The MAC was requested to review the modified system configuration and perform geometric calibrations (‘patch tests’) of the multibeam systems during a coring shakedown cruise northwest of San Diego. This report describes the procedures and results of the calibrations conducted during cruise SKQ201602S (March 9-12, 2016) in order to verify functionality following the antenna relocation. In addition to geometric calibrations, transmitter element impedance measurements were collected for both systems to identify early warning signs for any possible transducer degradation. Swath coverage versus depth was examined for both echosounders using data collected throughout transits and surveys of opportunity for other activities during SKQ201602S in depths of 10-2,000 m.
