Major ions, Stable water isotopes, Microparticle (dust, diatoms, pollen and spores) and electrical conductivity records from the first Cordillera Darwin ice core 2017 - 2020 CE

This dataset presents the microparticle (dust, diatoms, pollen and spores), stable water isotope, liquid electrical conductivity and major ion concentrations from the first ice core drilled from Cordillera Darwin, Chile (2017-2020 CE). These records were presented in Tetzner et al. (2025) to assess the preservation of local-to-regional environmental information in the firn. Results obtained from the analysis of this dataset highlighted the potential of high elevation sites in the Cordillera Darwin Icefield to hold valuable paleoenvironmental records directly from the core of the Southern Hemisphere Westerly wind belt. This dataset was created with the support of the Dieter R Tetzner's National Geographic Early Career Grant 2019.
