A Chirp system emits an acoustic pulse (called a “ping”) from the transducer that travels down through the water column. When the ping hits the sediment some of that acoustic energy is reflected back towards the tow-fish.  A Sub-bottom profiler is a type of sonar system that produces a 2-dimensional stratigraphic cross section by using acoustic energy to image sub-surface features in an aquatic environment.
