Ziel der Reise / Objectives of Cruise:
Demersal trawling survey to assess pre-recruit year class strenghts of cod, haddock, whiting, saithe, Norwey pout, herring, mackerel and sprat. 1. To undertake a demersal trawling survey of the North Sea. 2. To obtain temperature and salinity data from surface and sea bed at each trawling location. 3. To carry out benthic sampling along the track of as many trawl stations as time permits.
