Abstract:
Seasonal snow stable water composition (δ¹⁸O, δD, d excess) of snow pits from 11 sample sites along the Chilean Andes, between 33° and 41°S. The snow samples were taken every 5 cm from top to bottom from the shadow side wall. Stable water isotope analyses were carried out at Laboratorio Análisis Isotópicos (LAI) in Viña del Mar, Chile.

Comment:
Isotope measurements were validated with an instrumental deviation lower than 0.8‰ and 0.1‰ for deuterium and oxygen isotopes, respectively, and normalized to the Vienna Standard Mean Ocean Water (VSMOW) scale.
