| Purpose | To create a complete modern topobathymetric map of the Mississippi barrier islands from Cat Island to Dauphin Island. Data to provide information for the following: sediment budget; assessment of immediate sand resources in the region, modern geologic framework; historical island change measurements; base-level assessment of the seafloor since the 2005 hurricane season | ||||||||
| Location | Horn Island, MS to Dauphin Island, AL | ||||||||
| Summary | A total of 192 chirp 2-D sub-bottom profiles, 192 swath, and 102 side scan lines were collected. | ||||||||
| Info derived | Submetrix swath bathymetry data; shallow sub-botom image profiles and, side-scan sonar mosaics | ||||||||
| Comments | Shop Staff (Pre-Cruise) - Dave Wegener contributed 1.5 weeks to design and fabrication; Richard Young was boat captain during 2 days of Side Scan equipment testing. Additional equipment: L3900 Klein Side Scan Towfish. | ||||||||
