- This National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) Project Grant award of $240,000 provides funding for a 3-year postdoctoral research fellowship to study the dynamics of the marsh-forest ecotone in the Chesapeake Bay region. The key objectives are to: Employ remote sensing techniques to track the migration rates of the leading and lagging edges of the marsh-forest ecotone. Use vegetation monitoring to explore how plant communities respond to varying migration...
- 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 Division of Environmental Biology awarded $350,698 under the Biological Sciences (CFDA 47.074) federal grant program to The Marine Biological Laboratory of Woods Hole, Falmouth, Massachusetts. This three-year Project Grant will support collaborative research quantifying the effects of different nitrogen forms on salt marsh resilience to environmental change. Specifically, the research team will conduct paired nutrient enrichment experiments across two coastal...
- The National Science Foundation (NSF) Division of Earth Sciences awarded a $383,646 Project Grant to Rutgers, The State University of New Jersey to conduct collaborative research on hydrogeophysical monitoring and modeling of soil salinization processes in coastal transition zones. The research aims to improve understanding of how subsurface heterogeneity regulates gradual and rapid saltwater intrusion driven by climate change and sea level rise. Key project activities include: Applying...
- This $329,272 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund research to investigate the impacts of sea level rise on stemflow dynamics and associated hydrological and biogeochemical processes in coastal forests along the Atlantic seaboard. The University of Delaware, as the prime awardee, will use field measurements, laboratory analyses, and statistical modeling to understand how changes in stemflow (precipitation channeled down tree...
- 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...
- Federal Grant Award Summary The National Science Foundation (NSF) Division of Environmental Biology awarded $391,583 under the Biological Sciences (CFDA 47.074) program to the University of Maryland, College Park for a collaborative research project spanning January 1, 2026 through December 31, 2030. This project, conducted in partnership with Towson University and the National Audubon Society's "Marshes for Tomorrow" initiative, will investigate whether habitat restoration...
LTREB: LONG TERM STUDIES OF SALT MARSH PRIMARY PRODUCTION -THIS PROPOSAL BUILDS UPON DECADES OF RESEARCH ON SALT MARSH PRIMARY PRODUCTION INITIATED IN NORTH INLET, SC, SINCE 1984. THE RESEARCH INCLUDES MONTHLY NONDESTRUCTIVE MEASUREMENTS OF MARSH CORDGRASS (SPARTINA ALTERNIFLORA) POPULATIONS AND MONTHLY ASSESSMENTS OF SOIL CHEMISTRY AND MARSH SURFACE ELEVATION. THIS LONG-TERM RESEARCH HAS UNCOVERED FUNDAMENTAL INSIGHTS INTO HOW SALT MARSHES FORM, CHANGE OVER TIME, AND SUPPORT OTHER LIFE, AND HAS RESHAPED OUR UNDERSTANDING OF COASTAL WETLAND STABILITY AND REGULATION OF MARSH PRIMARY PRODUCTION. THIS RESEARCH LED TO DEVELOPMENT OF MARSH EQUILIBRIUM THEORY, WHICH EXPLAINS HOW SALTMARSHES MAINTAIN STABILITY AND FORECASTS THE SURVIVAL OF SALTMARSHES IN THE FACE OF CHANGING SEA LEVELS. THIS INFORMATION IS VITAL FOR UNDERSTANDING AND PLANNING FOR THE CONSEQUENCES OF RISING SEA LEVEL ON COASTAL MARINE RESOURCES SUCH AS FISHERIES AND COASTAL INFRASTRUCTURE. CONTINUING FROM EXISTING CORE DATA AND MODELING EFFORTS, THIS PROJECT AIMS TO TEST THREE NEW HYPOTHESES: 1) MARSH ELEVATION GAIN IS REGULATED BY THE PRODUCTION OF BELOWGROUND BIOMASS AND IS PROPORTIONAL TO THE NET PRODUCTION OF THE MARSH ECOSYSTEM; 2) THE RATE OF CHANGE OF THE ELEVATION OF THE MARSH SURFACE IS CONSTRAINED BY PRIMARY PRODUCTION RATES AND THE DECOMPOSITION OF SOIL ORGANIC MATTER, AND 3) MINERAL DEPOSITION AT THE LOWER SALTMARSH EDGE INCREASES WITH ACCELERATING SEA-LEVEL RISE WHILE PRIMARY PRODUCTION DECLINES. THESE INVESTIGATIONS WILL INCLUDE MEASURING DECOMPOSITION RATES OF BELOWGROUND BIOMASS, ANALYZING DNA AND RNA FROM DECOMPOSING PLANT TISSUE FOR MICROBIAL ACTIVITIES, AND QUANTIFYING MINERAL DEPOSITION ACROSS MARSH SURFACES. FIELDWORK WILL INVOLVE SEDIMENT CORE SAMPLING AND PRECISE ELEVATION MEASUREMENTS, CORRELATING THESE WITH BIOMASS AND ENVIRONMENTAL FACTORS. THIS PROJECT SERVES AS A TRAINING GROUND FOR STUDENTS AND FOSTERS INTERDISCIPLINARY RESEARCH. EDUCATIONAL OUTREACH INCLUDES ENGAGING CIVIC AND K-12 GROUPS ON MARSH ECOLOGY AND CLIMATE CHANGE THROUGH PRESENTATIONS AND EXHIBITS AT THE HOBCAW BARONY DISCOVERY CENTER, IMPACTING OVER 16,000 ANNUAL VISITORS. THIS AWARD REFLECTS NSF'S STATUTORY MISSION AND HAS BEEN DEEMED WORTHY OF SUPPORT THROUGH EVALUATION USING THE FOUNDATION'S INTELLECTUAL MERIT AND BROADER IMPACTS REVIEW CRITERIA.- SUBAWARDS ARE NOT PLANNED FOR THIS AWARD.
