Isotopes without borders & Isoscapes


  • Rainfall


  • Groundwater


  • Surface water


In the past 6 years, our group has been involved in different sampling campaigns across Latin America to improve the understanding of spatial-temporal isotopic patterns in rainfall (including tropical cyclones), shallow and deep groundwater, surface water, volcanic and hydrothermal systems. The main goal is to conduct rapid and robust stable isotope assessments to shed light on rainfall dynamics and groundwater recharge processes to enhance water resources management plans under a changing climate.
