Project Grant 1624310

This three-year project grant from the National Science Foundation's Geosciences program ($458,232) supports the theoretical and practical development of aragonite lithium-magnesium ratios as a proxy for reconstructing deep sea paleotemperatures. The University of Colorado will test four hypotheses to improve the theoretical underpinnings and field calibration of this emerging paleothermometer tool. Laboratory experiments will examine the temperature dependence of aragonite partition...

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 three-year, $408,968 National Science Foundation project grant funds research at the University of Chicago to improve estimates of ancient ocean pH and atmospheric carbon dioxide concentrations through analysis of boron isotope ratios in halite evaporites. The researchers will investigate boron behavior in halite formations to determine boron hosting phases like fluid inclusions or trace minerals. Experimentally precipitated halites, natural salt cores, and a 36 million year old marine...

This Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), will support research to investigate the distribution and origin of water in coral skeletons. The $225,632 award to St. Olaf College, spanning 3 years from September 2024 to August 2027, aims to create 2D and 3D maps of water in lab-grown coral skeletons using nanoscale imaging techniques. The research will also test the ability of coral skeletons to retain water and determine whether the...

The National Science Foundation (NSF) awarded a $284,600 Project Grant under the Geosciences program (CFDA 47.050) to the University of Rhode Island (URI) Research Office Division. The 3-year grant supports a collaborative research project to investigate the connections between deep Earth volatile cycles and surface processes, with a focus on the role of water in driving plate tectonics and other geological phenomena. The research will utilize seismic data and geochemical analysis of rock...

This Project Grant from the National Science Foundation Division of Ocean Sciences provides $934,762 to Oregon State University under the Geosciences program (CFDA 47.050) from July 15, 2022 to June 30, 2025. The funding supports collaborative research to better understand the geochemistry of neodymium isotopes and rare earth elements in the North Atlantic Ocean and their influence on deep water circulation patterns. The researchers hypothesize that ocean sediments are a major source of...

This $172,778 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research to test climate model predictions of hydrologic change in the tropical Atlantic during a past warm period. Specifically, the awardee, Utah State University, will geochemically analyze oxygen isotopes and magnesium-to-calcium ratios in planktonic foraminifera from deep-sea sediment cores at several sites, including Ocean Drilling Project Site...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will provide $709,875 to the Woods Hole Oceanographic Institution (WHOI) from September 1, 2024 to August 31, 2027 to reconstruct intermediate and deep water formation in the North Pacific over the past 25,000 years. The project will generate new stable isotope and trace element data from benthic foraminifera to calculate the air-sea component of carbon-13 (δ13Cas), a promising water mass tracer for...

This Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), will fund collaborative research to characterize the role of reverse weathering reactions on marine silicon (Si) and lithium (Li) isotope mass balances. The total award amount is $275,425 and the project period runs from July 15, 2024 to June 30, 2027. The research will study reverse weathering signatures within major sediment depocenters, such as the Amazon Delta, French Guiana Mobile...

This three-year, $384,577 project grant from the National Science Foundation's Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will support collaborative research to construct robust temperature and ice volume histories during the late Cretaceous and Cenozoic periods (approximately 77-0 million years ago). The University of Rochester will utilize benthic foraminiferal test compositions from sea floor sediments to develop proxy records of deep ocean temperatures,...
