctic peNiNSula pelagic ecology
2015/7/15
Significant strides in our understanding of the marine pelagic
ecosystem of the Western Antarctic Peninsula (WAP) region have been made over
the past two decades, resulting from research conducted...
Time ravages mountains, as it does people. Sharp features soften, and bodies grow shorter and rounder. But under the right conditions, some mountains refuse to age. In a new study, scientists explain ...
Feeding and overwintering of Antarctic krill across its major habitats: The role of sea ice cover, water depth, and phytoplankton abundance
Antarctic krill Feeding water depth
2014/4/2
Antarctic krill (Euphausia superba) were sampled in contrasting habitats: a seasonally ice-covered deep ocean
(Lazarev Sea), ice-free shelves at their northern range (South Georgia) and the Antarctic...
