Project Grant 2234875
- 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...

The instrument will enable advanced analyses of important environmental and biological compounds, promoting new research ideas, collaborations, and research directions across multiple departments at Brown. The award period runs from...
- This $106,572 federal Project Grant award from the National Science Foundation's Integrative Activities (CFDA 47.083) program supports research to improve climate reconstructions and quantify the preservation of organic biomarkers in marine sediments. The primary awardee, President and Fellows of Middlebury College, will employ a latitudinal transect of existing sediment cores from the Line Islands region of the equatorial Pacific to investigate how variations in bottom water oxygen conditions...
- This three-year Project Grant from the National Science Foundation Division of Ocean Sciences provides $384,286 to President And Fellows Of Harvard College for collaborative research titled "ILLUMINATING THE CENOZOIC ALKENONE PCO2 RECORD." The research aims to strengthen understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences, as outlined in the NSF's Geosciences program (CFDA 47.050). Specifically, the funding will support...
- This $713,951 Project Grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) supports research into the adaptability of phytoplankton carbon dioxide concentrating mechanisms to changing climatic conditions. The grant to Columbia University will fund experiments to quantify the plastic and adaptive responses of carbon fixation in five key phytoplankton groups - diatoms, dinoflagellates, green algae, coccolithophores, and cyanobacteria - under climate change...
- This $300,785 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project to characterize the chemical composition and bioavailability of dissolved organic matter released by marine nitrifying microorganisms. The project aims to determine how this material contributes to carbon cycling in the deep ocean, which may help improve biogeochemical models and inform potential marine carbon dioxide removal activities. The research will...
- This Project Grant award, worth $905,118, was provided by the National Science Foundation Division of Polar Programs under CFDA Program 47.078 to the University of Rhode Island Research Office. The funding will support a collaborative research project examining how the chemistry of fossil diatoms (a type of plankton) can be used as proxies to reconstruct past changes in ocean nutrients and biological productivity, which are linked to global climate change. The research will involve field...
- This National Science Foundation Project Grant award of $1,086,964 provides funding to Brown University from July 1, 2022 through June 30, 2025 to develop improved reconstructions of global temperatures during the Miocene climate transition approximately 14 million years ago. The award is made under the Geosciences program (CFDA 47.050) to strengthen understanding of integrated Earth system processes through basic research in atmospheric, earth, and ocean sciences. Specifically, the university...
- 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 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 $304,397 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund the development of sensitive and time-saving analytical methods to quantify long chain alkenones in ocean and lake environments. Alkenones are biomarkers produced exclusively by certain microalgae that provide insights into past climate and aquatic productivity when measured in geological sediments. The awardee, Brown University, will optimize reversed phase high performance liquid chromatography-mass spectrometry (HPLC-MS) methods with unprecedented sensitivity and selectivity for analyzing alkenones. Work will include testing liquid chromatographic conditions and mass spectrometry parameters to maximize separation and detection of the target compounds. A series of algal culture samples grown at different temperatures will serve as calibration standards. The validated methods will then be applied to a large set of global ocean surface sediments to fully evaluate performance in complex environmental samples. In addition to advancing climate science, the project provides research support for graduate and undergraduate students.
