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. | ||||||||
