   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.

   Not only is the Twilight Zone full of marine life, it is also crucial to how the ocean takes up and stores carbon dioxide from the atmosphere in a process known as the biological carbon pump. Without life in the ocean providing this pump we think atmospheric carbon dioxide concentrations could be 50% higher than they are even now.

   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 ...

   Humans receive two key benefits from the twilight zone: the removal of heat-trapping carbon dioxide from the atmosphere, and the support of commercially important fisheries in the surface waters. Potential future benefits include the harvest of twilight zone fish to produce fish meal for aquaculture operations or fish oil for human health supplements.

   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.

   What is the Twilight Zone?

   • 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 organisms. The region teems with life.

   Aug 21, 2018 · In fact, at least as far back as 1915, textbooks included discussion of the “decrease in the abundance of life from the sunlit surface layers, through the twilight zone, to the zone of darkness,” as was written in College Physiography.
