WebDissolved inorganic carbon (DIC), also known as ΣCO 2, is composed of three dominant species in seawater: dissolved carbon dioxide (CO 2 (aq)), bicarbonate (HCO 3 −), and carbonate (CO 3 2 −), having relative concentrations on the order of 1%, 90%, and 10%, … WebJun 9, 2024 · However, seawater is more sensitive to CBA than to DIC changes below the pK 1 of the carbonic acid system (pH ≈ 5.9). Conversely, the sensitivity toward DIC changes is larger than that due to CBA changes at pH > 7.5. This can be attributed to the number of protons released (Egleston et al., 2010).
