This $248,000 Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) will support a collaborative research project to investigate past Arctic sea ice coverage and its impacts on marine ecosystems. The research team at the University of Massachusetts Boston will analyze ocean sediment cores to reconstruct Arctic sea ice extent and ocean conditions over the past 150,000 years, focusing on the Holocene Thermal Maximum and Last Interglacial warm periods....
This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will provide $462,000 to the University of Washington to investigate Arctic sea ice coverage and ocean conditions over the past 150,000 years. The research team will use advanced geochemical techniques, including helium and thorium isotopes and nitrogen isotope analyses, to reconstruct historical sea ice extent and ocean nutrient levels. This data will be collected from sediment cores spanning a range of...
This National Science Foundation (NSF) Polar Programs grant, awarded under CFDA 47.078, supports a research project at the University of New Mexico (UNM) to study the physical and chemical drivers of carbon cycling in Arctic landscapes. The $149,288 award will fund one postdoctoral researcher and analysis of field samples collected from the Canning River in Alaska. The project aims to develop a model simulating carbon flow across the Arctic landscape, including the transformation of...
This $590,883 Project Grant from the National Science Foundation Division of Polar Programs will fund research into sea ice-ocean exchange of microplastics in the Arctic. The grant was awarded on March 1, 2022 to the Regents of the University of Colorado under the NSF's Polar Programs CFDA number 47.078. Through a combination of laboratory studies and numerical modeling, researchers will develop new techniques to understand the uptake and release of microplastics between sea ice and ocean water,...
The University of Connecticut was awarded a two-year, $272,619 project grant from the National Science Foundation Division of Polar Programs to conduct research titled "Carbonate System Dynamics and Biogeochemistry in a Changing Arctic." The grant was awarded on June 1, 2021 with a completion date of May 31, 2023. Under the NSF's Polar Programs, which supports basic research in the polar regions under Assistance Listing Number 47.078, the University will analyze the carbonate system...
This $5,526,178 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) supports the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM3) project. The overarching goal is to transform understanding of the Southern Ocean's role in global carbon, heat, and nutrient cycles during a period of unprecedented climate change. Key activities include extending a circumpolar array of biogeochemical profiling floats to 13 years, enhancing biological...
This $194,921 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund collaborative research to constrain and understand regional modes of variability in the Atlantic Arctic over the next two years. The overarching goal is to quantitatively study climate patterns and their long-term changes in the Atlantic Arctic and sub-Arctic regions using a variety of data sources, including meteorological measurements, historical observations, and climate...
The University of Hawaii at Manoa was awarded a $912,167 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) to characterize key components of biological carbon cycling in the Pacific Ocean through March 2026. Under the award, the university will use profiling floats equipped with oxygen and particulate carbon sensors to measure production and respiration rates across the Pacific Ocean on a daily basis and over all seasons. Ship-based measurements will also...
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 $369,854 National Science Foundation Division of Polar Programs project grant will support research to further understanding of Arctic sea ice variability in the 20th century. Specifically, the University of Washington will produce a new, physically realistic reconstruction of Arctic sea ice and sea surface temperatures during the 20th century. This reconstruction will be used to study Arctic sea ice during the early 20th century warming period from 1915 to 1940, when the Arctic warmed...
