Summary

Abstract:
Accelerator Mass Spectrometry (AMS) measurements of cosmogenic isotopes were made from erratic and bedrock samples collected in the Ellsworth Mountains, 2005-2006. Pressed AMS targets were analysed at SUERC (Scottish Universities Environmental Research Centre) to yield exposure ages.

Keywords:
AMS, Ellsworth Mountains, Wedell Sea Embayment, cosmogenic isotope analysis, ice sheet thinning
