Purpose
|
Seafloor mapping to 1] support management of ocean resources,
2] clarify the post-glacial history of sea-level change in the
region, 3] reconstruct coastal environments and quantifying rates of
change over the last few thousand years, and 4] develop a sediment
budget for the coastal system, which is experiencing chronic erosion.

Summary
|
We collected 100% coverage of seafloor with bathymetry and
sidescan sonar data, approximately 1000 km of seismic reflection
profiles, and grab samples and bottom photography/video at 93
stations. Cruise focused on nearshore areas in water depths of 5-25
m to complete the surficial mapping that was begun in 2003 (SAIC
contract multibeam). Subbottom profiles were collected throughout
entire study area in water depths of 5-90 m.

Notes
|
The new remotely operated vehicle (ROV) was deployed for the
first time to successfully recover a sound-velocity profiler that
was lost during a cast.

Got Help?
|
For 05005, we would appreciate any information on -- activity type, analog materials, contract, days at sea, dive count, funding, kms of navigation, national plan, NGDC Info, owner, project number, publications, scanned materials, seismic description, station count, station description, submersible, tabulated info.
