Atmospheric concentrations of carbon dioxide (CO2) have been derived
from ice cores in Antarctica.
Atmospheric CO2 concentrations for Siple Station (West Antarctica)
were derived from measurements ...
Atmospheric concentrations of CH4 were extracted from the 2,184-m ice core from
Byrd Station (Antarctica) for the period 550 - 51,100 BP in 1967-68 by
the U.S. Cold regions Research and Engineering ...
Ice cores drilled at Siple Station (Antarctica) for 200-m depth were analyzed
for CH4 concentrations for the period 1771-1956. Two different methods were
used for extracting air in the ice core (dry ...
