An oxygen-isotope climatic record from the Devon Island ice cap, Arctic Canada

Isotope measurements on two adjacent cores through the Devon Island ice cap provide a well-dated climatic record for the past 5000 yr. Fluctuations in annual values include much ‘noise’, and ice flow over a rough bed produces distortions in the lowest 5% of core which covers roughly 120,000 yr. Comp...

Description
Summary:Isotope measurements on two adjacent cores through the Devon Island ice cap provide a well-dated climatic record for the past 5000 yr. Fluctuations in annual values include much ‘noise’, and ice flow over a rough bed produces distortions in the lowest 5% of core which covers roughly 120,000 yr. Comparison with the Camp Century, Greenland, record helps to separate climatic changes from changes in ice thickness or flow pattern.
