Post-Doctoral Fellowship - Understanding the compaction of snow firn

The successful applicant will determine the mechanisms of firn compaction as a function of depth for a firn core obtained from Summit, Greenland in June 2017. The work will utilize a combination of dynamic in-situ compression testing in an X-ray computed microtomograph, and detailed microstructural examination in a cold-stage-equipped scanning electron microscope with electron backscattered diffraction and energy dispersive X-ray spectroscopy, and microRaman spectroscopy. The aim is to understand the effects of both temperature gradient and overburden pressure on firn compaction, and model the results. 

Previous experience with X-ray microtomography, deformation modeling and/or working with snow or ice would be useful.
