A bipolar comparison of deep ice cores from Antarctica (Dome Fuji) and Greenland (GRIP) (scientific paper)
Oxgen isotope ratio and chemistry profiles were compared to find the corresponding interstadials during the Wisconsin Ice Age between the GRIP (Greenland) and Dome Fuji (Antarctica) deep ice core data for the past one hundred and sixty thousand years. Eight interstadials in GRIPδ18O profile were fou...
