Falkor 2013 Multibeam Echosounder System Review

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 not changed significantly since the 2012 trials in “Science” mode. Review of the noise results by Tim Gates indicates that there are some modules reporting higher noise levels compared to measurements taken by Gates in early 2012 and may warrant a closer investigation

Roger Revelle 2013 Quality Assurance Report

CruiseID: 
RR1301

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).

Falkor 2012 Multibeam Echosounder System Review

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 testing was conducted during a second set of trials while in transit from Newcastle-upon-Tyne, UK to Nuuk, Greenland in July 2012.
