Sediment Characterization Of Southern New England Systems, The Hudson And Delaware Estuaries, Virginian Province, Maynard M. Nichols, Caroline Brouwer-Riel, Et Al

Reports

The estuarine systems selected are from the NOAA National Estuarine Inventory in the EMAP Virginian Province (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 and contaminant 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 farfield distributions. Chart scales are smaller than 1:80,000 and the minimum mappable unit is 1.0 km2 or larger …
