Summary Information for Field Activity 2002-051-FA

Area of Operations: Puerto Rico Trench, Puerto Rico, United States, Caribbean Sea, North America, North Atlantic

Dates: September 24, 2002 to September 30, 2002

Chief scientist: Uri ten Brink

Objectives: Multibeam bathymetry of the Puerto Rico trench.

Type of Activity: Sea floor mapping;Sea floor mapping

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

Summary: 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.
