Finding the Titanic How did marine science help find the Titanic?

Finding the Titanic April 12, 1912

Finding the Titanic September 1, 1985 a U. S. -French expedition located the Titanic n Goes down in the North Atlantic n 12, 000 ft deep (over 2 miles) on the seafloor n

Finding the Titanic n Dr. Robert Ballard and Jean-Louis Michel led the expedition

Finding the Titanic

Finding the Titanic n Technology used to locate: – Side-scan sonar and video which were on a robot named Argo – A submersible named Alvin to explore a great depth – A R. O. V. named Jason to search into the Titanic itself

Finding the Titanic n Old Theory (no technology) – An iceberg had sliced open huge holes below the water line flooding the hull – Water filled the ships 6 out of 16 compartments by overflowing one bulkhead and spilling over to the adjacent bulkhead (like an ice cube tray)

Finding the Titanic n The video from Argo, Alvin, and Jason help provide important information about the actual reason for the sinking

Finding the Titanic n New Theory (technology) – The actual holes created by the iceberg collision were not large enough to have caused the ship to sink in under three hours

Finding the Titanic n New Theory (technology) – The rivets holding the over lapping steel plates of the hull “popped” causing water to enter at every joint

Finding the Titanic n New Theory (technology) – John Hopkins did a study and found the rivets were incorrectly made and under cold temperature were not as strong

Finding the Titanic

Finding the Titanic n New Theory (technology) – Had the steel rivets held, the ship would have taken many more hours to sink (probably giving the Carpathia, rescue ship, enough time to make it to the Titanic’s location)

Finding the Titanic n Statistics: – – Total on Board: 2229 Total Survived: 713 Total Crew on Board: 913 Total Crew Survived: 215

Finding the Titanic n Statistics: – Total First Class on Board: 325 – Total First Class Survived: 202 – Total Second Class on Board: 285 – Total Second Class Survived: 118 – Total Third Class on Board: 706 – Total Third Class Survived: 178

n Anatomy of a disaster

Finding the Titanic n Watertight Doors

Finding the Titanic n What was learned: – Ocean liners must carry sufficient lifeboats to accommodate all persons – Bulkheads must not allow water to pour over they must be watertight – Iceberg monitoring ships and systems – Movement of sea lanes father south in the winter months
