Reconstructing ocean pH with boron isotopes in foraminifera
In order to better understand the effect of CO2 on the Earth system in the future geologists may look to CO2-induced environmental change in Earth’s past. Here we describe how CO2 can be reconstructed using the boron isotope composition (δ11B) of marine calcium carbonate. We review the chemical prin...
