Responses of Sea-Ice Algae to Projected Ocean Acidification Levels
McMinn, A., Muller, M.N., Martin, A. and Ryan, K.G. 2014. The response of Antarctic sea ice algae to changes in pH and CO2. PLOS ONE 9: e86984.
To assess the likelihood of this possibility, McMinn et al. incubated brine algae - dominated by the unique ice dinoflagellate Polarella glacialis that they collected from McMurdo Sound (Antarctica) sea ice - under various carbonate chemistry conditions which they manipulated to produce pCO2 and pH ranges stretching from 238 to 6066 µatm and 7.19 to 8.66, respectively.
Brief and to the point, the four researchers from "down under" report "elevated pCO2 positively affected the growth rate of the brine algal community," and they conclude "projected increases in seawater pCO2 associated with ocean acidification, will not adversely impact brine algal communities." In fact, they suggest such communities may actually "benefit from the associated increases in CO2" that "are likely to be experienced by the end of the century."
