Russia to create three-dimensional underwater permafrost map

In the fall of 2023, a comprehensive expedition will set off to explore the four Arctic seas.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. In August-November 2023, a comprehensive expedition will sail across four Arctic seas – the Kara, East Siberian, Chukchi and Laptev seas. Scientists intend to study the processes taking place on the shelf and create a three-dimensional map of underwater permafrost, the Tomsk State University (TSU) press service said.

The geography of research on the Global Changes in the Earth: Climate, Ecology, Life Quality topic is devoted to the study of the Arctic to model the climate and the consequences of warming. A large research group, which will include scientists from the TSU, the Pacific Oceanological Institute of the Far Eastern Branch of the Russian Academy of Sciences (POI FEB RAS), Moscow State University (MSU), the Institute of Permafrost Science of the Siberian Branch of the Russian Academy of Sciences, will go on a sled-tractor expedition to the coast of the Laptev sea.

Most of all, scientists are interested in the underwater permafrost top position. Its thawed zones can be of different depths, including through ones – in the latter case, massive emissions of bubble methane are observed. It is important for researchers to create their three-dimensional map, which is possible using the electromagnetic method.

“The scientific tasks that we are solving are the study of the mechanisms of transport and transformation of organic and terrestrial matter in general in the land-shelf-atmosphere system. We plan to conduct a complex of biogeochemical, geophysical and geological studies. They are aimed at identifying the mechanism of disruption of the carbon cycle main components depending on the permafrost state”, explained Igor Semiletov, a scientist from TSU and POI FEB RAS, one of the expedition organizers.

Earlier, the North Pole-41 expedition started research on a self-propelled ice platform. We also said that scientists are studying the adaptation of Arctic plants to cold conditions, while Nornickel and the Academy of Sciences summed up the results of the Big Scientific Expedition – a large-scale study of biodiversity in the territories where the company’s enterprises are located.
