|Cruise period||1994-08-04 — 1994-08-22|
|Port of departure||Lowestoft, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
|Objectives||1. To measure the distribution and abundance of commercial flatfish species by means of a beam trawl survey, as part of an ICES coordinated programme in the North Sea and parts of area VII.
2. To collect additional biological data on sole and plaice, and commercially important non-quota species, especially dab, turbot, brill and crab.
3. To describe the seabed sediments and epibenthos using both photographic and trawl by catch data, and also the ROXANN acoustic and seabed discrimination system.
