NOAA National Estuarine Inventory: Supplement
The estuarine systems selected are from the NOAA National Estuarine Inventory in the North Atlantic region (Figure 1). The principal spatial unit of each system is the estuarine drainage area (EDA) defined in the NEI data atlas (U.S. NOAA, 1985). The sediment distributions embrace the estuarine bottom area, i.e. from the head of tides to the mouth where the estuary meets the ocean, bay or sound as determined by physiographic features (U.S. NOAA, 1985). Data coverage embraces whole estuaries and far-field distributions. Chart scales are smaller than 1:80,000 and chart units larger than 0.06 square kilometer.
