- The existence of the North Water Polynya is dependent on cold, stable winters that form an ice bridge between Canada’s Ellesmere Island and Greenland. This ice bridge prevents polar pack ice from flooding into the polynya. Prevailing north winds push any ice that forms in the polynya to the south, helping to keep it clear.

The North Water Polynya (NOW), or Pikialasorsuaq to Inuit in Greenland and Sarvarjuaq to Inuit in Canada, is a polynya (area of year-round open water surrounded by sea ice) that lies between Greenland and Canada in northern Baffin Bay.
The North Water Polynya, called Sarvarjuaq in Inuktitut and Pikialasorsuaq in Greenlandic, is one of the planet’s most productive ocean ecosystems. An open-water area surrounded by ice in northern Baffin Bay, it supports an abundance of marine mammals, including narwhal, walrus, seals and polar bears, as well as seabirds and a variety of fish.
Pikialasorsuaq (The North Water Polynya), or “The Great Upwelling” in Greenlandic, is the largest Arctic polynya and the most biologically productive region north of the Arctic Circle. Pikialasorsuaq has been recognized by Inuit for generations as a critical habitat.
Oct 20, 2023 · Using simple, animated graphics, the video illustrates how the North Water Polynya—an open area of sea water, surrounded by ice—forms each winter. An ice bridge emerges during the cold months as Nares Strait freezes between Canada and Greenland, blocking the flow of ice into northern Baffin Bay.
