North Carolina bathymetry/topography sea level rise project : determination of sea level trends
Filetype[PDF-1.42 MB]

  • Description:
    "NOAA's Center for Sponsored Coastal Ocean Research (CSCOR) recently initiated a program entitled "Ecological Impacts of Sea Level Rise". This program is intended to evaluate the potential impact of long-term sea level rise on a specific coastal region, 25 to 50 years in the future. An initial goal of the project is to generate a digital elevation model (DEM) for the bathymetry and topography of the North Carolina coastal region, with all elevations tied to a common datum. Present-day sea level trends will be extended into the future, raising the tidal datums and thereby shifting the position of the shoreline. For North Carolina, the shoreline is defined as the mean high water (MHW) tidal datum (NOS, 2001). Maps will be generated indicating which low-lying areas of the coastal region will be submerged. A prerequisite for this project is the accurate determination of sea level trends using historic data at as many coastal locations as possible"--Introduction.
