Field Activity 09CCT03

Identifier 09CCT03
Alternate names 09CCT03A
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 Cat Island, MS to Dauphin Island, AL
Summary A total of 203 (09CCT03 - 139 lines, 09CCT03A - 64 lines) Chirp 2-D subbottom profiles and 216 (09CCT03 - 146 lines, 09CCT03A - 70 lines) Swath lines were collected and ~50 km of shoreline were surveyed. Note: A subset of the seismic data collected around Cat Island, MS, was informally given the ID of 09CCT03A and consisted of lines 09c627 to 09c695.
Info derived High precision Submetrix swath bathymetry data; shallow sub-bottom image profiles, recent shoreline topography (X, Y, Z).
Comments Additional Equipment: one portable GPS topographic survey buggy.
