Abstract. As a result of the Arctic Floating University-2023expedition, the landform was studied and sections of formations of the Barents-Kara region discussion in age and genesis were tested - in the area of the polar stations Bely Nos (Yugorsky Peninsula), Marresale (Yamal Peninsula), Sopochnaya Karga (Western Taimyr), geomorphological observations were carried out on the Novaya Zemlya archipelago (Jelaniya Cape). At the Wilczek Island (Franz Josef Land) marine Upper Holocene and probably Lower Holocene formations are described from Quaternary formations, composing a modern beach and terraces of different levels. In addition to the Quaternary, there are three morphologically different types of basalts: plateau-basalt, columnar basalts and pillow lavas (?), which were formed, respectively, under different conditions. Holocene marine sediments composing a terrace up to 1.5 m high were described and tested for the first time on Komsomolsky Island (Franz Josef Land).
