Sentences with phrase «seawater aragonite»

In addition, they state that there was «no significant correlation between calcification rate and seawater aragonite saturation (Ωarag)» and «no evidence of CO2 impact on bleaching.»

Not exact matches

Models suggest that if seawater becomes too low in aragonite, organisms with aragonite shells will dissolve.

The saturation state of seawater for a mineral such as aragonite is a measure of the potential for the mineral to form or to dissolve.

Here we show that CaCO3 dissolution in reef sediments across five globally distributed sites is negatively correlated with the aragonite saturation state (Ωar) of overlying seawater and that CaCO3 sediment dissolution is 10-fold more sensitive to ocean acidification than coral calcification.

Changes in the carbonate ion concentration in seawater can affect the saturation state (and hence biological availability) of several types of calcium carbonate (e.g., calcite, aragonite, or high - magnesian calcite.

The aragonite calcifiers — such as the well - known corals Porites and Acropora — have molecular «pumps» that enable them to regulate their internal acid balance, which buffers them from the external changes in seawater pH.

Accordingly, upwelling of waters acidified by anthropogenic CO2 has led to a further decrease in surface pH, as reported in the eastern Pacific Ocean along the west coast of North America, from central Canada to northern Mexico, where shoaling of the layer of seawater undersaturated with aragonite increased the frequency and magnitude of coastal acidification associated with upwelling events (Feely et al. 2008, 2010).
