Gas isotopes in ice reveal a vegetated central Greenland during ice sheet invasion
International audience Environmental conditions prevailing during build-up of the Greenland Ice Sheet (GIS) are not yet established. Here we use results from gas isotopes from basal ice of the GRIP ice core to show that central Greenland was vegetated during invasion by the ice sheet. The δ 13CCH4 a...

International audience Environmental conditions prevailing during build-up of the Greenland Ice Sheet (GIS) are not yet established. Here we use results from gas isotopes from basal ice of the GRIP ice core to show that central Greenland was vegetated during invasion by the ice sheet. The δ 13CCH4 and δ 18O of O2 values obtained were never encountered before in ice core studies. Such values are indeed the signature of a significant biological activity. |
