An evaluation of benthic foraminiferal B/Ca and d11B for deep ocean carbonate ion and pH reconstructions

Yu, Jimin; Foster, Gavin; Elderfield, H; Broeker, Wally S.; Clark, Elizabeth

Description

Reliable reconstructions of deep ocean carbonate ion concentration, [CO32-], and pH are crucial to understand mechanisms responsible for the past atmospheric CO2 variations observed in ice cores. However, it is challenging to reconstruct past deep water [CO32-] and pH and literature results from different proxies conflict, warranting careful investigations on possible reasons for the existing inconsistencies. Here, we present the first down core B/Ca and -11B records measured in an epifaunal...[Show more]
