Assessing and modeling past and future glacier mass and runoff changes in response to climate change from local to global scales; contribution of glacier wastage to global sea-level rise; glacier meteorology and hydrology; effect of refreezing on mass change of the Greenland ice sheet.
Activities included collaboration with Dr. Matthias Huss on 21 century global-scale glacier projections within the Glacier Model Intercomparison Project GlacierMIP. Results from 11 glacier models and more than 270 model runs indicate substantial glacier loss by the end of the century. Results were submitted to 'Earth’s Future’ as part of a community paper (Marzeion et al., submitted). The current generation of global-scale glacier models does not include the effects of debris cover on glacier melt, although substantial melt suppression can occur if debris cover exceeds a certain thickness, while melt is enhanced over thin debris cover. The development of a review paper on effects of supraglacial debris on glacier behavior has been explored in collaboration with Dr. Francesca Pelliciotti’s group. In addition, collaboration has been initiated with Dr. Derek Houtz on melt detection over firn of the Greenland ice sheet. Efforts are underway to exchange data and enhance collaboration on satellite derived liquid water content and stratigraphy data of shallow firn cores in Greenland to provide ground truth data for both Houtz’ and Hock’s ongoing projects.
