C43A:
Modeling of the Cryosphere: Glaciers and Ice Sheets II

Submit an Abstract to this Session



Session ID#: 34027

Session Description:
This session focuses on process-based modeling of glaciers and ice sheets that improves our understanding of ice dynamics or enhances the capabilities of current models. We invite contributions from a broad range of theoretical, numerical, or experimental studies that explore new or improved representations of physical processes relevant to ice flow. The range of topics that is encouraged includes, but is not limited to: basal processes (such as glacial hydrology, erosion, surging, the onset of ice streams), mechanical and thermodynamic processes (constitutive relationships, material behavior, ice fracturing), and ice-ocean interactions (for example calving, grounding line dynamics).
