Ice-sheet variability around the North Atlantic Ocean during the last deglaciation
Article Abstract:
New research supports the view that the release of icebergs and meltwater during Heinrich event 1 caused changes in the North Atlantic thermohaline circulation. These changes prompted a delay or reversal of deglaciation of the Northern Hemisphere and at least as far south as 40 deg S for between two and three thousand years. Most significantly, discharge of icebergs to the North Atlantic from the Laurentide Ice Sheet would have rapidly reduced formation of North Atlantic Deep Water, bringing about cooling in the North Atlantic region.
