Description
Summary:The dataset contains compound-specific δ13C and Δ14C isotopic composition of alkanoic acids from permafrost soils and river and fjord sediments the Bayelva catchment and Kongsfjord. These were analyzed in order to determine permafrost OC turnover timescales in the Bayelva catchment, assess export mechanisms along the flow path, and characterize the spatial dispersal and reburial of permafrost OC in Kongsfjord sediments. The sampling strategy was designed to obtain an export transect sample set covering the permafrost soil-river-ocean system. Samples were taken during several land- and ship-based campaigns. In 2007, soil samples from the Bayelva River catchment were collected from the thawed active layer in the northern foreland of the East Brøgger glacier. Leirhaugen (LH) is adjacent to the main stem of the Bayelva River (Boike et al., 2008) and permafrost ground temperatures have been monitored at this site since 1998 (Boike et al., 2018; Roth and Boike, 2001). Additional soil profiles in the catchment were ...
