Its nutrient-rich upwelling waters provide feeding grounds to many birds, fish and marine mammals that have sustained and nourished Inuit on both sides of the polynya for millennia. Yet, increasing temperatures and the impacts of human activities put the waters and ice of the Pikialasorsuaq, the ecosystems and the Inuit communities that depend on them, under pressure. To safeguard and monitor the changing polynya, an Inuit-led management regime is being established – a prime example of an Indigenous-led ecosystem approach to management. Between Avanersuaq, Northern Greenland and Ellesmere Island in the Qikiqtani region of Nunavut lies one of the largest Arctic polynyas, an area of year-round open water surrounded by sea ice. In Kalaallisut, the language of the Inuit of Western Greenland, the region has been called Pikialasorsuaq, meaning “great upwelling,” a reference to the warm, nutrient-rich waters that sustain one of the Arctic's most biologically productive ecosystems – but the North Water Polynya goes by many names (see box).
