Selected records from core HH12-940PC. a Planktic δ18O measured in the foraminiferal species Neogloboquadrina pachyderma. b Corrected (see “Methods”) benthic δ18O measured on Cibicidoides wuellerstorfi (blue squares), Melonis barleeanus (red squares) and Cassidulina neoteretis (black squares). c Planktic δ13C measured in N. pachyderma. Vertical grey bar indicates typical range of glacial and interglacial values. d Benthic δ13C measured in C. wuellerstorfi (blue squares), M. barleeanus (red squares) and C. neoteretis (black squares). Vertical grey bar indicates typical range of glacial and interglacial values (see text for explanation). e Percentage distribution of polar planktic foraminiferal species N. pachyderma (note inverse scale) with position of calibrated AMS-14C dates indicated, asterisks mark outlier dates (see Table 1). f Percentage of epifaunal benthic species C. wuellerstorfi. g Percentage of shallow infaunal benthic species C. neoteretis. h Concentration of calcareous nodules > 0.5 mm from authigenic carbonate precipitation (see text for explanation) in number per gram dry weight sediment (black curve) and concentration of pyrite particles > 0.5 mm in number per gram dry weight sediment (red curve). Corelog shown to the right of (h). YD ,Younger Dryas; LGM, Last Glacial Maximum; H , Heinrich stadial; MIS, Marine Isotope Stage. Blue bars mark Heinrich stadials, horizontal black lines isotope stage boundaries.
