The deep water methane inventory of the eastern Gotland Basin showed a seasonal pattern, with concentrations increasing during spring/summer and decreasing during fall/winter as a direct result of the seasonal varying vertical turbulent diffusivity. The western Gotland Basin showed no clear correlation between the seasons and the observed deep water methane variability.
