Light brown streamers of dust were blowing southward off the southern coast of Iceland on October 5, 2004. Strong winds pushed by a large low-pressure system to the southeast (not shown in this image) were sweeping the dust off the land and carrying it for more than a hundred kilometers over the North Atlantic.
