Summary for Field Activity Number 2008-021-FA

Alternate Leg ID: OC 444; O-21-08-NA

Area of Operations: New England continental slope, United States, North America, North Atlantic

Dates: April 18, 2008 to April 24, 2008

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

Type of Activity: Sea floor mapping
Sesimic profiling

Information to be derived:

Summary: 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.
