1 Opening the ADCP (acoustic Doppler current profiler) information pane
The ADCP (acoustic Doppler current profiler) information pane displays the velocities of the water currents in the horizontal and
vertical directions. Horizontal water velocities are shown in a 360-degrees presentation resembling a compass rose. Select the ADCP Views button on the top bar to open the ADCP information pane.
Prerequisites
This information pane is available only when ADCP functionality is activated.
Context
The ADCP (acoustic Doppler current profiler) information pane displays the velocities of the water currents in the horizontal and
vertical directions. The horizontal velocity is shown on the left side of the information pane. The vertical velocity is shown on the right side of the information pane. The numerical values are shown at the bottom of the information pane.
The vertical velocity presentation is optional. The presentation can be enabled or disabled on the ADCP page. The ADCP page is located in the Information Pane Options dialog box.
Each measurement of the water current velocity is presented as a vector drawn as an arrow. The length of the arrow indicates the velocity of the water. The tip of the arrow indicates the direction. The properties of the arrows are defined on the ADCP page in the Information Pane Options dialog box.
Horizontal water velocities are shown in a 360-degrees presentation resembling a compass rose. Your vessel is located in the centre of the presentation. Speed ranges are shown with dotted circles. Two different velocities are presented.
Water velocity
The measurement presents the estimated velocity of the water current within the active layer. The measurement is shown as a coloured arrow. The length of the arrow indicates the velocity of the water. The tip of the arrow indicates the direction.
If you have not selected a layer, the measurement is based on the entire depth of the water column.
The numerical values are shown at the bottom of the information pane.
Speed over ground/Course over ground
The ADCP information pane also presents the vessel's speed and course relative to the ground. The measurement is shown as a grey arrow. The length of the arrow indicates the speed. The tip of the arrow indicates the course.
The numerical values are shown at the bottom of the information pane.
Note
Horizontal velocity can be estimated relative to the vessel (Vessel Relative) or relative to the sea bottom (Geographical). Vessel relative velocities will have the vessel velocity superimposed on the current velocity. Velocities relative to the sea bottom is composed of the current velocity only.
The vertical velocity is presented with a bar graph. The upwards or downwards direction of the water current is shown. The length of the arrow indicates the velocity of the water. The properties of the arrow is defined on the ADCP page in the Information Pane Options dialog box.
Procedure
| 1 | Select the ADCP Views button on the top bar to open the ADCP information pane. |
| 2 | Click the bottom right corner of the information pane, and drag to requested size. |
| 3 | To close the information pane, select it one more time on the top bar. You can also select Close in the top right corner of the pane.

Further requirements
Use the ADCP page to control the basic properties of the ADCP information pane. To open the Information Pane Options dialog box, select the button on the Active menu. You can also select the Setup button in the information pane.
Velocity can be measured in different units. Choose the unit of measurement on the Units page. The Units page is located in the Installation dialog box.
