The Greenland ice sheet is melting at an increasing rate, a process accelerated by glacier calving. For the first time, this has been measured by an international research team using fibre-optic cables and Distributed Acoustic Sensing (DAS) technology. www.swissinfo.ch/eng/glaciers...

Fibre optics detect the invisible waves that melt Greenland’s ice sheet

The breaking off of large chunks of ice from glaciers accelerates the melting of the Arctic ice sheet in Greenland.
