oxygen isotopic composition (δ 2 H and δ 18 O) a number of processes in the field of hydrogeology can be quantified and qualify very well. Furthermore, these stable isotopes provide an insight to hydrological [...] laser beam being mirrored by a high-reflecting mirror again and again. In this case, the laser beam can reach a path length of up to 2500 m. The result is a very good and clear separation of the different [...] adsorption lines of each water molecule, wherein the total occurrence of the individual molecules can be quantified by the magnitude of the absorbance at a wavelength of about 1390 nm. After that, the
