Abstract—Marine isotope stage (MIS) 9 is one of the least investigated Pleistocene interglaciations. The
present study describes reconstructions of deep-water conditions during this time interval based on benthic for-
aminiferal assemblages from sediment core M23414 (Rockall Plateau, North Atlantic). The results of faunal
analysis were supported by planktic ¹⁸O, sea surface temperature reconstructions based on planktic foramin-
iferal assemblages and content of ice rafted debris. Statistical data processing using principal component anal-
ysis revealed five climate-related benthic foraminiferal associations that changed in response to alterations of
deep-water circulation.
