Weddell Polynya information


The Weddell Polynya, or Weddell Sea Polynya, is a polynya, or irregular area of open water surrounded by sea ice, in the Weddell Sea of the Southern Ocean off Antarctica and near the Maud Rise.[1][2] The formation of the polynya exposes relatively warmer ocean waters (at surface freezing temperatures of –1.9 °C) to a cold atmosphere, leading to a large exchange of heat which drives deep convection in the ocean, often reaching depths of 1,000 to 2,000 meters.[3]
