A total of 74 sites were surveyed across four different salinity zones (fresh, intermediate, brackish, saline). At most sites, measurements were taken at the edge (1-3m from the actual marsh edge with the open water), and in the interior (20-25 m from the edge). At each site (both edge and interior), ten vertical profiles (every 10 cm, up to 55 cm depth) of soil strength were collected. Marsh strength was measured with a Humboldt “field vane shear set” (vane size 25.4 x 50.7mm). Marsh elevation was measured with an RTK GPS. Plant type was determined by visual inspection, according to the Daubenmire cover-class method. Soil dry bulk density and organic content was measured in the lab, based on one core taken at each site (both edge and interior). An excel spreadsheet is included with tabs representing data from each experiment or sample type with a README tab with more information on each. Missing values are where a measurement was not taken and should be treated as NaN. The project was aimed to better understand marsh strength as a function of marsh type (salinity), and how that controls marsh edge erodibility. This study was supported by the U.S. Department of the Treasury through the Louisiana Coastal Protection and Restoration Authority’s Center of Excellence Research Grants Program under the Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act of 2012 (RESTORE Act) (Award No. 1 RCEGR260007-01-00). 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:0292959 Preview graphic PNG 0292959 NCEI ACCESSION NUMBER 2024-05-13 publication CORE - BULK DENSITY ORGANIC MATTER - WEIGHT PERCENT PLANT COVER theme NODC DATA TYPES THESAURUS GPS sediment sampler - grab visual estimate instrument NODC INSTRUMENT TYPES THESAURUS in situ laboratory analyses theme NODC OBSERVATION TYPES THESAURUS Louisiana State University dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS Louisiana State University dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Coastal Waters of Gulf of Mexico Coastal Waters of Louisiana place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication Louisiana Coastal Protection and Restoration Authority’s Center of Excellence Research Grants Program (RESTORE Act) project Provider Project Names EARTH SCIENCE > OCEANS > OCEAN CHEMISTRY > ORGANIC MATTER theme Global Change Master Directory (GCMD) Science Keywords 2026 revision 24 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.
