Direct observations of melting, freezing, and ocean circulation in an ice shelf basal crevasse
Ocean conditions near the grounding zones of Antarctica's ice shelves play a key role in
controlling the outflow and mass balance of the ice sheet. However, ocean observations in …

Pathways and modification of warm water flowing beneath Thwaites Ice Shelf, West Antarctica
Thwaites Glacier is the most rapidly changing outlet of the West Antarctic Ice Sheet and adds
large uncertainty to 21st century sea-level rise predictions. Here, we present the first direct …
