註釋The behaviour of crude oil and fuel oil droplets is observed in a watercolumn containing a known density gradient. Of particular interest is thebuoyant behaviour of the oil because that behaviour influences the timeperiod during which the oil may be submerged, and thus subject todissolution, diffusion and advective processes in the water column. Asystem was developed in which a stratified water column was created in aglass-walled tank with a facility to measure density as a function of height using the "Westphal Balance" principle. Several oils were tested:fresh, weathered (evaporated) and emulsified (to form water in oilemulsions) and their behaviour observed, recorded and intepreted. A complementary theoretical treatment is presented.
