INCREASED MELTING OF MAJOR ICE CAP

Observations by the new European Union's Sentinel-1a radar spacecraft reveal a marked increase in the flow speed of an ice cap glacier in Norway.

This is the glacier at Cap Mohn on the Austfonna ice cap. Scientists had suspected this ice cap was losing substantially more ice through its main drainage glacier.

The Sentinel-1a results confirm this view. Sentinel-1a was launched only last month.

Professor Andy Shepherd from Leeds University said 'We've observed  Austfonna with various satellite radar datasets over the past 20 years, and it hasn't done very much. But we've now looked at it again with the new Sentinel-1 spacecraft, and it's clear it has speeded up quite considerably in the last two or three years.. It is now flowing at least 10 times faster than previously measured.'

Comment: These early findings from Sentinel-1a provide further scientific evidence of an increased rate of glacier melting in Norway.
