项目摘要
The proposed research would produce a thorough quantitative foraminiferal study of 500 deep-sea sediments samples and aims to reconstruct the paleoceanographic changes in the West Pacific Ocean in the vicinity of the Kuroshio Current. The study is based primarily on coarse fraction (>150 micron) microscopic examinations. However, the micropaleontological work on planktonic and benthic foraminifera assemblages will be complemented by the analysis of stable isotopes (O18 & C13 ratios) measured on foraminifera extracted from selected samples. These analyses should confirm the stratigraphy of Site IBM-3C as well as inform the paleoceanographic and paleoclimatic interpretations obtained for the samples.At such a subtropical location (30deg N), the study of the planktonic assemblages is a very useful contribution for reconstructing changing surface conditions because glacial and interglacial faunal assemblages are very contrasted. In particular, the study will provide needed data about changes in the Kuroshio Current path, which are potentially linked to changing ENSO intensity in the Pacific Ocean. The study focuses on the last 6 Ma.In the area of the IBM and at 2114 water depth, the low resolution study of the benthic foraminifera assemblages extracted from 50 coarse fraction samples will provide some estimates of paleo-depth and deep-water environmental changes at a time resolution better than 1 Ma throughout the Neogene. All analyses will be performed in the Godwin Laboratory for Paleoclimate Research (Earth Sciences Department, Cambridge University) from carefully selected Neogene sediments taken on board JOIDES Resolution during Leg 350 by Dr. Vautravers sailing as a foraminifera expert.
这项拟议的研究将对500个深海沉积物样本进行全面的有孔虫定量研究,旨在重建黑潮附近西太平洋的古海洋变化。这项研究主要基于粗颗粒(>;150微米)显微镜检查。然而,浮游和底栖有孔虫组合的微体古生物学工作将得到从选定样品中提取的有孔虫的稳定同位素(O18和C13比值)分析的补充。这些分析应该证实IBM-3C站点的地层学,并为样品获得古海洋学和古气候解释。在这样一个亚热带位置(30°N),浮游生物组合的研究对于重建不断变化的地表条件是非常有用的,因为冰川和间冰期动物组合的差异非常大。特别是,这项研究将提供有关黑潮洋流路径变化的必要数据,这可能与太平洋ENSO强度的变化有关。这项研究的重点是最近6 Ma。在IBM地区,在2114水深,从50个粗组分样品中提取的海底有孔虫组合的低分辨率研究将提供一些估计古深度和深水环境变化的时间分辨率在整个新近纪好于1 Ma。所有分析都将在戈德温古气候研究实验室(剑桥大学地球科学系)进行,这些沉积物是由Vautraver博士作为有孔虫专家在350航次期间从JOIDES分辨率号上精心挑选的新近纪沉积物中采集的。
