Abstract
Provided is a method and a system for removal of oil under ice through an opening made into ice. The system includes oil booms extending under ice in two different directions from the opening so as to constitute an angle of less than 180 degrees between each other; an oil collection device placed in the opening; and a propulsion device placed on the level of the lower surface of ice at a distance from the opening in the area of the angle so as to provide a flow directed towards the opening between the oil booms in the area of the angle.
