The netCDF and Arc ASCII grids include multibeam bathymetry from the Reson SeaBat 8125 multibeam sonar collected in 2008 by the NOAA Office of Coast Survey and the United States Navy Fleet Survey Team. The sonar frequency is 455 kHz and the data are gridded at 1 m resolution. The data served here were extracted from a Caris project provided by OCS and converted to netCDF and Arc ASCII grids by the NOAA Coral Reef Ecosystem Division. These data were collected in response to a request by the USN for a cooperative modern hydrographic survey with NOAA to provide contemporary hydrographic data to update the nautical charts in the area. The USN plans to use Apra Harbor, Guam as a primary port-of-call. These data will support safe navigation for the USN fleet in Apra Harbor by providing IHO Order 1 hydrography. They will also aid in ongoing habitat mapping efforts by NOAA PIFSC CRED. These netCDF and ASCII grids were created using data gathered from multibeam soundings for use as a planning and reference document. The data are also being used for benthic habitat mapping, for locating Essential Fish Habitat, and for studying geologic features of the area. Refer to supplemental information for description of instrument and survey.

A Reson 8125 multibeam echosounder was mounted from an arm on the port side of the vessel. The Klein 3000 Side Scan Sonar is operated in the stern-towed configuration. Additional detailed information on data acquisition, equipment configuration, and corrections can be found in the Data Acquisition and Processing Report (DAPR), SWAMPFOX_DAPR_2008.pdf, that can be accessed at: www.soest.hawaii.edu/pibhmc and is included in the ZIP file containing the bathymetry grids. Vertical_Coordinate_System_Definition Depth_System_Definition Entity and Attribute Overview: Depth values are real values based on the average of the soundings that fell within the extracted grid cells. The number of soundings per grid cell range from >1000 soundings in shallow depths to as few as 20 soundings in deeper areas. A total error budget for these data have not been developed. Therefore, the accuracy of depth measurements is reported in the DAPR.
