This year scientists from Russia and France will be the first in the world to begin the study of bottom sediments of thermokarst lakes formed in the result of permafrost thawing in Yamal.
It will allow studying the past of water reservoirs and assessing their contribution into the global warming. This information was announced by the head of the center “BioClimLand” of Tomsk State University Sergey Kirpotin.
According to his words, the project involves scientists of Tomsk State University and the Observatory Midi-Pyrenees (Toulouse) of the French National Centre for Scientific Research (CNRS). The project is counted for three years, funding will make 13 million and 500 thousand rubles from the federal budget. The researches will be conducted on the station of Tomsk State University “Khanymey” in Purovsky district of Yamal-Nenets Autonomous Okrug located at the southern edge of the permafrost zone.
The scientists will take the sediments for studies; these sediments allow conducting historical retrospective analysis — what was before, how they were formed, accumulated, under what conditions. They will study also emissions of greenhouse gas, their accumulation in the past, because these sediments allow judging about the conditions of their forming and about many processes that took place during that time, as the scientist adds.
Sergey Kirpotin underlines that the results of the research will allow making correct forecasts, including for the future. The analysis of the past, the present and the forecasts for the future are very important for building models for the future, including climate ones, as he explains.
First of all, the scientists will study emissions of greenhouse gas. Now it is unknown how much organic carbon is accumulated in the bottom sediments of these lakes, and therefore, there are no ideas about its reserves in general, what is not considered in modeling of climate processes in the future. Ideas on carbon reserves will allow making more accurate forecasts: how much of them can be released, if, for example, it becomes warmer on several degrees.
The scientists not only take samples, but also conduct complex experiments on modeling of poorly studied processes. For example, fires in tundra became more frequent. Nobody conducted their research, so it is unknown what happens. And the scientists make models of these processes, as the specialist says.
Besides, prominent foreign scientists will arrive to the station of Tomsk State University within the International Network for Terrestrial Research and Monitoring in the Arctic INTERACT 2, which is financed by the program of the European Union “Horizon 2020”. Russia in this project is represented with four organizations, including Tomsk State University, as TASS reports.
