    • Marsh surface elevation and accretion datasets for coastal NPS marshes in the northeast U.S.: Trend Analyses for Northeast Coastal and Barrier (NCBN), Northeast Temperate Network (NETN) and National Capital Region Network (NCRN) Network Parks

    Metadata Updated: December 13, 2025

    Tabular datasets in text format (.CSV) containing data on marsh surface elevation, accretion, and sampling station information. The datasets were used in a custom R Package (https://irma.nps.gov/DataStore/Reference/Profile/2296626) containing code, data, and documentation to:

    • Determine trends for each Sampling Station, Site and Park using a GLMM or GAMM based on elevation and accretion data over the full length of the dataset. • Compare elevation and accretion trends to each other for each Sampling Station and Site, as well as to local rates of sea level rise (SLR), • Provide guidance based for when to consider analyzing the SET dataset over shorter time periods, as well as compare accretion and elevation linear trends based on fall and spring sampling dates to determine if sampling frequency can be limited to once per year.
