Purpose
The objectives of this cruise were to map the seafloor and
shallow stratigraphy along the offshore side of the Chandeleur
Islands off the eastern side of the Mississippi delta.  This survey
was done in collaboration with the USGS (St. Petersburg) and the
Univ. of New Orleans who conducted geophysical surveys closer to
shore than could be reached aboard the ACADIANA and along the back
of the Chandeleur Islands.  The reason for the mapping was to assess
the effect of Hurricane Katrina oon the seafloor surrounding these
islands.

Summary
The Chandeleur Islands were severely damaged by Hurricanes
Katrina and Rita, and the goal of this cruise was to map the inner
shelf offshore of the northern part of the island chain to assess
the impact of these hurricanes on the inner shelf.  The survey
covered an area approximately 5 km wide by 46 km long that sharted
in water depths as shallow as 4.5m and ended in water depths
reaching 16 m.  A series of shore parrallel lines spaced
approximately 150 m apart were complimented with a set of
on-offshore lines spaced about 1 km apart.  Sidescan sonar imagery,
interferometric bathymetry and Chirp subbottom profiles were
collected along all survey lines.  The shore-parallel lines were
spaced to provide continuous sidescan sonar coverage, and about 50%
bathymetric coverage.  All data were logged digitally, and were
archived to DVD-ROM prior to the end of the cruise.  Geophysical and
navigation data were collected along 1877 km of survey lines.
Notes
Navigation technique: GPS.
11 days at sea. 1877 km kms. of continuous data. no stations occupied.
Funding
USGS Katrina Supplemental funds
