An efficient method for measuring CO2 concentration in gassy lakes: Application to Lakes Nyos and Monoun, Cameroon
Lake Nyos Lake Monoun in-situ analysis dissolved CO2 gas self-lifting
2017/8/9
A simple and efficient method for measuring CO2 concentration of deep water of gassy lakes is proposed. This method is based on the gas self-lifting in a plastic hose that is deployed into deep water ...
