Bottom coverage was achieved in depths between ~12 and 285 meters, The Arc ASCII grid includes 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. The ASCII grid was 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.

The NOAA Ship Hi'ialakai's survey sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad EM3002d sonar, which provide bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position, velocity, attitude and heading, and a Seabird SBE 9/11 plus CTD used to measure sound velocity profiles. Multibeam data were also collected aboard the R/V AHI (Acoustic Habitat Investigator), a 25' survey launch owned and operated by the NOAA Pacific Islands Fisheries Science Center in Honolulu, HI. The R/V AHI's survey sensors include a 240 kHz RESON 8101-ER sonar providing bathymetry and imagery data, a TSS/Applanix POS/MV Model 320 which measures position, velocity, attitude and heading, and a Seabird SBE 19 CTD used to measure sound velocity profiles. Specific equipment configurations are documented in metadata from cruises AHI0703 and HI0703. These metadata can be accessed at: https://www.soest.hawaii.edu/pibhmc/cms/cruise-catalog/ 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 should be considered to be within 1 meter.

The edited swath files are then combined into a Pure File Magic (PFM) format with a defined grid cell size (5m) in SABER and area based editing is performed. The edited PFM is then exported as X,Y,Z data with a value at each grid node. The X,Y,Z data are then and gridded using nearneighbor, a Generic Mapping Tools (GMT) algorithm that converts an ASCII or binary table to a netCDF grid file format. NetCDF grids are then converted to an ArcGIS ASCII file format using LINUX/UNIX commands in combination with GMT. GMT is an open source collection of tools for manipulating geographic data sets. Additional information about GMT can be found at: http://www.soest.hawaii.edu/gmt and additional information about the multibeam data processing is recorded in the cruise metadata. 2007-10-02T00:00:00 otherRestrictions Metadata Access Constraints: None otherRestrictions Metadata Use Constraints: None annually This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
