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.
The researchers were able to levitate and transport items ranging from a droplet of water to a toothpick. They did so using pairs of sound-emitting platforms and reflector sheets. Sound leaves the sound-emitting platform, hits the reflector, and bounces back in the direction it came from.
