Sea ice oxygen reaching deep ocean during ice age
2021/3/5
Extensive sea ice covered the world's oceans during the last ice age, preventing oxygen from penetrating into deep ocean waters and complicating the relationship between oxygen and carbon, a new study...

Researchers at the University of Maryland, Baltimore County have developed a technique for quicker analysis of extensive data from Arctic ice sheets to gain knowledge of patterns and trends.Over the y...
Greenland is on track to lose ice faster this century than in any other over the past 12,000 years（图）
Greenland lose ice faster century past 12,000 years

Liquid meltwater can sometimes flow deep below the Greenland Ice Sheet in winter, not just in summer, according to National Science Foundation-funded research published in the American Geophysica...
Reframing the dangers Antarctica's meltwater ponds pose to ice shelves and sea level
dangers Antarctica meltwater ponds pose ice shelves sea level
2019/11/15
Dangers to ancient Antarctic ice portend a future of rapidly rising seas, but a new study, partially funded by NSF, may relieve one nagging fear. Meltwater ponds fracturing the ice below them may not ...
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...

2019/10/21
Our knowledge of dwindling sea ice coverage in the Arctic Ocean comes mostly through satellites, which have imaged sea ice from above since 1979. The University of Washington Pan-Arctic Ice Ocean and ...
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...
Scientists solve long-standing mystery:Why atmospheric carbon dioxide was lower during ice ages（图）
Scientists long-standing mystery atmospheric carbon dioxide lower during ice ages
2019/10/28
Since scientists first determined that atmospheric carbon dioxide was lower during ice ages than during warm phases, they have looked at why, theorizing that it may be a function of ocean circulation,...
