Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...
