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.本数据集为独立计算铍-10（Beryllium-10，Be-10）年龄所需的输入数据，采样区域涵盖两处：巴芬岛坎伯兰半岛的金收获地区，以及格陵兰西南部锡西米尤特与康格鲁苏阿克之间的区域。数据集总计包含123组年龄数据，同时附带配套的实验室空白数据集。来自格陵兰西南部的Be-10年龄数据限定了全新世早期（约11.7至8.2千年前）格陵兰冰盖西缘的退缩与阶段性停滞过程；来自巴芬岛的Be-10年龄数据则限定了劳伦泰德冰盖边缘及当地高山冰川的退缩、阶段性停滞或冰进过程。
