Summary

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 of air bubbles in a 200-m ice core
drilled during the summer 1983-1984. The core was drilled by the Polar
Ice Coring Office in Nebraska and the Physics ... Institute at the
University of Bern (Switzerland). The ice was dated to an accuracy of
about +/- 2 years down to a depth of 144 meters. Atmospheric CO2
trends were obtained for the period 1734-1983 from the core and show
an increase in CO2 of 22.5% from 1750 to 1984. The Siple Station data
was provided by A. Neftel, H. Friedli, E. Moor, H. Lotscher,
H. Oeschger, U. Siegenthaler, and B. Stauffer (Physics Institute,
University of Bern, Switzerland).
