Hudson Bay

Sitting just south of the Arctic Circle in Canada, the cold waters of
Hudson Bay wear a thick coat of ice each winter. Freeze-up beings in
October or November and, as days lengthen and temperatures rise in late
spring and summer, the icy coating melts. Traditionally ice break-up
begins in May or June and Hudson Bay become ice-free by late July or

On April 15, 2021, the Moderate Resolution Imaging Spectroradiometer
acquired a true-color image of the first signs of spring ice break-up
in Hudson Bay.

Warming air temperatures have thinned the ice near the southeastern
eastern shore of Hudson Bay and James Bay (the southern extension of
Hudson Bay) The warm temperatures, combined with strong winds which
push the ice away from the shore, have created several areas of open
water and churned the ice into chunks in several places.
