Marine biogenic calcification Wikipedia

Marine biogenic calcification is the process by which marine organisms such as oysters and clams form calcium carbonate. Seawater is full of dissolved compounds, ions and nutrients that organisms can utilize for energy and, in the case of calcification, to build shells and outer structures. Calcifying organisms in the ocean include molluscs, foraminifera, coccolithophores, crustaceans ...

Nucleation of metastable aragonite CaCO3 in seawater

Mar 17, 2015· Oceanic calcium carbonate is the primary CO 2 sink in the global carbon cycle, but for a given p CO 2, aragonite will sequester less carbon than calcite. Furthermore, a substantial fraction of the shells of molluscs, pteropods, and corals are biomineralized aragonite, and its higher solubility renders marine life more vulnerable to increasing ...

Calcite Origin and occurrence | Britannica

Calcite Calcite Origin and occurrence: A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth’s calcite is of magmatic (, igneous) origin; it is the chief constituent of the rare rock called carbonatite.

Carbon capture and storage Wikipedia

Carbon capture and storage (CCS) (or carbon capture and sequestration or carbon control and sequestration) is the process of capturing waste carbon dioxide (CO 2) usually from large point sources, such as a cement factory or biomass power plant, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground geological formation.
