This project is a laboratory study of the incorporation of ocean bottom         sediment into a sea ice cover.  Such a phenomenon is widely observed in         the shallow waters of the Beaufort sea off the northern coast of Alaska         where the sea ice may contain large concentrations of fine-grained              sediment.  The included sediment has a significant effect on the                transmission of light through the ice and thus affects marine biological        processes beneath the ice.  The mechanics of the process by which               sediments are entrained and concentrated are poorly understood.                                                                                                 Preliminary studies and laboratory tests indicate that wave action              predominates in transporting suspended sediment to the ice cover.  This         project will develop a theoretical model of such a transport mode and           test the model with an oscillating wave tank which will quantify the            retained sediment as a function of wave frequency and experiment                duration.  The expectation is that the experimental data will allow a           prediction of the subsequent sediment concentration in the natural              environment as a function of regional climatic conditions and the ocean         wave and current regime.
