Configuring the environmental parameters
Environmental parameters such as salinity, and sound speed play an important part to present
accurate echo data. Use the
Environment
parameters to define these values. Depending on
the current sea and weather conditions, you may need to change these values frequently.
Context
In order to obtain accurate echoes, it is very important that the sound speed through the
water is set correctly. Several parameters are required to calculate the correct sound speed
value. If these parameters are not known to you, use the default value 1494 m/s. This is a
typical mean value for sound speed.
Procedure
1 Open the
Setup
menu.
2 Select
Environment
.
Observe that the
Environment
dialog box opens.
3 Specify if you work in fresh or salt water.
4 Specify the sound speed.
5 Select
OK
to save the selected settings and close the dialog box.
