Odyssey Marien Exploration Reports

In ten papers Odyssey Marine Exploration presents the technology, methodology and archaeological results from four deep-sea shipwrecks and one major survey conducted between 2003 and 2008. The sites lie beyond territorial waters in depths of up to 820 metres off southeastern America and in the Straits of Gibraltar and the English Channel. Exclusively recorded using robotic technology in the form of a Remotely-Operated Vehicle, the wrecks range from the major Royal Navy warships HMS Sussex (1694) and the unique, 100-gun, first-rate HMS Victory (1744)to the steamship SS Republic (1865) and a mid-19th century merchant vessel with a cargo of British porcelain. Their study reveals that the future of deep-sea wreck research has arrived, but also that many sites are at severe risk from destruction from the offshore fishing industry.

Oceans Odyssey 2 presents the results of the discovery and archaeological survey of ten deep-water wrecks by Odyssey Marine Exploration. In the Western Approaches and western English Channel, a mid-17th century armed merchantman, the guns of Admiral Balchin's Victory (1744), the mid-18th century French privateer La Marquise de Tourny and six German U-boats lost at the end of World War II are examined in depth. From the Atlantic coast of the United States, the Jacksonville 'Blue China' wreck's British ceramics, tobacco pipes and American glass wares bring to life the story of a remarkable East Coast schooner lost in the mid-19th century. These unique sites expand the boundaries of human knowledge, highlighting the great promise of deep-sea wrecks, the technology needed to explore them and the threats from nature and man that these wonders face. Challenges to managing underwater cultural heritage are also discussed, along with proposed solutions for curating and storing collections.

In 1990 Seahawk Deep Ocean Technology of Tampa, Florida, commenced the world's first robotic archaeological excavation of a deep-sea shipwreck south of the Tortugas Islands in the Straits of Florida. At a depth of 405 meters, 16,903 artefacts were recovered using a Remotely-Operated Vehicle. The wreck is interpreted as the Buen Jesús y Nuestra Señora del Rosario, a small Portuguese-built and Spanish-operated merchant vessel from the 1622 Tierra Firme fleet returning to Seville from Venezuela's Pearl Coast when lost in a hurricane. Oceans Odyssey 3 introduces the shipwreck and its artefact collection — today owned and curated by Odyssey Marine Exploration — ranging from gold bars to silver coins, pearls, ceramics, beads, glasswares, astrolabes, tortoiseshell, animal bones and seeds. The Tortugas shipwreck reflects the daily life of trade with the Americas at the end of the Golden Age of Spain and presents the capabilities of deep-sea robotics as tools for precision archaeological excavation.
