ABSTRACT
The major portion of carbon in the oceans occurs as part of the carbonate system. This system involves the following equilibria: https://www.w3.org/1998/Math/MathML"> CO 2 ( g ) = CO 2 ( aq ) https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429096631/3832ab00-3454-4bf6-af5b-7cfe32e103df/content/equ7_1.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> https://www.w3.org/1998/Math/MathML"> CO 2 ( aq ) + H 2 O = H + + HCO 3 − https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429096631/3832ab00-3454-4bf6-af5b-7cfe32e103df/content/equ7_2.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> https://www.w3.org/1998/Math/MathML"> HCO 3 − = H+ + CO 3 2 − https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429096631/3832ab00-3454-4bf6-af5b-7cfe32e103df/content/equ7_3.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> https://www.w3.org/1998/Math/MathML"> Ca 2 + + CO 3 2 − = CaCO 3 ( S ) https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429096631/3832ab00-3454-4bf6-af5b-7cfe32e103df/content/equ7_4.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
