2006 Reson 8101ER Multibeam Sonar Data from Cruise AHI-06-04 - Pacific Remote Island Areas
Description
Reson 8101ER multibeam Data were collected in 15 March to 8 April 2006 aboard NOAA Survey Launch Acoustic Habitat Investigator (AHI) at Jarvis Island, Palmyra, Island, and Kingman Island in the Central Pacific during cruise AHI-06-04. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Sound velocity corrections from a Seabird SBE19 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 10 - 300 m. The AHI was deployed from the NOAA Ship Hi'ialakai and concurrent mapping was done using the Simrad EM300 sonars aboard the ship; metadata for HI-06-04 are submitted separately.
