EM300 and EM3002D multibeam Data were collected in 14 May-7 June 2005 aboard NOAA Ship Hi'ialakai at French Frigate Shoals, Maro Reef, Pearl and Hermes Reef, Midway Island, and Kure Atoll in the Northwestern Hawaiian Islands during cruise HI-05-03. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Surface sound velocity values were supplied by a Seabird SBE-45 MicroTSG and a SBE-38 remote temperature probe. Sound velocity corrections from a Seabird 911 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. Horizontal accuracy is 20 m (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 ~20-3000 m.
