Abstract
On the Kolbeinsey Ridge, north of Iceland, 92 species of peracarid crustaceans were sampled using the epibenthic sledge. For an analysis of the multispecies distribution pattern across the ridge, a total of 46 species have been considered, which occurred at least at two stations and with at least 5% relative abundance at any one station. The analysis revealed four assemblages: a deep species assemblage, an eastern slope assemblage, an ubiquitous species assemblage and a western slope assemblage. The western slope assemblage consists mainly of Amphipoda, which were most abundant and diverse on the western slope. The ubiquitous and eastern slope assemblages, however, are dominated by Isopoda, which also comprised most species and individuals on the eastern slope. Cumaceans were the most representative species of the deep species assemblage. These differences in species composition and abundance can probably be attributed to food supply and sediment composition, rather than to salinity or bottom water temperature.
