Broughton Island–a reference area for Wisconsin and Holocene chronology and sea level changes on eastern Baffin Island

Abstract
Broughton Island is 50 km from the eastern margin of the 6,000 km2 Penny Ice Cap. During the early Wisconsin (> 54,000 BP) A younger glacial readvance is delimited by lateral moraines and glacio‐marine deposits 14C dated at 24,100±850 BP; sea level was±18 m. During th last Wisconsin the glaciers terminated some distance inland from Broughton Island and sea alevel at 9,850±250BP was +5 m on Broughton Island. The head of Maktak Fiord, which presently contains a majour outlet glacier from the Penny Ice Cap, was deglaciated about 6,000 BP.
