calculated using the integration values in the Echogram and
Range view.
Position the cursor in the Single Echo view, click the right
mouse button to open the Echo Trace dialogue box.
Click the TS Detection button to open the TS Detection
Parameters
dialogue box.
The TS Detection Parameters dialogue box contains
parameters used by the ES60 program to detect single echoes.
These parameters are essential for determining which echoes are
accepted as single echoes. Thus, if fish abundance estimation is
based solely on single echo detection, this estimate may be
affected by the choice of single echo detection parameters.
If you choose to store raw acoustical data during a survey, you
can later change the single echo detection parameters using
Replay mode. This allows you to examine the sensitivity of the
fish abundance estimation to the value of the single echo
detection parameters.
Click OK to accept the default settings and to exit the TS
Detection Parameters dialogue box. Click OK once more to
exit the Echo Trace dialogue box.
Echogram and Range view
The Echogram and Range view consists of an Echogram field
to the left and a Range field to the right. These are separated by
the range axis. The Echogram field contains information about
the acoustical values, while the Range fieldisusedfor
specifying the range used in the Echogram field.
Echogram field
The Echogram field is used to display acoustical values for
each ping. The settings in the Colour Scale are used to
determine the colour sensitivity in the echogram.
Position the cursor in the Echogram field, and click the right
mouse button to open the Echogram dialogue box.
The Echogram dialogue box allows you to define the area of
interest for the echogram. Your choice will affect the meaning
and the options in the Range fieldintheEchogram view. You
can also choose the TVG function used to calculate the
acoustical values.
In this example, choose Surface – Manual to enable a surface
related echogram. Then, choose the School gain TVG function
for calculating s
V
-values. Finally, click OK to accept the
settings.
