Other ID: RB0208

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Uri Ten Brink

Affiliate Investigator(s):

Information Specialist(s): Jennifer Martin

Data Type(s): Environmental Data: CTD, Environmental Data: Temperature, Imagery: Photo, Sonar: Multibeam

Scientific Purpose/Goals: Multibeam bathymetry of the Puerto Rico trench.

Vehicle(s):

Start Port/Location: San Juan, Puerto Rico

End Port/Location: San Juan, Puerto Rico

Start Date: 2002-09-24

End Date: 2002-09-30

Equipment Used: SeaBeam 2112, SBE 9 CTD, XBT, Digital camera

Information to be Derived: Sea floor map; Bathymetric maps; Morphology;

Summary of Activity and Data Gathered: Multibeam bathymetry and acoustic backscatter data were collected in an area roughly 25,000 km2 in size using SeaBeam 2112 (12 kHz) system mounted on the hull of the NOAA ship RONALD H. BROWN. Onboard tests have established the spatial resolution of the multibeam bathymetry and the backscatter image at this large water depth to be 100-150 m and 30 m, respectively. The vertical resolution could not be established independently from the data, but is thought to be about 0.5% of the water depth.
