Abstract:
Within the Russian-German research project CARBOPERM the organic matter (OM) in several permafrost cores from Bol'shoy Lyakhovsky Island in NE Siberia was investigated. In the context of the observed global warming the aim was to evaluate the potential of freeze-locked OM from different depositional ages (Eemian to Holocene) to act as a substrate provider for microbial production of greenhouse gases from thawing permafrost. To assess this potential bulk elemental parameters (total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC), total nitrogen (TN), TOC/TN ratios, Hydrogen Index and Oxygen Index data), the concentrations of free (directly extractable part) and bound (after ester cleavage) formate and acetate, the concentration of phospholipid life markers and the concentration of branched and isoprenoid glycerol dialkyl glycerol tetraethers (GDGT) were determined.
