New images of sunken Titanic released

Etheral views of Titanic's bow (modeled) offer a comprehensiveness of detail never seen before. The optical mosaics each consist of 1,500 high-resolution images rectified using sonar data.

With her rudder cleaving the sand and two propeller blades peeking from the murk, Titanic's mangled stern rests on the abyssal plain, 1,970 feet south of the more photographed bow. This optical mosaic combines 300 high-resolution images taken on a 2010 expedition. (Copyright 2012 RMS Titanic, Inc.; produced by AIVL, Woods Hole Oceanographic Institute)

This composite image, released by RMS Titanic Inc., and made from sonar and more than 100,000 photos taken in 2010 from by unmanned, underwater robots, shows a small portion of a comprehensive map of the 3-by-5-mile debris field surrounding the stern of the Titanic on the bottom of the North Atlantic Ocean. The luxury passenger liner sank about 375 miles south of Newfoundland, Canada, after striking an iceberg on its maiden voyage from England to New York on April 15, 1912, killing more than 1,500 people.

The last "davit" remaining on the wreck of RMS Titanic. These lifeboat cranes were used to hoist the ship's wooden lifeboats over the side and into the water during Titanic's sinking. Many of the boats launched soon after the sinking were not close to fullpassengers refused to believe the seriousness of the situation. (AP Photo/RMS Titanic Inc)

This August 2010 photo provided by RMS Titanic Inc., shows the port side of the bow section. The rip in the hull can be seen clearly at right, with the stern coming to rest several thousand feet away.
