This three-year, $175,382 Project Grant from the National Science Foundation's (NSF) Polar Programs will fund research investigating the role of coastal polynyas in modulating Antarctic marine-terminating glacier drawdown. The grantee, Dartmouth College, will analyze observational data, derived datasets, and model simulations to examine the interaction between polynya circulation and ice shelves across seven preliminary Antarctic sites. The research aims to establish a framework for interpreting coupled ice shelf-ocean variability and diagnose the spatial variability of polynya-ice shelf interactions. It will assess how polynya extent correlates with and modulates ice shelf melt rates. Results will provide input and validation for ocean and ice sheet models to characterize feedbacks and examine interaction in different dynamical regimes. The work seeks to improve understanding of influences on ice shelf and ice sheet stability and interpret impacts of climate change.
