The one that says ‘Temperature’, -1.00 C is the battery temperature, note how you have selected ‘Temperature’ under the ‘Vehicle.battery’ section. This is not implemented.

The other three temperature readings are as I described in the above post.

The altitude is relative to the surface of the water.

I have [updated the descriptions](http://discuss.bluerobotics.com/t/qgc-v3-2-4-bluerobotics-rev2/1551) of these telemetry values to be more descriptive/clear.
