At what depth is the ocean dark?
Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible. The aphotic, or “midnight,” zone exists in depths below 1,000 meters (3,280 feet). Sunlight does not penetrate to these depths and the zone is bathed in darkness.

Is there light at the bottom of the ocean?
The ocean is very, very deep; light can only penetrate so far below the surface of the ocean. As the light energy travels through the water, the molecules in the water scatter and absorb it. … Below the photic zone, from 200 to 1,000 meters, is the aphotic (a meaning without and photic meaning light) zone.
