This $1,263,530 National Science Foundation award through the Mathematical and Physical Sciences program (CFDA 47.049) will fund research into the dynamics of melting ice. New York University will investigate ice melting through laboratory experiments, numerical simulations, mathematical modeling, and analysis. Researchers will study melting in idealized settings and increasingly complex situations involving changing geometry, temperature, and salinity. Experiments will precisely measure...
The National Science Foundation (NSF) awarded a $356,512 Project Grant under its Polar Programs (CFDA 47.078) to The Trustees of Columbia University in the City of New York to develop a new modeling framework for evaluating the impact of groundwater processes on Antarctic ice sheet dynamics and sea level rise. The project aims to incorporate novel hydromechanical couplings between ice sheets, subglacial drainage systems, and groundwater aquifers to test hypotheses about how aquifers may...
This $397,492 federal Project Grant award was provided by the National Science Foundation (NSF) under its Geosciences Program (CFDA 47.050) to study the melting of ice sheets during the last interglacial period approximately 130,000 to 115,000 years ago. The project, led by The Trustees of Columbia University in the City of New York, aims to better understand when and how much the Greenland and Antarctic ice sheets melted, as well as the climate conditions and ice dynamics that drove their...
This $362,718 National Science Foundation Division of Polar Programs Project Grant will support research to improve model representations of Antarctic ice-shelf instability and break-up due to surface meltwater processes. The Regents of the University of Colorado will receive funding from January 1, 2023 through December 31, 2025 to develop a new component for the continental-scale Ice-Sheet and Sea-Level System Model (ISSM) capable of simulating surface meltwater-induced flexure, fracture,...
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 $346,823 Project Grant award from the National Science Foundation (NSF) Division of Polar Programs, CFDA 47.078, supports research to advance understanding of meltwater flow through glacial firn on the Juneau Icefield in Alaska. The research team at the University of Colorado will: (1) measure changes in surface melt and firn properties critical to firn hydrology, and (2) apply novel water-isotope stratigraphy techniques to determine timing and variability of meltwater infiltration. This...
The National Science Foundation's Division of Polar Programs awarded a $899,856 project grant to The Trustees of Columbia University in the City of New York, on August 15, 2023. The funding supports a collaborative U.S./U.K. research project investigating the direct influence of meltwater on the dynamics of the Antarctic ice sheet. The key activities include a field campaign on Flade Glacier and a continent-wide remote sensing survey to test hypotheses related to how surface meltwater reaching...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $153,335 supports a collaborative research project to study the evolution of frictional interfaces in earthquakes and ice sheet collapse. The project aims to directly observe the coupled processes controlling the nucleation, slip, healing, and melting in ice, using a custom cryogenic biaxial apparatus and a sample of ice atop a glass plate. The research team, which includes collaborators across...
This $191,868 National Science Foundation project grant supports research to understand surface-to-bed meltwater pathways across the Greenland Ice Sheet. Funded through the Polar Programs grant program (CFDA 47.078), the award will utilize machine learning and physics-based models to map cracks and draining lakes on the ice sheet from satellite imagery. Researchers at the University of Kansas Center for Research will develop open-source artificial intelligence codes to automatically detect ice...
The National Science Foundation (NSF) awarded a $505,558 project grant under the Polar Programs (CFDA 47.078) to Oregon State University. The 3-year grant, which began on October 1, 2023, will support a collaborative research project to elucidate the ocean dynamics governing melt at glaciers using Lagrangian floats. The research aims to determine the physical processes causing melting at an Alaskan glacier that ends in a fjord, focusing on whether recirculating cells and waves below the...
