Stable isotope ratios of benthic foraminifera in mid-Pleitsocene sediments of ODP Site 108-664 in the equatorial Atlantic

Five delta13C records from the deep ocean, extending back to 1.3 Ma, were examined in order to constrain changes in mean ocean carbon isotope composition and thermohaline circulation over the 41- to 100-ka climate transition. These data show that significant perturbations in mean ocean carbon chemistry were associated with the mid-Pleistocene climate transition. […]

五组源自深海、追溯至130万年前的大洋δ13C记录被加以研究，旨在约束41至10万年气候过渡期间平均海洋碳同位素组成以及热盐环流的变化。这些数据显示，平均海洋碳化学组成在新生代中期气候过渡期间发生了显著的扰动。
