Argo
Quick Summary
The Argo was a submersible sled, approximately 16 feet long, equipped with a remote-controlled camera. It was developed by the Institut Français de Recherche pour l'Exploitation de la Mer (IFREMER) and used by Robert Ballard's expedition. The primary purpose of the Argo was to test its capabilities and transmit live underwater images.
In 1985, the Argo was instrumental in the discovery of the wreck of the RMS Titanic, located at a depth of about 12,500 feet in the Atlantic Ocean. The submersible transmitted the first underwater images of the ship, revealing its condition and aiding in subsequent detailed examinations of the wreck.123
