Banks Antarctica Ross Sea rich food source emperor penguins
2020/8/14
A new U.S. National Science Foundation-supported study provides some of the most comprehensive evidence to date of the lengths penguins will go for a meal. The results were reported in the journa...

Robotic underwater vehicle snaps first images seafloor beneath Antarctica Thwaites Glacier
2020/2/20
During the first study of the ocean floor beneath Antarctica’s Thwaites Glacier, scientists took images of the glacier's foundations. Thwaites now accounts for about 4% of global sea level rise, and r...
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 ...

Scientists working on the ROSETTA-Ice project, a three-year, multi-institution survey of the Ross Ice Shelf in Antarctica, have assembled an unprecedented view of the seafloor beneath the ice sheet.In...
Some Antarctic fish living in the planet’s coldest waters are able to cope with the stress of rising carbon dioxide levels in the ocean. They can even tolerate slightly warmer waters. But they can’t d...
