  • Assessing cave internal aerology in understanding carbon

    Carbon dioxide gas is a key component in dissolution and precipitation of carbonates in karst and cave systems. Therefore characterizing the internal aerology of a cave is essential to obtain the spatiotemporal distribution of temperature and CO 2 level. In this research Lascaux Cave (France) an important adorned cavity was studied.
