Amderma, Russia: Submarine Cable Landing Point

Amderma is a rural locality in the Zapolyarny District of Nenets Autonomous Okrug, situated on the coast of the Kara Sea in Arctic Russia, near Vaygach Island and approximately 490 kilometres from the regional administrative centre of Naryan-Mar. Despite its remote location and small population, Amderma serves as a submarine cable landing point, hosting one submarine cable that traverses the Russian Arctic corridor.

The single cable landing at Amderma is the Polar Express, a domestically routed system connecting multiple points within Russia. As an Arctic coastal landing point, Amderma contributes to an emerging high-latitude submarine cable route that runs along Russia's northern coastline, a corridor distinct from the more established Pacific and Baltic cable routes that characterise other Russian landing points.

Cables Landing at Amderma

Polar Express is a submarine cable system measuring 12,650 kilometres in length, with a ready-for-service (RFS) date of 2022, listed as draft status. The cable connects landing points exclusively within Russia, making it a domestic submarine cable system. As one of the longest submarine cables landing in Russia, Polar Express represents a significant infrastructure undertaking along the country's northern maritime frontier, linking Amderma to other Russian endpoints along what is effectively an Arctic submarine route.

Regional Context

Within Russia's submarine cable infrastructure, which spans 13 cables across 28 landing points, Amderma ranks alongside Dikson as one of the landing points hosting a single cable. The majority of Russian landing points — including Anadyr, Ilyich, Nahodka, Petropavlovsk-Kamchatsky, and Sovetskaya Gavan — each host two cables. Amderma's position is therefore comparable to Dikson's, with both serving as single-cable termini within Russia's broader Arctic and Far Eastern submarine network.

Network Role

Amderma functions as a single-cable terminus on the Polar Express system, contributing one node to a domestically routed submarine cable that traverses Russian Arctic waters. The cable's exceptional length of 12,650 kilometres reflects the vast distances involved in connecting Russia's northern coastal communities, and Amderma's position on the Kara Sea places it at a geographically significant point along that route.

In the broader Russian submarine cable graph, Amderma represents the Arctic dimension of a national network that is otherwise concentrated along Pacific and Baltic coastlines. Its presence as a landing point, alongside Dikson, demonstrates that Russia's submarine cable infrastructure extends into high-latitude Arctic waters, connecting localities that are otherwise isolated by geography and limited by overland connectivity.
