2005 EM300 and EM3002D Multibeam Sonar Data from Cruise Hi'ialakai HI-05-04 - Main Hawaiian Islands
Description
EM300 and EM3002D multibeam Data were collected from 13 June-08 July 2005 aboard NOAA Ship Hi'ialakai at Niihau, Penguin Bank, and Molokai in the Main Hawaiian Islands during cruise HI-05-04. 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 and observed tides were applied in postprocessing. Horizontal accuracy is 5 m (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 ~20-600m. Concurrent mapping at Niihau, Penguin Bank, and Molokai was done by the R/V AHI in water depths ranging from ~10-150m with the data set being AHI-05-04; metadata for AHI-05-04 are submitted separately.
