of that resolution. this will allow scientists, historians to really understand how the titanic came to be where it is. and it s also a snapshot in time. the titanic was scanned last summer. submersibles were deployed remotely controlled from a ship. they travelled the length and breadth of the wreck back and forth. 700,000 images were taken from every angle to build up an exact 3d reconstruction. the wreck is in two parts. the bow is still instantly recognisable more than 100 years after it sank. 800 metres away, the stern, though, is a chaotic mess of metal. it collapsed as it corkscrewed into the sea floor. in the surrounding, debris filled items are scattered, ornate metalwork, unopened champagne bottles and personal possessions too.
