What is Ocean Acidifiion?

The Chemistry. When carbon dioxide (CO 2) is absorbed by seawater, chemical reactions occur that reduce seawater pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate chemical reactions are termed "ocean acidifiion" or "OA" for short. Calcium carbonate minerals are the building blocks for the skeletons and shells of many marine ...

Effectiveness of the addition of alkaline materials at ...

Many of the mine sites had overburden characteristics that made prediction of post‐mining water quality uncertain. Alkaline materials were applied at rates ranging from 42 to greater than 1,000 tons as calcium carbonate per acre. In addition, two sites that were mined and reclaimed without alkaline additives are included for comparative purposes.
