Introduction to the ocean's depths

Depths of the sea

The average ocean depth is 4.27 kilometers (14,000 feet), although there is a much deeper point called the Challenger Deep. This point lies under the western Pacific Ocean at the southern end of the Mariana Trench. It runs several hundred kilometers southwest of the island of Guam. The deepest point in the Atlantic Ocean is in the pit or trench north of Puerto Rico, which is 8.380 meters and 1.750 kilometers long.

3. The Challenger Deep

The Challenger Deep is the deepest point, known to date, in the ocean, being over 11,000 meters deep.Located in the Mariana Trench in the heart of the Pacific Ocean, it has only been explored by Swiss inventor Jacques Piccard and US Marine Don Walsh in 1960, filmmaker James Cameron in 2012, and Victor Vescovo, a record-breaking businessman, reaching 10,928 meters deep.

4. Who lives in the deep sea?

Ocean dwellers

At 11,000 meters deep, it may seem complicated for species to survive. With more than 1,000 atmospheres, 4 degrees of temperature and total darkness, there, in addition to a lot of human pollution, in the words of Victor Vescovo, we can find xenophyophores, which are capable of withstanding such extreme conditions. These beings are sponge-shaped microorganisms and are believed to play a key role in the sediment cycle deposited on the seabed.

5. More visits to the Moon that to the bottom of the sea

It is true that visits to space and the moon have been much more proactive than those to the sea floor. The last explorer was a robot that mimicked the shape of a snail and reached 10,900 meters deep.

Specifically, we have visited the moon 8 times more than the sea depths. Why? Both scenarios pose dangers because of the conditions of those places.
