A stacked mixing sequence at the base of the Dye 3 Core, Greenland
This paper documents, by a detailed isotopic and gas composition study of the basal ice from the Dye 3 core, a large degree of flow-induced mixing at the ice sheet base. This mixing results most probably from circular motion in troughs of bedrock undulations and flow separations with some entrainmen...
