The Office of National Marine Sanctuaries manages a system of sanctuaries and other managed areas around the country. The legal boundaries of These sanctuaries are defined within the Code of Federal Regulations, at 15 C.F.R. Part 922 and the subparts for each national marine sanctuary. The GIS compatible digital boundary files for each national marine sanctuary are representations of those legal boundaries and are based on the best available data. These files are available for public use at locations defined in this metadata record.

A multibeam backscatter image (0-35 m water depths) mosaiced from hydrographic data collected during a July/August 2002seafloor survey. A Reson 8101 multibeam echosounder (240 kHz) was pole mounted to the bow of a California State University Monterey Bay survey launch to acquire the sonar data. A TSS POS/MV was used to compensate for vessel motion and a Seabird SVP19 plus was used to measure sound speed. Navigation and line planning were accomplished using Hypack software. Sonar packets, motion sensor, and navigation data were logged in Isis Sonar as XTF files.

A multibeam backscatter image (0-35 m water depths) mosaiced from hydrographic data collected during a August/September 2003seafloor survey. A Reson 8101 multibeam echosounder (240 kHz) was hull mounted to NOAAS Rainier survey launch Ra3 to acquire the sonar data. A Applanix POS/MV was used to compensate for vessel motion and a Seabird SVP 19 plus was used to measure sound speed. Navigation and line planning were accomplished using Hypack software using a CSI wireless DPGS. Sonar packets, motion sensor, and navigation data were logged in Isis Sonar as XTF files.

This side scan sonar imagery of the sea floor (40-100 m water depths) was mosaiced from acoustic data collected in 2002 aboard the NOAA ship McArthur. A Klein System 3000 dual frequency side scan system was used for geophysical surveying, using only the100Khz data to create the mosaic. Isis Sonar (Triton Imaging International) was used to log the digital sonar packets. Sonar data were captured using the 150m range scale setting.

This side scan sonar imagery of the sea floor (120-350 m water depths) was mosaiced from acoustic data collected in 2004 aboard the NOAA ship McArthurII. A Klein System 3000 dual frequency side scan system was used for geophysical surveying, using only the 100Khz data to create the mosaic. A Trimble DSM212Ldifferential GPS was used for towfish positioning. Navigation from the GPS was logged in Hypack Max. Isis Sonar (Triton Imaging International) was used to log the digital sonar packets and cable counter data. Sonar data were captured using the 300m range scale setting.
