EXPEDITION OVERVIEW

The Five Deeps Expedition was the first to reach the deepest point in each of the Earth’s five oceans: the Puerto Rico Trench in the Atlantic South Sandwich Trench in the Southern Ocean Java Trench in the Indian Ocean Challenger Deep in the Pacific and Molloy Deep in the Arctic.

How deep can a human dive?

That means that most people can dive up to a maximum of 60 feet safely. For most swimmers a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.

Can humans get to the bottom of the ocean?

The deepest point ever reached by man is 35 858 feet below the surface of the ocean which happens to be as deep as water gets on earth. To go deeper you’ll have to travel to the bottom of the Challenger Deep a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.

Why is the ocean so deep?

The ocean has an average depth of approximately 3.7 kilometres (or 2.3 miles). … The extreme depth of the Mariana Trench and other oceanic trenches is caused by subduction – where on the boundary of two converging tectonic plates one descends down into Earth’s mantle creating a deep trough.

Can the ocean be deeper than thinking?

The likelihood of Mariana Trench being the deepest is unlikely as the crust of the Earth is 70 km deep and Challenger Deep. Some say that the Mariana Trench is deeper than we know.

What lives in the Mariana Trench?

The organisms discovered in the Mariana Trench include bacteria crustaceans sea cucumbers octopuses and fishes. In 2014 the deepest living fish at the depth of 8000 meters Mariana snailfish was discovered near Guam.

At what depth will water crush you?

Human beings can withstand 3 to 4 atmospheres of pressure or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot or one atmosphere per 33 feet of depth and presses in from all sides. The ocean’s pressure can indeed crush you.

Can you fart while diving?

Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.

How deep can a submarine go?

A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2 200 meters or about 1.3 miles. The average depth of the world’s oceans is 3 790 meters or 12 400 feet or 2 ¹⁄₃ miles.

How dark is the bottom of the ocean?

After the aphotic zone there’s complete darkness. From 1 000 meters below the surface all the way to the sea floor no sunlight penetrates the darkness and because photosynthesis can’t take place there are no plants either.

How much of the ocean is discovered?

According to the National Ocean Service it’s a shockingly small percentage. Just 5 percent of Earth’s oceans have been explored and charted – especially the ocean below the surface. The rest remains mostly undiscovered and unseen by humans.

How much of the earth is still unexplored?

The extent of human impact on these underwater ecosystems is impressive. Still we’ve only mapped 5 percent of the world’s seafloor in any detail. Excluding dry land that leaves about 65 percent of the Earth unexplored.

Does the ocean ever end?

But neither reveals how the water that covers most of our planet might one day disappear for good. Those who believe Earth’s oceans are on an evaporation course say they have about 4 billion years left. … By this point Earth’s temperatures will be in the thousands of degrees.

What is the scariest thing about the ocean?

Creatures like the fangtooth (!) goblin shark and frilled shark are far more terrifying than anything you’d discover on land. Scarier yet we’re always finding new monsters in the ocean: in fact the largest colossal squid ever discovered was found just 11 years ago.

Has anyone been to bottom of Mariana Trench?

On 23 January 1960 two explorers US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey Don Walsh tells the BBC about their remarkable deep-sea feat.

What is the deepest a person has ever been in the ocean?

Vescovo’s trip to the Challenger Deep at the southern end of the Pacific Ocean’s Mariana Trench back in May was said to be the deepest manned sea dive ever recorded at 10 927 meters (35 853 feet).

What is the deepest a human has been in the earth?

Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface the Kola Superdeep Borehole SG-3 retains the world record at 12 262 metres (40 230 ft) in 1989 and still is the deepest artificial point on Earth.

Are there monsters in the Mariana Trench?

Despite its immense distance from everywhere else life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores amphipods and holothurians (not the names of alien species I promise) all call the trench home.

Is Megalodon in the Mariana Trench?

How deep can a human dive before lungs collapse?

Since theoretically the human lung will only collapse completely at depths >200 m [5] gas exchange through the alveolar capillary interface will not cease up to that depth and thus nitrogen will diffuse along the alveolar–tissue pressure gradient to become dissolved in tissues during descent.

How many ATM Can a human survive?

A person can withstand perhaps 100 atmospheres of pressure if they aren’t breathing air – divers do it. If they are breathing air the limit is just a handful of atmospheres.

What happens if you fart in space?

Surprisingly that isn’t the biggest problem associated with farting in space. Though you’re definitely more likely to worsen a small fire when you fart it won’t always injure or kill you.

What happens when you fart in a wetsuit?

As we ascend the wetsuit neoprene or drysuit gas expands as does the BCD air so we gain buoyancy. … Similarly when you fart while scuba diving in a wetsuit gas is lost from your body so you will technically become less buoyant. The impact is however minimal due to the fart’s small volume.

Do submarines hit whales?

Are there plants in the deep ocean?

Deep in the ocean the pressure is high and the temperatures are low. However plants and animals can still thrive in those places that were once seen as impossible for sustaining life. Far fewer varieties of plants live in the deep ocean compared to shallower waters that receive more sunlight.

Why is the deep ocean cold?

Cold salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface. … Water gets colder with depth because cold salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.
