This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “Ice-core-isotope.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
Deutsch: Vergleich zwischen Temperatur-Proxies aus Eisbohrkernen der Antarktis und Grönland der letzten 140,000 Jahre. Während die Antarktis-Bohrkerne Delta 2H verwenden, wurde bei den Grönland Bohrkernen Delta 18O verwendet. Auffallend sind hier die de:Dansgaard-Oeschger-Ereignisse in den Grönland-Eisbohrkernen im Zeitraum von 20,000 bis 110,000 BP. Diese Ereignisse sind in den entsprechenden Kernen aus der Antarktis kaum zu erkennen
English: Comparison of temperature proxies for ice cores from Antarctica and Greenland for 140,000 years. Greenland ice cores use delta 18O, while Antarctic ice cores use delta 2H. Note the en:Dansgaard-Oeschger events in the Greenland ice core between 20,000 and 110,000 years ago, which barely register (if at all) in the corresponding Antarctic record.
GRIP and NGRIP data is on ss09sea timescale, Vostok uses GT4, and EPICA uses EDC2.
