Project Grant 2525190
- 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...
- 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 $269,928 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund research to use beryllium-10 (10Be) anomalies from solar proton events as a method for verifying varve chronologies in Arctic lake sediments. The research team at the University of Massachusetts will analyze 10Be concentrations in laminated sediment cores collected from sub- to high-Arctic lakes to determine if 10Be increases associated with solar proton events can reliably...
- This Project Grant from the National Science Foundation Division of Ocean Sciences provides $469,092 to The Trustees of Columbia University in New York for research titled "COLLABORATIVE RESEARCH: US GEOTRACES GP17-OCE: UNDERSTANDING NEODYMIUM ISOTOPES AND RARE EARTH ELEMENT SYSTEMATICS IN THE SOUTH PACIFIC." The research will be conducted from October 1, 2021 through September 30, 2024. The funding supports basic research within the Geosciences program of the National Science...
- This Project Grant award of $569,967 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research at the California Institute of Technology (Caltech) and the University of Miami. The key objective is to use new tools to measure hydrogen, carbon, and nitrogen isotopes in marine particles in order to better understand the mechanisms and processes governing the formation, composition, and sinking of particulate organic matter (POM) into the deep ocean....
- This Project Grant award for $540,281 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project between U.S. and U.K. scientists to better understand the linkages between the oceanic cycles of iron and carbon. The research aims to characterize the "colloidal shunt" mechanism, whereby dissolved iron forms aggregates with organic carbon to create particulate matter that sinks out of the upper water column. The project will...
- This Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $825,297 to The Trustees of Columbia University for the period of August 15, 2021 through July 31, 2024. The grant supports experimental refinement of the boron isotope proxy in planktic foraminifera to better understand temperature, asensitivity, and seawater elemental composition. A subaward of $50,000 is provided to Vassar College to...
- The National Science Foundation's Geosciences Program (CFDA 47.050) awarded a $599,974 Project Grant to the University of Washington on Aug 1, 2025. This 5-year grant, titled "CAREER: BACK TO THE BEGINNING - REFINING MARINE RADIOCARBON AS A TRACER OF OCEAN CIRCULATION AND TIME IN THE NORTH PACIFIC", will support research to reconstruct ocean ventilation variability from marine sediment cores in the Northeast Pacific over the past 23,000 years. The research aims to address gaps in the...
- This Project Grant award for $197,103, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research effort to better understand the linkages between the oceanic cycles of iron and carbon. The project will integrate field observations from the Bermuda Atlantic Time-series Study (BATS) and Cape Verde Ocean Observatory regions with targeted experimental studies and advanced ocean biogeochemical modeling. Key areas of focus include examining...
- 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 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 data set will provide insights into the processes controlling beryllium-10 distribution and improve the interpretation of past changes in sediment beryllium-10 records. The project will support two early career investigators and the development of Earth science education programs. The award has an ultimate completion date of January 31, 2029 and is being conducted by The Trustees of Columbia University in the City of New York.
