| The oceanographer and explorer Robert Ballard (on the right) and the photographer Emory Kristof stand next to the French sonar search instrument SAR in this 1985 view. SAR was used in the initial reconnaissance of the seabed that led to the discovery of the wreck of the Titanic. Ballard has used similar methods to pinpoint the location of many other famous wrecks in the years since. | ||||||
