ObjectivesThis cruise is in 2 parts.
1. To trial scientific equipment that will be used during the first research cruises on board CEFAS Endeavour. The trials are to:
a) ensure that deployed equipment can be safely deployed and recovered;
b) once deployed, that the equipment functions correctly;
c) non-deployed equipment (echo sounders, IT systems, data logging etc.) is functioning correctly and to familiarise staff with its use;
d) to familiarise officers, crew and scientists with the vessel, her equipment and cabilities;
e) to provide training opportunities for personnel involved in the use of new equipment and capabilities.
2. Undertake a multi-beam acoustic survey of wreck site in Dunwich area.
3. Undertake a multi-beam acoustic survey of relinquished gravel extraction site 222.
4. Evaluate Scanmar trawl monitoring system.
5. Test ITI trawl monitoring system (success of this item is essential for cruise 6/03).
6. Test and accept TV/Satellite system.
7. Continue with design EDC carriers for wet-lab.
8. Design balance head fittings for wet-lab.
9. Monitor CT room temperature controls.
10. Verify reeving on gear for below-deck winches.
11. If practical, to collect biological samples for species where market-based sampling is likely to be deficient in 2003 for EU data regulation requirements:
a) cod, length and otolith samples;
b) skates and rays, morphometric, maturity and length weight;
c) turbot and brill length and otolith samples.
12. If practical, recover and redeploy gabbard buoy.
13. If time and weather conditions allow, complete configuration of workboat davits.
