  Title: STS-56 Earth observation of the Strait of Gibraltar
  Description:
  STS-56 Earth observation taken aboard Discovery, Orbiter Vehicle (OV) 103, 
  is of the Strait of Gibraltar.  A small bank of clouds marks the passage 
  between Spain and Morocco at the western edge of the Mediterranean Sea. 
  This  passage, one of the two Pilars of Hercules of the Ancient Greeks, is
  now  known as the Strait of Gibraltar.  The cities of Cadiz on the Atlantic
  Coast  of Spain and Malaga on the Mediterranean coast, as well as Tangier,
  Morocco  (facing the strait), can be seen.  According to NASA scientists
  studying the  STS-56 photos, a subtle difference in the water color on the
  Atlantic side  suggests that a pulse of surface water had recently flowed
  out of the  Mediterranean into the Atlantic.
