Surface ocean pH variations since 1689 CE and recent ocean acidification in the tropical South Pacific

Increasing atmospheric CO2 from man-made climate change is reducing surface ocean pH.
Due to limited instrumental measurements and historical pH records in the world's oceans,
seawater pH variability at the decadal and centennial scale remains largely unknown and
requires documentation. Here we present evidence of striking secular trends of decreasing
pH since the late nineteenth century with pronounced interannual to decadal–interdecadal
pH variability in the South Pacific Ocean from 1689 to 2011 CE. High-amplitude oceanic pH …
