Location and Characteristics of the North Water Polynya
The North Water Polynya is located in the northern part of Baffin Bay, between Greenland and Canada’s Ellesmere Island. It covers an area of approximately 85,000 square kilometers, making it one of the largest polynyas in the Arctic. The polynya is characterized by its persistent open water, even during the winter months when the surrounding sea ice is typically thick and extensive.
The physical characteristics of the North Water Polynya are unique and contribute to its persistence. The polynya is located at the confluence of two major ocean currents, the West Greenland Current and the Labrador Current. These currents bring relatively warm water from the south into the polynya, preventing it from freezing over completely. Additionally, the polynya is influenced by strong winds that help to keep the ice at bay.
Formation and Persistence of the North Water Polynya
Several factors contribute to the formation and persistence of the North Water Polynya. One key factor is the confluence of warm ocean currents mentioned earlier. The West Greenland Current brings relatively warm water from the south, while the Labrador Current brings cold water from the north. When these currents meet at the North Water Polynya, they create a dynamic environment that prevents the polynya from freezing over completely.
The persistence of the North Water Polynya can also be attributed to the strong winds in the region. These winds help to keep the ice at bay, preventing it from closing off the polynya. Additionally, the polynya is located in an area where there is relatively little precipitation, which means that there is less fresh water input to the polynya. This lack of fresh water helps to maintain the salinity of the polynya, which in turn helps to prevent freezing.
When compared to other polynyas in the Arctic, the North Water Polynya stands out for its size and persistence. While many polynyas in the Arctic are seasonal and only exist during certain times of the year, the North Water Polynya remains open throughout the year. This makes it an important and unique feature of the Arctic ecosystem.
