Nicely done!

I was thinking, if man were to seek shelter under the ocean as the world climate continues in chaos or if indeed in the next 100 years, earth became unlivable due to extremes in temperatures similar to mars, we could indeed do this.

We could even in fact, have certain parts permanently affixed outside the surface of the water to draw in essentials such as oxygen, and perhaps if we needed heat, use geothermal heating below the oceans floor.

But all in all, the station would be deep enough to protect us from the extremes of the surface.

Interesting stuff to think about.
