Purpose
High-resolution seismic, swath bathymetry, and sidescan sonar mapping
of the inner shelf off the Mississippi Barrier islands to map the geologic
framework and assess the extent of offshore sand deposits.
Information to be Derived
Sea floor map;Bathymetric maps;Morphology;Stratigraphy
Summary
A cruise aboard the R/V Tommy Munro was conducted March 1-17, 2010 by
the Woods Hole Science Center.  The purpose of the cruise was to collect
swath bathymetry, sidescan sonar imagery and high-resolution chirp seismic
profiles to define the sea floor morphology and the shallow stratigraphy
of the inner shelf offshore of a string of barrier islands in the northern
Gulf of Mexico along the Mississippi coast.  The scientific goals of the
project were twofold: 1) to better understand the geologic evolution of
this coastal region, and 2) to provide stratigraphic information to the
U.S. Army Corps of Engineers for an assessment of sand resources that they
are compiling for the region.
The cruise was hampered by less-than-ideal weather conditions.  Data were
collected during the following days: 3-9 March, 11-12 March, 14-16 March.
During the cruise seismic data were collected along 1778 km of survey
tracklines, swath bathymetry along 1418 km of survey tracklines, and
sidescan imagery along 1332 km of survey tracklines.  Preliminary
processing was completed in the field on all three data types.  The
quality of the chirp and bathymetry data was excellent.  During the
initial part of the cruise, the sidescan imagery was of inferior quality
because of ship noise.  The location of the sidescan vehicle was moved
from the port side to the stern of the ship during the first port call,
and the quality improved significantly.  For the lower quality imagery,
processing procedures were modified to minimize the ship noise.
