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 average depth of the ocean is about 12,100 feet (3,688 m). The lowest ocean depth on Earth is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench.
