Stable water isotope composition of precipitation from O'Higgins Station, Antarctica, 2008-2009

Oxygen and deuterium isotope analysis of daily precipitation samples collected at O'Higgins Station ( 63°19'15''S, 57°53'55''W), Antarctic Peninsula, during the years 2008 and 2009. Isotope analysis were carried out at the facilities of the Alfred Wegener Institute, Helmholtz centre for polar and marine research in Potsdam, Germany. The samples were analyzed by a MAT Delta S mass spectrometer with two gas equilibration unit. Daily meteorological data for each day was retrieved from the NOAA - Global Surface Summary of the Day (GSOD).
