Sažetak
Isotope composition of monthly precipitations (3H, d2H, d18O) during three-year period (Sep. 2000.-Dec.2003) was observed at 6 stations in Croatia, 4 marine and 2 continental stations. Seasonal variations of tritium at maritime stations (mid and south Adriatic coast) are less pronaunced and the mean yearly activities are lower than those at the continental stations. d2H and d18O values of monthly precipitations for all stations were compared with Global Meteoric Water Line. The temperature coefficient (d18O-temperature correlation) and altitut effect for different stations were discussed. Influence of different climate to the isotope composition of precipitation was also discussed. The results of stable isotope compositions in daily precipitation at 1 station in six-month period were also presented as well as 14C activity of atmospheric CO2 in Zagreb area.
