Strong winds and freezing temperatures in the Yenisei Gulf of the Kara Sea created overlapping, scale-like sea-ice patterns known locally as 'dragon scales.' Photos were shared by the first mate of the nuclear icebreaker Ural.

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.
