Ocean currents and sea ice extent
Arctic Ocean circulate in a large clockwise rotational pattern moving from east to west around the polar ice cap. This rotating pattern, known as a gyre, occurs as a result of the clockwise winds that typically occur in this region. The Barents region is affected by this and the ice edge extent in the Arctic.
