  • ABSTRACT: A high-resolution deuterium profile is now available along the entire European Project for Ice Coring in Antarctica Dome C ice core, extending this climate record back to marine isotope stage 20.2, ~800,000 years ago. Experiments performed with an atmospheric general circulation model including water isotopes support its temperature interpretation. We assessed the general correspondence between Dansgaard-Oeschger events and their smoothed Antarctic counterparts for this Dome C record, which reveals the presence of such features with similar amplitudes during previous glacial periods. We suggest that the interplay between obliquity and precession accounts for the variable intensity of interglacial periods in ice core records.
  • GEOGRAPHIC REGION: Antarctica
  • PERIOD OF RECORD: 803 KYrBP - present
  • DESCRIPTION: High-resolution (55cm.) deuterium (dDice) profile from the EPICA Dome C Ice Core, Antarctica (75� 06' S, 123� 21' E), with an optimal accuracy of � 0.5 � (1 sigma), from the surface down to 3259.7 m.
  • DATA: EPICA Dome C bag deuterium data (LSCE, analytical accuracy of 0.5 per mille)
  • Temperature estimated after correction for sea-water isotopic composition (Bintanja et al, 2005) and for ice sheet elevation (Parrenin et al, 2007) on EDC3 age scale (Parrenin et al, 2007)

Uploader notes:
To graph this data (and to meet Microsoft Excel's need for regularly-spaced x-axis values), uploader RCraig09 took data ranging from 10,000 to 20,000 years ago, and mapped each datapoint to the nearest 20-year interval. This mapping expanded 348 (approx) raw temperature data points to 500 regular time intervals, with each resulting time therefore being within 10 years of the original raw datapoint (10/10,000 yields graphing precision to within 0.1%). The resulting temperature data series actually used to make this graph, and their five-interval (100-year) moving average data series, are provided in the expandable text below.

The same dataset, averaged within each millennium to form series of 800 data points, was used to form 800,000-year chart in the top panel of File:800,000-, 2,000-, 139-year global average temperature.png.

This geology 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 “20191021 Temperature from 20,000 to 10,000 years ago - recovery from ice age.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
