Continuous measurement based on a reliable and simple method

The device is installed on the surface of the glacier and a rope is uncoiled into a hole drilled in the ice. As the ice melt, the elevation of the device decreases and the rope coils back. The instrument measures the winding of the rope and computes the corresponding vertical displacement, hence the cumulative ice ablation.
