Who invented sonar?
It was Lewis Nixon who invented the very first sonar-type listening device in 1906. He was seeking a way of detecting icebergs. But the sonar was not "invented", its inventor was nobody, but developed through the years. Sonar had very humble beginnings, from crude instruments to advanced technology. (However, the natural sensory process cannot be invented, see bisonar or echolocation for that.) The first attempts to interpret sound waves created by vessels was by Leonardo Da Vinci in 1490, when he used a tube that detected vessel movements when placed in water.

How was sonar invented?
Sonar was never 'invented' as such, it was adapted from nature. Bats, many deep water fish and small bugs rely on sonar. Bats for example are almost all blind and guage their position relative to their prey based on how long it takes for their high pitched calls to bounce off surrounding objects and get back to them.

What do scientists use to map the ocean floor?
sonar they use a sonar LIDAR or Sonar a sonar SONAR sends out ultrasonic sounds to the bottom of the sea and analyses how they bounce back sonar Sonar. with sonar by using soundwaves that create a image based off of the height of the object Bathymetric sonar and LIDAR (Light Detection And Ranging).

Who invented the echo-sounding devices for mapping the ocean floor?
H E Edgerton, improved greatly on the stroboscope and this was made widely available by General Electric. Strobes had been invented more than a hundred years earlier in Belgium. He then went on to improve sonar, by introducing the element of 'side-scan' sonar, with which many pictures of the ocean floor are made. These have much more resolution and display than 'ping' sonar.
Asked in Science
What was used before sonar was invented?
Before sonar, there were applications where individuals actually "listened to the water" with different devices. It was largely impractical for any kind of "real science" or "real military" applications, and probably was viewed as a novelty. But the first submarines were equipped with a crude (by modern standards) sonar, so the technology developed with the military need for it.
