This Project Grant award for $388,527, provided by the National Science Foundation (NSF) Geosciences Program (CFDA 47.050), supports research on how salt affects the photodegradation of dissolved organic matter (DOM) in aquatic ecosystems. The project, led by Texas A&M University-Corpus Christi (TAMU-CC), will investigate the role of salt in photochemical reactions involving DOM, which plays key ecological roles in energy transfer, metal binding, and interactions with pollutants. Experiments...
This Project Grant award from the National Science Foundation's (NSF) Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will investigate the photochemical breakdown of marine dissolved organic matter (DOM) and its impact on the global carbon cycle. The $683,778 award, valid from July 2023 to June 2026, will focus on studying the production rates and quantum yields of one and two-carbon photoproducts, such as carbon monoxide, dissolved inorganic carbon, formaldehyde, and...
This Project Grant award from the National Science Foundation (NSF) Geosciences program (CFDA 47.050) provides $107,673 to the Regents of the University of Minnesota to study the role of dissolved organic nitrogen (DON) in sustaining biological productivity in the oligotrophic subtropical North Pacific Ocean. The award will fund a one-month research expedition from San Diego, CA to Honolulu, HI to collect observations on DON concentration, composition, and utilization by marine microbes. The...
The Regents of the University of Minnesota were awarded a three-year, $299,017 Project Grant from the National Science Foundation under the Geosciences program (CFDA 47.050). The grant will support collaborative research exploring new roles for reactive oxygen species in mediating carbon fluxes at the terrestrial-aquatic interface. The research aims to strengthen fundamental understanding of the integrated Earth system by expanding knowledge of atmospheric, earth, and ocean sciences processes....
The National Science Foundation (NSF) Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded a $117,303 Project Grant under the Engineering program (CFDA 47.041) to the University of St. Thomas in St. Paul, Minnesota. The grant supports collaborative research to advance the fundamental understanding of how sunlight-induced photochemical degradation processes impact the fate of synthetic organic pollutants like pesticides and pharmaceuticals in surface water systems...
This five-year, $360,743 National Science Foundation project grant funds research and community outreach to advance understanding of freshwater salinization in Wisconsin and globally. Led by the University of Wisconsin-Madison, the project aims to establish a long-term salt observatory in the Yahara watershed to track salt pollution from source to outflow and study impacts on freshwater ecosystems. Researchers will collaborate with community groups to promote awareness of salt impacts and make...
This National Science Foundation (NSF) Geosciences program award, CFDA 47.050, provides $437,806 to the Regents of the University of Minnesota, Office of Sponsored Projects Administration, to conduct collaborative research on the molecular speciation of trace elements like iron, copper, zinc, and manganese in the Southern Ocean and Antarctic continental shelf. The research aims to identify the organic ligands that bind to these biologically essential metals, and determine their sources and...
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...
The University of Wisconsin-Madison received a three-year, $326,446 Project Grant from the National Science Foundation Division of Earth Sciences under the Geosciences program (CFDA 47.050). The grant will fund research from August 2021 through July 2024 to identify the role of dissolved organic matter composition in complete and partial photooxidation in diverse lakes. As part of the Geosciences program's goal to expand understanding of the integrated Earth system through basic research, this...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $346,823 Project Grant to the Regents of the University of Colorado (doing business as the University of Colorado) to conduct research under the NSF Geosciences program (CFDA 47.050). This research project aims to better understand how transformations to microplastics in coastal environments impact their regional-scale transport and fate. The study will use Lagrangian tracers and existing hydrodynamic modeling to quantify...
