Severny Island

Severny Island is the northern island of the Novaya Zemlya archipelago in Arctic Russia and is one of the largest Arctic islands. It is notable for its extensive ice cap and its role in 20th-century military and nuclear testing.

The island’s interior is dominated by ice and glacial landscapes; rugged coasts and fjords line much of its perimeter. Coastal promontories and straits are the main points of access, and wildlife and polar environments are the principal natural attractions for scientific and expedition visits.

Severny developed as a military and testing area during the Soviet period. It was used as a site for nuclear weapons tests in the mid 20th century, including high-yield detonations at northern test locations.

Geographically it lies in the Arctic Ocean within the Novaya Zemlya chain, north of mainland Russia in the Barents Sea region. The island is remote from major cities; the nearest regional administrative centres are on the Russian mainland to the south and west.

• Access and restrictions: Access is tightly controlled and largely restricted because the archipelago has served as a military and nuclear-test zone; permits or organised trips are required for visits.
• Scale: The island is very large - Severny is the bigger of the two main Novaya Zemlya islands, with an area of roughly 48,900 square kilometres and extensive glaciation.

What to See #

• Severny Island Ice Cap: Large ice cap and glacier system occupying much of the island's interior, forming the bulk of its high ground and feeding outlet glaciers to the coast.
• Matochkin Strait: A narrow sea channel that separates Severny from Yuzhny Island and has been an important local navigation route.
• Sukhoy Nos (test area): A promontory on the island's northern coast that was used as a site for Soviet nuclear tests in the 20th century, including the 1961 high-yield test series.
