Fibre-optics help create most detailed picture of Greenland Ice Sheet
Scientists have used a fibre-optic sensor passed deep into a borehole to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet.
Their findings will be used to make more accurate models of the future movement of the world’s second-largest ice sheet, as the effects of climate change continue to accelerate.
The research team, including Dr Adam Booth from Leeds, used a new technique in which laser pulses are transmitted in a fibre-optic cable to obtain highly detailed measurements of ice properties from the surface of the ice sheet all the way to its base, more than 1,000 metres below.

A £2.5m highways improvement scheme to transform a gateway into Whitehaven has been completed, following the switch-on of traffic lights at the Bransty Row junction.
Cumbria County Council has delivered the project, designed to ease congestion and improve road safety with a clearer road layout for drivers, cyclists and pedestrians.
