An international team of scientists has set a new record for the deepest known ocean fish. They were filming in the Mariana Trench â the deepest part of the ocean. The deepest part of the ocean is in the Mariana Trench (sometimes called the Marianas Trench), located in the western Pacific Ocean. At its deepest part, itâs just under 7 miles (6.831 miles / 10.994 km / 10,994 meters) deep.
The Challenger Deep, in the southern end of the Mariana Trench (sometimes called the Marianas Trench), is the deepest spot in the ocean. Its depth is difficult to measure from the surface, but modern estimates vary by less than 1,000 feet (305 meters).he Mariana Trench is a crescent-shaped trench in the Western Pacific, just east of the Mariana Islands near Guam. The region surrounding the trench is noteworthy for many unique environments.
