Surface ocean pH and buffer capacity: past, present and future.

ABSTRACT: The ocean's chemistry is changing due to the uptake of anthropogenic carbon dioxide (CO₂). This phenomenon, commonly referred to as "Ocean Acidification", is endangering coral reefs and the broader marine ecosystems. In this study, we combine a recent observational seawater CO₂ data product, i.e., the 6^th version of the Surface Ocean CO₂ Atlas (1991-2018, ~23 million observations), with temporal trends at individual locations of the global ocean from a robust Earth System Model to provide a high-resolution regionally varying view of global surface ocean pH and the Revelle Factor. The climatology extends from the pre-Industrial era (1750 C.E.) to the end of this century under historical atmospheric CO₂ concentrations (pre-2005) and the
