Carbon dioxide, argon, nitrogen and methane clathrate hydrates: Thermodynamic modelling, investigation of their stability in Martian atmospheric conditions and variability of methane trapping

► The paper deals with the stability of clathrate hydrates at the surface of Mars. ► We compare experimental data with a thermodynamic model. ► We conclude hydrates to be stable at the surface of Mars, during winter. ► We provide an upper range for CH4 fluctuation due to trapping on seasonal caps. ► We provide an upper range for CH4 loss rate due to trapping on south permanent cap.
