Short summary

Sea ice variability in the eastern Fram Strait between, and within, individual Greenland Stadials and Interstadials is documented by high-resolution proxy reconstructions. Unlike the southeastern Nordic Seas and North Atlantic, these changes were less linked to Greenland climate oscillations. Instead, they were driven by ocean heat transport, regulated by the interplay between the Atlantic Meridional Overturning Circulation strength and sea ice cover in the southeastern Nordic Seas.
