The University of Wisconsin System was awarded a $155,583 Project Grant from the National Science Foundation's Polar Programs (CFDA 47.078) to conduct research focused on constraining iceberg size distributions and their climate impacts in models. The project aims to (1) quantify present-day calving characteristics of glaciers and ice shelves in Greenland and Antarctica to better understand iceberg creation, and (2) estimate how iceberg size distributions will evolve over the coming decades and centuries and assess the resulting global and regional climate impacts. By leveraging process models, observational data, and state-of-the-art ice sheet model output, this research seeks to improve constraints on iceberg simulations and reduce uncertainties in climate projections. The award period runs from September 1, 2024 to August 31, 2029.
