|Cruise period||2003-05-08 — 2003-05-27|
|Port of departure||Aberdeen, United Kingdom|
|Port of return||Aberdeen, United Kingdom|
|Objectives||1. To develop and refine the twin trawling technique and collect data on the effects of groundgear choice on the selectivity of the GOV trawl.
2. To test rigging and set up changes on the performance of the single GOV.
3. To obtain quantitative information on fish populations in the mouth of the trawl, between the wings and as close to the doors as possible. The upgraded SM2000 sonar mounted on the RCTV and new fibre-optic cable will be used.
4. Simultaneous video footage, using the self-recording ccd cameras, will be collected to give information on species identification. A stereo-pair configuration will be tested.
