The website of the National Training Foundation "Flagship Universities of Russia" reported that an authoritative scientific journal published the results of a joint research of scientists from L.V. Kirensky Institute of Physics, Krasnoyarsk Research Center, SB RAS and the Laboratory of Physical Problems of Monitoring of Agricultural Systems of Altai State University.

The International Journal of Remote Sensing, published by Taylor & Francis Group, the oldest UK publishing company, published an article entitled “A dielectric model of thawed and frozen Arctic soils considering temperature, texture and dry density and frequency of electromagnetic field oscillations” summarizing the results of many years of work of the research team of L.V. Kirensky Institute of Physics, Krasnoyarsk Research Center, SB RAS and Altai State University.

The main result of the project is the creation of a new physical model of permeability for arctic soils. Using this model to process the results of remote sensing will help to more fully assess the state of the Arctic territory, the temperature and humidity of its soil, and monitor the response of permafrost to climate change.

One of the stages of the research work was the study of soil samples collected in the Arctic tundra of the Yamal Peninsula, which was carried out in the Laboratory of Physical Problems of Monitoring of Agricultural Systems, created on the basis of AltSU together with L.V. Kirensky Institute of Physics, Krasnoyarsk Research Center, SB RAS.

“With the help of a coaxial waveguide, we carried out dielcometric measurements of samples of Arctic soils. In the course of the experiment, we investigated samples of different humidity, at different temperatures, and of different granulometric texture, collected in different areas of the peninsula. The studies have shown that the main parameter determining the maximum content of bound water in the soil is the granulometric composition of the soil, that is, the relative content of small particles in it. At the same time, the dielectric characteristics of free and bound water vary slightly depending on the type of soil and can be accepted regardless of the type of soil within the framework of our model”, specified Ilya P. Molostov, researcher of Altai State University.

Summing up, Ilya P.Molostov noted that the study of climatic problems of the Arctic, which L.V. Kirensky Institute of Physics, Krasnoyarsk Research Center, SB RAS is actively involved in, with Altai State University taking part in it, is relevant for both the Russian Federation and the whole world.
