Data supporting: Isotopic insights on continental water sources and transport in the mountains and plains of southern South America

The data presented here comprises the stable isotopic composition (δ2H and δ18O) of 1659 samples of precipitation, rivers, groundwater and lakes/ponds samples from a total of 511 sites. This is a composite dataset that includes data from the Global Network of Isotopes in Precipitation (GNIP) and Rivers (GNIR) databases (IAEA/WMO 2019), data extracted from different published articles (cited therein) and data obtained directly by the authors as part of different previous and ongoing projects of our own lab (GEA, IMASL). Excel sheet 1 shows a description/overview of the dataset as displayed in Table 1. Excel sheet 2 shows the dataset, which includes a unique identifying code, type of water sample (precipitation, rivers, groundwater, and lakes), name of location, sampling point date, latitude, longitude and elevation, and the dual isotopic composition (δ2H and δ18O).

We acknowledge all contributing researchers to GNIP and GNIR databases, as well as the effort of the IAEA for initiating and maintaining these open access global initiatives. We also acknowledge the authors of the papers cited in the dataset and all GEA lab staff that contributed to the sampling and/or to measuring the stable isotopic compositions of waters included in this database.
