World Ocean 14C plateau tuning

On the basis of minor time scale adjustments including the synchronization on IntCal20 the Suigetsu-based atmospheric 14C plateau structures are shown to be authentic. Their global significance is demonstrated by the coherence with the tree ring record 10 to 15 cal. ka. The suite of atmospheric structures can be recognized in high-resolution ocean sediment records independent of various processes leading to partial distortion of a sediment record. This provides a unique tool for global stratigraphic correlation and paleoceanographic studies as shown by supplementary figures and tables from 19 cores obtained from key locations in the world ocean.

基于包括IntCal20同步在内的微小时间尺度调整，研究表明基于诹访湖（Suigetsu）的大气14C平台结构是真实存在的。其全球意义通过与10至15校准千年（cal. ka）树木年轮记录的一致性得到证实。这套大气结构可在高分辨率海洋沉积物记录中被识别，且不受导致沉积物记录部分失真的各类过程影响。正如来自世界海洋关键区域的19个岩芯的补充图表所示，这为全球地层对比与古海洋学研究提供了一种独特工具。
