What is the epipelagic zone?
Quick Answer
The epipelagic zone is the sunlit upper layer of the ocean, extending from the surface down to about 200 meters.
The Full Story
This is the only ocean layer with enough light for photosynthesis, so it supports phytoplankton and most of the ocean’s primary production. It contains many familiar marine animals, including tuna, dolphins, sea turtles, and many sharks. Because it is warmest and best lit, it is also the layer where most fishing and surface marine activity occur. The health of this zone strongly affects global oxygen production and ocean food webs.
