The onset of major millennial warming events in Siple Dome preceded major abrupt warmings in Greenland, and the pattern of millennial change at Siple Dome was broadly similar, though not identical, to that previously observed for the Byrd ice core (also in West Antarctica). The addition of Siple Dome to the database of well-dated Antarctic paleoclimate records supports the case for a coherent regional pattern of millennial-scale climate change in Antarctica during much of the last ice age and glacial-interglacial transition. STUDY NOTES: Siple Dome Ice Core, West Antarctica ice core hydrogen isotope (deuterium, dD) data, with age model correlated to the GISP2 ice core time scale using methane and d18O. Data are from 515 to 919 meters depth, corresponding to 9 to 57 KYrBP. NCDC-Paleoclimatology https://www.ncdc.noaa.gov/data-access/paleoclimatology-data - Bauer Bruce Investigator : Brook, E.J.
