Channel ID
|
Channel ID fields from the data file. This information enables you to match the derived single beam variable to a beam in the derived multibeam variable. |
| Sound speed | Logged sound speed (m/s) |
| Transducer draft | Logged transducer draft (m) |
| Sample interval | Single beam sample interval (s) |
| Transmit power | Single beam transmit power (W) |
| Pulse length | Single beam pulse length (ms) |
| Transducer gain | Single beam transducer gain (dB) This is not displayed for Angle data, see Transducer gain. |
| Absorption coefficient | Logged absorption coefficient (dB/m) This is not displayed for Angle data. |
| Sa correction | Single beam Sa correction (dB) Displayed for Sv data only. |
|
Minor-axis steered angle
|
The ME70 Alongship beam steering angle (degrees) of the beam for the derived single beam variable. Note: Exported EVD data for single beam variables may include steered angles from the first ping. |
|
Major-axis steered angle
|
The ME70 Athwartship beam steering angle (degrees) of the beam for the derived single beam variable. Note: Exported EVD data for single beam variables may include steered angles from the first ping. |
