This project addressed the needs of coastal managers and restoration practitioners for more information about TLP's effectiveness across diverse marsh plant communities and regions. Researchers conducted coordinated restoration experiments at eight National Estuarine Research Reserves across the East and West Coasts. The team assessed the impact of elevation, sediment type, and layer thickness on the success of this marsh adaptation technique. Greenhouse experiments exploring the effect of sediment texture and the addition of biochar as a soil amendment complemented these field studies. To support future use of TLP, the project team and an advisory committee of coastal managers at state and federal agencies and nonprofit groups created a suite of guidance documents including a consensus statement on thin-layer placement in tidal marsh ecosystems. Tidal marshes provide key ecosystem services, but are threatened by sea level rise. For these ecosystems to survive, it will require active management to increase tidal marsh resilience. Researchers at the Narragansett Bay and Elkhorn Slough National Estuarine Research Reserves recently led the first national assessment of tidal marsh resilience to sea level rise to monitor coastal reserve sites across the continental United States. Now the research team is moving beyond marsh resilience monitoring and assessment to actively test strategies to enhance resilience. This project tested the restoration effectiveness of thin-layer placement, an emergent climate adaptation strategy and one of the only viable strategies to protect tidal marshes in their current footprint. completed notPlanned EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > ESTUARY theme Global Change Master Directory (GCMD) Science Keywords 23.3 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > CALIFORNIA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MARYLAND CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MASSACHUSETTS CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > NEW HAMPSHIRE CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > NORTH CAROLINA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > RHODE ISLAND CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > VIRGINIA place Global Change Master Directory (GCMD) Location Keywords 23.3 Chesapeake Bay NERR, MD Chesapeake Bay NERR, VA Elkhorn Slough NERR, CA Great Bay NERR, NH Narragansett Bay NERR, RI North Carolina NERR, NC San Francisco NERR, CA Waquoit Bay NERR, MA place DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
