These are preliminary data of cosmogenic radionuclides (10Be and 36Cl) in the
Siple Dome A ice core. 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.

Group: Summary
This 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 10Be
(half-life = 1.5x106 years) and 36Cl (half-life =
3.0x105 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.
Data are distributed as a PDF file and are available via FTP.
