Abstract
Significant eolian deposition occurred during winter 1990-91 on western Fosheim Peninsula. Snow-cored barchan dunes coated with sand and gravel developed on the sea ice of Slidre Fiord adjacent to an airstrip. Dust was distributed throughout snow layers at many sites and thick blankets of silty clay draped some slopes near Hot Weather Creek base camp. Low regional winter snowfall and the redistribution of snow by strong wind created substantial bare areas which became sources for such deposition. An experiment confirmed that snowmelt could be accelerated by a week by manual dusting of a snow surface. This suggests that dust layers help create the observed zones of early melt. After snowmelt, eolian activity impacts on vegetation by delaying stabilization, by smothering vegetation, or by causing a shift in species dominance.
