Summary
Description Ice-core-isotope.png |
Deutsch:
Vergleich zwischen Temperatur-Proxies aus Eisbohrkernen der Antarktis und Grönland der letzten 140,000 Jahre. Während die Antarktis-Bohrkerne Delta
2
H verwenden, wurde bei den Grönland Bohrkernen Delta
18
O 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
18
O, while Antarctic ice cores use delta
2
H. 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.
