DESCRIPTION: The project funded detailed B proxy records for a number of locations across the Pacific and Atlantic to establish regional anomalies in surface ocean carbonate chemistry relative to longer-term trends.
OUTCOMES: The boron isotope data from surface dwelling foraminifera from different ocean settings consistently suggest surface ocean acidification of approximately -0.3 pH units. Extension of the Pacific record into the Paleocene and Eocene corroborates a long-term decrease in surface ocean pH consistent with the long-term warming and d13C trends.
