Download Data - Surface Elevation


Surface Elevation data can be downloaded either by project, CRMS (Coastwide Reference Monitoring System) site, or station number. These data are collected at specific locations within herbaceous marsh vegetation areas and forested swamp/bottomland hardwood vegetation areas, and are collected at various time intervals ranging from every 6 months to every two 2-3 years. The sampling parameters consist of several sediment elevation measurements taken relative to a fixed sub-surface datum at each location.
