Description
The ocean is very, very deep; light can only penetrate so far below the surface of the ocean. The ocean is divided into three zones based on depth and light level. The upper 200 meters of the ocean is called the euphotic, or "sunlight," zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles. Only a small amount of light penetrates beyond this depth. The zone between 200 meters and 1,000 meters is usually referred to as the "twilight" zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases. Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible. The aphotic zone exists in depths below 1,000 meters. Sunlight does not penetrate to these depths and the zone is bathed in darkness. PERCY JACKSON X FEM OC FANFIC TLT -> TTC (eventually)
