This federal Project Grant award of $495,521 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to better understand cold-season hydrological dynamics and lateral carbon export in North Atlantic salt marshes. The key objectives are to: (1) monitor soil temperatures, groundwater, and surface water conditions in four salt marshes between Massachusetts and Nova Scotia to quantify marsh freezing; (2) measure groundwater discharge and its seasonal...
This $499,225 National Science Foundation award under the Geosciences program (CFDA 47.050) will fund a collaborative research project between Old Dominion University Research Foundation and the United States Department of Geological Survey to decipher drivers and variability in salt marsh lateral carbon export. Over three years, the researchers will investigate how elevation within the tidal frame influences dissolved inorganic carbon, total alkalinity, and dissolved organic carbon export...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $351,926 to Yale University to conduct research on the connections between tidal flooding, saltwater intrusion, and alkalinity exports in tidal marsh wetlands. The project will develop a mathematical model combining estuarine physics, hydrological drivers, and biogeochemistry to estimate how much alkalinity is delivered from marshes to the ocean. This research aims to improve...
This $1,651,641 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to study the origin, salinity changes, and biological responses of offshore freshened groundwater found in the continental shelf offshore New England, USA. The project will install sensors in boreholes to collect continuous data on fluid pressure, temperature, and resistivity, which will be used to refine groundwater models and improve understanding of this offshore freshened...
This Project Grant award from the National Science Foundation's Biological Sciences program (CFDA 47.074) provides $468,417 to the University of South Carolina to conduct long-term research on salt marsh primary production. The research builds on decades of prior work in South Carolina's North Inlet area since 1984, and aims to test three new hypotheses: 1) marsh elevation gain is regulated by belowground biomass production, 2) marsh surface elevation change is constrained by primary...
This three-year, $489,998 project grant from the National Science Foundation Division of Ocean Sciences aims to advance understanding of lateral carbon export from salt marshes. Under the Geosciences program (CFDA 47.050), which supports basic research in the atmospheric, earth, and ocean sciences, the Woods Hole Oceanographic Institution will investigate drivers of dissolved inorganic carbon, dissolved organic carbon, and total alkalinity fluxes across six New England marsh sites. Researchers...
The National Science Foundation (NSF) awarded a $523,014 Project Grant under the Geosciences program (CFDA 47.050) to the University of Massachusetts (UMass) to develop computational models of global carbon dioxide (CO2) fluxes from inland waters. The research aims to provide robust, physically-constrained estimates of CO2 emissions from rivers, streams, lakes, and reservoirs by coupling hydrologic and hydraulic routing systems with a stream network CO2 model. The project will validate the...
This federal Project Grant award of $453,714 from the National Science Foundation's Geosciences program (CFDA 47.050) supports a collaborative research project titled "ULTRA-DATA: Synthesizing the Role of Shallow Benthic Fluxes in Coastal Carbon Cycle along the East Coast of the United States." The project aims to improve understanding of the role of coastal seafloor sediments in carbon, oxygen, and nutrient cycling by combining observations, model outputs, and re-analyses for the...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) will provide $334,904 from December 1, 2024 to November 30, 2026 to the Virginia Institute of Marine Science (VIMS) to investigate how the increasing prevalence of weedy seagrass species affects coastal ecosystem functioning and carbon cycling. The key objectives of this research project are to: 1) Assess how seagrass species identity and bivalve functional traits interact to influence...
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...
