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 $335,410 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research study led by the Woods Hole Oceanographic Institution (WHOI) to investigate the cycling and uptake of monomethylmercury (MMHg) in natural phytoplankton assemblages. The 3-year study will focus on the Western North Atlantic Ocean and its estuaries, a region with productive fisheries. The research aims to better understand the fundamental processes governing...
The National Science Foundation (NSF) awarded a $574,980 Project Grant under its Geosciences program (CFDA 47.050) to the University of Rhode Island (URI) Research Office Division. The grant will support research to study monomethylmercury (MMHg) in natural phytoplankton assemblages in the western North Atlantic Ocean and its estuaries. The project aims to improve understanding of the fundamental processes governing MMHg uptake and cycling at the base of the marine food web. The researchers will...
The National Science Foundation awarded a $432,778 Project Grant to the University of Connecticut under the Geosciences program (CFDA 47.050) for research titled "Collaborative Research: The Effects of Terrestrial Organic Matter Inputs on Coastal Mercury Cycling, Methylmercury Production and Bioaccumulation." The three-year award beginning June 1, 2022 will support research examining how increased terrestrial organic matter delivery to coastal waters from climate change influences...
The University of Connecticut is conducting a $680,675 project grant awarded by the National Science Foundation's Division of Ocean Sciences under the Geosciences Program (CFDA 47.050) to study the air-sea exchange of inorganic and methylated mercury in the Sargasso Sea. The study aims to evaluate the concentrations of mercury in the surface ocean and atmosphere, examine the factors controlling its chemistry, and quantify the sources and sinks of mercury. Researchers will collect high-resolution...
The University of Connecticut was awarded a $283,534 project grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to study methylated mercury sources and cycling in the high latitude North Atlantic. This two-year award, which began on August 15, 2021 and runs through July 31, 2023, will fund research into strengthening the understanding of the integrated Earth system through basic research of atmospheric, earth, and ocean...
This $401,056 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund research examining the effects of terrestrial organic matter inputs on coastal mercury cycling, methylmercury production and bioaccumulation in the Gulf of Maine. Specifically, the grantee will study how climate change-driven increases in rainfall and river runoff influence the delivery of contaminants, organic matter and nutrients from land to coastal waters. Field surveys and shipboard...
The University of Connecticut received a $549,778 Project Grant award from the National Science Foundation (NSF) Division of Ocean Sciences, under the NSF's Geosciences program (CFDA 47.050), to develop new methods for measuring the balance between nitrogen fixation and denitrification in marine systems. The key products and services to be delivered include: Developing a high-precision, high-throughput method for analyzing noble gases (neon, argon, krypton) along with nitrogen gas, which will...
The University of Utah will receive $345,496 under a two-year Project Grant from the National Science Foundation Division of Earth Sciences through the Geosciences program (CFDA 47.050) to develop new methods for measuring mercury and methylmercury isotopes in high-salinity, high-dissolved organic matter environments. Current methods cannot be used in these conditions, inhibiting understanding of mercury pathways into wildlife. The University will work with the U.S. Geological Survey to devise...
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...
