Calcification: Sensitivities across phyla and ecosystems Theme
summaryOverarching questions - What are the cellular mechanisms
of calcification and decalcification in different marine
organisms, particularly with regard to ion transport to and from
calcification sites? - How will OA and pH stress affect
calcification at the level of organisms, communities and
ecosystems? Will concurrent temperature change modulate these
effects? - What changes will occur in the ultra-structure, trace
element partitioning, and isotopic signature of the shells and
skeletons of calcifyers in response to pH stress? - How does the
changing water column chemistry influence carbonate dissolution
and deposition in sedimentary systems? - Are past OA events
(e.g. in the Cenozoic) useful analogues for projected future OA
in their effects on calcifying organisms? Is the performance and
sensitivity of past and present calcifyers comparable, and does
this information help to assess the future? Calcification, the
precipitation of calcium wi
