2006 EM300 Multibeam Sonar Data from Cruise Hi'ialakai HI-06-04 - Pacific Remote Island Areas
Description
EM300 multibeam data were collected in 15 March to 8 April 2006 aboard NOAA Ship Hi'ialakai at Jarvis Island, Palmyra Island, and Kingman Island in the Central Pacific during cruise HI-06-04. 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. At Jarvis Island, Hilo (1617760) predicted tides were used with a +2.0 time corrector and a range ratio of 1.10. At Palmyra and Kingman, Honolulu (1612340) predicted tides were used with a +1 hr 19 min time corrector and a range ratio of 0.56. Horizontal accuracy is 20m (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 to 3500 m. Concurrent mapping was done by the R/V AHI in water depths ranging from 10-250 m with the data set being AHI-06-04; metadata for AHI-06-04 are submitted separately.
