2006 Reson 8101ER Multibeam Sonar Data from Cruise AHI-06-01 - Pacific Remote Island Areas
Description
Reson 8101ER multibeam Data were collected from 15 Jan - 6 Feb aboard NOAA Survey Launch Acoustic Habitat Investigator (AHI) at Johnston Island, Howland Island, and Baker Island in the Central Pacific during cruise AHI-06-01. 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: for Johnston Island predicted tides from the NOS CO-OPS web site were used; for Baker and Howland Islands predicted tides based upon the Honolulu tide station (1612340) with a time corrector of 3 hrs 48 min and a range ratio of 3.91. 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 Simrad EM300 and EM3002D sonars aboard the ship; metadata for HI- 06-01 are submitted separately.
