If Mount Everest were dropped into the Mariana Trench, its peak would still be more than a mile 1. The Mariana Trench is part of a global network of deep troughs that cut across the ocean floor.
They form when two tectonic plates collide. The depths of the Mariana Trench were first plumbed in by the British ship H. Challenger as part of the first global oceanographic cruise. The Challenger scientists recorded a depth of 4, fathoms about five miles, or eight kilometers using a weighted sounding rope.
In , the British vessel H. Challenger II returned to the spot with an echo-sounder and measured a depth of nearly 7 miles 11 kilometers. The majority of the Mariana Trench is now a U. Bush in Permits for research in the monument, including in the Sirena Deep, have been secured from the U.
Fish and Wildlife Service. Permits for research in the Challenger Deep have been secured from the Federated States of Micronesia. Students read about the establishment of the Mariana Trench Marine National Monument and discuss why it is important to preserve the Mariana Trench and surrounding area. Ocean trenches are long, narrow depressions on the seafloor. These chasms are the deepest parts of the ocean—and some of the deepest natural spots on Earth.

According to National Geographic, if you were to put Mount Everest at the bottom of the Mariana Trench, its peak would still sit around 7, feet below sea level. Toward the southern end of the Mariana Trench lies the Challenger Deep.
The first expedition happened in when Jacques Piccard and Navy Lt. Don Walsh reached the Challenger Deep in a U. Navy submersible. They were only able to spend 20 minutes there due to the extreme pressures, and their arrival stirred up too much dust from the seafloor for them to take any pictures.
Cameron was able to spend three hours there. And, of course, he captured video and took many photos—he is a Hollywood filmmaker, after all. The extreme pressures took a toll on his equipment, though. Already a subscriber?
