What is the principal mechanism by which the ocean acts as a carbon sink?

The principal mechanism by which the ocean acts as a carbon sink is the dissolution of atmospheric carbon dioxide (CO2) into seawater, followed by chemical reactions that convert the dissolved CO2 into other forms of carbon. A carbon sink is a natural or artificial reservoir that accumulates and stores carbon-containing chemical compounds for an indefinite period, thereby removing CO2 from the atmosphere. When atmospheric CO2 dissolves in seawater, it undergoes a series of chemical reactions. First, CO2 reacts with water....
