Cruise summary report
|Ship name (ship code)||RRS James Clark Ross (74JC)|
|Cruise identifier||JR20030816 (JR99)|
|Cruise period||2003-08-16 — 2003-08-27|
|Port of departure||Cork, Ireland|
|Port of return||Immingham, United Kingdom|
|Objectives||JR99 was intended as a commissioning, calibration, trials and training cruise between the summer refit and the vessel sailing for the Antarctic. It was an opportunity for the new ITS, ETS and GSD staff to become familiar with the ship-fitted equipment; this necessarily involved carrying out a realistic survey in deep water. Specific objectives included the following:
1. Calibrate the EM120 multibeam echo sounder for pitch and roll.
2. Establish the operational limits of the EM120 and TOPAS sub-bottom profiler in rough water.
3. Check performance of the Simrad Synchronisation Unit (SSU).
4. Test towed magnetometer in stand-alone mode.
5. Review performance of on-board scientific systems and carry out general maintenance.
6. Install and test new version of Scientific Computer System (SCS) software.
