Variability in storm season intensity modulates ocean acidification conditions in the northern Strait of Georgia.

ABSTRACT: Large changes in marine CO₂ chemistry manifest in areas with weakly-buffered seawater where ocean acidification (OA) acts in concert with natural CO₂ additions. These settings can exhibit periods of extreme OA in the form of multiple co-occurring stressors, including calcite undersaturation and low pH. Such conditions were observed in the northern Strait of Georgia, on the northeast Pacific coast, where extreme OA spanned a 3-year period. Here, we utilized an 8-year, highly-resolved record of seawater CO₂ partial pressure and total dissolved inorganic carbon to decompose the drivers of this extreme OA. We find that variability in storm season intensity shaped the extent of conservative mixing and biogeochemical drivers such that manifests of extreme OA aris
