Variations in climate conditions affect reproductive success of Antarctic krill, study finds
climate condition reproduction of krill SAM MEI seasonal variation
2021/8/4
Climate conditions play a significant role in the reproductive success of mature female Antarctic krill and are a factor in fluctuations of the population that occur every five to seven years, a new s...
Antarctic Circumpolar Current flows more rapidly in warm phases
ACC warm phases climate change
2021/8/4
Our planet's strongest ocean current, which circulates around Antarctica, plays a major role in determining the transport of heat, salt and nutrients in the ocean. An international research team led b...

Autonomous multi-drone aerial surveys Antarctic penguin colonies
2020/11/13
Scientist Mac Schwager at Stanford University, an aeronautics and astronautics researcher, learned that biologists were seeking a better way to image a large penguin colony in Antarctica. Schwage...
Fossil evidence of 'hibernation-like' state in 250-million-year-old Antarctic animal（图）
Fossil hibernation-like state 250-million-year-old Antarctic animal
2020/9/4
Hibernation is a familiar feature on Earth today. Many animals -- especially those that live close to or in polar regions -- hibernate to get through tough winter months when food is scarce, temperatu...
Whaling and climate change lead to 100 years of feast or famine for 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...
In 2019, the hole that developed in the ozone layer over Antarctica was the smallest on record since the ozone hole was first discovered, according to scientists at NASA and the US National Ocean...
Study in Antarctic waters reveals why Ross Ice Shelf melts in summer（图）
Antarctic waters reveals Ross Ice Shelf melts summer
2019/10/22
A new paper by NSF-funded researchers at the Earth Institute at Columbia University offers fresh insights into the forces causing the world's largest ice shelf to melt.The Ross Ice Shelf, a part of th...
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...
THE RESEARCH ON ELEVATION CHANGE OF ANTARCTIC ICE SHEET BASED ON CRYOSAT-2 ALIMETER
Antarctic Ice Sheet, Cryosat-2,Satellite Altimetry,DEM, Crossover Adjustment,Kriging Interpolation, Intersection
2018/5/15
In this paper, the Cryosat-2 altimeter data distributed by the ESA, and these data are processed to extract the information of the elevation change of the Antarctic ice sheet from 2010 to 2017. Firstl...
Massive East Antarctic Ice Sheet Has History Of Instability（图）
East Antarctic Ice Sheet History Instability
2017/12/19
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet. It's also thought to be among the most stable, n...
A Series of Fortunate Events:Antarctic Zircons Tell Story of Early Volcanism（图）
Series of Fortunate Events Antarctic Zircons Early Volcanism
2017/12/18
Volcanism is sometimes like food poisoning, where the Earth spews forth unstable material. New research suggests that a significant pulse of volatile carbon was released from the Earth’s mantle around...

Antarctic detector Earth stops high-energy neutrinos their tracks
2017/11/24
An interdisciplinary team of researchers using the IceCube Neutrino Observatory in Antarctica has measured how certain high-energy neutrinos are absorbed by the Earth, as opposed to passing through ma...
