Saltwater/ocean if it makes a difference. On a clear day with no waves. If you were scuba diving, how far down can you be and still see well with only the human eye/no flashlights? (seeing other people, plants, and animals)

Also, if you were at the surface and looked down(with goggles on at the top of the water) how far down could you see?


The Epipelagic Zone ( the sunlight zone ) extends to approximately 660 feet this is the maximum depth that still receives a good amount of sunlight on a sunny day. The Mesopelagic Zone ( the twilight zone extends to approximately 3,300 feet this is the maximum depth that any sunlight can reach.
