The R/V Sally Ride is equipped with a Kongsberg Maritime EM122 (12 kHz) and EM712 (40-100 kHz) multibeam echosounders both utilizing a Seapath 330+ (primary) and iXBlue HYDRINS (secondary) positioning and attitude reference system. This report describes the procedures and results from a review of system geometry, geometric calibrations (‘patch tests’), and assessments of swath accuracy and swath coverage conducted during cruise SR1601 (July 25-28, 2016) off the coast of Washington. These tests were conducted to verify functionality and data quality at the beginning of each multibeam system’s service life, setting a baseline for future evaluations.
