An extensive dead-ice area has developed at the stagnant snout of the Holmströmbreen glacier, Svalbard, following its last advance during the Little Ice Age (LIA). The most common landform is ice-cored slopes hosting sediment gravity flows. Dead-ice melting is described and quantified through field studies and analyses of high-resolution, multi-temporal aerial photographs and QuickBird 2 satellite imagery. Field measurements of backwasting of ice-cored slopes indicate melting rates of 9.2 cm/day. Downwasting rates reveal a dead-ice surface lowering of 0.9 m/yr from 1984 to 2004. The volume of melted dead-ice in the marginal zone since the LIA is estimated at 2.72 km3. Most prominently, dead-ice melting causes the growth of an ice-walled lake with an area increasing near-exponentially over the last 40 years. Despite the high-Arctic setting, dead-ice melting progresses with similar rates as in humid sub-polar climates, stressing that melt rates are governed by processes and topography rather than climate. We suggest that the permafrost and lack of glacier karst prevent meltwater percolation, thus maintaining a liquefied debris-cover where new dead-ice is continuously exposed to melting. As long as backwasting and mass movement processes prevent build-up of an insulating debris-cover, the de-icing continues despite the continuous permafrost.
