- This two-year, $267,912 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research to improve paleoclimate proxy records in high-latitude regions. The principal investigator, George Mason University, will develop new and refine existing trace element to calcium ratio paleoproxies using planktic foraminifera species from the Northern California Current region. The research aims to establish temperature and salinity calibration relationships,...
- This National Science Foundation (NSF) Project Grant award, funded under the Geosciences program (CFDA 47.050), provides $533,560 to the Woods Hole Oceanographic Institution (WHOI) to develop a quantitative physicochemical framework for accurately interpreting elemental variations in coral skeletons. The key objectives are to: Construct a physicochemical model to simulate microscale (micrometer-scale) elemental variations, such as magnesium, lithium, and strontium, in coral skeletons. Develop...
- 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...
- This $683,266 Project Grant awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) aims to reconstruct global ice volume and bottom water temperature over the past 1-3 million years. The project at Brown University will analyze multiple climate proxies, including biomarkers and stable isotopes, using machine learning algorithms to resolve global ice volume and ocean temperature signals. The key objectives are to assess the role of CO2 and ice albedo in global...
- This three-year, $232,034 project grant from the National Science Foundation Division of Ocean Sciences' Geosciences program (CFDA 47.050) will fund research to improve reconstructions of past sea surface temperatures. The Ohio State University will work to test and refine approaches for extracting seasonal and mean annual temperature signals from geochemical proxies of past sea surface temperatures. They will also produce new paired foraminifera-magnesium/calcium and alkenone derived sea...
- This $711,586 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research at North Carolina State University to analyze thirty years of foraminiferal assemblages from the Santa Barbara Basin. The grantee will create a record of planktic foraminifera abundances from stored samples collected in the basin and connect the results to modern oceanographic measurements and older seafloor sediments. This will improve understanding of how climate change has...
- This three-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $586,098 to Texas A&M University to conduct research reconstructing ancient ocean temperatures during the Devonian-Mississippian climate transition. The university will test whether tropical ocean temperatures reached extremely high levels of 95-104 degrees Fahrenheit during the time of early animals. It will examine the role of rapid cooling in triggering biotic crises and explore...
- This National Science Foundation Project Grant of $614,058 will fund research at San Diego State University from September 2022 to August 2025 under the Geosciences program (CFDA 47.050). The award will support efforts to improve reconstructions of past sea surface temperatures through developing methods to extract seasonal and mean annual temperature signals from geochemical proxies. Researchers will test approaches for correcting seasonal biases in proxy records against climate model...
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 coefficients for lithium and magnesium. Core top samples will be used to calibrate the response of benthic foraminifera species to cold waters. Sediment cores from the Atlantic will help test the ability to distinguish glacial ocean water masses during the Last Glacial Maximum using this proxy. The research also provides support for student participation and will advance understanding of past ocean circulation changes and carbon storage critical to projecting future climate change within the context of the NSF's mission to expand basic geoscience knowledge.
