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.

The Tortugas shipwreck excavated at a depth of 405 meters in the Straits of Florida contained a major collection of 3,800 intact and fragmentary olive jars, tablewares, cooking vessels and tobacco pipes. Identified as the Portuguese-built and Spanish-operated 117-ton Buen Jesús y Nuestra Señora del Rosario, the ship’s Seville dominated tablewares are a revealing index of unchanged cultural tastes and continued production at the end of Spain’s Golden Age. For cooking the crew relied on Afro-Caribbean colonoware, possibly the first recorded archaeological evidence of maritime slavery in the Americas fleets. Two tin-glazed plates painted with papal coat of arms – the Keys of Heaven and triple crown – may have been used by Spain-bound clergymen from the newly formed Sacred Congregation of the Propagation of the Faith. Samples of all ceramics were subjected to Inductively-Coupled Plasma Spectrometry (ICPS) analysis to determine vessel origins.Six chapters focus on the tablewares, tin-glazed papal plates, Afro-Caribbean cooking wares, the olive jars, Inductively-Coupled Plasma Spectrometry results, and a study of how the pottery reflects Spanish colonial economic models, also compared to Roman and medieval structures.
