NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the sea floor such as shipwrecks, and map the sea floor itself. There are two types of sonarâactive and passive.
He used this technology to get sound wave readings of the ocean floor. This was a great discovery because it allowed scientists to get faster and more accurate readings. A device called an âecho sounderâ. is simply aimed downward, at which point it gives off a sound signal. The sound signal travels to the ocean floor and bounces, or. âechoesâ, off the surface. The device picks up the echo and then computes the ocean depth at that point. To do this calculation. yourself, all you need to know is the speed of sound in water (1,500 m/s), and the time it took for the sound signal to echo. During this activity, you will use this method to construct a map for two different regions of the ocean floor.
