Sentences with phrase «coastal aragonite»

Not exact matches

The results of this study and of Feely et al. (2008) for the coastal North Pacific and Orr et al. (2008) for the Arctic show that undersaturation of surface waters with respect to aragonite is likely to become reality in a few years only.

Numerous peer - reviewed publications describe evidence that ocean temperatures are rising and ocean chemistry, especially pH, is changing.5 New observational data from buoys and ships document increasing acidity and aragonite under - saturation (that is, the tendency of calcite and aragonite in shells to dissolve) in Alaskan coastal waters.

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).
