Abstract

These data include radiocarbon (C14) calendar ages measured on pelagic foraminifera species collected from sediment cores from the Cocos Ridge in the Eastern Equatorial Pacific. This cruise was aboard the R/V Sally Ride between 2021-11-20 and 2021-12-20. Instruments used were a multicorer and accelerator mass spectrometry . These data contributed to our understanding of the carbonate chemistry system in this region, particularly regarding carbonate dissolution in deep-sea sediments. Patrick Raft...
