Description:

The spatiotemporal variabilities and drivers of ocean acidification (OA) metrics, [H+], pH, and aragonite saturation state (Ωarag) across environmental gradients remain poorly constrained. We use a novel high-precision measurement of underway pH to investigate the hemispheric-scale distributions of OA metrics from East Asia to the Arctic Ocean. While temperature and its induced air-sea gas exchange fundamentally control the OA metrics distributions, we show that biological activity exerts the most prominent but different modifications on pH and Ωarag patterns. Strong photosynthesis counteracts the temperature-driven pH pattern but reinforces that of Ωarag. Ice melt-induced dilution in the Arctic Ocean
