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.

∙ 12y agoIn the 1800's, piano string and a lead weight were used to measure the depth of water in Crater Lake.
Merchant seamen have used the lead line for years. This was a lead weight on a line. The depth in fathoms was marked off with cloth and cords attached to the line at appropiate intervals. The lead weight had a hollow at the bottom, which when filled with wax tallow, would give an indication of what was on the seabed.

sonar - by bouncing sound signals off the bottom of the ocean, they were able to map the depth of the ocean. Deep sea diving would take too long. Satellites were not in orbit until the 1970's and submarines were not necessary since sonar could be done from the surface on a boat.
