See the file

QMIPSFMT.H for the placement of these variables.

5. Towfish depth (computed in step 1) is displayed in the Depth field in the Telemetry

area in the Parameter Display window.

6. The values received in step 1 and computed in step 2 are displayed in the CTD

Computed Data area of the Sensor Display window.

• Temperature (degrees C)

• Depth (meters) will be the same depth as in the Parameter Display window

unless the depth value in the Parameter Display has been overridden with

a manual depth setting.

• Sound Velocity (meters per second) is computed using Chen Millero formula.

• Conductivity (Siemens per meter)

• Turbidity (percent of daylight)

• In playback mode, the same data are displayed in the Sensor Display

window as in record mode.
