Abstract
In this paper we compare the primary and secondary creep behaviour of polycrystalline solid ice and spray ice. All measurements were made with an OYO single cell pressuremeter. The polycrystalline ice was prepared and tested in the laboratory at -2°C. The spray ice was tested in situ at Mars Island, a man made island off the north coast of Alaska. Simple power law relationships are used to describe both the primary creep strain with time and the minimum creep rate as a function of stress. A considerable difference was found between the creep parameters for the two kinds of ice. The spray ice is much more prone to creep deformation than is solid ice at the same temperature.
