Historical Methane (CH4) Record from the Siple (Antarctica) Ice Core, in CDIAC,Trends '93
Entry ID: CDIAC_CH4_SIPLE

[ Update this Record ]

Summary
Abstract: 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 extraction and vacuum melt
extraction). CH4 concentrations increased from 0.78 ppmv in 1771 to 1.30 ppmv
in 1955 by dry extraction method and from 0.80 ppmv in 1771 to 1.34 ppmv in
1956 by vacuum melt ... View entire text
