Other ID: OC 444; O-21-08-NA

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Uri Ten Brink

Affiliate Investigator(s): WHOI

Information Specialist(s): Jason Chaytor, PARTNER

Data Type(s): Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sonar: Single Beam

Scientific Purpose/Goals: Map submarine landslides as part of a WHOI test cruise of the hybrid AUV/ROV SENTRY.

Vehicle(s):

Start Date: 2008-04-18

Start Port/Location: Woods Hole, MA

End Date: 2008-04-24

End Port/Location: Woods Hole, MA

Equipment Used: ROV, GPS (wh), Knudsen echo sounder 320B/R

Information to be Derived:

Summary of Activity and Data Gathered: Using the hull-mounted Knudsen 320B/R deepwater echo sounder on the OCEANUS, approximately 1065 km of 3.5 kHz sub-bottom data were collected over the 6 days of the cruise (see map). Data were acquired in both Knudsen proprietary binary format (.keb) viewable only in the Knudsen 'Post Survey' software and in standard SEG-Y format for later processing. Multibeam data was not collected in the survey area because of technical problems with the RESON multibeam sonar aboard the Sentry.
