Calcifiers

Marine Ecology Progress Series 417:171

Decreased pH may affect calcification by altering carbonate mineral thermodynamics and by effects on other physiological processes of marine calcifiers (Pörtner 2008).

A Review of Ocean Acidification and America's Response

Aragonite calcifiers (e.g., stony corals and shelled pteropods) and high-magnesium calcite calcifiers (e.g., coralline algae and sea urchins) are likely to be affected by ocean acidification more strongly than calcite calcifiers (e.g., foraminifera and coccolithophores).

7 A subsequent review noted that although this number is increasing, much of the literature remains uncertain and contains notable gaps, such as the exclusion of non-calcifiers and a focus on calcification and not other physiological processes that could be affected by ocean pH changes. 8 ...

International Commission on Land Use Change and Ecosystems

The best studied event occurred 55 million years ago when there was a rapid input of carbon into the atmosphere and oceans which was linked to major changes in marine plankton communities and the mass extinction of one group of marine calcifiers living on the sea bed 18.

Power Of pH.Final.4.07

Of great concern is the impact ocean acidification may have on ocean calcifiers like molluscs, corals and some plankton. Calcifiers absorb calcium (Ca 2+ ) and carbonate (CO 3 2-) from surrounding waters in order to build their shells and skeletons.

AFSC PROCESSED REPORT 2008-07

Corrosive waters reach shallower depths more so there than in any other ocean basin, especially in Alaska, and so impacts of ocean acidification on marine calcifiers will likely occur earlier there than in many other places.
