Side Scan Sonar is a category of sonar systems used to create an image of the ocean floor. This
image can be of very high quality, and can discern objects within the scan area with clarity,
regardless of the murkiness of the water. The scan is done by a “tow fish”, or using a side
mounted transducer, which is positioned in the water off the side of the survey vessel. The
tow fish sends and receives soundwaves, which are then processed by a computer.
