Deep oceans present challenges for human exploration due to extreme pressures and lack of light. The document discusses methods used to explore depths beyond recreational SCUBA diving limits, including manned submersibles that can transport people to over 35,000 feet deep. Unmanned technologies like remotely operated vehicles and autonomous underwater vehicles are also used to study deep zones and collect data without risking human lives. Special equipment is necessary to allow deep ocean exploration by humans, who are not naturally adapted to such extreme environments.

2. Deepest Depths Explored By Humans Free/Scuba Diver– 417 ft. JIM Diving Suit – 1968 ft. Ben Franklin Sub – 2000-6000 ft. Bathysphere and Johnson Sea Link – 3000 ft. Challenger II – 35,838 ft. (7 mi. over head)

3. Exploration Methods Submersibles Built to transport humans to deep depths. ROV’s Remotely Operated Vehicles. Carry equipment, not humans, to make measurements under human control Baited Camera Stations AUV’s Autonomous underwater vehicles. Pre-programmed to move and collect data on their own.

4. Deep Ocean Zones Top - 650 ft. – Epipelagic 650 - 3300 ft. – Mesopelagic 3300 – 13000 ft.- Bathypelagic 13000 – sea floor – Abyssopelagic Sea floor and beyond – Hadopelagic

5. Special Equipment/Clothing Since humans are not meant to survive in deep oceans, the following equipment is required for deep ocean exploration: Scuba Gear Scuba Mask Scuba Fins Oxygen Tank
