A chronology for the TALDICE ice core from the Ross Sea sector of East Antarctica has recently been presented based on methane synchronization with Greenland and the EDC ice cores and d18Oice synchronization with EDC in the bottom part (TALDICE-1). Using new high-resolution methane data obtained with a continuous flow analysis technique, we present a refined age scale for the age interval from 55-112 thousand years (ka) before present, where TALDICE is synchronized with EDC. New and more precise tie points reduce the uncertainties of the age scale from up to 1900 yr in TALDICE-1 to below 1100 yr over most of the refined interval and shift the Talos Dome dating to significantly younger ages during the onset of Marine Isotope Stage 3. Thus, discussions of climate dynamics at sub-millennial time scales are now possible back to 110 ka, in particular during the inception of the last ice age. Calcium data of EDC and TALDICE are compared to show the impact of the refinement to the synchronization of the two ice cores not only for the gas but also for the ice age scale. #------------------ # Funding_Agency # Funding_Agency_Name: Swiss National Science Foundation # Grant: #------------------ # Funding_Agency # Funding_Agency_Name: Prince Albert II of Monaco Foundation # Grant: #------------------ # Site_Information # Site_Name: TALDICE ice core # Location: Antarctica # Country: # Northernmost_Latitude: -72.8167 # Southernmost_Latitude: -72.8167 # Easternmost_Longitude: 159.1833 # Westernmost_Longitude: 159.1833 # Elevation: 2319 m #------------------ # Data_Collection # Collection_Name: TALDICE2011CH4MIS3 # Earliest_Year: 110522 # Most_Recent_Year: 53612 # Time_Unit: Cal.
