In one example, formation of dissolved carbon dioxide (e.g., HCO3 −) in an aqueous growth medium including carbonate ions can occur via the reaction of carbonate ions with water to yield bicarbonate and the reaction of carbon dioxide with hydroxide to yield bicarbonate, as shown below:

Increasing the concentration of dissolved carbon dioxide in the bulk of growth medium in algaculture facility 104 by the addition of enriched growth medium 112 to the bulk of growth medium in the algaculture facility increases the availability of dissolved carbon dioxide for algae in the algaculture facility, thereby enhancing growth of the algae.

(e.g., user interface, valves, pumps, test equipment to assess dissolved carbon dioxide concentration, etc.).

The concentration of dissolved carbon dioxide in enriched growth medium 112 exceeds the concentration of dissolved carbon dioxide in growth medium 106.

Because of these restraints the oceans locally can release only a small part of the total dissolved carbon dioxide and, more importantly, when averaged over a year the amount released equals the amount dissolved, i.e. there is not net addition of carbon dioxide to the atmosphere from the oceans so long as the temperature averaged over a year remains constant from year to year.

1: Thermodynamics and charge balance place serious restraints on the ability of dissolved carbon dioxide to pass into the gas phase as a result of local temperature changes.

Considering this human production leads to the conclusion that there is necessarily a net increase in dissolved carbon dioxide (see Henry's Law above) and the calculations yield in this case a decreasing average pH in the oceans.

The audience for whom this piece is intended consists of people who know some chemistry and are uncertain about how to consider the often made claim by deniers that the oceans contain so much dissolved carbon that human production is inconsequential.
