A Study of Atmospheric Dust in the WAIS Divide Ice Core Based on Sr-Nd-Pb-He Isotopes

Lead PI: Michael Kaplan , Dr. Steven Lloyd Goldstein , Dr. Gisela Winckler , Aloys Bory (Co-PI); Leopoldo Pena Gonzalez (Co-PI)

Unit Affiliation: Geochemistry, Lamont-Doherty Earth Observatory (LDEO)

June 2011 - July 2017
Inactive
Antarctica
Project Type: Research

DESCRIPTION: The project will attempt to determine if source dust in the Western and Eastern Antarctic Ice Sheets are different as GCMs imply by using isotope-based provenance data from ice cores. Cores will be tested for Sr-Nd isotope signatures and integrated with existing high-resolution data.

OUTCOMES: Protocols have been developed for the LDEO ultra-clean laboratory to process samples, the first of which have been completed.
