Berylium isotope data, Cumberland Peninsula, Baffin Island, and Southwestern Greenland, 2015-2019

Input data needed to independently calculate Beryllium-10 (Be-10) ages. Dataset is from two sites: King Harvest region, Cumberland Peninsula, Baffin Island and in southwestern Greenland between Sisimiut and Kangerlussauq. 123 ages in total. Also included is the associated lab-blank dataset. Be-10 ages from southwestern Greenland constrain the retreat and episodic pause of the western margin of the Greenland Ice Sheet during the early Holocene (~11.7 to 8.2 thousand years ago). Be-10 ages from Baffin Island constrain the retreat and episodic pause and/or readvance of the Laurentide Ice Sheet margin and a local alpine glacier.
