This Project Grant award from the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) provides $285,400.00 to the University of Massachusetts to conduct collaborative research on the contribution of wetlands and floodplains to greenhouse gas emissions from streams and rivers. The goal is to determine the types of wetlands and floodplains that add the most CO2 to adjacent waterways, and under what conditions. The project includes a combination of modeling and field...
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 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...
The National Science Foundation (NSF) awarded a $769,637 Project Grant under the Biological Sciences program (CFDA 47.074) to the Smithsonian Institution, doing business as the Office of Sponsored Projects, for a 5-year collaborative research project. The project aims to study spatial and temporal patterns of carbon dioxide and methane emissions across tropical wetland ecosystems in the Brazilian savanna (Cerrado). Researchers will collect high-resolution field data on greenhouse gas fluxes,...
This National Science Foundation (NSF) Project Grant under the Biological Sciences program (CFDA 47.074) will leverage a planned ecosystem-scale herbicide application in the lower Connecticut River to investigate the effects of the invasive aquatic plant hydrilla on carbon cycling and greenhouse gas emissions. The overarching goal is to understand how this invasive species can alter freshwater ecosystem function, with potential linkages to climate change. The $196,466 award to Michigan State...
This $372,598 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to incorporate stream biogeochemistry into carbon assessment models for enhanced rock weathering, a carbon dioxide removal approach. The project aims to add biological processes like photosynthesis and respiration into a dynamic river network model to better quantify the fate of bicarbonate generated through enhanced rock weathering. This will help identify river...
Colorado State University was awarded a $199,724 Project Grant from the National Science Foundation under the Geosciences program (CFDA 47.050) for the period of July 1, 2021 through June 30, 2024. The grant will support collaborative research examining new roles for reactive oxygen species in mediating carbon fluxes at the terrestrial-aquatic interface. Specifically, the funding will enable investigation of how reactive oxygen species produced during microbial decomposition in soils 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...
The University of Massachusetts will receive $368,508 from the National Science Foundation under a three-year Project Grant award to study stream corridor hydrologic controls on carbon dioxide fluxes. The research, to be conducted from July 2021 through June 2024 in Hadley, Massachusetts, aims to strengthen fundamental knowledge of the integrated Earth system through supporting basic research in atmospheric, earth, and ocean sciences. Specifically, the university will examine how hydrologic...
This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) supports research by Boise State University to investigate how microbial activity and fluid flow dynamics in river sediments influence the production and emission of the potent greenhouse gas nitrous oxide. The $189,234 award will fund experiments and numerical simulations to determine the spatial and temporal patterns of low-oxygen microzones that facilitate nitrous oxide generation. This work aims...
