Mitigating the atmospheric CO2 increase and ocean ...

2008-4-23 · [2] The emission of CO 2 into the atmosphere from human activities leads to an increase in the partial pressure of atmospheric CO 2, and in response to this, there is a net flow of gaseous CO 2 into the surface layer of the ocean. Once dissolved in surface water, CO 2 combines with water to form a weak acid (carbonic acid, H 2 CO 3), which then dissociates to …
