English: Extension of File:Epica-vostok-grip-140kyr.png to include GRIP data.
Note that the GRIP and NGRIP en:Dansgaard-Oeschger events should be co-incident; but the timescales are not absolutely referenced. so they appear not to be. Note also that the NGRIP data is regular in time but the GRIP data in depth, hence the apparent greater variability of GRIP in the current interglacial is not real. The greater warmth of NGRIP than GRIP in the current interglacial, but roughly equal warmth in the glacial, is probably real. After 110 kyr the GRIP and NGRIP cores clearly differ: the NGRIP core is reliable, the GRIP core is unreliable due to ice folding near the base. |
