The 3-year project will conduct laboratory experiments to estimate the fluxes of these vital compounds from key bacterial groups and the impacts of temperature changes, which are critical for understanding plankton...
- The National Science Foundation awarded a $410,518 three-year Project Grant to The University of Puget Sound under the Geosciences program (CFDA 47.050) to conduct research on aerobic methane production in ocean environments. The university will collaborate with scientists in the U.S. and Israel to study the microbial processes that produce methane through the degradation of organic compounds in the surface waters of the North Pacific and North Atlantic oceans. Researchers will measure methane...
- This National Science Foundation Project Grant of $597,248 supports research into applying novel approaches to link microbial growth efficiency, function, and energy transfer in the ocean. Funded under the Geosciences program (CFDA 47.050), the award will further understanding of the integrated Earth system through basic research in ocean sciences. Specifically, the University of Miami Rosenstiel School of Marine and Atmospheric Science will conduct research from September 2023 to August 2026 to...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant, awarded to Bigelow Laboratory for Ocean Sciences, provides $158,036 to study monomethylmercury (MMHg) cycling in natural phytoplankton assemblages in the western North Atlantic Ocean. The overarching goal is to improve understanding of the factors controlling MMHg uptake by phytoplankton, which is crucial for modeling MMHg transfer through the marine food web. Key research activities include year-round...
- This $280,627 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research into estuarine metabolism and gas exchange processes. The University of Notre Dame will develop new methods to analyze dissolved oxygen time series data to better quantify key estuarine functions like gross primary production, ecosystem respiration, and gas exchange. Researchers will evaluate advection removal techniques and gas transfer parameterizations through field campaigns...
- The National Science Foundation Division of Ocean Sciences awarded a $296,671 Project Grant to the University of Virginia to develop a novel approach for measuring greenhouse gas emissions from coastal marine ecosystems. The two-year award, made under the Geosciences program (CFDA 47.050), will support the Principal Investigator's research combining upside-down aquatic eddy covariance measurements of oxygen fluxes at the air-water interface with new sensor technologies to extract greenhouse...
This $982,958 Project Grant awarded by the National Science Foundation's Division of Ocean Sciences (CFDA 47.050 Geosciences) supports a research project at the University of North Carolina at Chapel Hill to investigate the role of single-carbon (C1) metabolism, focusing on methane and methanol, in estuarine carbon cycling within the Neuse River Estuary and Pamlico Sound. The overarching goal is to quantify the stocks and oxidation rates of C1 compounds, identify the microbial communities responsible for their turnover, and characterize the physiological traits that influence methanotroph and methylotroph distributions across estuarine gradients. The project aims to improve predictive models of estuarine responses to environmental change and advance the understanding of microbial controls on carbon cycling. The award provides funding for this comprehensive research approach, which integrates spatiotemporally resolved field surveys, laboratory experiments, and the development of a cell-scale reaction-transport model. Additionally, the project supports hands-on research opportunities for graduate, undergraduate, and high school students, training the next generation of environmental microbiologists and biogeochemists.
