Collaborative Research: Sensitivity of Local Glaciers in Central East Greenland to Holocene Climate Change
This award will support an investigation of Holocene glacier fluctuations in the Scoresby Sund region of central East Greenland (~70-72¿N, 22-28¿W) along a transect from a coastal maritime setting to the continental conditions adjacent to the Greenland Ice Sheet. The 'Intellectual Merit' o...

This award will support an investigation of Holocene glacier fluctuations in the Scoresby Sund region of central East Greenland (~70-72¿N, 22-28¿W) along a transect from a coastal maritime setting to the continental conditions adjacent to the Greenland Ice Sheet. The 'Intellectual Merit' of the proposed study lies in the potential to affirm, or otherwise, the widely-held view that the scale of glacier and ice sheet change being observed today in Greenland is not unique in the Holocene. The current recession of glaciers in the Scoresby Sund region is exposing sub-fossil vegetation that grew at times when glaciers were smaller than at present. These emerging records yield a rare opportunity to examine both the biota of these warm times and, more critically, the response of the glaciers to temperatures as high as, or higher than, at present. Development of a chronology for a network of sites in the Scoresby Sund region, including a site adjacent to the Renland ice core, across an environmental gradient can provide insights into recent patterns of ice sheet distribution.
