Abstract
From the results of three measurement cycles, it is shown that significant dynamics is observed in the spatial distribution of the amplitude and direction of carbon dioxide flux at the water reservoir of the Krasnoyarsk hydro power plant (HPP) in the summer-fall season. In June and August, the sink of carbon dioxide from the atmosphere to the water surface was observed all over the area of the water reservoir and at the territory downstream of the dam. In September, the entire water reservoir was mostly a source of carbon dioxide. It was found that in the three measurement periods the value of ΔРСН4 is positive, that is, in the summer-fall period the Krasnoyarsk water reservoir is a source of methane inflow into the atmosphere. The widest differences are observed just near the dam of the Krasnoyarsk HPP (from minimal in June to maximal in September).
