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...
When the temperature drops below freezing, snow and ice often follow. But that's not always the case in Antarctica, where for the first time, drizzle has been recorded at temperatures well below freez...
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 ...
