Abstract

A number of bottom-sediment samples from the Skagerrak have been studied. The surface-sediment samples reflect the presence of three main sediment types, with a fourth which occurs more scattered. A selection of 50 samples was used for the study of the foraminifers of the >125- μm fraction. Benthic foraminifers dominate the assemblages. Using factor analysis and the computer program CABFAC, the benthic foraminiferal data were reduced to five factors. Eight species have proven to be significant. The factors (benthic foraminiferal assemblages) are dominated by Bolivina, cf. B. robusta, Elphidium excavatum, Cassidulina laevigata, Bulimina marginata, Melanis barleeanum, Globobulimina turgida and Hyalines balthica, respectively. The first factors are clearly related to known hydrographic and bottom conditions.
