Tamara Gerber: Ice in the Northeast Greenland Ice Stream is 50x harder in the centre of flow, resisting along-flow extension/compression. While the shear margins are relatively soft. #EASTGRIP #NEGIS

Crystal orientation fabric anisotropy causes directional hardening of the Northeast Greenland Ice Stream - Nature Communications

This study uses radio-echo sounding measurements, ice-core data and models to map the spatial variation in ice-crystal orientation in the northeast Greenland Ice Stream and shows how it potentially affects the ice-flow dynamics in this region.

Accelerating ice flow at the onset of the Northeast Greenland Ice Stream

Deep in the interior of the Greenland ice sheet, ice flow is speeding up — but not due to recent changes in climate.

#EGRIP #EastGRIP drilled through the North-East Greenland Ice Stream #NEGIS yesterday. Great moment!

Here's a screen recording of some data from the drilling of the #EastGRIP ice core from a moment ago.
A 3.36m long ice core was retrieved from 2520m depth. The winch had to pull with ~1600 kg to break the core free from the bottom.
