The Rolls on the Ellesmere Ice Shelf
Surface rolls are characteristic features of both the Ellesmere ice shelf and the floating ice islands derived from it. These surface features are described and their origin and evolution discussed. Various theories of origin are considered which involve such forces as pressure from the polar pack,...
