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. WebCurrently, the average pH for the global ocean is about 8.1, meaning seawater is slightly basic. Because most of the inorganic carbon dissolved in the ocean exists in the form of bicarbonate, bicarbonate can respond to disturbances in pH by releasing or incorporating hydrogen ions into the various carbon compounds.
