- This two-year, $159,271 Project Grant from the National Science Foundation Division of Polar Programs will support research into microstructure observations of vertical mixing and heat fluxes in the Arctic Ocean. Funded through the NSF's Polar Programs CFDA 47.078, which supports basic research in the polar regions, this award will analyze an existing dataset of 264 shipboard turbulence profiles collected on two Arctic Observing Network cruises. Researchers at the Scripps Institution of...
- 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, $432,824 project grant from the National Science Foundation Division of Polar Programs supports research characterizing eddies beneath Antarctic sea ice. Funded through the Polar Programs program (CFDA 47.078), the collaborative research will derive statistical descriptions of sub-ice eddy properties using hydrographic observations from instruments. High-resolution global ocean and sea ice models will track simulated eddies to identify formation mechanisms. Theoretical...
- This federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $159,734 to Texas A&M University-Corpus Christi to collect critical heat flow and sedimentological data in the Ross Sea, Antarctica. The goal is to study the mechanisms controlling the rate of gas hydrate destabilization following the retreat of the Antarctic ice sheet since the last glacial maximum. The data collected, including heat flow measurements and sediment cores, will inform...
- This $206,966 project grant from the National Science Foundation's Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research at Florida State University to quantify mixing and eddy statistics within the Weddell Gyre of the Southern Ocean. Over the award period from March 2022 through February 2025, the grantee will track 153 RAFOS-enabled Argo floats in ice-covered regions of the Weddell Gyre. Using the resultant float tracks along with other available Argo...
- The National Science Foundation's (NSF) Polar Programs (CFDA 47.078) awarded a $288,448 Project Grant to Oregon State University to conduct collaborative research on using X-ray tomography to characterize the microstructure of sea ice during stress tests. The goal is to develop multiscale numerical models that link the micromechanics of sea ice to its macroscopic behavior, which is critical for improving Arctic navigation, infrastructure design, and climate adaptation strategies. This research...
- 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 Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) is for $423,761 and will be executed from September 1, 2025 to August 31, 2028. The grant will support collaborative research to advance coupled atmosphere-ocean-sea ice modeling of the Antarctic region. The project aims to enhance the representation of atmospheric cloud physics and ocean-sea ice heat exchange in state-of-the-science models. This will enable more realistic simulations of the marine...
- This Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $197,506 to support collaborative research on rapid pilot observations of enhanced near-bottom equatorial turbulence in the deep Pacific Ocean. The University of California San Diego Scripps Institution of Oceanography, as awardee, will leverage an existing mooring array at 140°W to add instrumentation to moorings planned for 0.5°N and 3°N...
- This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $184,798 to The Research Foundation For The State University Of New York (Stony Brook University) to conduct collaborative research on temporal variations in glacial and subglacial structures of Antarctica. The research aims to better understand how seismic properties within and beneath the Antarctic ice sheets change over time, which can provide insights into ice sheet dynamics and responses to...
This $249,475 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund research to understand how turbulent mixing in the ocean affects the stability of Antarctic ice shelves, marine ecosystems, and the ocean's ability to store heat. The research, conducted by the University of Texas at Austin, will collect direct observations of turbulence and vertical mixing processes in the western Weddell Sea region of Antarctica using microstructure profilers deployed from the German research icebreaker RV Polarstern. The study will examine how tides, topography, and wind forcing influence mixing rates and vertical fluxes of heat and nutrients in this remote, understudied region beneath the sea ice. The results are expected to improve model predictions of ocean-ice interactions and contribute to a better overall understanding of the Antarctic climate system. This award will be executed over the period from September 1, 2025 to August 31, 2027.
