The idea of treading water, 50 meters down, in the middle of the ocean, in pitch black, makes me so anxious just sitting on my couch thinking about it...I couldn’t imagine just...sitting there, knowing that in every direction it effectively goes to infinity but I can’t see much beyond my hand in front of me.

Scuba diving is very much not a pursuit for some folks.

I've done a dive like this once, it is quite a trippy experience, you really do feel like you are just floating in empty space. You lose all sense of perspective. Even when you're swimming forward, it doesn't seem like you're moving at all.

Wondering if divers can determine up from down in the absence of surface light?

I’m guessing they could use the direction bubbles from their air supply are travelling...
