Project Grant 2147723
- The National Science Foundation's Geosciences Program (CFDA 47.050) awarded a $480,579 project grant to Florida International University (FIU) to develop an improved beryllium-7 sampling system and use it to estimate upper ocean circulation and biological activity rates in the Sargasso Sea. The project will design and build an affordable and efficient in-situ pumping system to collect beryllium-7 from seawater, which will be tested near Florida and then deployed as part of the Bermuda Atlantic...
- This Project Grant award of $819,285.00, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a research project to measure the distribution of the naturally occurring radioactive isotope beryllium-10 in seawater, ocean particles, and sediment samples from the South Pacific Ocean. The objective is to test the hypothesis that the distribution of beryllium-10 in the ocean is primarily controlled by settling particles rather than ocean circulation. The new...
- The Bigelow Laboratory for Ocean Sciences was awarded a $543,189 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to conduct the US GEOTRACES GP17-OCE AND GP17-ANT research project. The three-year award running from October 2021 through September 2024 will support particulate and biogenic trace element studies in the South Pacific and Southern Oceans. As part of the larger Geosciences program goal of expanding...
- This three-year Project Grant from the National Science Foundation Division of Ocean Sciences provides $278,236 to fund collaborative research titled "COLLABORATIVE RESEARCH: US GEOTRACES GP17-OCE: SIZE-FRACTIONATED PARTICLE COLLECTION AND ANALYSIS FROM ULTRA-OLIGOTROPHIC TO ANTARCTIC WATERS." The research will be conducted under the NSF's Geosciences program (CFDA #47.050), which supports basic research in the atmospheric, earth, and ocean sciences to strengthen understanding of the...
- This $480,149 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research project between the University of South Florida and the University of Hawaii. The research aims to measure iron isotopes in seawater samples from three GEOTRACES expeditions in the Pacific Ocean, producing an unprecedented data set. By combining these data with ocean biogeochemical modeling, the project will address important questions about the sources of...
- The National Science Foundation (NSF) awarded a Project Grant of $367,399 to the University of Georgia Research Foundation, Inc. (UGA Research Foundation) under the NSF Geosciences program (CFDA 47.050). This 3-year project, starting in June 2024, will conduct a time-series study of aerosol trace elements in the North Atlantic Ocean near Bermuda. The key objectives are to: Analyze temporal variations in the size distribution of aerosol iron and other bioactive trace elements, and link these to...
- This Project Grant from the National Science Foundation Division of Ocean Sciences provides $549,956 to the University of Miami from October 1, 2021 to September 30, 2024. The funding supports measurements of the trace gases chlorofluorocarbons and sulfur hexafluoride as part of the US GEOTRACES GP17-OCE project. GEOTRACES is a multi-national program studying the global marine biogeochemical cycles of trace elements and their isotopes. The University of Miami will conduct oceanographic...
- This Project Grant from the National Science Foundation Division of Ocean Sciences provides $306,817 to Rutgers, The State University from July 1, 2021 to June 30, 2024. The grant supports collaborative research to determine seawater isotope compositions from samples collected in the Southeast Pacific and Southern Oceans during the U.S. GEOTRACES GP17 oceanographic cruises. This work will strengthen understanding of the integrated Earth system, as described in the objectives of the Geosciences...
- This $194,910 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund collaborative research to advance understanding of trace element biogeochemistry in the Amundsen Sea region of West Antarctica. Rutgers, The State University will analyze approximately 500 suspended particle and sediment samples collected during the NSF's GEOTRACES GP17-ANT cruise to quantify distributions of 40 trace elements. The investigators will...
- This Project Grant award, totaling $261,861.00, is funded by the National Science Foundation's Geosciences Program (CFDA 47.050). The grant supports a collaborative research project led by the University of Washington that aims to improve understanding of how benthic nepheloid layers (BNLs) - persistent layers of enhanced particle concentrations near the seafloor - influence the cycling and budgets of trace elements and isotopes in the Labrador Sea. The key objectives are to: (1) quantify...
This Project Grant from the National Science Foundation Division of Ocean Sciences provides $276,070 to Florida International University for measurement of beryllium-7 as a tracer of upper ocean processes from August 1, 2022 to July 31, 2025. The funding supports measurements of the radioactive isotope beryllium-7 in the water column and on aerosols during the US GEOTRACES GP17-OCE section of the South Pacific and Southern Oceans. Beryllium-7 allows the study of biological production, nutrient regeneration, and atmospheric deposition over seasonal time scales and shallow depths, advancing understanding of integrated Earth system processes as outlined in the Geosciences program (CFDA 47.050) goals. The research aims to identify and quantify fluxes controlling trace element distributions and isotopes with roles as nutrients, tracers of oceanographic changes, and contaminants from human activity, in alignment with the International GEOTRACES Program's objectives.
