Deep trenches are most likely to be found in the western Pacific Ocean, generally the arc between Tonga and the Philippines.
The deepest submarine is built to go 10000 meters under water. This is so they can go to the bottom of the ocean floor.

surface/ open ocean zone was warmer than the deep ocean. Sunlight can reach the open ocean so the temp. is warm.
Sylvia Earle was born in 1935. She designed a small submarine for underwater exploration. She started a business called Deep Ocean Engineering which builds the small submarines, which can reach 35,000 feet, the deepest ocean depth known.
