Cruise ID: RR1301
Multibeam System: EM124/Seapath 380
Dates: January 21-23, 2013
The accuracy (repeatability, strictly speaking) analysis indicates that the system is performing within expected levels. The EM122 appears to be configured correctly and adequately calibrated. A full patch test calibration was conducted with the offsets being applied in SIS; follow up confirmation calibrations indicate that the offsets are correct. A residual bias exists in the system that is associated with the multibeam system itself and not the MRUs (as it was common to both the Hydrins and Seapath).
