2007 EM300 and EM3002D Multibeam Sonar Data from Cruise Hi'ialakai HI0701 - Oahu Island and Wake Atoll
Description
EM300 and EM3002D multibeam Data were collected from 19 April - 9 May 2007 aboard NOAA Ship Hi'ialakai at Oahu Island in the Main Hawaiian Islands, and and Wake Atoll during cruise HI0701. 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. Concurrent mapping at Wake Island was done by the R/V AHI in water depths ranging from ~10-350 m with the data set being AHI0701; (metadata for AHI0701 are submitted separately.)
