Abstract

These data include solid phase measurements on 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, Liaison autosampler coupled to a Picarro cavity ring-down spectrometer, and Element Analyzer coupled to a Picarro cavity ring-down spectrometer. These data contributed to our understanding of the carbonate chemistry system in this region, particularly regarding carbona...
