What Is On The Deepest Ocean Floor

Back in 1977 a very interesting discovery was made on the deep ocean floor where no light penetrates.

What is on the deepest ocean floor.

It is located in the south pacific ocean on the northern side of the kermadec tonga subduction zone. At its deepest part it s just under 7 miles 6 831 miles. The deepest part of the ocean is in the mariana trench sometimes called the marianas trench located in the western pacific ocean. The ocean floor is called the abyssal plain.

It is crescent shaped and measures about 2 550 km 1 580 mi in length and 69 km 43 mi in width. Deep sea exploration has revealed varied landscapes which include volcanoes seamounts hydrothermal vents and cold seeps. Deep ocean hydrothermal vent ecosystems were discovered in 1977. Many of these newly discovered species live deep on the ocean floor in unique habitats that depend on plate movement underwater volcanoes and cold water seeps.

The pacific ocean has around 50 000km of convergent plate margins and most of the deepest point located around this place. 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. New species are discovered in the ocean each year by marine biologists and other ocean scientists. The maximum known depth is 10 984 metres 36 037 ft 25 metres 82 ft 6 825 miles at the southern end of a.

At 35 814 feet below sea level its bottom is called the challenger. 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. The tonga trench is the second deepest site in the ocean floor at 35 702 feet below the level of the sea floor. Features of the ocean include the continental shelf slope and rise.

The mariana trench or marianas trench is located in the western pacific ocean about 200 kilometres 124 mi east of the mariana islands. It is the deepest oceanic trench on earth. Today much of our exploration of the oceans happens using sonar and remotely operated vehicles. In the pacific ocean somewhere between guam and the philippines lies the marianas trench also known as the mariana trench.

Scientific research submersibles have explored the ocean s deepest trenches but most are designed to reach only the ocean floor. In fact there have been more missions into space than journeys down to the greatest depths of the oceans. 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.
