Narrative

The vessel sailed at 21:00 on 9 June 2002 Belfast and proceeded to the first station off county Down (Figure 1b). Sampling started at 01:30 on 10 June. The survey was completed at 05:00 on 12 June.

Plankton and fish larvae were sampled with the Gulf VII high speed plankton sampler and young pelagic juvenile cod, haddock and whiting, with the 5m² MIK net. Both gears were deployed to within 3m of the seabed in a double oblique manner. MIK nets were deployed at night, whilst the majority of gulf deployments took place during the day.

Samples were sorted, identified, enumerated and weighed onboard within 20 minutes of capture. Gadoids were fixed in 99% ethanol.
