This $286,206 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) supports research on the dynamics of boundaries where Antarctic ice shelves flow against obstructions such as islands and grounded ice. The research will feature on-site glaciological and geophysical field measurements near pressure ridges along the coast of Ross Island, an area affecting access to major U.S. and New Zealand Antarctic logistical hubs. The field data will be combined with...
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...
The National Science Foundation Division of Polar Programs awarded a $132,303 project grant to Columbia University under the Polar Programs federal grant program (CFDA 47.078). The grant will support collaborative research to improve understanding of past variability in glaciation in the Weddell Embayment and Antarctic Peninsula regions. Eleven investigators from seven U.S. institutions and Argentine collaborators will study sediment cores from the International Ocean Discovery Program as well...
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 Project Grant award, provided by the National Science Foundation's Polar Programs (CFDA 47.078), supports research to explore the dynamics of boundaries where Antarctic ice shelves flow against obstructions such as islands and grounded ice. The $859,378 award, effective from September 1, 2024 to August 31, 2027, will fund glaciological and geophysical field surveys, remote sensing, numerical modeling, and theory development to better understand how these compressive ice shelf boundaries...
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 three-year project grant from the National Science Foundation Division of Polar Programs, titled "Collaborative Research: Site Survey for Subglacial Bedrock Exposure Dating at the Margin of the Wilkes Basin in Northern Victoria Land," provides $116,342 to support basic research activities that are best conducted in Antarctica's polar regions. Funded under the NSF's Polar Programs (CFDA 47.078) to expand fundamental polar knowledge and understanding, the award will allow the...
This Project Grant award of $231,050 from the National Science Foundation's Polar Programs (CFDA 47.078) will fund research to investigate the mechanisms that relate ocean circulation in the open ocean to ice sheet melt in Antarctica. The primary objectives are to: 1) Quantify the pathways of Circumpolar Deep Water from its origin in the Antarctic Circumpolar Current to the Antarctic continental slope, and 2) Determine the physical mechanisms that govern the variability of these pathways. The...
This Project Grant award of $703,638, provided by the National Science Foundation (NSF) under the Polar Programs (CFDA 47.078) federal grant program, aims to advance the understanding of the dynamic interaction between mantle flow, crustal deformation, and topography beneath Antarctica. The research objectives include addressing the evolution and uplift of the Marie Byrd Land hotspot, investigating the interplay of mantle processes and tectonic forces during rift evolution in the West...
The National Science Foundation Division of Polar Programs awarded a $144,459 project grant to Columbia University under the Polar Programs federal grant program (CFDA 47.078) for the period of January 1, 2022 through December 31, 2023. The grant funding supports the collaborative research project "GENERATION OF HIGH RESOLUTION SURFACE MELTING MAPS OVER ANTARCTICA USING REGIONAL CLIMATE MODELS, REMOTE SENSING AND MACHINE LEARNING." Through this effort, Columbia University researchers...
