Abstract

Some of the important atmospheric gases are added to seawater from the atmosphere through the constant movement of the sea surface by wind and waves. The amount of CO 2 dissolved in saturated seawater is unusually high. Oceans have a large storage capacity for (anthropogenic) CO 2. Direct discharge and sequestration of captured CO 2 in the deep ocean has been considered as a means to mitigate global warming. New CO 2 solubility measurements in seawater at high pressures, various temperatures, and salinities were presented. Using the fugacity of CO 2 at given values of temperature and the equilibrium pressure of full system, the fugacity coefficient of CO 2 and Henry's law for CO 2 solubility were calculated. The CO 2 solubilities in seawater in dependence of temperature, pressure, and salinity were analyzed.
