This Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), provides $371,742 to the University of Washington from January 1, 2023 through December 31, 2025. The funding will support development of a new modeling component for the continental-scale Ice Sheet and Sea Level System Model (ISSM). This new component aims to simulate surface meltwater-induced flexure, fracture, and large-scale ice shelf break-up in Antarctica. To achieve this, the University will first develop a coupled process-scale model of ice shelf hydrology-flow-flexure-fracture (H3F Model). It will then use the H3F 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 new approaches to computationally simulating surface meltwater-induced ice shelf collapse at various scales. Broader impacts include public outreach through a children's web application and collaborations promoting interactive visualization of ice shelf collapse scenarios under climate change.
