The Arctic Kelp Forest is a biome featured in Subnautica: Below Zero.

Description

The Arctic Kelp Forest supports a plethora of life forms, most of which are passive. Among the lush Creepvines, Pinnacarids can be observed occasionally preying on smaller fauna species, like the Arctic Peeper or the Boomerang, though they do not spawn within the biome. The landscape of the area can be harsh, sometimes featuring rocky arches and deep crevices. The seabed is usually sandy or rocky, and is covered in patches of greenish yellow seagrass.

The Arctic Kelp Forest borders mostly around Twisty Bridges area, Sparse Arctic and the Thermal Spires. The biome also possesses its own cave system.

Trivia

In early versions of the game, this biome was the only biome to play music, however, the music was taken directly from Subnautica. The music likely was the default playlist for music, and could have potentially been left in by accident.

Notably, in early prototype footage, horns can be heard from the surface, which are the exact same sounds used in early versions of Subnautica, both in the Pax 2014 Build, in the Koosh Zone (later renamed to Bulb Zone), and in the unused Arctic Biome. The Pax 2014 Build, Koosh Zone, and Arctic Biome all featured the exact same music included in the Kelp Biome as well interestingly enough.

A possible theory for both of these facts is when creating a playlist for ambience and music, the default options included the horn surface ambience, as well the default music heard in the three biomes. Later on, whether it was due to the ambience being removed from/replaced in the files, a developer changing the surface ambience in the Kelp Forest, or the programming for how ambience is managed being adjusted, the surface ambience would be the same as anywhere else by the time Early Access would release.
