Published by Pacific Islands Fisheries Science Center | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 08, 2025 | Last Modified: 2017-11-01T00:00:00.000+00:00
Gridded bathymetry at 60m resolution surrounding Guam Island, Guam U.S. Territory. Bottom coverage was achieved in depths between 0 and ~3500 meters. The Arc ASCII grids and floating point geotifs include multibeam bathymetry data acquired over multiple surveys by the NOAA Pacific Islands Fisheries Science Center, Ecosystem Sciences Division (as of May 2017). The data were acquired using the Simrad EM300, and Reson 8101 multibeam sonars, with sonar frequencies of 30 and 240 kHz respectively. The 60m grid is mosaiced from data sets acquired in 2003, 2007, 2010 and 2017.
