Project Grant 2342332
- The National Science Foundation (NSF) awarded a $452,705 project grant under the Geosciences program (CFDA 47.050) to the Regents of the University of Minnesota, Duluth. The grant will fund a 3-year collaborative research project to investigate how salt affects the photodegradation of dissolved organic matter (DOM) in aquatic environments. The research will examine the role of carboxyl groups in DOM structure and their interactions with salt ions under sunlight exposure. The study will compare...
- 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 $419,968 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research effort to examine the biogeochemistry of dissolved organic sulfur (DOS) in the Pacific Ocean. The project aims to accurately quantify the DOS inventory across the Pacific, determine the specific compounds that comprise DOS, and investigate the critical roles DOS plays in oceanic and atmospheric processes. The research will utilize archived samples...
- 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 $224,827 Project Grant awarded by the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) will support collaborative research at Virginia Polytechnic Institute & State University (Virginia Tech) to quantify how salinization impacts carbon processing across terrestrial-aquatic boundaries. The key objectives are to: 1) measure field relationships between soil and stream chemistry across a salinity gradient, 2) experimentally determine how soil salinization...
- This $503,649 Project Grant was awarded by the National Science Foundation (NSF) under the Biological Sciences program (CFDA 47.074) to the Division of Agriculture of the University of Arkansas. The project aims to quantify how salinization, which can subsidize or stress organisms, alters carbon processing across terrestrial-aquatic boundaries. Key activities include: Measuring field relationships between terrestrial and stream ecosystems across a salinization gradient through a decomposition...
- This $249,742 Project Grant awarded by the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) supports research by Portland State University to model the impacts of salt stress on coupled carbon and water dynamics in dryland critical zones. The key products and services to be delivered under this grant include: Conducting controlled greenhouse experiments and developing models to understand how factors like root/shoot water and salt storage, plant salt uptake, and...
- The National Science Foundation (NSF) Division of Ocean Sciences awarded a $213,648 project grant to Texas A&M University under the Geosciences (CFDA 47.050) federal grant program. The grant supports a collaborative research project to study how changes in freshwater runoff affect the production and consumption of alkalinity, or acid-neutralizing capacity, in sediments of estuaries along the northwestern Gulf of Mexico. The project will examine three estuaries with varying freshwater inputs,...
- This $283,615 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) supports research at Coastal Carolina University to study the fate of nitrogen in amino acids and the processes that contribute to the formation of refractory dissolved organic nitrogen (DON) in the ocean. Using stable isotope probing with 15N-labeled amino acids, the research team will trace the transformation of different amino acids into inorganic forms, labile DON, and refractory DON...
- This Project Grant award, totaling $364,678.00, was provided by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050). The funding will support a collaborative research project investigating how submarine groundwater discharge delivers dissolved organic nitrogen (DON) and iron to the coastal ecosystem of the West Florida Shelf. The research team, led by Texas A&M University, will quantify the flux and isotopic signatures of this groundwater-derived DON and iron,...
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 will be conducted using freshwater samples from a river-to-marine transect, measuring DOM loss and chemical structure changes under different salt levels and solar exposure. The findings will help predict the effects of increasing salinity, due to climate change and human activities, on DOM's environmental impacts. This 3-year project will provide training opportunities for graduate and undergraduate students, and the results will be shared through publications, presentations, and public outreach activities.
