|Preferred Label||Sonar Equipment Services SES-5000 sub-bottom profiler series|
|Definition||A series of pinger sub-bottom profilers, designed to identify and characterise subsurface layers of sediment or rock in marine environments. The series includes the 5000, 5001 and 5001S, desinged to operate as combined transmitter and receiver systems. The transceiver generates single frequency tone bursts when triggered, which activates the transducer array (4x4). The transducers convert these to acoustic waves that travel vertically down through the water column to the sea floor. The acoustic waves may penetrate the seafloor for 10s of metres. At each material change interface some acoustic reflection may occur, which travels back through the water column to the transducers. The reflections are converted back into electrical signals for digital processing into an image, or section, for interpretation. The SES-5000 series operates at primarily 4.5 kHz with a pulse width of 2 cycles, but can operate between 3.5-9 kHz. The fastest trigger period os 75 ms.|
