Abstract:
A record of Pb and Ba concentrations and Pb isotopic compositions are presented for the EPICA Dome C ice core covering the two oldest glacial-interglacial cycles (~572 to 801 kyr ago) characterized by lukewarm interglacials in the European Project for Ice Coring in Antarctica Dome C ice core, provides evidence for dust provenance in central East Antarctic ice prior to the Mid-Brunhes Event (MBE), ~430 kyr ago.

Event(s):
EDC (EPICA Dome C) * Latitude: -75.100000 * Longitude: 123.350000 * Date/Time Start: 1993-01-01T00:00:00 * Date/Time End: 2004-12-31T00:00:00 * Elevation: 3233.0 m * Recovery: 3300 m * Location: Dome C, Antarctica * Campaign: Dome C * Method/Device: Ice drill (ICEDRILL) * Comment: Drill site is 56 km from the site of a previous Dome C core that provided records extending into the last glacial period, and 560 km from the site of the Vostok cores. The completion of the Dome C core was delayed when the first drilling became stuck at 788 m in 1999 (EDC96).
