Vessel: R/V Falkor
Multibeam System: EM710/EM302
Dates: September 22-24, 2014
The R/V Atlantis replaced its EM122 multibeam echosounder with an EM124 upgrade during the 2020-21 mThe EM302 and EM710 multibeams were successfully calibrated and verified for use with both the loaner Seapath MRU and the new POS MV. Angular offsets were small except for the roll bias for both the EM710 and EM302. As both multibeam systems have the same large roll bias, it is likely the result of a shift in the mounting angle of the MRU. Both SIS acquisition systems have been updated with the new calibration results.
