Fun Fact: The Mariana Trench

The world-famous Mariana Trench is a wonder humans have yet to fully understand. As it currently stands, the Mariana Trench holds the record for the deepest ocean depth at 36,201 feet (or 11,034 meters).

Venturing down below water this deep puts an immense amount of pressure on a vessel or a human body so high that we cannot explore beyond a certain point, so how was this depth measured? Much like dolphins using echolocation, oceanographers used sound waves. Sound waves were projected from the surface and bounced off the ocean bottom, the time it took to bounce back was recorded, and the distance to the bottom was recorded.

Strange and even frightening creatures dwell in the trench, such as the Angler fish.
