The assessment of the influence of energy dissipation (from the Archimedean force during lifting of gas bubbles) upon small scale processes of vertical turbulence of waters in the region of methane seeps areas is obtained on the base of studies, fulfilled in the NW Black Sea during the 48 cruise of the RV “Professor Vodyanitskii” in the framework of the International Program “European Rivers — Ocean Systems” (EROS2000) in August, 1995. We obtain that, on the scale of fields of gas releases, the dissipation of energy from the Archimedean force and from turbulent exchange are of the same order. The comparison of profiles of the vertical distribution of temperature directly in seeps of gas releases as well as in adjacent areas showed that the profiles are identical both in the higher mixed layer and below the thermocline, but there is a mean temperature reduction, equal to 0.62 °C, in the thermocline in seeps areas. The assumption is made on an ecological consequence of the lifting of gas bubbles into the photosynthesis zone, namely, increasing the trophic quality of waters on a small space scale.
