The increase of athmospheric CO2 concentration induce both a warning and a acidification of oceans and is linked with a higher
occurrence of strong waves and severe storms. The goal of our research is to determine the effect of these increase on (1) the
development and growth of animal individuals, (2)  their physiology, in particular the acid-base balance and skeletal formation, (3) the
biotic interractions framing littoral ecosysytems, and (4) the distribution of organisms, in particular in the southern Ocean.
