Lead Isotopic Constraints on the Provenance of Antarctic Dust and Relevant Atmospheric Circulation Patterns Prior to the Mid-Brunhes Event (~430 Kyr Ago)

Autor: Changhee Han, Laurie J. Burn, Paul Vallelonga, Sanghee Lee, Soon Do Hur, Sungmin Hong, Claude F. Boutron

A lead (Pb) isotopic record, covering the two oldest glacial-interglacial cycles (~572 to 801 kyr ago), from the European Project for Ice Coring in Antarctica Dome C ice core provides isotopic evidence for the provenance of dust in deep Antarctic ice

The date of the definitive start to the Anthropocene is still under debate, and although a lot of progress has been made, currently available data is not precise enough to define the start of the human-dominated geological epoch. We know that during

[1] Iron deposition influences primary production and oceanic sequestration of atmospheric carbon dioxide (CO2). Iron has two oxidation states, Fe(II) and Fe(III), with Fe(II) being more soluble and available for oceanic phytoplankton uptake. The pas
