In the Canadian Arctic, there are three types of recurring polynyas that appear in the same locations each year. These polynyas may vary considerably in size and shape between areas and between years in the same area. The ecological importance of these open water areas appears to depend upon the timing of freeze-up and the formation of the polynya, the size of the polynya at the time of maximum ice accumulation, and the pattern of break-up and disappearanceof the polynya"--Abstract.
