MISR images of tropical northern Australia acquired on June 1, 2000
(Terra orbit 2413) during the long dry season. Left: color composite of
vertical (nadir) camera blue, green, and red band data. Right:
multi-angle composite of red band data only from the cameras viewing 60
degrees aft, 60 degrees forward, and nadir. Color and contrast have been
enhanced to accentuate subtle details. In the left image, color
variations indicate how different parts of the scene reflect light
differently at blue, green, and red wavelengths; in the right image
color variations show how these same scene elements reflect light
differently at different angles of view. Water appears in blue shades in
the right image, for example, because glitter makes the water look
brighter at the aft camera's view angle. The prominent inland water body
is Lake Argyle, the largest human-made lake in Australia, which supplies
water for the Ord River Irrigation Area and the town of Kununurra (pop.
6500) just to the north. At the top is the southern edge of Joseph
Bonaparte Gulf; the major inlet at the left is Cambridge Gulf, the
location of the town of Wyndham (pop. 850), the port for this region.
This area is sparsely populated, and is known for its remote,
spectacular mountains and gorges. Visible along much of the coastline
are intertidal mudflats of mangroves and low shrubs; to the south the
terrain is covered by open woodland merging into open grassland in the
lower half of the pictures.

Russias Volga River is the largest river system in Europe, draining over 1.3 million square kilometers of catchment area into the Caspian Sea. The brackish Caspian is Earths largest landlocked water body, and its isolation from the worlds oceans has enabled the preservation of several unique animal and plant species. The Volga provides most of the Caspians fresh water and nutrients, and also discharges large amounts of sediment and industrial waste into the relatively shallow northern part of the sea.
