'[OT] MEASURE ICE THICKNESS FROM TOP'

I have a friend who is a die hard ice fisherman.  He was wondering if there is a way to measure the thickness of ice on a lake with out drilling a hole in it.

Anyone know of some type of sensor that would do this?

Ultrasound. Commercial thickness gauges for steel cover a few inches.
Don't know about ice.
Some experts can tell from sledge hammer thump on top.

After much reading I think a robot with a drill attachment.
as you apply down pressure the robot front lifts. Start the drill. When the robot drops the drill is through the ice.  Take a measurement and move on.

With a small GPS unit and a radio link you could map out a body of water or ice.

Something to think about for when I have too much time on my hands.

Or you could try an ultrasonic Doppler sensor (car back-up device). The interface ice water will cause a reflection, so you can deduct ice thickness.
 
Good luck,
