Fabric Analysis of a Core from the Meighen Ice cap, Northwest Territories, Canada
Abstract Ice samples from a 121 m core, representing the total thickness of the Meighen Ice Cap near its highest point, were studied for ice fabric, firn- and dirt-layer distribution. The absence of a strongly preferred fabric between the surface and the base of the ice cap at the core site suggests...
