Exploration of the Mariana Trench.

The Mariana Trench is a small area in the western Pacific Ocean where the bottom is the deepest. It was discovered in 1875 by a British expedition on the ship called Challenger, A) ____________. The first estimate of the depth of the Mariana Trench made by this ship showed 8184 meters. Since then, this value has been continuously refined. The difficulty of accurate determination was due to the imperfection of methods, B) ____________. Therefore, launching a submersible to such a depth requires a special material for the hull.

For more than a century of research scientists have received different values for the depth of the Mariana Trench. The maximum depth was established by Japanese specialists in 1984, C) ____________. An important role in the study played a Soviet expedition on the ship "Vityaz". During it, 24 species of animals were brought on board, D) ____________.

In 1960, the first human dive to the bottom of the Mariana Trench took place. American Don Walsh and Swiss Jacques Piccard descended to the bottom in a bathyscaphe and spent 20 minutes there. The second descent took place only 35 years later, and in 2002 experts found here unknown single-celled organisms E) ____________. In 2012, the famous Canadian director James Cameron made a descent into the Mariana Trench. Work on the design and construction of the bathyscaphe took 7 years, F) ____________.

Today, studies of the Mariana Trench continue, because they can give a more accurate understanding of the structure of the Earth's crust. Seismographic measurements are being actively carried out. However, descending to such depths is still a challenge for modern technology. Special apparatuses capable of operating at such high pressures need to be developed. In the century and a half since the Mariana Trench was discovered, fewer than ten people have been to its bottom. And the exact depth of the Mariana Trench is still unknown, G) ____________.

1) 10 of which were described for the first time
2) it was 10924 meters
3) that existed in an unchanged form for a billion years
4) as even the latest measurements have an error of several tens of meters
5) and it involved not only scientists, but also Cameron's own team
6) as well as the fact that the pressure at a depth of almost 10 kilometers is more than 1000 atmospheres
7) which had been converted from a warship for scientific research
