Sentences with phrase «reduce aragonite»

The Southern Ocean is predicted to be the first place where this acidification will reduce aragonite concentrations to below saturation point, by the year 2100 [41].

Not exact matches

Not only do increased ocean temperatures bleach coral by forcing them to expel the algae which supplies them with energy (see photo at left)[viii], but increased ocean CO2 reduces the availability of aragonite from which reefs are made.

• Rising acidity: Rising levels of CO2 in the oceans are altering ocean chemistry and increasing the acidity of ocean water, reducing the saturation level of aragonite, a compound corals need to build their skeletons.

These geologically ancient, long - lived, slow - growing and fragile reefs will suffer reduced calcification rates and, as the aragonite saturation horizon moves towards the ocean surface, large parts of the oceans will cease to support them by 2100 (Feely et al., 2004; Orr et al., 2005; Raven et al., 2005; Guinotte et al., 2006).
