| Summary: | this volume). Here, stable isotopic data are reported on Neoglobo-quadrina pachyderma (sinistrally coiling [s.]) from the same sam-ples. Stable isotopic stratigraphy, integrated with calcareous nanno-fossil biostratigraphy, magnetostratigraphy, and strontium isotopic stratigraphy, provides a temporal framework for lithologic and faunal studies on this sequence. Significantly, the data trace the history of surface water environments in the Irminger Sea during the mid- to late Quaternary. Also, oxygen isotopic stratigraphy is intercalibrated with calcareous nannofossil and diatom zonations, including calibra-tion for the first time of two diatom biostratigraphic events in the late Quaternary of the North Atlantic (Koç and Flower, this volume). These data also improve the geographic coverage of Quaternary δ18O and δ13C records from the Nordic Seas. Site 919 in the southern Greenland Sea complements existing records from the Iceland Sea (Site 907; Fronval and Jansen, 1996; McManus et al., 1996), the Nor- |
