In 2000, Ballard and his team conducted an expedition that focused on the exploration of the sea bed about 15-30 km west of Sinop, and an additional deep-water survey east and north of the peninsula. Their project had several goals. They sought to discover whether human habitation sites could be identified on the ancient submerged landscape, they examined the sea-bed for shipwrecks, to test the hypothesis that the anoxic waters below 200 m would protect shipwrecks from the expected biological attacks on organic components, and to seek data about an ancient trade route between Sinop and the Crimea indicated by terrestrial archaeological remains. The wreck found provided the team with vast information about both the technological changes and trade that occurred in the Black Sea during a period of political, social and economic transition through their study of the ship’s construction techniques. Studies show that long-distance trading had developed in Sinop as early as 4500 BCE. Sea-trading on the Black Sea was most intense during the period of late antiquity, between the 2nd and 7th centuries CE. Sinop D provides direct evidence for Black Sea maritime trade so well attested by the distribution of ceramics on land. Sinop D provided Ballard and his team with an unprecedented opportunity to document hull construction during a time of transition. When observing the sonar signature of Sinop D, a long, slender upright feature on the sea-bed transformed itself into a wooden mast. Elements rarely present on shallower shipwreck sites are beautifully preserved 200 m below the surface. There are currently few indications of how the planks of Sinop D are held together, as the bulk of the ship remains buried in sediments. There are no mortise and tenon fastenings, and no sewing. Sinop D was originally thought to be one of the earliest lateen-rigged ships available to be studied by archaeologists. However, a 2007 expedition to the site identified what is now believed to be a mast for an, which would suggest a different type of vessel. Some photos are available on line. New technology is currently in development that will allow more thorough and preservative excavations to take place.
