Decline in the aragonite and calcite saturation state At atmospheric CO2 concentrations of 560 ppm (projected in 20212021), most ocean surface waters will be undersaturated with aragonite Reduced calcification rates of calcifying species with reef erosion resulting in species extinction Large parts of

saturation state of seawater with respect to aragonite and calcite, the two forms of calcium carbonate (CaCO 3) com-monly produced by marine organisms. The saturation con-centration is roughly 1.5 times higher for aragonite than for calcite as is dictated by the solubilities of the two minerals. Hence, aragonite is more vulnerable to
Acidification and the Saturation State of Calcium Carbonate. CarbonateAcidification hampers the ability of marine organisms to form shells and skeletons of calcium carbonate (CaCO 3).The degree to which seawater is saturated with CaCO 3 is known as the "saturation state" (denoted by the Greek symbol omega, Ω). Saturated water has a saturation state (Ω) of greater than or equal to (≥) 1.0.

From these and other properties (nitrate, S, T) of the PML, we found that biological processes (photosynthesis and respiration) accounted for about 50% of the monthly variations in the carbonate ion concentration, [CO32−] and Ù, the saturation state of these waters with respect to calcite (ÙCa) and aragonite

Feb 19, 2021 · Similarly, the saturation state of seawater with respect to biogenic calcium carbonate minerals (calcite and aragonite) will also decline at a faster rate, suggesting that calcifying species may be adversely affected sooner in Puget Sound relative to open ocean populations .
The aragonite saturation horizon is found at ∼150 m in Barrow Strait; at 200 m in Baffin Bay, Davis Strait, and Hudson Strait; and at 2300 m in the Labrador Sea. This study provides baseline data of the saturation states for the waters of the CAA and the northwest Atlantic.
Climate change impedes scleractinian corals as primary
Coral reefs are among the most diverse and productive ecosystems on our planet. Scleractinian corals function as the primary reef ecosystem engineers, constructing the framework that serves as a habitat for all other coral reef-associated organisms. However, the coral's engineering role is particularly susceptible to global climate change.

Aragonite Mineral information, data and localities.
Aragonite Group. The Ca analogue of strontianite. The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite).It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions.
The inorganic carbonate chemistry of the southern Strait
A one-dimensional, biophysical, mixing layer model was modified to hindcast pH and aragonite saturation state (OmegaA) in the southern Strait of Georgia. The model skill in predicting spring phytoplankton bloom timing in previous studies was a key factor in its selection. Dissolved inorganic carbon (DIC) and total alkalinity (TA) were added as state variables, coupled to the existing nitrogen
