WebIn the open ocean, where light penetrates the deepest, there is sufficient light for photosynthesis at depths aboveabout 650 ft (200 m). This interval from the surface to 650 ft (200 m) is therefore known as the euphotic ( “ eu- ” = good, “ photo- ” = light) zone, or simply the photic zone. WebLight in the ocean decreases with depth, with minimal light penetrating between 200-1,000 meters (656-3,280 feet) and depths below 1,000 meters receiving no light from the surface. ... so light penetration is minimal. About 20 percent of primary production from the surface falls down to the mesopelagic zone. Consequently, the density or biomass ...
