Arctic permafrost research expedition started in Arkhangelsk
According to REGNUM news agency at the Northern Federal University, on September 17, 2019, the 78th expedition of the academician Mstislav Keldysh vessel departed from Arkhangelsk to the Arctic.
There are 65 scientists from various research institutes on the board; researchers from China participate in the expedition for the first time. Undergraduates and trainees from the Northern Federal University, Tomsk Polytechnic University and Moscow State University will have training and education in marine research together with experienced scientists.
«The main goal of the expedition is to study the flows and transformation of substances in the Arctic ecosystem. We will study the effects of coastal and underwater permafrost degradation. One of the issues is to study the effect of destruction of coastal permafrost on the transport of terrestrial organic substances into the ocean. This process is crucial. Before our study, it was believed that the main removal of organic substances is carried out by rivers. But over the past 20 years, it has been proven that coastal permafrost determines both the biochemistry of water and ecology. All this is important for understanding the freshwater balance of the Arctic Ocean», —the head of the expedition Igor Semiletov said.
During the expedition, degradation of underwater permafrost, which methane is present in, will be studied. Igor Semiletov noted that these processes caused the oxidation of water, which could be potentially dangerous for ocean dwellers and can disrupt food chains.
The expedition of the Academician Mstislav Keldysh will last until October 25, 2019. The research area of scientists - the Kara Sea, the Laptev Sea, the East Siberian Sea.
