The wide, multi-island zone in the Rio Negro (Black River) shown in this astronaut photograph from September 2, 2006, is one of two, long “archipelagoes” upstream of the city of Manaus (not shown) in central Amazonia. Sixty kilometers of the total 120-kilemeter length of this archipelago appear in this image.
These images show how terrestrial water storage in the four major sub-basins of the United States’ Mississippi River basin differed from average in January and July 2005.
