Abstract:The southern Kattegat is characterized by a strong halocline at a water depth of 10–20 m. Samples were collected within and below the halocline at 12–58 m. A Q-mode factor analysis identified three major and three minor foraminiferal assemblages, each characterized by one diagnostic species. Linear regression analyses showed that the distribution of assemblages and their diagnostic species is associated with substrate and hydrography. The Bulimina marginata assemblage is connected with fine-grained, organic-rich sediments below the halocline. The Elphidium excavalum and the Eggerelloides scabrus assemblages show weak correlations with substrate and are presumably connected with the halocline. Minor assemblages of Cibicides lobatulus and Textularia bocki are associated with coarse-grained sediments. The Stainforthia fusiformis assemblage has only weak correlation with substrate and hydrography.
