Ice-Atmosphere interactions

The ice forms by the slow transformation of snow into ice. Changes in precipitation patterns or in surface temperatures directly affect the mass balance of the ice sheets. Surface meltwater also can make its way to the bed, potentially changing basal conditions on different temporal time scale, and also affect the rate of undercutting at glacier termini. Ice-atmosphere interactions are an important focus of our research group. Our current projects include the analysis of the sensitivity of glacier systems on short and long (Holocene) time scale, the development of better Positive Degree Day schemes, and the impact of uncertainty in surface mass balance on short term projections.
