Due to its extreme salinity and high Mg concentration the Dead Sea is characterized by a very low density of cells most which are Archaea. We discovered several underwater fresh brackish water springs in harboring dense microbial communities. provide first characterization these communities, discuss their possible origin, hydrochemical environment, energetic resources putative biogeochemical pathways they mediating. Pyrosequencing 16S rRNA gene community fingerprinting methods showed that...
Abstract A method to estimate reactive transport parameters as well geometric conduit from a multitracer test in karst aquifer is provided. For this purpose, calibration strategy was developed applying the two‐region nonequilibrium model CXTFIT. The ambiguity of reduced by first calibrating with respect conservative tracer breakthrough and later transferring calibration. were only allowed be within defined sensible range get reasonable values. This applied curves obtained large‐scale test,...
Severe stone deterioration is evident at the Cologne cathedral. In particular, "Drachenfels" trachyte, which was building material of medieval construction period, shows significant structural as well massive formation gypsum crusts. The present article investigates crust on limestone, sandstone, and volcanic rock from cathedral Xanten Altenberg cathedrals. These three buildings, showing varying degrees deterioration, are located in different areas exposed to industrial, urban, rural...
