Summary: | At a fixed station in the southern Norwegian Sea in August 1969 plankton samples were taken over an eight days period every two hours with a DAVID-Neuston-Net and simultaneously with a modified Gulf-V-Sampler. The biomass of the invertebrates is given in total, subdivided into their most important groups, and correlated to hydrographical and meteorological conditions. The patterns of their vertical distribution in the 0-50 m layer are discussed. Five species of fish were found. Juvenile stages of Sebastes marinus and Scomber scombrus showed a preference for the surface layer during the night. Some aspects of the advantages of the surface layer for planktonic life are discussed. |
