This Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), provides $269,022 to support research aimed at improving ice shelf instability and breakup modeling. Specifically, the University of California, Los Angeles will develop a new component for the continental-scale Ice Sheet and Sea Level System Model to simulate surface meltwater-induced flexure, fracture, and large-scale ice shelf breakup. To achieve this, the researchers will first create a coupled process-scale model of ice shelf hydrology-flow-flexure-fracture. They will then use this model to quantify relationships between surface meltwater processes, ice flow, viscoelastic flexure, and hydrofracture. These relationships will be translated to the ice sheet scale through a statistical emulator, providing a new approach to multi-physics modeling of surface meltwater-driven ice shelf collapse at various scales. Broader impacts include public outreach through a children's web application and interactions with an artist collective. The research aims to advance sea level rise projections through improved Antarctic ice shelf instability modeling under climate change scenarios.
