From: New constraints on the postglacial shallow-water carbonate accumulation in the Great Barrier Reef
Summary of CaCO3 volumetrics by formation, and comparison between global and GBR regional deposits. The postglacial reefs and Halimeda deposits participate in the global carbon cycle by changing the alkalinity of the shallow ocean, affecting CO2 solubility and eventually provoking an influx of CO2 to the atmosphere.
