Depths are at variable intervals and are not continuous. Investigators have provided 36Cl/Cl ratios. Calculation of 36Cl concentration (atom/g) requires the Cl concentration in the same sample, which is not available. All 10Be results have more than 20% uncertainty due to accelerator mass spectrometry (AMS) calibration issues and the uncertainty in the volume of melting water; these require large corrections.EnglishAGDCFTP136 KBPDFThis data set includes a record of cosmogenic radionuclide concentrations in the Siple Dome A ice core collected as part of the West Antarctic ice core program. The investigators measured profiles of both <sup>10</sup>Be (half-life = 1.5x10<sup>6</sup> years) and <sup>36</sup>Cl (half-life = 3.0x10<sup>5</sup> years) in the entire ice core, which spans the time period from the present to about 100,000 years before present. These data are being used for perfecting the ice core chronology, deducing the history of solar activity, deducing the history of variations in the geomagnetic field, and studying the possible role of solar variations on climate.
