Geochemical, isotopic and noble gas dataset from submarine groundwater discharge at Izola (Slovenia, northern Adriatic Sea)

This dataset contains physical, chemical (major ions, trace elements), isotopic (δ18O, δ2H, δ34S, 87Sr/86Sr, 3H), and noble gas measurements from submarine groundwater discharge (SGD) systems near Izola (Slovenia, northern Adriatic Sea). The dataset supports a study on the pockmark morphology, geochemical characteristics, and origin of the SGD near Izola. Detailed information on sampling procedures, analytical methodologies, and data limitations is provided in the associated publication, which is essential for correct interpretation and reuse of the dataset. Users are requested to cite both the dataset and the related publication when using these data.
