Geochemical records preserved in the long-lived carbonate skeleton of corals provide one
of the few means to reconstruct changes in seawater pH since the commencement of the
industrial era. This information is important in not only determining the response of the
surface oceans to ocean acidification from enhanced uptake of CO2, but also to better
understand the effects of ocean acidification on carbonate secreting organisms such as
corals, whose ability to calcify is highly pH dependent. Here we report an∼ 200year δ11B …
