these patterns further, our research also involved interpretations of the observations by models, measurements
of inorganic carbon in sea water, and of CO2 in air near growing land plants.
Both processes involve the transport and the
use of inorganic carbon (Ci) coming from seawater for photosynthesis, and from animal metabolism for calcification.
In order to address the challenges of future ocean acidification at a regional scale, it is necessary to increase the resolution of spatial and temporal
monitoring of the inorganic carbon system beyond what is currently available.
And because oceans contain the greatest
concentration of inorganic carbon by far, the question remains has anthropogenic CO2 significantly exacerbated the corrosiveness of natural upwelling?
When CO2 first invades sunlit surface waters, it indeed dissolves into 3
forms of inorganic carbon (DIC) and lowers pH (DIC is discussed in How Gaia and Coral Reefs Regulate Ocean pH).
However, current understanding suggests that, unless substantial ocean circulation changes occur, plankton growth remains roughly unchanged because it is limited mostly by environmental factors, such as nutrients and light, and not by the
availability of inorganic carbon it does not contribute significantly to the ocean uptake of anthropogenic CO2.
That outlines the chemistry that links most of the
storage of inorganic carbon in the ocean to the amount of base cations (Ca, Mg,) in ocean water.
