Abstract: Floe rafting, or a process where a thin ice cover broken into small floes is compressed into multiple thickness, is considered. Based on ice tank experiments on the compression of small floe systems the main dynamical and morphological features of the process are described. After the initial phases of the compression force increases linearly wi th the thickness of the floe system. The force is dependent on fl oe thickness but not on floe diameter. In continuing compression the floes gradually turn into a more upright arrangement.
