Projections of sea level rise in the twenty-first century are highly unclear due to the reaction of the marine-based West Antarctic Ice Sheet (WAIS) to a warming climate.

The destiny of the floating ice shelves situated at the seaward periphery of the ice sheet is dynamically related to its evolution.

Ice-shelf buttressing helps regulate the flow of grounded ice into the ocean by creating a resistive strain near the grounding line where the ice sheet first floats.

Several West Antarctic ice shelves have rapidly thinned during the past few decades due to enhanced ocean-driven basal melting, which has decreased the strength of ice-shelf buttressing.

Between 1994 and 2012, the rate of ice-shelf mass loss rose by 70% (ref. 12), which led to a change in how quickly grounded ice drained into the ocean.

Modified Circumpolar Deep Water (mCDW)22, a single source water mass, drives basal melting. The gradient in the line formed by the Icefin and borehole-based CTD measurements in -SA space is 2.40 0.01 °C (g kg 1).

The Amundsen Sea's ocean conditions change across a large temporal range, which has an impact on the ocean's characteristics and the basal melt rate under the bordering ice shelves30,31,32.
