Sažetak
At the Stable Isotope Laboratory at Rijeka University (SILab Rijeka) we monitor the stable isotope composition (δ18O, δ2H) of precipitation in Croatia. Our data base contains about 50 stations distributed all around the country. Their different latitudes, longitudes and altitudes give information in great detail, including the influence of the topographic structure on the precipitation in this south-eastern part of Europe, as well as the complex interplay of the different climate conditions in the area. Within a few hundred kilometers, the stable isotope values display a significant change from the maritime character in the South (mean δ18O around –6 to –8 ‰) to the continental behavior in the North (mean δ18O around –8 to -11 ‰). In addition, depending on the location, the mean δ18O values vary with altitude at a rate between approximately −0.2‰ /100m to −0.4‰ /100m, respectively. Particular attention is given to the correlation between δ18O and δ2H (the Local Meteoric Water Line, LMWL), as well as the d-excess d = δ2H − 8٠δ18O.
