While it is a very important point for the lay person to know that the acidification of the ocean by CO2 (it combines with water to produce dilute Carbonic Acid) can reduce the effectiveness of the Calcium Carbonate processes at sequestering Carbon (and can even reverse it, by dissolving Calcium Carbonate), your model chemistry seems quite simplistic.

Carbon dioxide dissolves into seawater and changes to carbonic acid, which lowers the water's pH. This in term dissolves the calcium carbonate in the skeletons of corals (as well as some free - floating plankton).

The acid reacts with calcium carbonate in the shell and dissolves it, leaving just the membrane behind.

Most studies have concluded that sea animals with calcified shells or skeletons, such as starfish, will suffer as carbon dioxide from burning fossil fuels dissolves in the sea, making the water more acidic and destroying the calcium carbonate on which the creatures depend.

Excess carbon dioxide enters the ocean, reacts with water, decreases ocean pH and lowers carbonate ion concentrations, making waters more corrosive to marine species that need carbonate ions and dissolved calcium to build and maintain healthy shells and skeletons.

But they conclude that marine organisms with skeletons made of high - magnesium calcite may be especially susceptible to ocean acidification because this form of calcium carbonate dissolves more easily than others.

Ocean acidification can negatively affect marine life, causing organisms» shells and skeletons made from calcium carbonate to dissolve.

• Safe: free of disease - causing microorganisms (bacteria, viruses, spores); heavy metals; chemicals from industry and agriculture; pharmaceuticals; disinfectants and related by - products; radioactivity; and synthetic fluoride; • Fresh: neither salty nor stagnant; • Clean: physically, biologically and chemically; • Natural: coming from a pristine mountain stream, glacial river or fresh spring; • Hydrating: water with low surface tension and thus better hydrating; • Mineral balanced: contains a wide variety of minerals including trace minerals, excellent ionic activity (Total Dissolved Solids ~ 300 ppm), including cations such as calcium, magnesium, potassium and sodium; and anions such as nitrate, chloride, bicarbonate, sulfate and carbonate.

The algae absorb both carbon dioxide and calcium dissolved in water, which then react to form calcium carbonate, which provides a limestone scaffolding for further expansion.

[OOOPS; this nonlinear effect puts their «alternative concept» into the realm of Trump administration «alternative facts» — BD] Although the deep ocean could dissolve 70 to 80 % of the expected anthropogenic carbon dioxide emissions and the sediments could neutralize another 15 % it takes some 400 years for the deep ocean to exchange with the surface and thousands more for changes in sedimentary calcium carbonate to equilibrate with the atmosphere.

Re # 92 The carbonate compensation depth (the depth below which calcium carbonate dissolves) is shallow in polar waters, so calcium carbonate sediments are virtually absent on the arctic seabed.

Intuitively, it might be expected that the precipitation of calcium carbonate would decrease solution pCO2 and dissolution of calcium carbonate would increase pCO2 because total dissolved inorganic carbon (DIC) concentrations and total alkalinity (TA) change in this manner.

«Southern Ocean acidification via anthropogenic CO2 uptake is expected to be detrimental to multiple calcifying plankton species by lowering the concentration of carbonate ion (CO32 − to levels where calcium carbonate (both aragonite and calcite) shells begin to dissolve.

Corals, shellfish, and other marine creatures made of calcium carbonate are threatened by ocean acidification, a consequence of rising atmospheric carbon dioxide levels increasing dissolved CO2 in the ocean.
