Volcanic carbon dioxide vents show ecosystem effects of ocean acidification
International audience The atmospheric partial pressure of carbon dioxide (p(CO2)) will almost certainly be double that of pre- industrial levels by 2100 and will be considerably higher than at any time during the past few million years(1). The oceans are a principal sink for anthropogenic CO2 where...

International audience The atmospheric partial pressure of carbon dioxide (p(CO2)) will almost certainly be double that of pre- industrial levels by 2100 and will be considerably higher than at any time during the past few million years(1). The oceans are a principal sink for anthropogenic CO2 where it is estimated to have caused a 30% increase in the concentration of H+ in ocean surface waters since the early 1900s and may lead to a drop in seawater pH of up to 0.5 units by 2100 ( refs 2, 3). Our understanding of how increased ocean acidity may affect marine ecosystems is at present very limited as almost all studies have been in vitro, short- term, rapid perturbation experiments on isolated elements of the ecosystem(4,5). Here we show the effects of acidification on benthic ecosystems at shallow coastal sites where volcanic CO2 vents lower the pH of the water column. Along gradients of normal pH ( 8.1 - 8.2) to lowered pH ( mean 7.8 - 7.9, minimum 7.4 - 7.5), typical rocky shore communities with abundant calcareous organisms shifted to communities lacking scleractinian corals with significant reductions in sea urchin and coralline algal abundance.
