I’ve been obsessed with this biome idea for Subnautica 2 based on a real-world phenomenon: submarine groundwater discharge. Basically, it’s where freshwater vents through underground caves into the sea. But instead of just one tiny spring, imagine a massive cluster of them forming an entire freshwater 'oasis' in the middle of the salt water.

The visuals would be incredible. Because of the way the fresh and salt water mix—called a halocline—the whole area would have this shimmering, unstable look that messes with your depth perception and visibility. It’s not just a backdrop, though; it’s a total survival shift. You’d have specialized creatures that thrive in the fresh pockets but take damage if they hit the salt water, and vice versa. Some predators might even use these springs like a highway system to dart around the map.

From a gameplay perspective, it feels so grounded in science but offers such cool new mechanics. You could drink directly from the vents to survive, but you’d have to deal with weird acoustics and muffled movement. It would make the ocean feel even more alive and unpredictable."

Also imagine a manati like leviathan

Btw for the love of me i cannot find the artist who made the image above. I dowloaded from some-where and forgot to note the artist down so if you know them please tell me and also sorry for my grammar.

"Update: Apparently, the image I used was made using AI? I don't know if it truly is AI; I had the body of this post saved on my phone for a few weeks (3 or 4). Alongside the text, I had saved the image, which was from a speculative biology website in the aquatic section. I don't remember the author, the name of the art, or the website. I found the website after searching for speculative biology artwork; I ended up with an image, and when I clicked it, I was sent to a gallery where I found the art. Whether or not it is AI is unknown to me, so I guess I’m sorry?

​But anyway, AI image discussion aside, I hope you liked my idea for a new biome.

​P.S. Yes, I know the shark had multiple fins in the image."
