2006 Reson 8101ER Multibeam Sonar Data from Cruise AHI-06-02 - American Samoa

Description

Reson 8101ER multibeam Data were collected in 10-13 Feb. and 18 Feb-13 Mar 2006 aboard NOAA Survey Launch Acoustic Habitat Investigator (AHI) in America Samoa at Swains Island, Tutuila and Rose Atoll during cruise AHI-06-02. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER 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 Tutuila, Pago Pago (170000) predicted tides were used with no corrections; at Rose Atoll, Pago Pago tides were used with +0.1 hr time correction and a range ratio of 0.92; and at Swains Island, Pago Pago predicted tides were used with a -0.5 hr time correction and a 1.12 range ratio. 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 1 - 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-06-02 are submitted separately.
