Field Activity 08CCT01

Identifier 08CCT01
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 Ship Island, MS
Info derived Submetrix swath bathymetry data; shallow subbotom image profiles; high precision single beam bathymetry (X, Y, Z)
Comments Additional Equipment: Knudsen 320 bathy profiles
