Abstract. Basing on results of multibeam echsounding and acoustic profiling performed during expeditions of research vessels “Akademik Nikolai Strakhov” and “Akademik Boris Petrov” in 2018-2023 on two polygons and regional profiles regularities of occurrence of fluidogenic processes of the shallow part of Pechora Sea were established. Mapping of fluidogenic forms presented mainly by pingo-like features, acoustic anomalies in water, areas with different manifestations of fluidogenic processes in the upper part of section of quaternary sediments was performed. It was established that activity of fluidogenic processes, their manifestation in the section, occurrence of acoustic anomalies in water depend on geomorphological and geological-tectonic position of the area, presence of faults, thickness and type of permafrost and structure of quaternary deposits. Keywords: Arctic, degassing, fluidogenic landforms, fluidogenic processes, acoustic anomalies in water, permafrost
