Shipwrecks were found literally everywhere. Over half of the wrecks date to the Late Roman Period (circa 300-600 A.D.).
Overall, the shipwrecks span from the Archaic Period (700-480 B.C.) to the Classical (480-323 B.C.) and Hellenistic (323-31 B.C.) through the Late Medieval Period (16th century).
The cargoes revealed long distance trades between the Black Sea, Aegean Sea, Cyprus, the Levant, and Egypt in all those periods. At least three ships carried amphoras, or jars, that have not been found previously on shipwrecks.
