Antarctica’s Astonishing Rebound: Ice Sheet Grows for the First Time in Decades

Mass changes across the Antarctic ice sheet have been detected using satellite gravimetry, revealing significant instabilities in major glacier basins of East Antarctica as well as across the entire ice sheet. The Antarctic Ice Sheet (AIS) plays a major role in global sea-level rise. Since March 2002...Read More

Amid federal research cuts, some Antarctic tourist cruises are sponsoring scientists

During Antarctica’s warm season, the sleek Norwegian passenger ship known as the MS Fridtjof Nansen departs regularly from Argentina for its journey south across the turbulent Drake Passage, down to the Antarctic Peninsula. The cruise carries wealthy adventurers, bucket listers and, increasingly, polar scientists looking to gather data as public…

Ghost Ice vs. Rising Seas: A Surprise Antarctic Freeze Near Doomsday Glaciers

As autumn settled over Antarctica, sea ice began its seasonal return, with NASA capturing striking images of new growth in the Amundsen Sea. The presence of persistent “grease ice” near Pine Island and Thwaites glaciers, both notorious for contributing to sea level rise, has scientists watching closely...Read More

Hot methane seeps could support life beneath Antarctica’s ice sheet

Researchers collecting rock samples in Antarctica in the 1960s Polar Rock Repository Microbes living beneath Antarctica’s ice sheet may survive on methane generated by geothermal heat rising from deep below Earth’s surface. The discovery could have implications for assessing the potential for life to survive on icy worlds beyond Earth.…
