If you dove down into the sea, and you could keep on diving. What would you see? We have only explored 5 percent of the ocean floor. 95 percent has not been explored. The prediction of how many ocean living forms we know of is 1 percent. What would we find? The Mariana Trench is 1,500 miles long. Only two people have descended to the planets deepest point, the Challenger Deep in the Pacific Ocean. The highest point on Earth is Mount Everest. If Mount Everest were dropped into the Mariana Trench, its peak would still be underwater for over a mile. 68 new species were discovered in 10 minutes. What could we discover in an hour?
Depending on the clarity of the water and where photosynthesis can no longer take place, this zone is from 200 meters to 1000 meters. Bioluminescence is prevalent here, helping creatures disguise their silhouettes from animals below them. The eyes of animals in this zone are often quite large due to the lack of light.
This Bathypelagic Zone is when the light can no longer pentrate the water. It depends and some areas like Honduras can be closer to 550 meters.This zone is also has very low temperatures and creatures have a very low organsmal biomass.
The Deep Scattering layer, the layer of fish, squid, crustaceans etc., that migrate eady day from the deep ocean to the shallower water is the boundary between the mesopelagic zone and the bathypelgic zone.
No photosynthesis takes place to replenish oxygen. This zone is calm and unaffected by sunlight and turbulent seas which are very far above. Since the water is so quiet, the only oxygen in the water is the dissolved oxygen that comes from were it originates from, the polar regions.
The nutrient level in this zone changes because this is were the dead biological meterials settle to the floor. The nitrogen, phosphorus, and silica is uniform and higher in the waters. Although the sea floor is devoid of oxygen, there is a food source from the collection of sediment.
Animals in this region, such as the anglerfish, tripod fish, and giant squid, can withstand pressures up to 11,000 psi. Many are blind, black or gray, and reproduce very slowly.
Not much is know about this zone, and it is found almost exclusively in deep ocean trenches.
This zone named after Hades has tremendous pressures making it humanity's least explored place. The deepest part, the Challenger Deep in the Mariana Trench is approximately 10,994 to 10,916 meters (35,755 to 36,070 feet).
