This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $356,512 to The Trustees of Columbia University in the City of New York to develop a new modeling framework for assessing the impact of groundwater processes on Antarctic ice sheet dynamics and sea level rise. The project will incorporate novel hydromechanical couplings between ice sheets, subglacial drainage systems, and groundwater aquifers, with the goal of testing hypotheses about how...
This Project Grant award of $184,798 from the National Science Foundation's Polar Programs (CFDA 47.078) will support research to investigate temporal variations in the glacial and subglacial structures of Antarctica. The key products of this 3-year project, running from September 2024 to August 2027, will include:
A comprehensive analysis of over 20 years of seismic data collected from more than 600 stations across Antarctica to study seasonal and long-term changes in the physical...
This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $126,121 to The Regents of the University of Colorado to conduct research on temporal variations in glacial and subglacial structures of Antarctica. The award aims to improve understanding of how continental-scale Antarctic and Greenland ice sheets are responding to climate change and contribute to sea level rise. The research will leverage seismic data to analyze changes in near-surface and...
This $201,779 Project Grant award, funded by the National Science Foundation (NSF) under the Polar Programs (CFDA 47.078) grant program, will support a collaborative research project on the dynamics of ice shelf boundaries in Antarctica. The research will feature on-site glaciological and geophysical field surveys near pressure ridges along the coast of Ross Island, an area critical for logistics access to major Antarctic research stations operated by the U.S. and New Zealand. The project...
This $840,173 federal Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) will support research to investigate the characteristics of dense shelf water formed within Terra Nova Bay in the Ross Sea, Antarctica, and its subsequent transformation, modification, and northward spreading. The project aims to provide a coordinated, synchronous observational study of this seaward spreading from formation to export across the continental shelf edge and descent...
This federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $325,213 to Columbia University to investigate the role of meltwater in governing the geophysical properties of deforming icy systems, with the goal of improving models of glacial flow and sea level rise. The research will employ experimental deformation tests under compression, torsion, and combined compression-torsion conditions to analyze how meltwater and solid ice orientations...
This $578,675 federal Project Grant award was provided by the National Science Foundation's Polar Programs (CFDA 47.078) to the University of Chicago. The grant will fund collaborative research to study the dynamics of compressive boundaries where Antarctic ice shelves flow against obstructions such as islands and grounded ice. The research aims to understand how these boundary conditions impact the flow of inland ice into the ocean and contribute to sea-level rise. Key research activities...
This $663,419 three-year Project Grant from the National Science Foundation's Polar Programs will fund research at Woods Hole Oceanographic Institution investigating the role of coastal polynyas in modulating Antarctic marine-terminating glacier drawdown. The research will analyze observational data including ice-penetrating radar, radar and laser altimetry, and in situ hydrographic data in conjunction with ocean and ice sheet modeling to examine the interaction between polynya circulation...
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...
This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $131,652.00 to Appalachian State University to conduct collaborative research on frontal ablation processes on lake-terminating glaciers and their role in glacier change. The primary objectives are to quantify the amount of additional ice lost through iceberg production and underwater melt on three large glaciers draining the Juneau Icefield that end in lakes, and to develop computer models...
