Project Grant 2520980
- This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will provide $922,103 to Dartmouth College to characterize the thermomechanics of subglacial systems and improve understanding of how water moves beneath glaciers and ice sheets. The research aims to resolve discrepancies between observations and existing subglacial hydrology models by incorporating subglacial thermomechanics, particularly the process of ice infiltration into sediments. The project...
- This Project Grant award, funded by the National Science Foundation's (NSF) Polar Programs (CFDA 47.078), will support a collaborative research project to quantify the physics of ice-ocean interactions at the interface of marine-terminating glaciers in Greenland. The $372,486 award, effective September 1, 2025 through August 31, 2029, will integrate direct measurements of submarine melt rates and near-ice boundary-layer dynamics with numerical simulations to improve next-generation climate...
- 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, funded by the National Science Foundation's (NSF) Polar Programs (CFDA 47.078), supports collaborative research to investigate how meltwater from surface channels called moulins affects the subglacial drainage system beneath Greenland's glaciers. The $469,008 award, effective from July 1, 2025 to June 30, 2028, will enable the investigators to conduct a field study using seismic sensors, radar, and ice movement measurements to track the evolution of hydraulic...
- This federal Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) provides $208,083 to support a collaborative research project at Tufts University aimed at quantifying the processes that control boundary layer transport across the ice-ocean interface of tidewater glaciers. The research will utilize a specialized underwater robot with state-of-the-art instruments to observe melt rates and the dynamics of the currents adjacent to the glacier face, as...
- This $700,962 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund a collaborative research study on how meltwater from surface channels affects the subglacial drainage system beneath Greenland's glaciers. The investigators will conduct a field study using seismic sensors, radar, and ice movement measurements to track the evolution of underground drainage cavities and how their connectivity impacts seasonal changes in ice velocity. The research builds...
- 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 $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...
- 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...
- The National Science Foundation (NSF) awarded a $505,036 Project Grant under the Geosciences program (CFDA 47.050) to the Trustees of Dartmouth College to improve predictions of sea level rise driven by ice mass loss from the Greenland and Antarctic ice sheets. The project aims to combine physical understanding of ice dynamics with artificial intelligence techniques applied to satellite imagery datasets, in order to develop physics-informed models of basal sliding and ice calving processes. This...
This Project Grant award from the National Science Foundation's (CFDA 47.078) Polar Programs supports research to investigate the movement of water at the ice-bed interface of glaciers and ice sheets. The $780,179 award, spanning September 1, 2025 to August 31, 2028, will utilize a combination of laboratory experiments and theoretical modeling to (1) derive a model of distributed water flow in the bed-till aperture and within the till, (2) analyze the conditions that determine whether distributed drainage will occur predominantly within the till or at the ice-bed interface, and (3) solve this model numerically to determine how the subglacial water system impacts ice sheet dynamics and contributes to sea level rise projections. The project will support undergraduate and graduate student training, and is expected to lead to an improved understanding of subglacial water flow, which is a key driver of glacier and ice sheet movement.
