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 mean depth of the Pacific (excluding adjacent seas) is 14,040 feet (4,280 metres), and its greatest known depth is 36,201 feet (11,034 metres)âin the Mariana Trenchâalso the greatest depth found in any ocean.
