The data were collected for the purpose of quantifying the extent to which the mature project reflected the intended design over time. The data collected for assessment is stored in one .csv file. The .csv file contains gps data (lat, long, and elevation), vegetation data (relative species abundances) and sediment bulk density characterizations from 80 fixed monitoring locations. The fixed monitoring plots were distributed in a stratified random design that was intended to provide equal sampling of each of the created habitat types (low elevation regularly flooded marsh [L], high elevation irregularly flood marsh [H], dune [D], and transitional habitat between dune and high marsh [T]. All fixed plots were visited annually from 2020-2023. This spreadsheet also includes pre-restoration data (coordinates, vegetative species present, and sediment bulk density) at multiple locations across the island. The pre-restoration data was collected in 2018. These data document changes in elevation and vegetative community composition and cover after the island was amended with dredged sediments. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0304076 Preview graphic PNG 0304076 NCEI ACCESSION NUMBER 2025-04-04 publication biological data Canopy Characteristics CORE - BULK DENSITY LATITUDE LONGITUDE SEDIMENTS species abundance SPECIES IDENTIFICATION Vegetation Cover theme NODC DATA TYPES THESAURUS GPS sediment sampler - grab instrument NODC INSTRUMENT TYPES THESAURUS imagery in situ laboratory analyses theme NODC OBSERVATION TYPES THESAURUS NOAA National Centers for Coastal Ocean Science dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA National Centers for Coastal Ocean Science dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Chesapeake Bay place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NOS/NCCOS > National Centers for Coastal Ocean Science, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 23 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
