Other ID: 88-2-PR

Status: Completed

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

Funding Program(s):

Principal Investigator(s): William Schwab

Affiliate Investigator(s):

Information Specialist(s): William Danforth

Data Type(s): Location-Elevation: Navigation, Sonar: Sidescan, Sonar: Single Beam

Scientific Purpose/Goals: 1. Image area of suspected slope failure using SeaMARC 1B sidescan sonar system. 2. Image the heads of a series of submarine canyons at the north Puerto Rico shelfbreak using the Klein 100 kHz sidescan sonar system.

Vehicle(s):

Start Port/Location: Roosevelt Roads Naval Base, Puerto Rico

End Port/Location: San Juan, Puerto Rico

Start Date: 1988-03-25

End Date: 1988-04-04

Equipment Used: SeaMARC sidescan sonar system, Klein 531 sidescan, Starfix navigation system, 12 kHz

Information to be Derived: Sea floor map;

Summary of Activity and Data Gathered: Cruise terminated early due to loss of SeaMARC 1B on March 29, 1988, and Klein 100 kHz sidescan sonar towfish and cable on April 3, 1988. Data acquired: SeaMARC 1B Sidescan Sonar: 95 km; Klein 100 kHz Sidescan Sonar: 50 km; 12 kHz Bathymetry: 700 km.
