Abstract (English):
The Small Kuril ridge – part of the island arc system of the Kuril Islands, located in the continental-ocean transition zone. The report notes the correlation between elements of the bottom topography of landscapes complexes and discusses their basic types. The most common elements of underwater slopes are bench – aligned, buried, ridge, with dense thickets of kelp and the community of echinoderms. Underwater ridge slopes with alternating asymmetrical ridges and troughs that separate them, inhabited by red algae, holothurians. In the bays of the main natural complexes – the central valley, the slopes on the sides of blocky, in the tops of the sedimentary dehydration. Straits between the islands have a width from hundreds of meters to tens of kilometers. The central part of the strait is plain with gravel-pebble material. Species of animals adapted for life in a hydrodynamically active zone – some mollusks, echinoderms. Common elements of islands shallow water – reefs. Their dismembered surface occupied by biocenosis of brown algae, holothurians, sea anemones. Accumulative plain, composed of sand and gravel material, which is located at depths of 20‒30 meters – the border of the coastal zone.

Малая Курильская гряда – часть островодужной системы Курильских островов, расположенная в континентально-океанской переходной зоне. Окруженные со всех сторон морем острова в течение года в одинаковой степени подвергаются воздействию волнения. Поэтому волновая экспозиция мало участвует в ландшафтной дифференциации береговой зоны. Одинаковые типы берегов можно встретить на разных сторонах островов. Большее значение в этом отношении имеет геологическое строение, устойчивость береговых пород к волновому разрушению.
