Adding to Strange's point, the night vision from the conduit power does not seem to be working correctly under water even after the fog abates.
When the player is above water and still has night vision from the conduit, vision is crystal clear for quite a distance down to the ocean floor. However, underwater vision - even long after the fog effect should have lifted - is no different than without conduit power. I'll note that brightness is turned up with conduit power. It's just the distance that doesn't seem to be working.
