10CCT03 (CMHRP activity #209)

Field Activity 10CCT03

Identifier

10CCT03

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

Geophysical data including side scan sonar, bathymetry and sub-bottom profiles were successfully acquired during this survey.

Info derived

Submetrix swath bathymetry data; shallow sub-bottom image profiles, sediment thickness and side-scan sonar mosaics

Comments

Additional Equipment: L3900 Klein Side Scan Towfish (USGS); Multibeam RESON SeaBat 8125 (USACE) and DGPS‚ Applanix POS MV (USACE).
