The HCMR group conducted two sampling campaigns in surface waters and groundwaters of the Sperchios River catchment in January 2025. The campaigns involved the collection of samples for the analysis of stable isotope ratios of water (18O/16O, 2H/1H) and nitrate (15N/14N, 18O/16O). In addition, a rain collector was installed to enable rainwater sampling within the […]

The HCMR group performed two sampling campaigns in surface waters and groundwaters of the Sperchios River catchment in June and November 2024. The campaigns included the collection of samples to be analyzed for water stable isotope ratios (18O/16O, 2H/1H) and 222Rn activity. The analysis of samples for 222Rn activity was done in the field byRead More »
