Microbiological and Geochemical Survey of CO₂-Dominated Mofette and Mineral Waters of the Cheb Basin, Czech Republic.

ABSTRACT: The Cheb Basin (NW Bohemia, Czech Republic) is a shallow, neogene intracontinental basin. It is a non-volcanic region which features frequent earthquake swarms and large-scale diffuse degassing of mantle-derived CO₂ at the surface that occurs in the form of CO₂-rich mineral springs and wet and dry mofettes. So far, the influence of CO₂ degassing onto the microbial communities has been studied for soil environments, but not for aquatic systems. We hypothesized, that deep-trenching CO₂ conduits interconnect the subsurface with the surface. This admixture of deep thermal fluids should be reflected in geochemical parameters and in the microbial community compositions. In the present study four mineral water springs and two wet mofettes were investiga
