That was a really cool talk Janosch! Apologies for not being able to ask you after the talk, but I was wondering if your results are driven by the same processes as has been seen for glaciers in the Yukon: doi.org/10.1002/jgrf...
It would be very interesting to see if this is a global phenomena.

Comparison of thermal structure and evolution between neighboring subarctic glaciers
Polythermal structure mapped in two neighboring glaciers We simulate observed meltwater-dominated thermal structure Differences in the observed thermal structure related to glacier dynamics
