Stable oxygen isotope profile of the B23_2012 firn core, annual means


Stable oxygen isotopes (δ18O) were measured on discrete samples using Cavity Ring-Down spectroscopy with an L2120-i and L2130-i by Picarro Instruments. The δ18O concentration with depth is provided with a precision of better than 0.1 per mil. Using raw, un-calibrated dielectrical profiling (DEP) data from the field (NEEM Set-up), volcanic tie points were derived. Together with the smoothed density data and the isotopic composition the record was dated by layer counting. The annual mean values of δ18O were obtained based on this dating.
