Abstract
AbstractInformation concerning the supply area of Morsárjökull, a small outlet glacier of Vatnajökull, was derived from a firn profile measured in a pit 6 m. deep.The conspicuous bulge on the medial moraine is, by extrapolation from the annual movement, attributed to a former glacial recession between 1890 and 1900. This bulge is correlated with discontinuous moraines near the head of Skeidarárjökull.Moraines indicating a former greater extension of the glacier are mentioned and evidence showing the recent rapid retreat and thinning of the glacier is presented.
