The Epipelagic zone is the surface layer of the ocean that extends over 200 meters or 656 feet long. The water along the bottom of this zone is actually devoid of oxygen, making it a death trap for organisms unable to return to the oxygen-rich water above. region between the high and low tide of an area. It is the pitch-black bottom layer of the ocean. Algae that live in the epipelagic zone are responsible for much of the original food production for the entire ocean and create at least 50% of the oxygen in the atmosphere (both through photosynthesis). Many of these bacteria, for example, convert hydrogen sulfide to sulfate and store the energy extracted from this reaction as chemical energy by synthesizing carbon-based compounds. Every ten meters of depth increases the pressure by about one atmosphere (about 14.7 pounds per square inch at sea level); abyssal pressures range between 200 and 600 atmospheres. The long, pinkish-colored hagfish, for example, can go as long as seven months without eating because their metabolism is so slow.
