Name: Bathymetry - Aransas Bay
Display Field:
Type: Raster Layer
Geometry Type: null
Description: Bathymetry for Aransas Bay was derived from fourteen surveys containing 123,235 soundings. The average separation between soundings was 65 meters. Two entire overlapping, older, less accurate surveys were deleted before tinning. The overlap from two older, less accurate surveys was also deleted before tinning. The surveys used dated from 1935 to 1991. Surveys from 1989 to 1991 cover the majority of the bay. The range of soundings for the surveys used was 2.0 to -16.1 meters. A mean high water value of 0.3 meters was assigned to the shoreline. Ten points were found that were not consistent with the surrounding points. These were removed prior to tinning. Aransas Bay has twelve 7.5 minute DEMs and four one degree DEMs.
