Cosmogenic nuclide dating of two stacked ice masses: Ong Valley, Antarctica

Abstract > 10 Be, 21 Ne, and 26 Al in quartz in the englacial and supraglacial debris and compare the model predictions to measured nuclide concentrations in order to further constrain the age. Large downcore variation in measured cosmogenic nuclide concentrations suggests that the englacial debris is sourced both from subglacially derived material and recycled paleo-surface debris that has experienced surface exposure prior to entrainment. We find that the upper section of the ice core is 2.95 +/- +/- - 1 +/- - 1 2 were higher than present. These ancient ice masses represent new opportunities for gathering ancient climate information.
