2014 Falkor Spring Quality Assessment Report
Vessel: R/V Falkor Multibeam System: EM302/EM710 Dates: February 4-7, 2014 The transducer impedances are similar to baseline measurements in 2012 and with those taken in 2013. Transducer conditions, based on these tests, are acceptable and there is no sign of degradation of the transducer arrays. Noise levels for the EM710 remain unchanged and very low.…

2014 Falkor Fall Quality Assessment Report
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…

2013 Falkor Multibeam Echosounder System Review
Vessel: R/V Falkor Multibeam System: EM710/EM302 Dates: April 2, 2012 The transducer impedances are similar to baseline measurements with exception of the EM710 transducer impedances. This latter potential issue is being examined with the manufacturer but we do not feel, after consultation with the manufacturer, that there is any cause for concern. Noise levels have…

2012 Falkor Multibeam Echosounder System Review
Vessel: R/V Falkor Multibeam System: EM302/EM710 Dates: May 2012 RV Falkor is equipped with Kongsberg Maritime (KM) EM302 and EM710 multibeam echosounders (MBES). Both systems underwent Sea Acceptance Trials (SATs) in May 2012 in Sognefjord, Norway. The bathymetric and topographic constraints imposed by the fjord limited the ability to fully test the EM302. Additional system…
