Abstract

Constraints on deep ocean carbonate chemistry are critical for understanding the processes responsible for glacial-interglacial changes in atmospheric pCO2 and the ocean feedbacks that amplify carbon cycle change. Here, we present the results of foraminifera density analyses (mass per feret diameter) as measured on the planktonic foraminifera G. ruber. These data are inconsistent with a co-registered B/Ca-based record of carbonate ion concentration (∆[CO32-]) suggesting a decoupling of bottom water and porewater carbonate chemistry.
