The DSS1617_Glacial_isotopic_composition is the measured oxygen and deuterium isotopic data for the ‘DSS’ (Dome Summit South) ice core (DSS1617) collected during the Antarctic 16/17 season. The glacial isotopic composition was measured on melted ice samples using a Picarro water isotope analyser (L2130-i). A key output for this project will be the time series of water isotopes (d18O and dD), which provides a temperature proxy record. In addition, deuterium excess can be computed, to explore moisture source conditions, including its applicability as a source temperature. In addition, the time series of water isotopes (d18O and dD) will also contribute to the multi proxy approach for the chronological control of the recently collected DSS ice cores.
