Description:A delay in autumn sea ice formation is an important consequence of Arctic Amplification. Baffin Bay is one such region impacted by delayed ice formation, though spatiotemporal analyses to date have not detailed the evolution and drivers of such autumn ice changes. In this study, we document abrupt Baffin Bay sea ice cover changes in the key transition month of October from 1950 to 2021. The ice cover mean and variance dramatically change from 2001 onward with a transition to largely ice-free conditions in the northeast and thinner ice in the northwest. Ocean model experiments attribute these changes to warming of the Atlantic-origin water (AOW) flowing into northeastern Baffin Bay from the south. Transport and upwelling of
