Younger Dryas ice margin retreat triggered by ocean surface warming in central-eastern Baffin Bay
The transition from the last ice age to the present-day interglacial was interrupted by the Younger Dryas (YD) cold period. While many studies exist on this climate event, only few include high-resolution marine records that span the YD. In order to better understand the interactions between ocean,...
