Ice Waves, Greenland
The undulating swirls shown here along the eastern coast of Greenland are slurries of sea ice, newly calved icebergs, and older weathered bergs. During the summer melting season, the southward-flowing East Greenland Current twirls these mixtures into stunning shapes. The East Greenland Current is the major current for transporting sea ice from Greenland into the North Atlantic. The rush of fresh water on an annual basis contributes to the low salinity and cold temperature of the current. In the center of this 2001 Landsat 7 image, the exposed rock of mountain peaks, tinted red, appears as an intricate network of glacier-cut fjords.
