Science ABC —
During World War II, scientists around the world were experimenting with new technology to help them win the war. Among such crucial inventions and innovations, such as the computer and the first atomic bomb, was SONAR.
SONAR had previously been used during World War I, and was especially useful for anti-submarine warfare.
However, scientists working on improving the technology spotted something strange during their tests; the ocean floor was much shallower than expected, only a few hundred meters from the surface. Even stranger was that the ocean floor appeared to come up to the surface at night. What was going on here? And what did it reveal about what happens at the bottom of the ocean?
First, we have to learn how SONAR works.
