On September 28–30, 2025, the 3rd International Conference on Biology, Geology, and Environment of Hadal Trenches was organized by the Institute of Deep-sea Science and Engineering, CAS. This international symposium is currently one of the most significant platforms for sharing research results, new ideas, and plans to study the oceans at maximum depths. This year, the conference became an official event of the Global Hadal Exploration Programme (GHEP*), under the auspices of the UN Program «Decade of Ocean Science for Sustainable Development».
More than 100 scientists from 16 countries participated in the event. The three days of work included nine sessions covering the full spectrum of deep-sea research and five concluding panel discussions. The NSCMB FEB RAS was represented by Senior Research Scientist Dr. A.S. Maiorova, Leading Research Scientist Dr. M.V. Maliutina, and Deputy Director for Science Dr. V.V. Mordukhovich.
*GHEP is an international initiative aimed at the systematic study of the hadal zone - the regions of the ocean with the greatest depths, from 6000 to 11 000 m. GHEP develops interdisciplinary research using state-of-the-art equipment, including piloted, remotely controlled, and autonomous underwater vehicles. The program is based on large-scale international cooperation, bringing together researchers and institutions from around the world, ensuring equal participation, data sharing and access to infrastructure. By bringing together international practices and innovation, GHEP aims to transform disparate results into a common understanding of processes occurring in the depths of the ocean.
