In the cryosphere of Earth and other planets, nonlinearity lies at the heart of almost every major observation of interest. In glaciology there has been a strong tradition of combining observational and model-based approaches to understand how complex and organised behaviour emerges from the coupling of processes. Previous studies have encompassed pattern formation, oscillatory dynamics, and scale dependence in describing and explaining observed phenomena in glacial geomorphology, glacier and ice sheet dynamics and elsewhere. Many more types of nonlinear complexities await exploration. We invite contributions on all aspects of nonlinearity in the cryosphere, including pattern formation on terrestrial and Martian ice caps, surges in glaciers and ice stream dynamics, glacial earthquakes and other basal phenomena, as well as nonlinear processes and pattern formation in frost heave, sea ice dynamics and seasonal snow cover.

We welcome abstracts focusing on observational and theoretical work across the whole spectrum of cryospheric research, and aim to encourage exchanges between cryospheric scientists, physicists and applied mathematicians.
