2016 Sally Ride System Review

Cruise ID: SR1601
Multibeam System: EM122/EM712
Dates: July 25-28, 2016

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.
