This three-year, $175,382 Project Grant from the National Science Foundation's (NSF) Polar Programs will fund research investigating the role of coastal polynyas in modulating Antarctic marine-terminating glacier drawdown. The grantee, Dartmouth College, will analyze observational data, derived datasets, and model simulations to examine the interaction between polynya circulation and ice shelves across seven preliminary Antarctic sites. The research aims to establish a framework for interpreting...
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 three-year, $1,083,600 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research examining the dynamics of cross-shelf exchange in an Antarctic slope canyon. The Woods Hole Oceanographic Institution will conduct numerical modeling and laboratory experiments to test hypotheses about dense shelf water transport and the onshore flow of deep offshore water induced by dense water descending the canyon. The...
This $477,793 federal Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) funds a research project at the Woods Hole Oceanographic Institution (WHOI) to investigate the impacts of climate change on the biological carbon pump in the West Antarctic Peninsula (WAP) region. The goal of the project is to develop a novel hybrid modeling framework that integrates observational data from long-term research programs with advanced artificial intelligence and...
The Woods Hole Oceanographic Institution received a three-year, $548,143 Project Grant from the National Science Foundation Division of Polar Programs to conduct collaborative research integrating Antarctic environmental and biological predictability to obtain optimal forecasts. The grant was awarded on September 1, 2021 under the NSF's Polar Programs, which aims to strengthen fundamental polar research conducted in or requiring polar environments (CFDA 47.078). Through this funding, Woods...
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 award of $859,378 from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) supports a collaborative research project exploring the dynamics of ice shelf boundaries in Antarctica. The research aims to investigate areas where floating ice shelves compressively flow against obstructions, as these "crash-zones" generate resistive forces that impact ice sheet contributions to sea-level rise. The project will feature on-site glaciological and geophysical...
The University of California San Diego Scripps Institution of Oceanography will receive $363,261 under a three-year Project Grant from the National Science Foundation Division of Polar Programs. The grant will fund collaborative research titled "Peripheral East Antarctic Ice as a Unique Recorder of Climate Variability During the Last Interglacial" from August 2021 through July 2024. The research aims to strengthen understanding of polar regions by expanding knowledge of climate...
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 $505,558 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...
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 and ice shelves across seven preliminary Antarctic sites. The project aims to establish a framework for interpreting coupled ice shelf-ocean variability across diverse geographic settings. It will test hypotheses regarding correlations between polynya extent and ice shelf melt rates, how polynyas modulate feedback between ice shelf melt and accretion regimes through local water stratification, and how polynyas and seafloor bathymetry regulate warm offshore waters reaching ice margins. Results will provide inputs and validation for coupled modeling examining feedbacks over time in different dynamical regimes. The research directly addresses the Polar Programs' mission to strengthen polar scientific understanding through expanded fundamental knowledge of these regions.
