WebbOcean Acidification. As human-induced emissions of carbon dioxide (CO 2) build up in the atmosphere, excess CO 2 is dissolving into the oceans where it reacts with seawater to form carbonic acid, lowering ocean pH levels (“acidification”) and threatening a number of marine ecosystems. Currently, the oceans absorbs about a quarter of the CO ... Webb6 mars 2024 · A pH of 7.0 is a completely neutral water (neither acidic nor basic); a pH below 7.0 is acidic. Around 150 years ago, the average ocean pH was 8.3, so the oceans are moving toward being more acidic. We call this an acidification process because the trend of ocean pH change is moving toward lower pH values.
