Vessel: R/V Sikuliaq
Multibeam System: EM302/EM710
Dates: September 12-18, 2014
Gates Acoustic Services was tasked by University of Alaska, Fairbanks, to investigate and quantify acoustic issues associated with operation of the R/V SIKULIAQ. An at-sea investigation was accomplished during ship operations in deep water out of San Juan, Puerto Rico on September 12-18, 2014.
During the at sea test on SIKULIAQ, the primary goal was to determine ship acoustic and bubble sweepdown characteristics and to assess their potential impacts to sonar performance. The Kongsberg EM 302 sonar was the primary focus of this testing with the Kongsberg EM 710 as a secondary priority. Additional goals of this test were to determine propeller cavitation characteristics and to obtain a preliminary snapshot of the expected acoustic background of the sonar region in open water conditions.
