Concentrations of methane (CH4) in marine water of the Sevastopol Bay were measured during different seasons of 2017–2018 and its emissions from water to the atmosphere were calculated. The CH4 content in water was measured by headspace method using the HP 5890 gas chromatograph. The CH4 surface concentration varied over a wide range, from 2 to 210 nmol L–1, and the CH4 saturation level was 61 to 6814% as compared to the equilibrium values. It was found that CH4 concentration depends on the seas
