Did you know that in the year 1930, a man invented the bathysphere? I learned from my Social Studies that a man designed the bathysphere so that it could be lowered from a ship by connecting cable onto the ocean floor more than a half a mile, almost one kilometer, from the surface. Cables are strong ropes made of metal. Divers could stay under water in the bathysphere for several hours. However, in a bathysphere, it was not possible to follow around the interesting animals of the sea. Once the bathysphere was lowered by the cable, it had to remain there until the cable was pulled up again.
This is a picture of a bathysphere.
Later, a more complex vessel was invented. It is called a bathyscaphe. In bathyscaphe, scientist can remain under water for several days in order to study the conditions of the ocean floor and the kinds of animal life which live there.
BathyscapheA bathyscaphe was used to plunge into the greatest ocean depth known to man.
This is an interesting fact I learned this week. Want to learn more? Visit Bee Wise.
