Vessel: USCGC Healy
Multibeam System: EM122
Dates: August 13-24, 2014
Gates Acoustic Services was tasked by SCRIPPS Institute of Oceanography to investigate and quantify acoustic issues associated with operation of the USCGC HEALY (WAGBG20). An at-sea investigation was accomplished during ship operations in deep water out of Nome, Alaska on August 13-24, 2014.
During the at sea test on HEALY, the primary goal was to determine ship acoustic and bubble sweepdown characteristics and to assess their potential impacts to sonar performance. The Kongsberg EM 122 sonar was the primary focus of this testing. Additional goals of this test were to determine propeller cavitation characteristics and to obtain a preliminary snapshot of acoustic noise generated while operating in various ice conditions.
