Titanic's Propeller

Photograph by Emory Kristof

In the early morning hours of September 1, 1985, oceanographer Robert Ballard and photographer Emory Kristof found and photographed the shipwreck of the century, the R.M.S. Titanic. Kristof and his crew used a submersible search vehicle and a towed sled with a still camera to shoot more than 20,000 frames, including this one of the ocean liner's starboard propeller.
