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

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.本数据集源自一项旨在重建更新世中期至晚期（约1500-125 ka）大西洋经向翻转环流（Atlantic Meridional Overturning Circulation, AMOC）的研究项目。本研究采用铁锰结壳有孔虫与鱼残骸的εNd值，沿大西洋西边界构建经向剖面，以追踪冰期与间冰期循环中大西洋经向翻转环流的强弱变化。研究结果证实，本数据集可如实反映不同时期的大西洋经向翻转环流，并为冰期-间冰期循环中该环流的强弱波动提供了实证支撑。
