| Abstract | {The boron isotopic composition ($δ$11B) of coral skeleton is a proxy for seawater pH. However, $δ$11B-based pH estimates must account for the pH difference between seawater and the coral calcifying fluid, $Δ$pH. We report that skeletal $δ$11B and $Δ$pH are related to the skeletal carbon isotopic composition ($δ$13C) in four genera of deep-sea corals collected across a natural pH range of 7.89–8.09, with $Δ$pH related to $δ$13C by $Δ$pH = 0.029 × $δ$13C + 0.929 |
