    dct:description "EM300 and EM3002D multibeam Data were collected from 11-31 October 2005 aboard NOAA Ship Hi'ialakai at Maro Reef and a seamount east of Nihoa Island in the Northwestern Hawaiian Islands during cruise HI-05-08. 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 ~30-3000m. Concurrent mapping at Maro Reef was done by the R/V AHI in water depths ranging from 30-100m with the data set being AHI-05-08; metadata for AHI-05-08 are submitted separately." ;
