Purpose | Trials |
Objectives | Cruise JR50 comprised trials of new scientific equipment installed on RRS James Clark Ross
during the summer refit. These trials mainly consisted of Sea Acceptance Tests of the new multibeam echo sounder and sub-bottom profiler, the purchase and installation of which was funded by an award from the Joint Infrastructure Fund. The cruise also provided an opportunity to test pre-existing echo sounding systems following refitting of transducers, and to prove the newly-installed NOAA Scientific Computing System. The Sea Acceptance Tests were successful and demonstrated that the new EM120 multibeam echo sounder can provide higher resolution sea-floor imagery than any other multibeam system presently in operation on a civilian vessel. Following the cruise there were some minor issues to resolve before the new sonar systems could be accepted, but these were second order problems which mainly related to some of the ancillary equipment. |
