Rosneft Oil Company continues to study modern geological and geomorphological processes, including natural hazards, to determine engineering-geological conditions in the development areas of the Arctic seas and conceptual design. The relevance of the problem is defined by the scale of tasks and new challenges that Russia faces in the 21st century as it continues to develop the Arctic's resources in exceptionally complex and dynamically changing natural and climatic conditions. Special attention should be paid to the following potentially hazardous processes and features: pockmarks (craters formed on the seabed by gas emissions); gas emissions into the waters; gas accumulations that create seismic-acoustic anomalies in the upper layers of the sedimentary strata; neotectonic deformations; ice scours; and the activity of intense currents. Submarine canyons are also an important geomorphological element of the Kara Sea seabed. They are characterized by sharp changes in relief and the presence of active lithodynamic processes, including hazardous ones. The formation of fluvial relief in the region under study is associated with both the classical development of river valleys and the erosive activity of glacial waters. The results obtained in this study will allow the authors to determine the complexity of the engineering geological conditions and assess the associated risks, that may arise during hydrocarbon exploration and production projects of Rosneft Oil Company license areas in the Kara Sea, as well as develop measures to reduce their negative impact on the quality and safety of operations.
