This study reconstructs the last deglaciation of the Eurasian Ice Sheet's marine sectors, focusing on the retreat of the Norwegian Channel and Barents Sea ice streams. The deglaciation, from a peak volume equivalent to 20 m of sea-level rise, was primarily driven by temperature-forced surface mass balance in the south and Nordic Seas oceanic conditions in the north. The findings highlight the nonlinear response of ice sheets to forcing and the importance of ocean-ice-atmosphere dynamics in assessing the fate of contemporary ice sheets.
