Carbon dioxide exchange
Transcript
There is a constant vigorous exchange that is going two ways between the ocean and the atmosphere. So once the CO2 goes into the ocean then that CO2 forms carbonic acid, bicarbonate and carbonate ion, and it means that the ocean can take up more CO2, so at present, there is about 60 times as much carbon in the ocean as there is in the atmosphere.
