AB Nowadays, one of the most important areas of interest in archeology is thecharacterization of the submersed cultural heritage. Mediterranean Sea is rich inarchaeological findings due to storms, accidents and naval battles since prehistorictimes. Chemical analysis of submerged materials is an extremely valuable source ofinformation on the origin and precedence of the wrecks, and also the raw materialsemployed during the manufacturing of the objects found in these sites. Sometimesextracting the archeological material from the marine environment is not practical due tothe size of the sample, or is not permitted by the legislation or preservation practices. Inthese cases, the in-situ analysis turns into the only alternative. The versatility of laserinducedbreakdown spectroscopy (LIBS) has been successfully tested in oceanography.Advantages such as rapid and in situ analysis with no sample preparation make LIBS asuitable alternative for field measurements. Laser Laboratory of the University of Malagais evaluating the capability of stand-off LIBS (ST-LIBS) for seafloor exploration (2000-3000 meters deep). Several experiments including the transmission of laser radiationthrough water or the influence of the range of analysis over LIBS signal, has beenperformed in laboratory inside a water tank. Preliminary results are quite satisfactory andsuggests the possibility of integrating LIBS technology in a remotely operated vehicle(ROV) for geological/mineralogical exploration, cultural heritage investigation and/or theinspection of oil and gas pipelines in the seafloor, among others.
