Layers and deflections

Daily operation of the ST90 system may be disturbed by environmental situations that you
are unable to control. Typical conditions are temperature and salinity layers, as well as
deflections caused by increasing or decreasing water temperature.

Topics

Temperature and salinity layers, page 630

Sonar beam deflections, page 631

Temperature and salinity layers

You may experience that temperature and/or salinity layers exist in the water column. Since
the speed of sound in water depends on its temperature and salinity, such layers will cause
the sound beam to be reflected.

If you transmit a sonar beam down towards a temperature or salinity layer (A), it may be
reflected as indicated in the illustration. The school of fish (B) you thought you would see
will not be visible at all.
