Aerial slices II: Rivers

northern Siberia to the east of the Taz Rivernorthern Siberia to the east of the Taz River


This image pair shows lakes dotting the tundra in northern Siberia to the east of the Taz River (bottom left). The tundra vegetation is colored a faded red, while lakes appear blue or blue-green. White arrows point to lakes that have disappeared or shrunk considerably between 1973 (top) and 2002 (bottom). After studying satellite imagery of about 10,000 large lakes in a 500,000-square-kilometer area in northern Siberia, the scientists documented a decline of 11 percent in the number of lakes, with at least 125 disappearing completely. These images use near-infrared, red, and green wavelength data from the Landsat MSS sensor (1973) and the Landsat ETM+ sensor (2002). - NASA Observatory
