Development of hydrocarbon is in underway in the offshore area of Sakhalin island, which is located just to the north of Hokkaido, Japan. It is planned to have the development in the year-round basis including winter, when the sea is covered by ice, in the near future. This has provoked serious concern over the possibility of oil spilling in ice, especially in Hokkaido that is sure to be affected by such pollution. Knowledge on oil spilling in ice, however, is limited compared with that in open water conditions. In view of the situation a research project had been carried out to study the behavior and recovery of oil spilled in ice-covered waters. Five organizations, Hokkaido University, Iwate University, National Maritime Research Institute, Civil Engineering Research Institute of Hokkaido and North Japan Port Consultants, participated in the project. This report describes the results of a study on the behavior of oil spilled in ice-covered waters, that was made as a part of the project. The study focused the spreading behavior of oil under an ice cover and the encapsulation of the oil in ice.
