The Denmark Strait is a key area for the exchange of water masses and functions as a deep-water gateway between the Nordic Seas and the North Atlantic. Thus it constitutes an important part of the global thermohaline circulation (THC). The gateway aperture is influenced by eustatically and isostatically controlled changes of the Denmark Strait sill and by alteration in density contrasts between the water masses in North and South. In order to determine the faunal exchange through the changing aperture, benthic foraminiferal assemblages were analysed. Eight surface sediment samples were taken along the East Greenland continental margin during the RV Polarstern cruise ARK-XVIII/1 in July 2002 by means of a multicorer and a box corer respectively. Faunal assemblages of living (stained) and dead benthic foraminifera north and south of the Denmark Strait (980-2564 m water depth) were compared with each other. Northern and southern stations exhibit clear differences in abundances, diversities, number of species, ... : Supplement to: Lorenz, Andrea (2005): Variability of benthic foraminifera north and south of the Denmark Strait.
