Аннотация: The results of detailed geological and geomorphological studies in the waters of the Pechora Seausing a complex of hydroacoustic methods during the 52nd cruise of R/V Akademik Nikolaj Strakhov revealednumerous gas funnels (pockmarks) at the bottom of the Southern Novaya Zemlya Trench. These forms arewidespread over a considerable part of the bottom of the Barents Sea, but for the Pechora shelf, there is littleinformation about their distribution. The analysis of the seismoacoustic sections at the sites of developmentof gas funnels showed the presence of vertical chimneys in unconsolidated sediments of the Southern NovayaZemlya Trench, which allow gas to rise to the bottom surface and to escape into the water column with theformation of negative landforms, which is accompanied by the detachment of bottom sediments.
