Record #191084:

Peatland exchanges of CO₂ and CH₄: the importance of presence or absence of permafrost / Torben R. Christensen, and 3 others.

Title: Peatland exchanges of CO₂ and CH₄: the importance of presence or absence of permafrost / Torben R. Christensen, and 3 others.
Author(s): Christensen, Torben R.
Date: 2010.
In: PAGES News. (2010.), Vol. 18(1) (2010)
Abstract: Describes how presence of permafrost has dramatic impact on land-atmosphere exchanges of key greenhouse gases, and reports recent research on functioning of ecosystems with and without permafrost. At central Alaskan site, permafrost thawing is accompanied by respiration of previously frozen, ancient organic carbon. In Siberian thaw lakes, methane has been observed forming from recently thawed Pleistocene organic deposits.
