C24C:
Understanding Ice Sheet Surface Melt II
Submit an Abstract to this Session
Session ID#: 34054
Session Description:
Runoff from Greenland surface melt contributes a large fraction of the ice sheet’s ongoing mass loss, and surface melt-induced processes such as hydrofracture and ice cliff failure have the potential to lead to additional large future ice losses from the Antarctic ice sheet. Our understanding of the factors driving surface melt at both poles, as well as how surface melt impacts ice dynamics, is limited by a short observation period, high spatial and temporal variability, and a complex set of dynamics between the atmosphere, ocean, and ice sheet. Unraveling these complex relationships is necessary for advancing our ability to understand ice sheet mass balance and predict its future impact on sea level rise. Abstracts are requested for a session on improving our understanding of ice sheet surface melt variability and dynamics, including how surface melt and surface melt-induced processes are observed, quantified, and modeled in the past, present and future.
