I am a graduate student at NTNU (Norwegian University of Science and Technology) in Norway. I belong to the geographical department and taking a specialization in geomatics. In my thesis I do a development of a 3D visualization tool for integrated analysis of surface and subsurface data - Applied to the case of perennial ice patches. In my work, I combine surface data from DGPS surveys and terrestrial laser scanning with a dense network of ground penetrating radar profiles two reveal data on mass balance, ice structure and ice patch thickness
