The Antarctic is by far the largest body of water (mostly ice in this case) that is not in the sea and therefore potentially important for changing sea level. The large size of the Getz ice shelf and its as yet uncertain potential for melting by oceanic waters below make this an important study for understanding and predicting impacts of a warmer climate.
Short summary
Ice shelves in the Amundsen Sea are thinning rapidly as ocean currents bring warm water into cavities beneath the floating ice. We use 2-year-long mooring records and 16-year-long model simulations to describe the hydrography and circulation near the ice front between Siple and Carney Islands. We find that temperatures here are lower than at neighboring ice fronts and that the transport of heat toward the cavity is governed by wind stress over the Amundsen Sea continental shelf.
