How much methane and CO2 do Siberian lakes gather during winter?


The study of carbon cycle is one of the major global research trends, as carbon is a part of active greenhouse gasses. In Russia, the field season is limited by weather conditions; few research groups analyze carbon balance during winter. For several years, TSU scientists have been monitoring the carbon level in water ecosystems. Recently, they have collected winter samples of the Ob River floodplain using new devices that can quickly and accurately determine the ecological properties of bodies of water.

“Lakes of the Ob floodplain are rich in organic matter and play an important role in the global carbon cycle, but it is still unclear what processes occur in lakes during winter,” says Lyudmila Borilo, executive director of the strategic academic unit Siberian Institute of the Future. “We organized a comprehensive winter expedition to the Kaibasovo research station to assess the main factors influencing biogeochemical cycles. We have determined the amount of CO2 gathered during the winter. The level is higher than in spring or summer. Now, we need to understand the sources of carbon in the water.”
