Calcification and ocean acidification- From laboratory to geological time scales
This session seeks data on calcification responses to ocean acidification through the largest possible range of carbonate chemistry, as well as to bridge the time scales of laboratory experiments and geological variations, to improve insight into the likely responses of organisms and ecosystems to the oceanic uptake of anthropogenic CO2 over the coming decades and centuries. The geological record allows insight into natural climate experiments beyond the instrumental record, although the organisms and oceanographic settings may differ from the modern ocean. Laboratory manipulations define physicochemical states much wider than present or past ocean settings but short durations often leave questions over the organisms’ long-term adaptation potential. This session seeks to compare the sensitivities inferred from laboratory and natural experiments and to define indices of calcification applicable to experiments and the fossil record. Can we identify additional thresholds in carbonate chemistry analogous to those anticipated for the high-latitude oceans?
The Ocean Sciences Meeting will be held in Portland, Oregon, February 22-26, 2010. The abstract submission deadline is October 15, 2009. More information.
