Paleointensity versus age of all the sedimentary sequences of the present study

Paleointensity versus age of all the sedimentary sequences of the present study, of the synthetic curve resulting from its compilation from other curves, and of the reference curve from ODP Site 984 (Channell, 1999). For the compilation, data have been averaged using a sliding window of 2 ka (the variance is marked by the grey shadow). Dashed lines show some of the correlations. The grey lines show the location of the low paleointensities related to geomagnetic excursions. Note that the lowest paleointensities in the time span of Blake are at c. 129 ka. (see Fig.11)

本研究所有沉积序列的古强度（paleointensity）随年龄的变化关系、由其他曲线汇编得到的合成曲线，以及来自大洋钻探计划（Ocean Drilling Program, ODP）984站位的参考曲线（Channell, 1999）。在数据汇编过程中，采用2千年（ka）的滑动窗口对数据进行平均，方差以灰色阴影标记。虚线展示了部分相关关系；灰色线条标注了与地磁漂移（geomagnetic excursion）相关的低古强度区域位置。需注意，布莱克漂移（Blake excursion）时段内的最低古强度值出现在约129千年处（详见图11）。
