Ziel der Reise / Objectives of Cruise:
The purpose of this cruise was to outline the nursery areas of common gadoids in the northern North Sea. Distribution patterns have been described during the 70 and 80 ties, but little information is available from the present period where relative abundances of gadoids have changed markedly. Especially the Atlantic cod population has declined in size, and the cruise focus on distribution and ecology of the young stages of this species. The juveniles were caught by a small meshed trawl in a range of stages, the smallest were still in the pelagic stages when the larger were in the transitionary stage to a demersal habitat. Special focus was put on physical/biological linkages, and sampling was transect-wise, across frontal areas. Findings were related to hydrography, and frontal hydrography was described off the Banks and the Shelf Slope. "Helge Paulsen as additional PI"
