Quantitative studies of foraminiferal faunas and isotope ratios have been done in two gravity cores from the Vøring Plateau. Core 23199 from about 2000 m water depth included sediments younger than oxygen Stage 7. Core 23205 from about 1400 m ended in sediments from Stage 5. According to the transfer temperatures, the onset of abundances of Cibicidoides wuellerstorfi and the δ 13 C values of Neogloboquadrinapachyderma , the Vøring Plateau was covered by pack‐ice during Stages 6,4,2 and, to some extent, also during Stage 3. Ice‐free sea‐surface conditions prevailed from late Substage 5e throughout Stage 5 and during stage 1. The transition from Stage 6 to Stage 5 (Termination II) took place in two steps: Ila is defined by the δ 18 O signal of N. pachyderma (reduced global ice volume) and lib by the increased occurrence of C. wuellerstorfi (melting of local pack‐ice). A contemporaneous development of an interglacial deep‐water circulation system is indicated.
