Surface noise/aeration

When the waters are rough or the boat passes over a wake, surface noise may appear near the zero line. As surface turbulence is acous- tically equivalent to running into a brick wall, the bottom echo will be displayed intermit- tently. Similar noise sometimes appears when a water temperature difference (thermocline) exists. Different species of fish tend to prefer different temperature zone, so the thermocline may be useful to help identify target fish. 200 kHz tends to show shallow thermoclines bet- ter than 50 kHz.

In rough waters the display is occasionally in- terrupted due to below-the-ship air bubbles obstructing the sound path. This also occurs when the boat makes a quick turn or reverses movement. Lowering the picture advance speed may reduce the interruption. However, reconsideration of the transducer installation may be necessary if the interruption occurs frequently.
