Nd isotope ratios from ODP Leg 154, Site 926 in the deep Equatorial Atlantic over the last 1.5 Myr

Abstract: This dataset was produced as a part of a project aiming to reconstruct the Atlantic Meridional Overturning Cirvulation (AMOC) throughout the middle to late Pleistocene (~1500-125 ka). We used εNd values of Fe-Mn encusted foraminifera and fish debris, to generate meridional profiles along the western boundary of the Atlantic Ocean and trace the weakening and strengthening of the AMOC over glacial and interglacial cycles. The results provide evidence that the data indeed reflects AMOC through time and provide evidence for the weakening and strengthening of the AMOC over glacial-interglacial cycles.摘要：本数据集为某研究项目的产出成果，该项目旨在重建中更新世至晚更新世（约1500~125 ka）期间的大西洋经向翻转环流（Atlantic Meridional Overturning Circulation, AMOC）。我们采用铁锰结壳有孔虫与鱼残骸的εNd值，沿大西洋西部边界构建经向剖面，以追踪冰期-间冰期旋回中AMOC的强弱变化。研究结果证实，本数据集确实能够反映随时间演化的AMOC状态，并为冰期-间冰期旋回中AMOC的强弱变迁提供了实证依据。
