Investigations of Dust and Black Carbon Content in Snow from the Juneau Region

Abstract

The role of snow impurities in contributing to reductions in albedo (reflectivity) has been examined for the first time in the Juneau area this past summer, although there are other ongoing studies related to loss of glacier ice.  My proposed project is twofold: 1) to quantify the dust concentrations in the snow samples collected by UAS faculty this summer; 2) to collect a new set of snow samples in late winter/early spring for black carbon and dust along a transect of densely vs lightly populated areas of the city.
