Contrasting drivers and trends of ocean acidification in the subarctic Atlantic
Abstract The processes of warming, anthropogenic CO 2 (C anth ) accumulation, decreasing pH T (increasing [H + ] T concentration in total scale) and calcium carbonate saturation in the subarctic zone of the North Atlantic are unequivocal in the time-series measurements of the Iceland (IS-TS, 1985–20...
