The troublesome shipping on the Northern Sea Route continues into the new year. Almost three weeks after the world's most powerful icebreaker arrived in the Chukchi Sea, none of the four vessels stuck in the area have broken out of the ice.

Parts of Northern Siberia were up to 7℃ warmer than normal in 2020. The warming is the most significant along parts of the North Siberian coast, and especially around the peninsulas of Taymyr and Yamal. This has been brought on, in part, by polar vortex on the Arctic coast.

A container ship froze into the waters of Yenisei Bay in Russia’s Arctic. Traveling from Dudinka to Arkhangelsk, the ship got stuck in ice on December 13. The crew battled icing, but was not in danger. Three weeks later, the ship was able to break free. According to Atomflot, the ship did not have necessary permissions to sail along this section of the Northern Sea Route.

Three weeks after it got stuck in Arctic sea-ice, the Sparta-3 makes it into open waters. The situation on board had been strained as reserves of fuel and water shrunk to low levels and the crew had to fight hard with icing. The military transport vessel did not have permission for sailing in the area.
