Abstract
If an oil spill occurs under pack ice fields in the ocean, oil would spread beneath the ice cover and then trapped into recesses under pack ice. In this paper the method for separating oil that trapped into recesses beneath the pack ice is investigated. In this method, it is proposed to remove oils from recesses by introducing air bubbles and flush out by relative velocity between ice and seawater. In order to create relative velocity between ice and seawater, authors are proposing ice booming to control ice movement. A series of experiments for separating oil, which trapped into recesses of model ice, were carried out by using water tank. From the experimental results, the behavior of oil and air bubbles was investigated.
