The studies have been concerned with the evaluation of methane transformation rates, the fluxes of methane across boundaries of the Black Sea system and the assessment of physical controls on the cycling of methane within the water column. The specific objectives of the work are: to assess general and regional peculiarities of the methane distribution in the Black Sea, its geological and microbiological sources; to further develop a model of vertical exchange in the Black Sea focusing on its application for the description of methane cycling by (i) incorporating exchange processes at the upper boundary of the bottom homogeneous layer (BHL); (ii) adding a non-stationary component to the background physical model; to evaluate the budget of methane (production, consumption rates and fluxes) for the water column; to parameterise bacterial production and consumption of methane under oxic and anoxic conditions; to numerically simulate cycling of methane in the oxic/anoxic water column of the Black Sea, its evolution in response to climate change and anthropogenic or natural eutrophication of the basin.
