This National Science Foundation (NSF) Polar Programs (CFDA 47.078) Project Grant award of $286,206 to the University of Maine System will fund research exploring the dynamics of where Antarctic ice shelves compress against obstructions. The research aims to better understand how these "compressive boundaries" impact the flow of ice sheets into the ocean and affect sea level rise. The project will feature on-site glaciological and geophysical field measurements near pressure ridges...
This federal Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) provides $368,061 to The Regents of the University of Colorado (CU), doing business as the University of Colorado, to explore the dynamics of boundaries where Antarctic ice shelves flow against obstructions such as islands and grounded ice. The research aims to understand how these compressive ice shelf boundaries generate forces that impede the flow of inland ice into the ocean, which is...
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 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 $377,603 Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) will fund research by the University of Colorado to investigate the effects of transient and non-Newtonian mantle viscosity on glacial isostatic adjustment (GIA) processes and their implications for GPS observations in Antarctica. The project aims to build an accurate and efficient computer model to study the displacement and deformation of the Antarctic crust and mantle in response to...
This $204,278 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will support research by the University of Chicago to investigate how Arctic sea ice attenuation affects ocean swell, microseisms, and the potential to use seismology as a method for observing sea ice conditions. The key activities include: Analyzing seismic data from stations along the northern coasts of Alaska, Canada, and Greenland to detect seasonal and annual changes in microseisms as a...
The National Science Foundation (NSF) awarded a $126,121 Project Grant under the Polar Programs (CFDA 47.078) to The Regents of the University of Colorado (CU) for a 3-year collaborative research project to study temporal variations in glacial and subglacial structures of Antarctica. The project aims to leverage existing seismic data to better understand how the physical properties of the Antarctic ice sheet change over time, including seasonal variations in subglacial hydrological systems....
This $354,576 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund a postdoctoral research project at Cornell University to investigate the potential impacts of brine firn aquifers on the stability of Antarctic ice shelves. The project aims to: (1) map the extent of brine aquifers across Antarctic ice shelves using airborne ice-penetrating radar data; (2) estimate the liquid water volume in these aquifers; (3) determine how seawater infiltrates the...
This $325,213 Project Grant awarded by the National Science Foundation's (NSF) Division of Polar Programs (CFDA 47.078) to The Trustees of Columbia University in the City of New York will investigate the role of meltwater in governing the geophysical properties of deforming icy systems. The project aims to create new flow laws that explicitly incorporate the effects of meltwater on ice flow, which is a key factor in modeling glacial mass loss and sea level rise. The research will employ...
This Project Grant award of $317,795 from the National Science Foundation Division of Polar Programs (CFDA 47.078) supports research by the Colorado School of Mines to disentangle the internal and basal processes that influence ice sheet flow and contribute to sea-level rise. The project combines satellite remote sensing data with ice-penetrating radar observations to partition the contributions of internal and basal friction within the ice sheet. Key efforts include developing open-source...
