Multibeam Survey of Humboldt Ocean Disposal Site

April 30, 2015 by eTrac

eTrac completed a multibeam survey of the Humboldt Ocean Disposal site approximately 10 miles offshore. Mulitbeam and snippets data were collected on an R2 2024 down to 400ft to create both bathymetry and backscatter grids. A sediment classification map was created using this data with sediment samples collected across the area.
