Dissolved inorganic carbon (DIC) refers to the sum of all inorganic carbon species present in water, primarily in the form of carbon dioxide (CO2), bicarbonate (HCO3-), and carbonate (CO32-). This term is crucial in understanding ocean carbon dynamics, as it plays a significant role in regulating the ocean's pH and its ability to absorb atmospheric CO2, which is fundamental to the process of ocean acidification.
