Abstract

The AA. present here the velocity measurements derived from their campaigns 2007–2010 and compare the geodetic measurements against InSAR velocity fields from satellite platforms from 1995/96 and 2008. They find the spatial distribution of ice speeds from the InSAR is in good agreement within the uncertainty limits with their geodetic measurements. The AA. observe no clear indication of seasonal ice speed differences, but they find a speed-up of the outlet glacier Franklinbreen between the InSAR campaigns, and speculate the outlet is having a surge phase
