From Soil to Ocean: Transfer of terrigenous organic carbon from permafrost soils to the Arctic Ocean

Updated 2008-03-14

In order to estimate the effect of rising global temperatures on organic carbon (OC) stocks in the temperature-sensitivity Arctic environment, our project aims at investigating the transfer of terrestrial OC from permafrost soils to the Arctic Ocean. Detailed compositional analyses of bulk soil and sediments along a transport trajectory combined with compound-specific isotopic (13C and 14C) analysis of selected lipid biomarkers will be used to study alteration processes of organic matter occurring in the soil and its during transport. Sub-goals include to a) identify suitable biomarkers for soil organic carbon in permafrost soils, b) determine residence times of selected biomarkers in permafrost soils, fluvial and marine sediments, and c) quantify carbon transfer from source (soil) to sink (marine sediment) and its timescale.
