The image is an animation of MASIE ice charts over the last three weeks from Oct.1 to yesterday, Nov.20, 2019. At the top is Kara Sea icing, along with Barents, both higher than the 12 year average at this time. On the left Laptev and East Siberian have filled with ice. Chukchi on the bottom was mostly water, but in 3 weeks tripled from 170k km2 up to 518k km2, now 54% of March maximum. Bottom right shows Beaufort Sea and CAA filled with ice. On the right, Hudson Bay has begun freezing down its west coast, while Baffin Bay is freezing southward. Both of these bays are slower than average and a main reason 2019 NH ice extent remains below average presently.
