Involving GLOBE Schools in Study of the Stable Isotope Composition of Precipitation in Croatia

Students interested in the GLOBE program collect and determine amounts of daily precipitation, measure air temperature and send monthly averaged water samples to the Stable Isotope Laboratory (SILab)at Rijeka University. At the SILab, samples are analysed for their conductivity, pH, dissolved oxygen, salinity and isotopic composition in regards to delta2H and delta18O. The delta-values are determined in a Thermo-Finnigan DeltaplusXP mass spectrometer. The first results of this projects already demonstarte the complexity of the meteorological situation in the country, it is appropriate to briefly look at the location of the country and corresponding implications.
