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 does the information gathered by ships using Sea Beam sonar differ from that collected with standard methods that use one sonar device?
A sonar uses one device and a sea beam uses a dozen sonar devices.
Does a ship have a sonar?
Most modern combat Navy surface vessels have Anti-Submarine Warfare (ASW) sonar arrays of some type, and at least 1 Aircraft Carrier does as well (newer carriers use their escort vessels for ASW sonar screens). Essentially, that comes down to Cruisers, Destroyers, and Frigates, which make up the bulk of a Carrier Battle Group or Task Force screen to protect the Carrier from submarine threats. However, those ships, as well as Carriers, also use fixed and rotary wing aircraft with deployable (dipping) and expendable (sonobuoys) sonar as well. Ship sonar systems include the main forward sonar arrays, as well as deployable Variable Depth Sonar (VDS) towed sonar systems.
What are the differences between side scan sonar multi-beam sonar?
Side scan sonar uses sonar to map the the ground below by emitting continuous sonar pulses while moving. The sound continuously reflects back to the system's receiver, which creates an image based on the energy of the signal received, where darker points in the image match things protruding from the ground and lighter spots indicate where there is nothing. It does not measure the depth. Side scan sonar is usually towed behind the vessel using it. Multibeam sonar is similar to side scan sonar, except that it is attached to the vessel (rather than being towed) and measures the time difference between sound emission and reception, rather than the energy of the incoming sound waves. Thus, it measures depth instead of making a picture.
How do scientists make maps of the ocean floor?
Sonar
Does sonar uses sound waves to measure water depth?
Yes. Active sonar generates a pulse, the echo is heard some time later. The time it takes for sound to travel from the generator to the reflector and back to the sensor discloses the distance from the sonar equipment to the object reflecting the sound waves. Passive sonar just listens and does not generate any sound pulses itself but through various analysis algorithms certain information about the distance to an object that does make sound can be obtained. Passive sonar is not used for finding the depth of water but for listening to ships.
