Sažetak
The main objective of GNIP (IAEA/WMO Global Network for Isotopes in Precipitation) has been the systematic collection of basic data on isotope content (3H, 2H/1H, 18O/16O) in precipitation on a global scale to determine their variations in precipitation and to provide basic isotope data for the use of isotopes in hydrological investigations. GNIP has been active since 1961 and Zagreb station has been part of it since 1976 (1). In 2000 the IAEA started the new Co-ordinated Research Programme (CRP) entitled "Isotopic composition of precipitation in the Mediterranean Basin in relation to air circulation patterns and climate". The program aims to identify and better define the interactions between climatic conditions and isotopic composition of precipitation in the Mediterranean Basin. The obtained data will be used in global circulation models of the atmosphere, which generally need better definition on the Mediterranean basin, and as an impact on catchment and surface water systems, as well as in marine environment studies in the Mediterranean Sea. In the frame of this CRP we started collecting monthly precipitation in September 2000 at 4 marine stations at the Adriatic coast, Croatia (Malinska, Krk Island, N Adriatic ; Zadar, mid-Adriatic coast ; Dubrovnik, S Adriatic coast ; Komiža, Vis Island, S Adriatic). Additionally, we also collect samples at 2 continental stations, Zavižan, Mt. Velebit (alt 1594 m, close to Adriatic coast) and Zagreb-Grič, N Croatia (alt 157 m). Tritium activity of monthly precipitation from these stations will be presented. The influence of different climates (Mediterranean climate, typical continental climate and mountain-type continental climate) and seasonal fluctuations of 3H in precipitation will be discussed.
