The presence of a shipwreck in deep waters off the Dry Tortugas, a group of islands located at the westernmost point of the Florida Keys, first gained attention in 1965 when the shrimp trawler Trade Winds snagged in its nets various metal artifacts, pieces of ship’s rigging and an ornately carved railing.
Also ensnared were three large intact pottery amphorae later identified as colonial-era Spanish olive jars used for the storage and shipment of various goods. At the time, the depth of the water made exploration of the site impractical.
In 1989, the "Tortugas" wreck was located over 405 meters below the ocean surface by deep-ocean shipwreck exploration pioneers Seahawk Deep Ocean Technology.
The "Tortugas" project was the first deep-ocean remotely-operated archaeological excavation of a shipwreck site to be conducted anywhere in the world. Nearly 17,000 artifacts, including some as small as seeds and pearls, were recovered from the site during the 1990-1991 excavation seasons.
Research suggests that the "Tortugas" wreck is likely the remains of the 117-ton Buen Jesús y Nuestra Señoradel Rosario, one of the vessels sailing with the 1622 Tierra Firme treasure fleet that also included the Nuestra Señora de Atocha and the Santa Margarita, bound for Spain and all loaded with the wealth of the New World.
