Abstract
This paper reviews stable isotopic data concerning spring water in Greece in addition to new measurements (59); their spatial variations are investigated in order to provide basic information and identify the locally significant parameters that affect stable isotopic distributions. The area of interest was partitioned into eight sections according to geographical location and climatic characteristics. Local spring water lines (LSWLs) are more or less consistent throughout the country. High-resolution isoscape maps of spring freshwater (Cl− < 200 ppm; and T < 25 °C) for both δ18O and δ2H were generated, revealing several interesting features such as the effect of Pindos ridge, a strong climatic signal in southern Greece and indications of seawater intrusion in flat coastal areas.
Highlights
The isotopic composition of spring water in Greece is mainly affected by: its location within the Mediterranean basin; a complex morphology dominated by the presence of the Pindos ridge range crossing Greece from
On the basis of that division and using the obtained average isotopic values, local spring water lines (LWSLs) for spring water were calculated for each region, using the ordinary least squares regression (OLSR) and the generalized least squares (GENLS) that is suitable for cases least squares regression (OLSR) and the generalized least squares (GENLS) that is suitable for cases where the errors of both x- and y-values are not constant and can incorporate analytical or other

Summary
The isotopic composition of spring water in Greece is mainly affected by: its location within the Mediterranean basin (the eastern Mediterranean basin is dominated by air masses on the leeside of the continental areas due to intense evaporation of seawater in conditions of moisture deficit [1,2]);. The use of stable isotopic analyses for investigating paleodiet [3,4], and paleoclimate has generally proceeded on two fronts: evaluation of the stable isotope compositions in various natural systems to understand the biological and geological processes, and subsequently to generate predictive models These models incorporate spatially variable isotopic parameters to construct isotope “iso-land-scapes”. We present high-resolution isoscape maps of the spatial distribution of spring water δ18 O–δ2 H that could provide important information for hydrological studies and represent a reference for the assessment of future changes. These maps are the result of on-going research and are being constantly improved (with new samples and different sampling years). Composition of the spring waters (including springs with high Cl− concentrations) and evaluate the mixing ratio with seawater
