   The ocean twilight zone is a layer of water that stretches around the globe. It lies 200 to 1,000 meters (about 650 to 3,300 feet) below the ocean surface, just beyond the reach of sunlight. Also known as the midwater or mesopelagic, the twilight zone is cold and its light is dim, but with flashes of bioluminescence—light produced by living ...

   The ocean twilight zone is incredibly hard to reach. At 400-3000 feet below the ocean’s surface, the twilight zone is far deeper than humans can easily explore. It also covers a vast area, spanning most of the world’s open oceans—so studying its ecosystem requires innovative new science and technology. Our team is developing powerful new ...

   It happens around the globe, every day, sweeping across the world’s oceans in a massive, living wave. Every night, fish, squid, plankton, and other mid-ocean dwellers begin their journey up to surface waters to feed. By daybreak, they will be gone again, headed back to the relative safety of deeper, darker waters.

   Scientists think that the largest animal migration on Earth may take place in the Twilight Zone, every day! At dusk, phenomenal numbers of creatures – fish, squid, shrimps – rise nearer to the surface to feed, using the dark of night to avoid predators. This would take the prize from birds, who see a huge annual migration of five billion.

   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 ...

   Why is the Twilight Zone important?

   • The ocean absorbs about a quarter of the carbon dioxide that human activities emit into the atmosphere. The twilight zone plays an important role in transferring carbon from surface water to the deep ocean, preventing it from returning into the air as a heat-trapping greenhouse gas.

   Why do animals live in the Twilight Zone?

   • Some organisms spend their lives in its shadowy depths, while others travel to and from the surface every day in the largest animal migration on Earth. Animals in the twilight zone help support the ocean’s food web and transport huge amounts of carbon from surface waters into the deep ocean, helping to regulate global climate.

   How does the Twilight Zone affect Earth's climate?

   • By migrating to and from the surface, eating, being eaten, dying—and even by pooping—organisms in the twilight zone transport huge amounts of carbon from surface waters into the deep ocean. That process, called the biological pump, plays an important role in regulating Earth’s climate.

   How much light penetrates the Twilight Zone?

   • 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.

   The ocean twilight zone is an important source of food for many marine animals, including valuable species like tuna and swordfish. It also plays an important, but little-studied role in taking carbon out of the atmosphere, which helps to regulate Earth’s climate. These two benefits alone are very important for humans, but they occur mostly ...
