Description:

Abstract:: Melted water was collected from the outside of samples taken for cation and anion analysis. A small aliquot was taken for anion analysis (chloride, nitrate, and sulfate) and the remainder was weakly acidified with HNO3 to yield a final pH of about 2. Be, Cl and Al carriers were then added. The Be (and Al and Cl) were concentrated from the melted ice using ion exchange resins. Be was then eluted from the cation exchange column, precipitated as Be(OH)2 and ignited to BeO for accelerator mass spectrometry (AMS) measurement. The AMS measurements were carried out at the Lawrence Livermore National Laboratory Center for Accelerator Mass Spectrometry (Davis et al., 1990). The 10Be (half-life = 1.5 x 10^6 years) concentration was normalized to an ICN standard (diluted by K. Nishiizumi) after carrier blank and boron background correction.
