Figure 5.11
A visual marker for the unusually mild winter over the northern United States and southern Canada was the lack of an extensive ice cover on the St. Lawrence Seaway. An early January 1998 view of the Isles de la Madeleine (NASA photograph NASA6-708-003), usually icebound by midwinter, contrasts with a February 1997 regional view (NASA photograph NM22-778-081), which shows extensive ice cover in the southeastern Gulf of St. Lawrence between Newfoundland (foreground) and Nova Scotia (left of center). The arrow points to the Isles de la Madeleine.
