14C plateau tuning – A misleading approach or trendsetting tool for marine paleoclimate studies?

Michael Sarnthein and Pieter M. Grootes

Abstract. 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 and by coherent features in the 14C record of Hulu Cave back to 35 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.

Short summary
Changes in the geometry of ocean Meridional Overturning Circulation (MOC) are crucial in controlling past changes of climate and the carbon inventory of the atmosphere. However, the accurate timing and global correlation of short-term glacial-to-deglacial changes of MOC in various ocean basins still present a major challenge now met by the fine structure of jumps and plateaus in atmospheric and planktic radiocarbon (14C) concentration that reflect authentic changes in atmospheric 14C production.
