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 ...
