Geophysics and Ice Mechanics

In order to estimate the consequences of global warming, an understanding of the deformation behavior of the large ice masses in the Antarctic and in Greenland are indispensable. By means of computational models based on viscous and viscoelastic material models for ice, simulations of the breaking off of large icebergs from shelf ice and swimming glacier lobes were made. Using remote sensing data, land measurings and lab measurings, the simulation models enable the prediction of fracture patterns in heave and calving events. Another central working point is the mathematical modeling of firn densification.
