E-Mail Young scientists of Tomsk Polytechnic University as a part of the team of Arctic researchers have studied pore waters in three areas of methane release on the surface. They first managed to define in details the composition of pore waters in the cold methane seeps of the Eastern Arctic seas. The research findings are published in the Water academic journal. The research was based on the samples obtained during the Arctic expedition aboard the research vessel "Akademik Mstislav Keldysh" in 2019. The scientists and students from 12 scientific institutions, including Tomsk Polytechnic University, Moscow Institute of Physics and Technology, Lomonosov Moscow State University, the Research Center of Biotechnology of the Russian Academy of Sciences, the Vernadsky Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences, the Zhirmunsky National Scientific Center of Marine Biology of the Far Eastern Branch of the Russian Academy of Sciences and others took part in the expedition arranged by the Shirshov Institute of Oceanology of the Russian Academy of Sciences jointly with the Ilichev Pacific Oceanological Institute of the Far Eastern Branch of the Russian Academy of Sciences.
