What is Oolitic Aragonite? — Calcean Minerals & Materials LLC

Oolitic aragonite naturally pulls carbon dioxide from the atmosphere during its formation and is a renewable resource. Oolitic aragonite is biogenic meaning that it is produced by living organisms. It naturally forms during events called 'whitings.' Whitings can be seen in satellite imagery as wispy white clouds in the water.

When we increase the CO2 in the atmosphere, then the dissolution of this polluting gas in the water is increased and this leads to the presence of hydrogen ions (H+). This process is called sea acidification. In this more acidic water, hydrogen ions do affect the skeletons and shells of of marine species, being made out of aragonite.
