Soundings were taken at the prescribed intervals to determine the current condition of the channels. Data was collected in the field utilizing Coastal Oceanographics Hypack Max v. 4.3a software. Collected information was processed and mapped utilizing Coastal Oceanographics Hypack Max 4.3a software, Bentley Microstation V8 and Bentley InRoads SelectCAD v. 8.02. Purpose: To graphically provide bathymetric data for the above referenced channels.
