E.: A benthic δ13C-based proxy for atmospheric pCO2 over the last 1.5
[1] A high‐resolution marine proxy for atmospheric pCO2 is needed to clarify the phase lag between pCO2 and marine climate proxies and to provide a record of orbital‐scale pCO2 variations before the oldest ice core measurement at 800 ka. Benthic d13C data should record deep ocean carbon storage and,...

Summary: | [1] A high‐resolution marine proxy for atmospheric pCO2 is needed to clarify the phase lag between pCO2 and marine climate proxies and to provide a record of orbital‐scale pCO2 variations before the oldest ice core measurement at 800 ka. Benthic d13C data should record deep ocean carbon storage and, thus, atmospheric pCO2. This study finds that a modified d13C gradient between the deep Pacific and intermediate North Atlantic (Dd13CP−NA |
