The research was carried out by a team from the Institute of Oceanology of the Russian Academy of Sciences during the expeditions of the research vessels (RV) “Peleng” of the Sevastopol branch of the State Oceanographic Institute and “Professor Vodyanitsky” of the Federal Research Center InBYuM (115th, 116th, 124th and 126th voyages) in 2018–2023 in accordance with the Plan of Marine Expeditions on Research Vessels of the Ministry of Education and Science of Russia. At the same time, the tasks of depth measurements, continuous seismic profiling (CSAP) and acoustic sounding of sedimentary deposits, as well as panoramic survey of the bottom surface using a side-scan sonar were solved. The objectives of the study included: firstly, obtaining new geological and geomorphological data on the history of the development of the Crimean Peninsula shelf, necessary for restoring poorly studied stages of the paleogeographic history of the formation of the continental margin of Crimea in modern times, which will clarify the existing ideas about the change in the Black Sea level, and secondly, obtaining new geological and geomorphological data on the paleogeomorphology of the Crimean Peninsula shelf, which will clarify the position of the ancient hydrographic network and establish the connections of coastal and subaqueous morphostructures. In the process of interpreting continuous seismoacoustic profiling (CSAP) data, anomalous areas identified with gas accumulations were identified in the bottom part of the section.
