  1. C-axis fabric analysis of ice samples collected from the NEEM ice core

    Eichler, Jan; Weikusat, Ilka; Kipfstuhl, Sepp
    The focus of this Diploma thesis is the development of a new approach for the analysis of crystal orientations in polar ice, based on digital image processing. The c-axes orientations are measured on thin ice sections using automated polarized light microscopy. The measured data are stored in form of high-resolution digital images which have been evaluated only manually so far. The automatic detection of grains and grain boundaries and the extraction of their orientation and shape parameters enable a statistical acquisition of the ice microstructure. The analysis of c-axes distributions, grain sizes, misorientations between adjacent grains, grain boundary orientations etc....
