Key objectives include assessing and advancing...
This three-year $292,300 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research to advance understanding of estuarine transport processes through a Lagrangian framework. Principal investigators from Rutgers, The State University will examine transport of buoyant material in estuaries, specifically the Delaware Estuary, including its aggregation within estuaries and the effects of resulting patchiness on transport. Researchers will address...
This $274,917 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to enhance understanding of the dynamics and response of low-inflow estuaries to increasing aridification and extreme weather events. The primary goals are to develop numerical simulations of low-inflow estuaries using the ROMS hydrodynamical model, evaluate the circulation response to climate-driven changes in surface thermodynamic forcing and freshwater pulses, and...
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 $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 National Science Foundation awarded a $244,878 project grant to the University of Delaware to support collaborative research titled "New Roles for Reactive Oxygen Species in Mediating Carbon Fluxes at the Terrestrial-Aquatic Interface." The three-year award runs from July 1, 2021 to June 30, 2024 under the NSF's Geosciences program (CFDA 47.050). This program aims to strengthen the national scientific enterprise through expanded fundamental knowledge and understanding of Earth's...
The University of Maryland Center for Environmental Science received a three-year, $1,097,772 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences program (CFDA 47.050). The grant will support research examining estuary plumes as drivers of inner continental shelf benthic community structure and function from March 2021 through February 2024. The Geosciences program seeks to expand fundamental knowledge and understanding of Earth's integrated system...
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 $406,274 Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research examining submesoscale frontal dynamics and exchange processes in San Luis Obispo Bay, California. The University of California Santa Cruz will conduct high-resolution measurements of turbulent mixing using ship surveys, moorings, and hydrographic profiling to study how persistent thermal fronts are generated and dissipated downstream of...
The National Science Foundation awarded the University of South Carolina a $844,365 Project Grant under the Geosciences federal grant program (CFDA 47.050) from July 2023 through June 2026. The grant funds collaborative research to quantify the contribution of benthic microalgae to total ecosystem primary production and net primary productivity in the North Inlet Estuary, South Carolina. Researchers will measure benthic microalgal net primary productivity, biomass, community composition and...
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 in two contrasting estuaries. They will also create an Estuarine Bayesian Single-Station Estimation model and apply it to field data and 16 long-term National Estuarine Research Reserve System monitoring sites. Results will enhance understanding of drivers of seasonal and cross-system variability in estuarine metabolism and gas exchange. Broader impacts include educational materials and software for teachers and students, and engaging a high school teacher in the research experience.
