This includes the delineation of sand/mud bottom, artificial reef, boulder field, cobble, and reef ledge. The previously stated features were delineated using side scan sonar signatures that were acquired using a side scan towfish. The side scan sonar was then processed in SonarWiz 7.2 to produce the initial imagery for interpretation, and then brought into ArcGIS Pro for actual feature digitization. CSA Ocean Sciences, Inc.
