Purpose
Seafloor mapping along the offshore side of the southern
part of the Chandeleur Islands, Gulf of Mexico
Summary
This two-week cruise aboard the R/V ACADIANA collected
bathymetric, sidescan sonar and chirp seismic data along the
offshore side of the southern half of the Chandeleur Island chain of
eastern Louisiana.  The survey was coordinated with additional
surveys conducted by the R/V GILBERT and a University of New Orleans
vessel that collected bathymetric and seismic data near the islands
and along the back side of the island chain.  The purposes for
collecting these data were (1) to provide a detailed post-Katrina
bathymetry, (2)to study the processes that have shaped the sea floor
in an effort to better understand the effects of hurricane Katrina,
and (3) to understand the influence of the underlying stratigraphy
on the sea floor geology. The offshore geophysical dataset was
collected on a grid of lines spaced 100 m apart in the shore
parallel direction and 1000 m apart in the shore normal direction.
Submetrix swath bathymetric data and Klein sidescan sonar imagery
were collected along 2146 km of tracks and Edgetech 512i chirp
subbottom data were collected along 1654 km of tracks.
