Scientists of Tomsk State University will study landscapes of the floodplain of the Ob River changed about forty years ago under influence of reclamation and will compare to their undisturbed analogues.
The station “Kaibasovo” will be the main base for the study; it was opened in the floodplain of the Ob River — one of the key sections of the ecological corridor running from the South to the North, from the Altai Mountainous to the Yamal Peninsula. The results of the research will allow assessing influence of anthropogenic and human factors in the past and modeling life of the ecological system of the Ob River in the future. The scientists also will study its participation in turnover of carbon — the main component of greenhouse gases.
The Ob River is the longest river in Russia; there are 3650 kilometers from its mouth to the source. The river flows through the valley and has a well-defined floodplain, which in the north can reach sixty kilometers in diameter. In spring under water there is a huge amount of vegetation, which rapidly decomposes and turns into “herbal infusion” rich with organic carbon. At that, nobody knows exactly what biogeochemical processes taking place there, as the director of the center “BioClimLand” Sergey Kirpotin says.
Landscape ecologists, geo-botanists, soil scientists, microbiologists, geochemists are studying functioning of the ecological system of the river, as niatomsk.ru reports. They will determine how people and climate changes influence on the biogeocoenosis of the river, in other words, on population of living organisms closely related to each other and with inanimate nature around them. Different tools will be used to research the floodplain of the Ob River — from geographic information systems to the newest equipment that allows measuring concentration of oxygen and carbon dioxide dissolved in water. With help of unmanned aircrafts the scientists will evaluate the river in dynamics: they will register the course of the flood and the dynamics of the surplus water.
