The elements of the biogeochemical cycles are considered essential ocean variables (EOV) as defined by the Global Ocean Observing System. In order to study biogeochemical cycles, we need to measure [...] alkalinity, which provides information about the buffer capacity of seawater, relevant to study ocean acidification.

In laboratory experiments, they observed that diatoms under [...] deep ocean. Thus, the CO 2 is removed from the global carbon cycle for a couple of thousand years.
