This paper presents underwater archaeology research being conducted in Saint-Pierre Martinique (FWI) since the 1970’s focusing on port dump and shipwrecks vestiges. Doban port dump site as well as the identified Biscaye and unidentified Guinguette wreck sites are presented. Both the dump and wreck sites demonstrate the importance of maritime activity at the main port of Martinique and of the French West Indies in general, that stopped because of the eruption of Mount Pelée in 1902. Archaeological research has traditionally focused on the wrecks from this tragic event, but there is also real potential for research into more ancient sites.
