Dissolved inorganic carbon
= Dissolved inorganic carbon
{title2=$C$}
Dissolved inorganic carbon is the total dissolved carbon in inorganic species, principally aqueous <carbon dioxide>, bicarbonate and carbonate. A reservoir model may express its <concentration> in moles of carbon per kilogram of <water>. Air–sea exchange, river inputs, carbonate chemistry and burial affect its inventory; a single linear <concentration>-<pressure> relation is a model simplification.
