Melting Ice Across Hudson Bay Canada

March 1, 2013
Fields of sea ice melt in northeastern Canada’s Hudson Bay in this false-color Aqua MODIS image acquired on July 5, 2003. The ice in this image is bright turquoise blue, while liquid water is black. Land appears in shades of green and brown, and clouds are white and light blue. During the winter, sea ice accumulates to the point where the ice is so thick as to prohibit the passage of all but the sturdiest of ice-breaking ships, and oftentimes prohibits even them. But as the spring and summer seasons heat the water and air, the ice melts and breaks up, leaving what looks like slush on the water surface. The Bay is generally ice-free and navigable from mid-July to October.
