Arctic Ocean almost totally ice-covered

  • Purple signifies sea-ice thickness of approximately ½ to 1½ meters (20 inches to 5 ft).
  • Blue or green signifies 1½ to 3 meters ( 5 ft to 10 ft) of ice.
  • Yellow or orange signifies 3 to 4 meters (10 ft to 13 ft) of ice.
  • Red signifies 4 to 5 meters (13 ft to 16 ft) of ice.
  • White signifies zero thickness of ice.
I don’t see much open water. Do you?
