TSU is exploring a swamp river saturated with dissolved carbon


The staff of the TSU Bio-Geo-Clim laboratory, with the support of the Russian Science Foundation, is studying the climate-regulating role of the Siberian rivers Ob and Lena, and in particular, assessing their contribution to the formation of the greenhouse effect. Researchers recently began work on the river Ket, which is a tributary of the Ob and originates in carbon-rich marshes. At the new site, scientists conducted a sampling to measure the concentration of dissolved carbon in water, and in addition, they will estimate the extent of its release into the atmosphere. Samples will be analyzed by five research centers in Russia and France.

- The subject of dissolved carbon in the context of global warming is worrying many countries, especially those that are below sea level, says Sergey Vorobyov, a researcher at Bio-Geo-Clim. - The reason is that emissions of this element are increasing, in part because of melting of the permafrost, which stores large stocks of dissolved carbon. Rivers also make a significant contribution to these processes because they accumulate this element and transport it to the world’s oceans. How large their role is in the formation of the greenhouse effect is not precisely known; large-scale studies have not previously been conducted.
