Name: Bathymetry - Mississippi Sound

Display Field:

Type: Raster Layer

Geometry Type: null

Description: Bathymetry for Mississippi Sound was derived from thirty-three surveys containing 371,210 soundings. Five overlapping, older, less accurate surveys were omitted before tinning. The average distance between soundings was 89 meters. The thirty-three surveys used dated from 1960 to 1979. The range of soundings for the surveys used was 0.8 meters to -17.6 meters at mean low water. A mean high water value of 0.5 meters was assigned to the shoreline. Twenty-five points were found that were not consistent with the surrounding points. These were removed prior to tinning. Mississippi Sound has forty-four 7.5 minute DEMs and three one degree DEMs.
