On March 13, 1770, as a consequence of a storm the war corvette H.M.S. SWIFT strand and sink at the Patagonian coast in the Deseado Ria, Santa Cruz, Argentina.

In this work has identified the composition of eight pieces of metal using the LIBS (laser induced breakdown spectroscopy) in order to implement the appropriate conservation treatment. It also has the laser cleaning of some of these objects, including buckles and silver pieces.
