How deep could people dive

Who dives how deep?

40 meters is the limit for recreational divers. Diving with normal compressed air without further safety precautions is only considered safe up to this limit.

214 meters The Austrian apnea diver Herbert Nitsch managed it in 2007 - with a single breath, without an additional air supply. Medical professionals are still puzzling over how people survive such depths.

332.35 meters is the world record for scuba divers. It was set up in 2014 by Ahmed Gamal Gabr. At this depth a special gas mixture has to be breathed, because normal air would be fatal there.

Up to 450 meters People can dive deep in pressure suits that look like metal armor. They are lowered from the surface of the water with cables and then pulled up again.

500 meters the emperor penguin dives deep. Penguins prefer to hunt where it is dark. The lighter it is, the deeper they dive; in the dark they hunt closer to the surface of the water.

700 meters seals dive deep. They are crepuscular and nocturnal animals. Their diving ability is impressive: When hunting, they dive around 30 times to depths of up to 700 meters. After 20 minutes at the latest, they need new oxygen and appear.

In 1000 meters The Atlantic anglerfish lives deep (Lophius piscatorius). It is a so-called frogfish that can be up to 1.70 meters long. Due to its huge mouth and very elastic stomach, it can even devour fish as big as itself.

1370 meters Deep-sea pioneers Otis Barton and William Beebe reached depth in 1948 with their "bathysphere", a steel ball hanging from a cable. As early as 1934 they had set a groundbreaking diving record of 923 meters with the ball.

1500 meters deep dive sea turtles. Not only are they excellent divers, they swim very far and cover distances of thousands of kilometers.

2070 meters: The summit of Mount Everest would only rise up to this point if it were placed in the deepest point of the Mariana Trench.

2800 meters: The artist Emory Kristof photographed squids at this depth. But they probably live much deeper in the sea.

3000 meters: The sperm whales hold the diving record among mammals. In order to save oxygen, you can switch off all organs that you do not need during the dive.

3800 meters: At this depth lies the wreck of the Titanic in the North Atlantic, 368 miles southeast of Newfoundland.

4500 meters: That is how deep the American research submersible "Alvin" comes. With the "Alvin", scientists discovered the "black smokers" in 1977 at a depth of more than 2000 meters off the Galapagos Islands.

6000 meters: The diving robot "Victor 6000" can dive into this depth and work there for several days. "Victor 6000" helps with the exploration of the seabed of the Arctic. The Russian submarines "MIR I" and "MIR II" are even suitable for manned diving trips at this depth.

8000 meters:Brotula galatheae is called the "deepest fish" that has ever been caught. If you wanted to pull it to the surface from this depth, it would burst, because normally it lives under a pressure that is 800 times as great as on land.

10,928 meters: The greatest depth humans have ever plunged into. For a long time Jacques Piccard and Don Walsh held the record with the "Trieste" submersible. On January 23, 1960, they managed to dive 10,912 meters deep. It was not until 2019 that the record was broken by US adventurer Victor Vescovo, who dived 16 meters deeper with the special submersible "DSV Limiting Factor".

11,034 meters: The deepest point of the world's oceans, the "Vitjas-Tief 1" in the Mariana Trench. Only the unmanned Japanese underwater robot "Kaiko" was ever there. There are now doubts as to whether the Vityas low is actually the deepest point. The measurement of the Soviet research vessel Vityas took place as early as 1957.
