Collaborative Research: East Antarctic Outlet Glacier Contributions to the Ross Sea from Chronology of Detrital Grains

Lead PI: Sidney Rasbury Hemming

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

December 2010 - November 2013
Project Type: Research

DESCRIPTION: This project will add to existing data of provenance tracers of East and West Antarctica by adding U/Pb of detrital zircons, U-Th/He subsets, and Ar-Ar of detrital hornblende, mica, and feldspars from till from nunataks at major glacier outlets and beneath three West Antarctic ice streams.

OUTCOMES: Four batches of samples have been analyzed. Most work has been in a supporting role.
