The RMS Titanic has been a point of cultural fascination since the ship first sank 100 years ago. Numerous exploratory missions have been made to the wreckage over the years, but with the help of a new sonar survey map the first comprehensive exploration of the site has been completed and National Geographic has the pictures. Several mosaics, each made up of over a thousand images each, provide the first glimpses of the wreckage as a whole, all in high-resolution detail. They create a haunting and melancholy look back at a moment of tragedy, frozen in time some 12,000 feet beneath the surface of the ocean. The pictures are available in the National Geographic print edition, on its website, or in the magazine's iPad edition.
