Howell Mark I Torpedo No. 24: Discovery, History, Research and Conservation


As one of its many functions, the Naval History & Heritage Command (NHHC) Underwater Archaeology Branch operates the Archaeology & Conservation Laboratory in order to conserve, document, research and curate US Navy's archaeological artifacts.  The Archaeology & Conservation Lab also conducts scientific and historical research to better inform conservation treatments, contribute data to archaeological research questions and help interpret the US Navy's submerged cultural heritage. NHHC's Underwater Archaeology team and conservators from Terra Mare Conservation LLC are working together to document, study and preserve a rare 19th century Howell Mark I torpedo discovered off the coast of San Diego in 2013.  This poster highlights the history, discovery, research and conservation of a truly unique piece of US Navy history.
