Did you know?
Web15 de mai. de 2015 · The oceans are naturally alkaline, usually with a pH of around 8.2. As the oceans absorb CO 2, carbonic acid (H 2 CO 3) is formed. This then releases hydrogen ions (H +) which make the oceans become more acidic. Web2 de mar. de 2024 · The uptake of anthropogenic CO 2 over the last 150 years has made the surface ocean more acidic with a decrease in global mean pH from ∼ 8.2 around 1850 to ∼ 8.1 today ( Feely et al. , 2009; Jiang et al. , 2024) . This decrease in pH equates to a ∼ 30 % increase in the concentration of H + ions.
