Humans have explored the deepest depths using various vehicles, with the Challenger II reaching over 7 miles deep. Exploration methods include submersibles to transport humans, remotely operated vehicles controlled from above to make measurements without risking human lives, baited camera stations, and autonomous underwater vehicles pre-programmed to collect data on their own. The deep oceans can be divided into zones from the epipelagic down to the hadopelagic at the sea floor and beyond.
