What is Trench definition/concept/elaboration

The deepest enclaves in the oceans are known as ocean trenches or abyssal trenches. It is one of the most unknown places on our planet and, in turn, the most enigmatic. Some of these trenches reached 11 kilometers deep. Trench

These ecosystems have three particular characteristics: absence of sunlight, increased pressure and low temperatures.

Obviously, to study the depths of the ocean requires more advanced technology, especially the use of high-resolution sonars.

Ocean trenches pose a challenge to the scientific community

Ocean trenches are of high scientific interest for several reasons: Trench

1) the study of species and microorganisms that live there;

2) in these places, it is possible to experience the resistance of some materials, as the pressure on them is greater than usual;

3) knowledge of the carbon cycle;

4) understanding of climate change and underground currents.

The study of all these aspects converts ocean trenches into areas of great interest to the scientific community. From an economic point of view, the oil sector conducts exploration and extraction of oil in these areas. In any case, the scientific community believes that the study of the ocean’s depths is at a very early stage.

The Marianas Trench

The Challenger Chasm located in the Mariana Trench is the deepest place in the ocean and is located south of the Mariana Islands in the Pacific. The first exploration of this pit took place in 1875 and since then there have been several expeditions (in 2012, film director James Cameron was the first person to reach the deepest point of the Earth alone via a National Geographic-sponsored submarine). According to research, the exact depth is 11,034 meters and its deepest point is known as Challenger Deep, named after the first British expedition carried out in 1875 on the frigate HMS Challenger.

In the Marianas Trench we find all kinds of curiosity, such as large crustaceans, giant squid, jellyfish, various forms of plankton and unicellular beings that do not exist elsewhere on the planet. The animals that inhabit this place feed on the sediments that exist in the abyssal plains.

For marine biologists, it is a challenge to discover how different species have been able to adapt to such a hostile environment , as it must be taken into account that at this depth, no sunlight can reach. Trench
