The Arctic Biome is a biome that may be added after Version 1.0 of Subnautica[1].

No images or Concept Art of the Arctic Biome exist, but it can be assumed that it would consist of a large ice cap which can be explored both above and below.

More information can be seen on this official Google Doc made by the developers, though much of this information is extremely outdated.
