Danube Delta. Satellite image focused on the northernmost Chilia (or Kilia) lobe of the Danube Delta, the second largest river delta in Europe. This delta is made up of a number of lobes and drains over 800,000 square kilometres of land across 19 countries. Where the river reaches the Black Sea (upper right), another remarkable delta has formed an area dubbed the 'Everglades of Europe'. Imaged by the Advanced Land Imager (ALI) on NASA's Earth Observing-1 (EO-1) satellite, on 5th February 2013.
