End Port/Location: San Juan, Puerto Rico
Equipment Used: SeaBeam 2112, SBE 9 CTD, XBT, Digital camera

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.
