What’s Actually at the Bottom of the Mariana Trench

If you’ve ever tried scuba-diving, you know that at some point during the descent, you’ll experience some unpleasant sensations. Your ears might pop, and you’re likely to feel some serious pressure. Luckily, it’s usually nothing serious if you do everything correctly. But what would happen to you at the bottom of the Mariana Trench?

So, if you want to get to the very deepest point of the ocean, you need to travel to the southern part of the Mariana Trench. There, you’ll find the Challenger Deep, a small valley at a dizzying depth of 36,037 ft! It’s so deep that if you put Mount Everest into the Challenger Deep, there would still be around 1.2 miles between the mountain’s peak and the surface.

– As you get deeper, you feel as if some invisible force is squeezing you from all sides, and the pressure is getting stronger.
– Usually, people can withstand 3 to 4 atmospheres of pressure without any particular problems. That means that you can submerge to a depth of 130-140 ft and still feel fine.
– During your descent, you notice that it’s getting darker. That’s because you’re leaving the sunlight zone of the ocean and going deeper – to the twilight zone, which starts at a depth of 660 ft.
– You reach the mark of 1,090 feet beneath the surface, and that’s the deepest a scuba diver has ever reached.
– The option will be to give up your diving idea and get inside a special submarine constructed for deep-dives!
– It’ll take you about two and a half hours to reach your destination.
– At a depth of 3,280 ft, your journey becomes quite boring and monotonous as you enter the midnight zone.
– Outside your submarine, the pressure is simply astonishing: it’s more than 1,000 times higher than the standard atmospheric pressure you experience at sea level!
– If your submarine wasn’t so sturdy, at the bottom of the Challenger Deep, it’d be instantly flattened to the thickness of an aluminum foil sheet.
– The temperature around your submarine is close to freezing – from 34 to 39 degrees F.
– The Challenger Deep is the home to more than 200 microorganisms that lead a comfortable life holed up in the cozy mud at the bottom.
– Even though the Challenger Deep is the deepest point of the ocean, it’s not the closest to the center of the Earth!
– The Mariana Trench is one of the oldest sea beds on Earth! Researchers claim that it may be up to 180 million years old!
– At the bottom of the trench, there are hydrothermal vents that emit super-acidic fluids.
– The bottom of the trench is covered with icky grayish-yellow sludge which is almost silky to the touch. It’s the remains of everything that ends up at the bottom after being crushed by the water pressure.
