Deep sea trenches are among the most remote places on the surface of the Earth. They can be a couple miles deeper (6 miles) than the average depth of the ocean floor (4 miles). They are almost inaccessible by human beings because the pressures along the ocean bottom are so extreme.
The Alvin, shown being recovered by divers in this picture, was the first deep-sea submersible. It was designed by scientists to explore the ocean floor, including the deep sea trenches, and can dive deeper than most submarines. The deepest dive recorded by the Alvin is 6,600 meters, which is almost 4 miles down.
Research vessels like the Alvin allow humans to find such creatures as methanogens which live near hydrothermal vents along the ocean floor. The next image shows a view of the Alvin underwater.
