An expedition team using sonar imaging and robots has created what is believed to be the first comprehensive map of the entire Titanic wreck site 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.
