  abstract = {{W}e studied the direct effects of {CO}, and related changes in seawater carbonate chemistry on marine planktonic organisms in a mesocosm experiment. {I}n nine outdoor enclosures (similar to 11 m(3) each), the partial pressure of {CO}2 (p{CO}(2)) in the seawater was modified by an aeration system. {T}he triplicate mesocosm treatments represented low (similar to 190 parts per million by volume (ppm{V}) {CO}2), present (similar to 410 ppm{V} {CO}2), and high (similar to 710 ppm{V} {CO}2) p{CO}(2) conditions. {A}fter initial fertilization with nitrate and phosphate a bloom dominated by the coccolithophorid {E}miliania huxleyi occurred simultaneously in all of the nine mesocosms; it was monitored over a 19-day period, {T}he three {CO}2 treatments assimilated nitrate and phosphate similarly. {T}he concentration of particulate constituents was highly variable among the replicate mesocosms, disguising direct {CO}2-related effects. {N}ormalization of production rates within each treatment, however, indicated that the net specific growth rate of {E}. huxleyi, the rate of calcification per cell, and the elemental stoichiometry of uptake and production processes were sensitive to changes in p{CO}(2). {T}his broad influence of {CO}2 on the {E} huxleyi bloom suggests that changes in {CO}2 concentration directly affect cell physiology with likely effects on the marine biogeochemistry.},
