Descr: The Institute of Geophysics in Prague has organized an experiment that is designed to extend and tie to the CELEBRATION 2002 effort. Polish and German groups have also committed to providing some shot points. A network of profiles will be recorded during 1 main deployment that will thus provide 3-D coverage. This effort will fill in a major gap in our knowledge of the lithospheric structure of the Bohemian Massif – Sudetes area.
