The Mariana Trench was first measured by HMS Challenger in 1875 using sounding lines. The depth recorded by that method was 4,475 fathoms (8,184m).
The first sonar measurement was made by another oceanographic survey ship of the same name, in 1951. The depth reported by that expedition was 10,911 meters.

The Mariana Trench, the deepest part of the world's oceans, reaches a depth of approximately 10,994 meters. This measurement can vary slightly due to geological activity and advancements in technology, but 10,994 meters is widely accepted as the trench's depth.
The Mariana Trench in the Pacific with a maximum known depth of 6.8 miles
The trench is in the ocean. The 14 islands nearby are called the Commonwealth of the Northern Mariana Islands.
Hardly any organisms can survive in the Mariana Trench due to the pressures at that extreme depth. Xenophyophores, amphipods, sea cucumbers, snailfish and jellyfish are examples of organisms that live in the Mariana Trench.
The Mariana Trench is the deepest point in any ocean and is located in the Pacific Ocean.
