Oceans cover 70 percent of the Earth's surface, yet even today their depths remain largely unexplored. For example, the Monterey Accelerated Research System (MARS) rests on the floor of the Pacific Ocean at 980 meters to monitor seismic faults. Like space exploration, deep sea exploration requires new instruments and technology. Jacques Cousteau and Emile Gagnan developed the Aqualung, which was the first true "Scuba" (Self Contained Underwater Breathing Apparatus) system. Special tools have been developed to explore this cold, dark, pressurized environment. Remotely operated vehicles (ROVs) are tethered vehicles that are controlled by researchers on a ship. These sensors may be attached to profiling buoys, which drift freely at a depth of about 1000 meters. Filmmaker and National Geographic Explorer James Cameron on March 25, 2012, became the first human to complete a solo submarine dive to Challenger Deep, an undersea valley in the Mariana Trench of the Pacific Ocean known as the deepest surveyed spot on the planet. We now know that despite this lack of light, many creatures can live in this extreme place, such as: microorganisms in hydrothermal vents, deep sea corals, fish, and many other bizarre creatures.

Every year, the ocean contributes $1.5 trillion to the global economy. What really irks Jamieson – who spent most of 2018 and 2019 as chief scientist on board the research vessel of American deep sea explorer Victor Vescovo – is that we do actually know quite a bit about the ocean floor, and we are constantly learning more. We’ll look at the history of ocean exploration, and we’ll look at how the ocean controls the planet itself. The history of deep sea exploration begins relatively recently, mainly because advanced technology is needed to explore the depths. Exploring the Deep There is only one way to explore the very bottom of the sea – in an underwater craft called a submersible. Their adventures tap into the explorer in all of us as they investigate the mysterious depths of the ocean – that final unexplored frontier on our own planet. The Integrated Ocean Drilling Program (IODP) Chikyu analyzes sediments from the Earth's crust and may become the first ship to drill into the Earth's mantle. To fishermen, the deep sea is any part of the ocean beyond the relatively shallow continental shelf. Three people have visited the depths of the Challenger Deep. The very deepest depth of the ocean is roughly 2,000 meters deeper than Mount Everest is tall—36,070 feet deep (10,994 m)! Given the high degree of difficulty and cost in exploring our ocean using underwater vehicles, researchers have long relied on technologies such as sonar to generate maps of the seafloor.
