  • Description: <p>Changes which have taken place during the last hundred years at the north-eastern glaciers of Svartisen are well-documented. Although the period has been characterised predominantly by glacier retreat, the rates of retreat have varied, as have changes of ice thickness at different altitudes. Comparisons of photogrammetric maps from 1945, 1968, 1975 and 1981 illustrate the differences, both temporal and spatial, at the two largest glaciers. Since 1945, a gradual increase of surface slope of the lower part of Fingerbreen has accompanied a fairly uniform decrease of thickness (about 3 m a<sup>-1</sup>). Above 500 m, however, the surface slope has changed little and the rate of decrease of ice thickness has not exceeded 2 m a<sup>-1</sup>. Minor advances of Fingerbreen have interrupted its recession and formed low transverse till ridges. At Lappebreen, retreat almost ceased between 1975 and 1981; above 600 m, the glacier thickness increased. Future studies of glacier change will be a valuable contribution to water resource investigations.</p>
