Record #118818:

Changes in tropospheric methane between 1841 and 1978 from a high accumulation-rate Antarctic ice core / D.M. Etheridge, G.I. Pearman, P.J. Fraser.

Title: Changes in tropospheric methane between 1841 and 1978 from a high accumulation-rate Antarctic ice core / D.M. Etheridge, G.I. Pearman, P.J. Fraser.
Author(s): Etheridge, D. M.
Pearman, G. I.
Fraser, P. J.
Date: 1992.
In: Tellus. (1992.), Vol. 44B(4) (1992)
Abstract: Investigation of core, DE08, from Law Dome, which has extremely fine air--age resolution created by high rate of snow accumulation that encloses air into bubbles over short time span. Possible to reconstruct detailed record of changes in concentration of CH₄ in Antarctic troposphere from about 1841 to when direct atmospheric measurements began in 1978. Comparison of DE08 record and direct atmospheric measurements imply that CH₄ concentration is not significantly modified when enclosed in ice nor when extracted and measured. CH₄ growth rate increased since pre-industrial times, except for 1920-45 when it apparently stabilized.
