The scientists hope to gain more insight into this by exploring how past changes in seawater pH have impacted these organisms, but also through further field and laboratory studies testing the effect of ocean acidification
on these calcifiers.
Not exact matches
Ocean acidification is therefore one of the most important research areas regarding the effects of elevated CO2
on benthic marine
calcifiers and the marine ecosystem in general.
Up to now previous investigations focused
on calcite or aragonite saturation state as indicators of
calcifiers thresholds, which may completely miss the vulnerability of many
calcifiers.
Previous CO2 rises
on Earth happened so slowly that the accompanying ocean acidification was relatively minor, and ammonites and other planktonic
calcifiers were able to cope with the changing ocean chemistry.
Workshop report: Impacts of Ocean Acidification
on Coral Reefs and Other Marine
Calcifiers, A Guide for Further Research (pdf, 8.9 M)
We do not know what changing ocean chemistry will do to marine biota (other than some
calcifiers) and especially we do not know what the long - term chronic effects will be
on ecosystems.
Because if not, «Laboratory experiments revealed that ocean acidification has negative impacts
on the fertilization, cleavage, larva, settlement and reproductive stages of several marine
calcifiers, including echinoderm, bivalve, coral and crustacean species.
To date, much of the focus of ocean acidification research has been
on the response of
calcifiers, both algae and invertebrates, to the changing carbonate system, with a particular preoccupation
on one property: the hydrogen ion concentration [H +], which is frequently reported as pH owing to the relative ease of its measurement.
