Deep Sea Floor

Deep sea mining works by having vehicles on the ocean floor dig directly into the seabed and this process releases silt clay and other sediments that are immediately carried away by the flow of.

Deep sea floor. These pools are dense bodies of water that have a salinity three to eight times greater than the surrounding ocean. The ocean floor is called the abyssal plain. The deep sea or deep layer is the lowest layer in the ocean existing below the thermocline and above the seabed at a depth of 1000 fathoms 1800 m or more.

Below the ocean floor there are a few small deeper areas called ocean trenches. Little or no light penetrates this part of the ocean and most of the organisms that live there rely for subsistence on falling organic matter produced in the photic zone for this reason scientists once assumed that life would be sparse. It has a capacity of twelve pokémon all of which are either obtainable in silver trench or evolve from pokémon found there.

Deep sea exploration has revealed varied landscapes which include volcanoes seamounts hydrothermal vents and cold seeps. At depths of over 10 000 feet and covering 70 of the ocean floor abyssal plains are the largest habitat on earth.

In fact there have been more missions into space than journeys down to the greatest depths of the oceans. Deep sea sediments the ocean basin floor is everywhere covered by sediments of different types and origins. So much more than you might think.

The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover. For deep sea brine pools the salt can come from one of two processes. Features rising up from the ocean floor include seamounts volcanic islands and the mid oceanic ridges and rises.

The dissolution of large salt deposits through salt tectonics or geothermally heated brine issue. The deep sea is a relatively mysterious and unknown part of the earth as only about 1 of the ocean floor has been explored by humans. Six gill sharks like this one off the coast of vancouver cruise the ocean floor during the day sometimes as deep as 8 200 feet 2 500 meters then move toward the surface at night to feed.
