Abstract:

In this paper the experimental procedure and some preliminary observations from a new series of experiments on the mechanism of oil spreading under fragmented ice are presented. Laboratory observations indicate that oil spilled under a granular ice cover initially spreads under the ice, with simultaneous migration through the porous cover. When the oil reaches the top of the ice cover, it starts to spread rapidly on the surface outpacing the spreading underneath. The rate of oil surfacing would depend on permeability, porosity, and thickness of the ice cover. In some cases the oil would not surface at all.
