Laser Induced breakdown spectroscopy

We are investigating the application of laser-induced plasmas as a general method for in situ multi-element analysis of solids and liquids at sea. In addition to our laboratory based experimental facilities, we have also developed and deployed a 3000m depth rated LIBS device, called the I-SEA (In-situ Seafloor Element Analyser), and the 2nd Generation ChemiCam, which has been successfully deployed to analyse Black Ores off Okinawa at over 1000m depth.
