  • Integrated Neogene biochemostratigraphy at DSDP Site 296 on the Kyushu–Palau Ridge in the western North Pacific Reviewed International journal

    2019.9

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    We revisited the stratigraphy at Deep Sea Drilling Project (DSDP) Site 296, which has promise as a reference sequence for the mid-latitude northwestern Pacific. We constructed the biostratigraphy (calcareous nannofossils, planktic foraminifera, and radiolaria) and chemostratigraphy (strontium isotope ratios, and stable carbon and oxygen isotope ratios) to reveal continuous sedimentation at Site 296 through the past 20 million years (Myr). The biostratigraphy of calcareous nannofossils comprised 27 biohorizons from biozones NN2 to NN21 (early Miocene to Pleistocene), which are consistent with the biohorizons of planktic foraminifera and radiolaria. The uninterrupted sedimentation throughout the past 20 Myr was further supported by strontium isotope stratigraphy aligned tuned to nannofossil datums and by correlation of stable isotope data from benthic foraminifera with an isotopic compilation from the Pacific Ocean. The refined age–depth model showed low sedimentation rates (<2 cm/kyr) through most of the Miocene and higher sedimentation rates (2–4 cm/kyr) during the Plio–Pleistocene, and potentially identified the “biogenic bloom” event from the late Miocene to early Pliocene. The continuity of sedimentation through the middle Miocene contrasts with the shipboard biostratigraphy, which inferred a hiatus (erosion or non-deposition) during the middle Miocene. Thus, the revised stratigraphy at Site 296 provides a key to correlation with other deep-sea sites in the North Pacific. Our revised age–depth model provides a framework for future studies of important climatic events during the Miocene, including the Miocene Climatic Optimum, the middle Miocene Climatic Transition, and the late Miocene global cooling under the influence of the past Kuroshio Current.

  • Seasonal variability of δ18O and δ13C of planktic foraminifera in the Bering Sea and central subarctic Pacific during 1990-2000 Reviewed

    30 ( 10 )   1328 - 1346   2015.10

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    We evaluated a 10 year time series of δ18O and δ13C records from three planktic foraminifers (Neogloboquadrina pachyderma, Globigerina umbilicata, and Globigerinita glutinata) in the Bering Sea and central subarctic Pacific with a focus on their responses to environmental changes. Foraminiferal δ18O followed the equilibrium equation for inorganic calcite, with species-specific equilibrium offsets ranging from nearly zero (-0.02‰ for N. pachyderma and -0.01‰ for G. umbilicata) to -0.16‰ (G. glutinata). Equilibrium offsets in our sediment trap samples were smaller than those from plankton tow studies, implying that foraminiferal δ18O was modified by encrustation during settling. Habitat/calcification depths varied from 35-55 m (N. pachyderma and G. umbilicata) or 25-45 m (G. glutinata) during warm, stratified seasons to around 100 m during winter, when the mixed layer depth increases. Unlike δ18O, foraminiferal δ13C showed species-specific responses to environmental changes. We found a dependency of δ13C in G. umbilicata on CO32- concentrations in ambient seawater that agreed reasonably well with published laboratory results, suggesting that δ13C of G. umbilicata is subject to vital effects. In contrast, δ13C of N. pachyderma and G. glutinata are likely affected by other species-specific biological activities. Seasonal flux patterns reveal that fossil records of N. pachyderma and G. glutinata represent annual mean conditions, whereas that of G. umbilicata most likely indicates those of a specific season. Because none of these three taxa was abundant from December to February, their fossil records likely do not reflect isotope signals from cold seasons.
