Response of the coccolithophore Emiliania huxleyi to future ocean acidification conditions: from gene expression to physiological rates
After the Industrial Revolution, the CO2 produced by humans and emitted to the atmosphere has been increased exponentially. As a result of this CO2 increase, the ocean surface absorbs one third of the carbon emissions per year. In this investigation planning we propose to test the CO2 effects in dif...
