How much light gets into the neritic zone?

The neritic zone, which extends from the low tide mark to the edge of the continental shelf, receives ample sunlight, allowing for significant photosynthetic activity. Typically, light penetrates to depths of about 200 meters in this zone, depending on water clarity. This abundant light supports diverse marine life, including various algae and phytoplankton, forming the base of the oceanic food web. Overall, the neritic zone is one of the most productive areas in the ocean due to its favorable light conditions.
