Why is the ocean still unexplored?
Today, over 80% of the global ocean (and 50% of the U.S. Ocean) is still unmapped, with even more unexplored. One of the biggest challenges of ocean exploration is the intense pressures in the deep ocean. In addition, zero visibility and extreme cold temperatures make it difficult to explore the vast ocean.5%

In fact, most of the waters remain unexplored, uncharted and unseen by our eyes. It might be shocking to find out, but only 5% of the ocean has been explored and charted by humans. The rest, especially its depths, are still unknown.More than 80 percent of the ocean has never been mapped, explored, or even seen by humans. A far greater percentage of the surfaces of the moon and the planet Mars has been mapped and studied than of our own ocean floor. Although there is much more to learn, oceanographers have already made some amazing discoveries.

What don’t we know about the ocean : Only 20 percent of the ocean floor has been mapped. What's down there Currently, only 20 percent of the seafloor has been mapped, making it a more mysterious place than the surface of the moon or Mars.

Why is 95% of the ocean unexplored

Conditions in the deep-sea environment include very high pressures, total darkness, extreme temperatures, and toxic chemicals.

What lives at 13,000 feet underwater : Dumbo Octopus

This adorable little octopus is perhaps the deepest of our eight deep-sea creatures: they only live deeper than 3962 meters (13000 feet). Many have been observed by ROVs during exploratory dives, and as they have quite a cute appearance, they have gained a lot of fans around the world.

But we don't… We have only explored five percent of our world ocean. That means that 95 percent of our ocean is unknown. Help protect our ocean by sharing what you've learned.

Will the ocean ever be explored

But the ocean will never be fully explored. Earth is constantly changing, and it's important to understand these changes given the importance of the ocean in our everyday lives. While there's a lot of work to be done, there's also so much more to discover!Most recreational divers rarely dive deeper than 130 feet. But commercial divers can use atmospheric suits to descend to depths up to 2,000 feet. Some recreational divers have descended to depths of 1,000 feet and beyond and survived the experience without any problems.While there's no precise depth at which a human would be 'crushed', diving beyond certain limits (around 60 meters) without proper equipment and gas mixes can lead to serious health issues due to the pressure effects on the body, including nitrogen narcosis and oxygen toxicity.

A mere 5 percent of the global ocean has been explored, and less than 10 percent mapped using modern sonar technology. If we can send satellites millions of miles into space, then why has so much of the ocean's wild frontier been left unmapped, unobserved and unexplored Well, it's complicated.

What is killing the ocean the most : A big part of the problem: pollution. So how does trash get into the ocean It's dumped, pumped, spilled, leaked and even washed out with our laundry. Each year, we expose the world's waterways to an increasing variety of pollutants — plastic debris, chemical runoff, crude oil and more.

Can a human dive 2,000 feet : In 2006 Chief Navy Diver Daniel Jackson set a record of 610 metres (2,000 ft) in an ADS. On 20 November 1992 COMEX's "Hydra 10" experiment simulated a dive in an onshore hyperbaric chamber with hydreliox.

What depth of water will crush a human

While there's no precise depth at which a human would be 'crushed', diving beyond certain limits (around 60 meters) without proper equipment and gas mixes can lead to serious health issues due to the pressure effects on the body, including nitrogen narcosis and oxygen toxicity.

And decompression techniques while the future of deep sea diving looks bright none of this will help Mark in the here. And now.The pressure at 13,000 feet underwater is about 1,000 atmospheres, about 100 times the pressure at sea level. This pressure would have a devastating effect on the human body. The lungs would collapse, and the blood vessels would burst, leading to internal bleeding.

What will the ocean look like in 2050 : Rivers of pollution flow into the ocean every day, with little sign of slowing down. Marine animals and birds now regularly eat plastic, and so do humans. It is estimated that by 2050 there could be more plastic in the sea than fish. As the plastic piles up, fish disappear.
