Researchers of the Moscow State University have created a database "Thermoabrasion of the seashores of the Russian Arctic", which contains information on qualitative and quantitative parameters characterizing the shores of six seas: Barents, Pechora, Kara, Laptev, East Siberian and Bering.

Thermoabrasion is the destruction of frozen shores as a result of thermal (thermal) and wave action. Almost a third of the entire coastline of the Arctic seas of Russia is subject to this process. To date, researchers from various scientific groups have published a lot of data on the destruction of the shores of the Arctic seas in various regions of the Russian Arctic. However, only the geographers of Moscow State University for the first time collected all the available knowledge into a single database "Thermoabrasion of the seashores of the Russian Arctic".

"Forming a database, the geographers of Moscow State University combined literary, archival and information obtained as a result of their own observations, which reflects the magnitude of the retreat or, conversely, accumulation (that is, "build-up") of the coast for various parts of the Russian Arctic over the past century," the report says.

The database allows you to analyze the spatial and temporal variability of the rates of coastal retreat along the Arctic coast of Russia, compare the rates of coastal destruction with various environmental features - lithological composition of rocks, geomorphological level, as well as hydrometeorological parameters - the duration of the ice-free period, annual sums of positive and negative air temperatures, the frequency of storms.

In the future, MSU geographers plan to supplement and expand the database in order to understand in more detail how the coastline of the Arctic seas changes over time.

Rosgeologia plans to continue drilling stratigraphic wells in the Laptev Sea for Rosneft next year after it first conducted such drilling in the Kara Sea this year, Boris Shumsky, director of the holding for offshore projects, told reporters.
Rosneft has drilled shallow stratigraphic wells in the north of the Kara Sea for the first time in the history of Arctic exploration. The project started in October. Its main task is to take a core sample for the subsequent acquisition of data on the geological structure and oil and gas potential of the North Kara basin. The drilling of stratigraphic wells as part of the Rosneft scientific expedition was carried out by the Rosgeologia vessel "Bavenit".
"The vessel can perform drilling operations at a water depth of up to one kilometer and drill wells to a depth of 500 meters. Actually, plans for 2021 already provide for deeper wells in the Laptev Sea. Our task is to drill wells up to 200 meters deep," - said Shumsky.
Director of the Department of Scientific and Technological Development and Innovations of Rosneft Alexander Pashali, in turn, noted that 10 wells were drilled in the Kara Sea as part of a scientific expedition and 6.5 tons of core were taken, which was sent to Innopraktika for further study. "These works, carried out this year, have shown their effectiveness. We expect to continue them next year in the eastern region of the Arctic and hope for the same successful implementation and great data from a scientific point of view," he said.
