Norilsk Nickel organizes winter field study of permafrost for students

06 february 2024

The polar branch of Norilsk Nickel is organizing the second winter field school to research permafrost in Taimyr for students of Russian universities.

A year ago, students from Norilsk's Polar State University went to Zvenigorod in the Moscow region, and this year students from Moscow State University will visit the Arctic zone.

A joint team of students from the Faculty of Geography of Moscow State University and the Department of Civil Engineering of Polar State University conducts research in the field of geocryology and glaciology. Having studied the features of snow redistribution near the buildings of the port city of Dudinka, students began researching residential areas of Norilsk, where the role of mechanized snow removal is very important.

The participants of the winter field school will compare the obtained data with the results of unique studies of snow deposits in the city that have been collected since 1986. As a result, researchers will be able to conclude how the density and volume of snow changes over decades, and assess the extent of permafrost degradation.
