Interpolated time scale for the ice with GICC05 ages for each bag depth (0.55 m segments) of the EGRIP core in the 13.7 - 1383.8 m depth interval ...
A first chronology for the East GReenland Ice core Project (EGRIP) over the Holocene and last glacial termination has been derived by transferring the annual layer counted Greenland Ice Core Chronology 2005 (GICC05) from the NGRIP core to the EGRIP core using 381 matchpoints of mainly on volcanic ev...
