Name: Bathymetry - Perdido Bay
Display Field:
Type: Raster Layer
Geometry Type: null
Description: Bathymetry for Perdido Bay was derived from ten surveys containing 31,436 soundings. Four older, less accurate, overlapping surveys were omitted. The average separation between soundings was 63 meters. The ten surveys used dated from 1935 to 1983. The northern portion of the bay was covered by three surveys from 1935. The southern portion of the bay was covered by seven surveys from 1981 to 1983. The range of soundings for the ten surveys was 0.1 meters to -18.7 meters at mean low water. A mean high water value of 0.3 meters was assigned to the shoreline. Three points were found that were not consistent with the surrounding points. These were removed prior to tinning. Perdido Bay has four 7.5 minute DEMs and a single one degree DEM.
