众所周知，二氧化碳在海水中的溶解度在较低的温度下会增加，但很少有研究考察二氧化碳在零度以下（摄氏度）海水和海冰盐水中的溶解度。第一次在零度以下的温度和盐度下测定了CO2在浓NaCl溶液中的热力学亨利定律常数（K-H），这些温度和盐度类似于极地和次极地海洋中的冰冻圈海水和海冰盐水环境。在本研究的温度和盐度范围内，K-H的温度（T，开尔文）依赖性（263
The solubility of CO2 in seawater is known to increase at colder temperatures, but few studies have examined the CO2 solubility in seawater and in sea-ice brines at sub-zero (Celsius) temperatures. The thermodynamic Henrys Law constant (K-H) for CO2 in concentrated NaCI solutions was determined for the first time at sub-zero temperatures and salinities resembling those of the cryospheric seawater and sea-ice brine environments in polar and sub-polar oceans. The temperature (T, in Kelvin) dependence of the K-H within the temperature and salinity ranges of this study (263
