Reson 8101ER multibeam Data were collected from 23 June to 19 July 2006 aboard NOAA Survey Launch Acoustic Habitat Investigator (AHI) at Kure Atoll, Pearl and Hermes Atoll, and Kaua'i Island in the Central Pacific during cruise HI-06-09. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Sound velocity corrections from a Seabird SBE19 CTD sensor and motion corrections from a POS-MV vertical reference were applied to the data in real time. Predicted tides were applied to the data in real time using tide zoning and predicted tides supplied by NOAA's National Ocean Service Center for Operational Oceanographic Products and Services (CO-OPS). At Kure Atoll, Sand Island (1619910) predicted tides were used in zone HI48. At Pearl and Hermes Atoll, Sand Island (1619910) predicted tides were used in zones HI46 and HI47. At Kauai Island, Nawiliwili (1611400) predicted tides were used in zones HI137, HI138, and HI139. Horizontal accuracy is 20m (no differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation. Depths mapped range from 10 - 300 m. The AHI was deployed from the NOAA Ship Hi'ialakai and concurrent mapping was done using the Simrad EM300 and EM3002D sonars aboard the ship; metadata for HI-06-09 are submitted separately.
