Ice Core Depth-Age Relation for Vostok (delD) and Dome Fuji (del18O) Records Based on the Devils Hole Paleotemperature Chronology, USGS Open File Report 02-266

This report presents the data for the Vostok - Devils Hole chronology, termed
V-DH chronology, for the Antarctic Vostok ice core record. This depth - age
relation is based on a join between the Vostok deuterium profile (delD) and the
stable oxygen isotope ratio (del18O) record of paleotemperature from a calcitic
core at Devils Hole, Nevada, using the algorithm developed by Landwehr and
Winograd (2001). Both the control points defining the V-DH chronology and the
numeric values for the chronology are given. In addition, a plausible
chronology for a deformed bottom portion of the Vostok core developed with this
algorithm is presented. Landwehr and Winograd (2001) demonstrated the broader
utility of their algorithm by applying it to another appropriate Antarctic
paleotemperature record, the Antarctic Dome Fuji ice core del18O record.
Control points for this chronology are also presented in this report but deemed
preliminary because, to date, investigators have published only the visual
trace and not the numeric values for the Dome Fuji del18O record. The total
uncertainty that can be associated with the assigned ages is also given.
