Name: Bathymetry - Terrebonne-Timbalier Bays

Display Field:

Type: Raster Layer

Geometry Type: null

Description: Bathymetry for Terrebonne/Timbalier Bays was derived from twelve surveys containing 94,975 soundings. No surveys were omitted. The average separation between soundings was 115 meters. The surveys used dated from 1934 and 1935. The soundings ranged from 0.3 meters to -16.8 meters at mean low water. Mean high water values of 0.4 and 0.5 meters were assigned to the shoreline. Six points were found that were not consistent with the surrounding data. These were removed prior to tinning. Terrebonne/Timbalier Bays have twenty-three 7.5 minute DEMs and two one degree DEMs.
