NOAA Photo Library Image - ship4377

Figure 7. Autonomous ultrasonic tide recorder. This instrument was mounted on the bottom and emitted sound waves that reflected off the water surface. As the water level changed, the instrument would record the apparent changes in depth. This instrument was developed for Crouzet Marine Oceanology Corporation from a prototype developed by the Studies and Research Department of France Electric.
