Reconstructing Ocean pH with Boron Isotopes in Foraminifera
In order to better understand the effect of CO 2 on the Earth system in the future, geologists may look to CO 2 -induced environmental change in Earth's past. Here we describe how CO 2 can be reconstructed using the boron isotopic composition (δ 11 B) of marine calcium carbonate. We review the...

can be reconstructed using the boron isotopic composition (δ

B in a variety of marine carbonates shows a coherent relationship with seawater pH, in broad agreement with simple models for this proxy. Offsets between measured and predicted δ

B may in part be explained by physiological influences, though the exact mechanisms of boron incorporation into carbonate remain unknown. Despite these uncertainties, we demonstrate that δ
11
B may provide crucial constraints on past ocean acidification and atmospheric CO
