Excess carbon dioxide enters the ocean, reacts with water, decreases ocean pH and lowers carbonate ion concentrations, making waters more corrosive to marine species that need carbonate ions and dissolved calcium to build and maintain healthy shells and skeletons.
Operators could then remove water and sequester the excess carbon dioxide.
For example, in higher latitudes such as northern Canada and Greenland, coastal waters usually act as carbon sinks, absorbing excess carbon dioxide from the atmosphere.
Specimens of elkhorn coral living in water with excess carbon dioxide have been studied for fertilization rates, ability of larvae to settle on reef substrate (where they produce new corals), and subsequent growth and survival.3 Three levels of carbon dioxide were tested, corresponding to concentrations today, at mid-century, and at the end of the century on a high - emissions path.3, 5 At the mid-century concentration, the ability of fertilization to occur and for larvae to settle successfully on the reef was significantly reduced: around 52 percent, and the decline intensified to about 73 percent at the late - century concentration.3 The corals» ability to survive over the long run declined as well, by an average of 39 percent and 50 percent respectively.3, 4
These processes affect the transport of water, heat, salinity, nutrients and carbon in the ocean, impacting on the climate system by modifying it's ability to absorb human - emitted carbon dioxide and excess heat resulting from increased carbon dioxide concentrations.
Excess carbon dioxide in the atmosphere — in addition to contributing to climate change — is absorbed by the ocean, making sea water more acidic and leading to a suite of changes in ocean chemistry.
