The measured oxygen isotopic data for the "DSS" (Dome Summit South) Law Dome ice core.

These data were collected from the drilling site at Dome Summit South (DSS) on Law Dome in East Antarctica. The DSS site is on Law Dome, a prominent ice dome located about 120 km from Casey Station. The site receives a high rate of snow accumulation which helps create a very detailed climate record.The water isotope (d18O) record for the "DSS" (Dome Summit South) Law Dome ice core. Law Dome water isotope record spans 90kyr and this data was computed from average isotopes with 20 year averaging. The d18O measurements were completed using Isotope Ratio Mass Spectrometers. Drilling of the DSS ice core commenced in 1987/88 Australian Antarctic program season and was completed in 1992/93. The DSS ice core reached a depth 1196m.
