Short summary
Warm ocean water causes rapid melting of Antarctic glaciers. The circulation and mixing of warm water in ice shelf cavities is mostly unknown. We observed ocean currents and mixing under Dotson Ice Shelf. Mixing is low, with patches of higher mixing associated with stronger currents and vertical current shear. The levels of turbulent mixing will lead to negligible heat loss during the path of the warm water to the grounding line, leaving plenty of heat available to melt the ice shelf there.
