What does a bathyscaphe do?

A bathyscaphe is a self-propelled vehicle used for deep-sea dives. Bathyscaphes can dive deeper than a person with scuba gear, and even deeper than submarines. Design features reveal that the bathyscaphe was engineered with one goal in mind: to reach the deepest depths of the ocean.

How deep can a bathyscaphe dive?

about 10,911 metres
Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe which reached a record depth of about 10,911 metres (35,797 ft) in the Challenger Deep of the Mariana Trench near Guam in the Pacific.

What does the word bathyscaphe mean?

: a navigable submersible for deep-sea exploration having a spherical watertight cabin attached to its underside.

How is Cameron’s sub different from the Trieste?

James Cameron’s DEEPSEA CHALLENGER submersible deploys technologies unimagined in the 1960s. Whereas the Trieste took nearly five hours to descend and more than three hours to ascend, the DEEPSEA CHALLENGER reached the bottom in about two and a half hours and returned to the surface in 70 minutes.

What are the drawbacks of a bathyscaphe?

As the water is removed, the density of the submarine decreases, and the submarine surfaces. The problem with this approach for an underwater vehicle is that the ballast tanks must be built sturdy enough to ensure that the pressure outside the tanks cannot crush them. This means big, heavy, and expensive tanks.

What do they fill a bathyscaphe with?

gasoline
The bathyscaphe consists of two main components: a steel cabin, heavier than water and resistant to sea pressure, to accommodate the observers; and a light container called a float, filled with gasoline, which, being lighter than water, provides the necessary lifting power.

How deep can modern submarines go?

As a result, the submarines are capable of diving to depths of up to two thousand feet, and crush depth estimates run from 2,400 to 3,000 feet.

What is the difference between bathyscaphe and submarine?

is that submarine is a boat that can go underwater while bathyscaphe is a self-propelled deep-sea diving submersible for exploring the ocean depths, consisting of a crew cabin similar to a bathysphere suspended below a float filled with a buoyant liquid such as petrol.

Which submarine is deepest?

This is about as low as any person can go. The Chinese submersible Fendouzhe just reached one of the deepest spots on the planet, reaching a dizzying (and dark) depth of 35,791 feet (10,909 meters), according to a state-run news agency.

What makes Alvin the submarine so special?

In the past half century, the deep-sea submersible has made more than 4,700 dives all over the world. It has discovered hydrothermal vents, explored the Titanic, and searched for a missing hydrogen bomb in the Mediterranean Sea. It even spent a year—while lost—at the bottom of the ocean.

Are Bathyspheres still used?

Although the technology of the Bathysphere was eventually rendered obsolete by more advanced diving vessels, Beebe and Barton’s Bathysphere represented the first time that researchers attempted to observe deep-sea animals in their native environment, setting a precedent which many others would follow.
