  Title: STS-54 Earth observation of a ship wake in the Bay of Bengal
  Description:
  STS-54 Earth observation taken aboard Endeavour, Orbiter Vehicle (OV) 105, 
  is of a ship wake in the Bay of Bengal.  The sun glint pattern on the ocean
  reveals many patterns of sea surface roughness related to currents, waves, 
  wind roughening, and biology that and are not apparent when the ocean is 
  viewed away from the sun's reflection.  In this view of the Bay of Bengal, 
  southeast of Madras, India, sun glint highlights convergence zones between 
  ocean currents (bright, linear features), a eddy, and the wake of a ship. 
  In  several locations where the ship has passed areas of current shear, the
  ship  wake is distorted, indicating the relative current direction.
