Abstract
Mesocosm experiments conducted for ecological purposes have become increasingly popular because they can provide a holistic understanding of the biological complexities associated with natural systems. This paper describes a new outdoor mesocosm designed for CO2 perturbation experiments of benthos. Manipulated the carbonate chemistry in a continuous flow-through system can be parallelized with diurnal changes, while irradiance, temperature, and nutrients can vary according to the local environment A target hydrogen ion activity (pH) of seawater was sufficiently stabilized and maintained within 4 h after dilution, which was initiated by the ratio of CO2 saturated seawater to ambient seawater. Specifically, pH and CO2 partial pressure (pCO(2)) levels gradually varied from 8.05-7.28 and 375-2,691 mu atm, respectively, over a range of dilution ratios. This mesocosm can successfully manipulate the pH and pCO(2) of seawater, and it demonstrates suitability for ocean acidification experiments on benthic communities.
