This $365,989 National Science Foundation project grant supports research on nitrogen isotope dynamics on the Amundsen Sea continental margin in Antarctica through the Geosciences program. The grantee, Princeton University, will collaborate with other researchers on the U.S. GEOTRACES GP17-ANT expedition to study the operation of the nitrogen cycle and determine major sources and sinks of biological productivity on this segment of the Antarctic continental shelf. Full depth profiles of...
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...
The Trustees of Princeton University were awarded a $100,344 Project Grant from the National Science Foundation Division of Ocean Sciences. The grant falls under the NSF's Geosciences program (CFDA 47.050), which supports basic research in the atmospheric, earth, and ocean sciences to strengthen the national scientific enterprise. Specifically, the award will fund collaborative research between October 1, 2021 and September 30, 2024 to study export and remineralization rates of bioactive and...
This $582,005 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by The Trustees of Princeton University to investigate nitrous oxide (N2O) consumption in the surface ocean. The research aims to determine the factors that control or stimulate N2O reduction in surface waters and characterize the microbes responsible for the process. Specifically, the investigators will perform 15N tracer incubations to measure the rate of N2O reduction...
This National Science Foundation project grant of $328,355 will fund research into nitrogen isotope dynamics on the Amundsen Sea continental margin in Antarctica under the Geosciences program (CFDA 47.050). Trustees of Boston College, doing business as Boston College, will collect full water column profiles of nitrogen and oxygen isotope ratios in nitrate along with isotope ratios of total dissolved nitrogen at select stations during the U.S. GEOTRACES GP17-ANT expedition. Suspended particle...
The Trustees of Princeton University was awarded a $444,995 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will support collaborative research to reconstruct past changes in oxygen-deficient zones of the eastern tropical North Pacific Ocean through geochemical analysis of fossil plankton in deep-sea sediment cores over the last 3.3 million years. The research aims to clarify controls on...
This Project Grant from the National Science Foundation Division of Ocean Sciences provides $239,096 to the University Enterprises, Inc. doing business as Sacramento State Sponsored Research for collaborative research titled "Southeast Pacific and Southern Ocean Seawater Isotopes Determined from US GEOTRACES GP17-OCE and GP17-ANT Samples." The research will be conducted from July 1, 2021 through June 30, 2024 under the NSF's Geosciences program (CFDA 47.050). The Geosciences program...
The Trustees of Princeton University were awarded a $413,843 Project Grant from the National Science Foundation Division of Ocean Sciences on September 1, 2021 to complete work by August 31, 2024. The grant falls under the NSF's Geosciences program (CFDA 47.050), which aims to expand fundamental knowledge and understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Specifically, the funding will support Princeton University's research project...
The National Science Foundation Division of Ocean Sciences awarded a $471,806 Project Grant to Princeton University from August 1, 2021 to July 31, 2024 under the Geosciences program (CFDA 47.050). The grant supports collaborative research to directly determine and model analyze the elemental stoichiometry of phytoplankton in the Oregon Coast. Princeton University will work with Oregon State University to obtain data on elemental stoichiometry and other plankton and environmental properties to...
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...
