Short summary
We predicted how sea level changed in the Ross Sea (Antarctica) due to glacial isostatic adjustment, or solid Earth ice sheet interactions, over the last deglaciation (20 000 years ago to present) and calculated how these changes in bathymetry impacted ice stream stability. Glacial isostatic adjustment shifts stability from where ice reached its maximum 20 000 years ago, at the continental shelf edge, to the modern grounding line today, reinforcing ice-age climate endmembers.
