Cruise ID: NA126
Multibeam System: EM302
Dates: July 3-10, 2021
The 2021 EM302 Quality Assessment Tests (QATs) were conducted primarily during NA126, the engineering shakedown cruise, with some additional ship self-noise data collected during NA127. This years QAT was very important as in 2020 during NA118/NA119 it was discovered that there was a significant increase in the self-noise of the Nautilus introduced during the installation of a new propulsion system, which was not identified during over the course of the 2020 season. This issue, coupled with the relocation of the two Seapath antennas, as well as a lengthening of the aft portion of the ship meant that there was a high level of interest in assessing the multibeam system performance prior to the start of the 2021 season.
