ISS011-E-07865 (3 June 2005) --- Aral Sea coastlines in Kazakhstan are featured in this image photographed by an Expedition 11 crewmember on the International Space Station. The arrow-shaped island in the Aral Sea once was a 35 kilometer-long visual marker, indicating the Aral Sea to astronauts. This 2005 image shows how much the coastline has changed as the sea level has dropped during the last three decades and shows that the island is now part of the mainland. Deep blues and greens indicate the water-covered areas. The exposed sea floor is characterized by old shorelines (parallel lines surrounding the island) and outlines of ancient deltas.
