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. ABSTRACT SUPPLIED BY ORIGINATOR: A nearly continuous record of 10Be (half-life of 1.5x10e6 years) concentrations is reported in the Greenland Ice Sheet Project 2 (GISP2) ice core for the time period between 3288 and 40,055 years B.P. The resolution is between 20 and 50 years in the Holocene. During the Pleistocene, sampling was coarser, with the resolution ranging between 50 and 200 years. Both concentrations and fluxes are reported. Concentrations of 10Be are observed to correlate strongly with d18O and more weakly with snow accumulation rates. Beryllium 10 fluxes show less dependence than do concentrations on climate-related parameters. A good correlation exists between D14C and 10Be for centennial scale variations, which are most likely due to heliomagnetic modulation of the 10Be production rate in the atmosphere. There is no evidence of a long-term geomagnetic effect on the 10Be flux at GISP2. The interpretation of the record depends strongly on the model one uses to infer atmospheric 10Be concentrations from the measured concentrations in snow.
