One year ago, in late February 2000, MISR began acquiring Earth
imagery. Its "first light" images showed a frozen James Bay in the
Ontario-Quebec region of Canada. These more recent nadir-camera views
of the same area illuminate stark contrasts between summer and winter.
The left-hand image was acquired on August 9, 2000 (Terra orbit 3427),
and the right-hand image is from January 16, 2001 (Terra orbit 5757).
James Bay lies at the southern end of Hudson Bay. It is named for the
English explorer Thomas James, who first explored the area in 1631
while searching for the Northwest Passage. Visible in these images are
some of the many rivers that flow into the bay; starting at the
southern tip and moving clockwise on the western side are the
Harricana, Moose, Albany, and Attawapiskat. The latter enters the bay
just to the west of the large, crescent-shaped Akimiski Island.
