EM300 and EM3002D Multibeam Sonar Data from Cruise Hi'ialakai HI-06-05 - Main Hawaiian Islands
Description
EM300 and EM3002D multibeam Data were collected on 19-24 April, and 28 April - 11 May 2006 aboard NOAA Ship Hi'ialakai in the Main Hawaiian Islands at Penguin Bank, N. Shore Molokai, Lanai, and the Big Island of Hawaii during cruise HI-06-05. 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 during post-processing. 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 20-2000 m. Concurrent mapping was done by the R/V AHI in water depths ranging from 10-300 m with the data set being AHI-06-05; metadata for AHI-06-05 are submitted separately.
