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...
The National Science Foundation (NSF) Division of Polar Programs awarded a $899,985 Project Grant to the University of California, Santa Barbara (UCSB) with a period of performance from September 1, 2023 to August 31, 2026. The purpose of this grant is to conduct collaborative research on the roles of seasonality, silicification, and alteration in nitrogen and silicon isotope paleo-proxy variability, specifically examining the chemistry of fossil diatoms to understand past changes in surface...
This National Science Foundation project grant award of $1,053,775 provides funding from June 1, 2023 through May 31, 2026 to support research examining the cellular metabolism and physiology of diatom-diazotroph associations (DDAs) and evaluate their ecosystem and biogeochemical impacts. The University of Rhode Island will investigate the responses of DDAs to different nitrogen sources and temperatures, compare DDA physiology and metabolism to asymbiotic diatoms, and model ecosystem-level...
This two-year, $329,660 Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research into Cretaceous-era diatom paleobiology and survivability through major environmental perturbations. Principal Investigator Dr. Coenen will study laminated sediments to better understand early Cretaceous climate variability and diatom taxonomy at Ocean Drilling Project Site 693. This includes evaluating whether modern ecological...
This National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) Project Grant, awarded to New York University (NYU) on August 1, 2024, provides $552,466 in funding over a 3-year period to conduct collaborative research on the phylogeny, systematics, and adaptation of marine epizoic diatoms to endangered megafaunal hosts. The key objectives of this project are to: 1) document and describe up to 50 new diatom species living on marine animals like sea turtles, whales, and manatees;...
This National Science Foundation Project Grant under the Geosciences Program (CFDA 47.050) provides $734,947 in funding to the University of Rhode Island to conduct collaborative research on the life cycle of phytoplankton blooms in coastal ecosystems. The research team will analyze a unique set of samples and data collected in 2021-2022 to better understand the metabolic, functional, and taxonomic interactions between phytoplankton and associated bacteria that influence the timing and...
This $224,928 three-year Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), will fund collaborative research on adaptations of Southern Ocean diatoms to manganese scarcity. The University of Georgia Research Foundation will support two early career scientists and one female Earth scientist to conduct culture experiments on three Antarctic and one temperate diatom species. Using physiological,...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $298,228 Project Grant to the University of North Carolina at Chapel Hill (UNC) under the Geosciences (CFDA 47.050) federal grant program. This two-year grant funds research to investigate how marine diatoms use proton-pumping rhodopsins as an alternative energy source under conditions of high light and low iron that hinder photosynthesis. The research aims to provide insight on how diatoms, which are responsible for a...
The National Science Foundation Division of Ocean Sciences awarded a $438,331 project grant to the University of Massachusetts Dartmouth under the Geosciences program (CFDA 47.050) to conduct collaborative research from April 1, 2023 through March 31, 2026. The research aims to characterize amino acid nitrogen isotopes in phytoplankton and advance understanding of isotopic patterns produced under varying physiological conditions. Investigators and students will explore how different...
This $918,053 Project Grant award from the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) supports fundamental and applied research to document and characterize the diverse communities of marine epizoic diatoms living on endangered marine megafauna. The overall project objectives are to: 1) describe and formally document up to 50 new species of epizoic diatoms; 2) reconstruct the phylogenetic relationships of these diatoms to understand their evolution and...
