C21A:
Glacier-Ocean Interactions: Observations, Mechanisms, and Synthesis IV Posters


Session ID#: 8012

Session Description:
Spatio-temporal variations in glacier ice-ocean interactions are likely the primary driver of the rapid and global changes in glacier dynamics observed over the past few decades, yet the processes that occur at or near the ice-ocean interface remain poorly understood. This session focuses on the processes that govern interactions at the ice-ocean interface or modulate the coupling between the cryosphere and oceans. We invite contributions from process-focused observational, laboratory, and modeling studies on glacier calving, submarine melting of floating ice tongues, grounded termini, and icebergs/mélange, subglacial plumes, iceberg over-turning and break-up, mélange motion, etc. Given the coupled nature of the glacier-ocean system, we encourage submissions from both the Cryosphere and Ocean Sciences communities.  Studies focused on data synthesis should be submitted to the companion session (Glacier Ice-Ocean Interactions: Synthesis Studies).
