Gridded bathymetry shelf, bank and slope environments of Farallon de Pajaros Island (Uracas), CNMI. Bottom coverage was achieved in depths between 4 and 3275 meters, but this 10 m grid contains data to 800 m. The netCDF and Arc ASCII grids include multibeam bathymetry from the Simrad EM300 and Reson 8101 multibeam sonars collected as of June 2007 by the NOAA Coral Reef Ecosystem Division. The sonar frequencies are 30 and 240 kHz respectively.
