A polynya is an area of open water that is surrounded by sea ice, typically found in polar regions. These areas can form in ice-covered seas due to various factors such as ocean currents, wind, and differences in water temperature. Polynya can be important for ecological reasons, as they provide vital habitats for marine life, including seals, birds, and other species. They also play a significant role in regulating climate and ocean circulation by influencing heat exchange between the ocean and the atmosphere.
