Structural features of the upper sedimentary sequence and seafloor topography in the coastal waters of the Rybachy Peninsula, Barents Sea

As part of geophysical studies on the structure of the upper sedimentary sequence and the topography of the Arctic seas' shelves, a geophysical survey has been conducted on a section of the seabed in the coastal zone of the Rybachy Peninsula (Kola Peninsula). The analysis of seismic-acoustic data has revealed three seismic complexes, separated by unconformity surfaces. These complexes are tentatively identified using methods of sequence stratigraphy and reflect events of Quaternary glaciation and interglacial periods. Bathymetric data have allowed for the identification of multiple traces of ice scouring, which are of both modern and relict origin. The internal structure of the sedimentary sequence is not always typical of glacial deposits but is distinguished by considerable diversity and significant lateral variability. Furthermore, numerous signs of degassing in the form of pockmarks are evident. However, the absence of gas flares and stable migration pathways suggests that these pockmarks are currently inactive or of an impulsive nature.
