A depth-age relation for the Antarctic Vostok ice core links its deuterium profile (delD) to the Devils Hole, Nevada, paleotemperature record (del18O) using a published algorithm. The report also provides a preliminary chronology for the Dome Fuji ice core del18O record. Data was published by the U.S. Geological Survey in Open File Report 02-266.
Use Cases
- Calibrating the Vostok ice core age scale by joining the Vostok delD profile with the Devils Hole del18O record.
- Analyzing the chronology of the deformed bottom portion of the Vostok core using the provided algorithm.
- Evaluating preliminary control points for the Dome Fuji ice core del18O chronology against other Antarctic records.
- Assessing total uncertainty associated with assigned ages in the V-DH chronology for error propagation in climate studies.
Strengths
- Chronology is based on a peer-reviewed algorithm developed by Landwehr and Winograd (2001).
- Report provides both control points and numeric values for the Vostok-Devils Hole (V-DH) chronology.
- Includes analysis for a second Antarctic ice core record (Dome Fuji del18O).
Limitations
- Dome Fuji chronology is labeled as preliminary due to reliance on a visual trace rather than published numeric values.
- Specific row counts, column details, and sample sizes for the underlying data are not provided in the description.
- Temporal coverage and geographic scope beyond the core sites are not explicitly defined.
