The ice-gouging topography of the southwestern part of the Kara Sea bed is a result of the impact of icebergs and sea ice. During 52 cruise of the R/V Akademik Nikolaj Strakhov using a multibeam echo sounder we collected a representative data of key parameters of ice scours (location, orientation, depth, width) for the first time, which allows us t...
Using the results of multibeam echo sounding and seismic profiling performed during 2018—2019 on the R/V “Akademik Nikolay Strakhov” and all previously published data, a conceptual scheme of the pingo-like feature formation on the shelf of the Pechora Sea (south-eastern part of the Barents Sea between the islands of Kolguev and Vaygach) was develop...
This study analyzes seismicity within the shelf of the Barents Sea and the Knipovich and Gakkel ridges that surround it, and compares the spatial distribution of seismicity with the fault network as identified by seismic prospecting data. Kinematic characteristics have been obtained for the spatial migration of seismic activity. It is shown that th...
The morphology of the seafloor of the Madagascar Basin from Mauritius Island to the Southwest Indian Ridge (SWIR) is represented by a ridge-echeloned relief of the spreading basement. The azimuth of the relief differs by ~90° for the basin north of the SWIR and its wedge-shaped sublatitudinal rift system, separated by an abyssal escarpment. A genet...
The paper summarizes and systematizes available data on geological and geomorphologic structure of fluidogenic landforms on the Arctic shelves, in particular, pockmarks, pingo-like features, domes and craters. A small-scale map of the spatial distribution of fluidogenic landforms has been compiled. Geographical patterns of distribution of different...
Numerous landslides are located on the passive margin of Norway. According to the landslides number and the extent of their detachment zones, the margin can be divided into three segments (from south to north) — Scandinavian, Barents Sea and Svalbard. The fourth segment (Arctic) is the transition area located north of the Spitsbergen archipelago. I...
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...
Interpretation of the results of multibeam echo sounding and high-frequency seismic profiling, carried out as part of the voyages of the research vessels “Akademik Nikolay Strakhov” in 2018-2019, allowed us to establish that mud volcanic processes play an important role in the formation of pingo-like features on the Pechora Sea shelf. The process o...
Orthogonal wedging of the SWIR rift into the MOR formed a ridge spreading topography on the seabed with an orientation 90° different from the older one. The change in morphology is compared with the age of the MOR flank rupture and with the slowing down of the spreading rate. The absence of a deep mantle upwelling under the SWIR and the presence of...
Geomorphology of ping-like feaures of shallow Pechora sea
The results of detailed geological and geomorphological studies in the waters of the Pechora Sea using a complex of hydroacoustic methods in the 52 cruise of the R/V “Academic Nikolaj Strakhov” revealed numerous gas funnels (pockmarks) at the bottom of the Yuzhno-Novozemelsky trench. These forms are widespread on most of the bottom of the Barents S...

The article deals with the issues of the geodynamic evolution of the Kara–Barents Sea shelf and influence of structure-forming processes on the nature of relief formation. The aggregate data obtained allows us to assume that the relief of the western part of the Russian Arctic formed as a result of polycyclic processes of closing of the Proto-Atlan...
The article briefly describes the results of research during cruise 52 of the R/V Akademik Nikolaj Strakhov. Hydrophysical sounding was carried out, and water samples were taken using bathometers and bottom sediments were taken using a bottom grab and a gravity corer at complex stations. Geophysical studies have identified areas manifesting modern...
The emission of natural gas from the seafloor to the surface in shelf areas of the Arctic seas is of increasing interest among researchers. Recently, various types of acoustic instruments have been used to record streams of natural gas flowing out from the seafloor. Hydroacoustic and seismoacoustic equipment in various combinations was installed as...

Pingo-like features are weakly studied geological-geomorphological phenomena. In the south-eastern part of the Barents Sea during works of 38 and 41 legs of RV Akademik Nikolay Strakhov areas of development of these forms were studied using the mutlibeam echosounding and seismic profiling
A summary seismostratigraphic description of the Nansen Basin sedimentary cover was compiled
using data from the Norwegian sector of the Eurasian Basin and data interpretation from the Russian Arktika-
2011 project. It was found that sea level fluctuations had a significant impact on sedimentation processes in
the Arctic basin. Erosion processes on...
Reconstruction of the glaciation of the Barents Sea shelf is currently an urgent
scientific problem. In the south-eastern part of the Barents Sea during the work on the scientific program. On the 38th and 41st flights of the NIS "Academician Nikolay Strakhov" complex geological and geophysical work was carried out, including multibeam echosounding,...
The concept of glaciation of the Arctic region is currently the subject of discussion. To the greatest extent, this concerns the waters of the modern Arctic seas, in particular the waters of the Barents Sea. The conceptual dispute about the glaciation of offshore waters includes two theories. Proponents of continuous shelf glaciation (Swedsen et al...
По результатам анализа и интерпретации детальных акустических данных, полученных в экспедиционных работах 28 рейса НИС «Академик Николай Страхов» в 2011 году в южной части российского сектора Баренцевоморского шельфа, были выявлены основные генетические типы рельефа, а
также определены мощности четвертичного осадочного чехла в пределах исследуемой...
Флювиальные формы рельефа широко распространены на территории Западно-Арктического шельфа. Формирование флювиального рельефа в исследуемом регионе ассоциируется как с классическим развитием речных долин, так и с эрозионной деятельность ледниковых вод. Хорошая сохранность и выраженность в рельефе форм флювиального генезиса на дне Баренцева и Карског...
