原始语种摘要: Fluvial discharge and coastal erosion of the permafrost-dominated EastSiberian Arctic delivers large quantities of terrigenous organic carbon(Terr-OC) to marine waters. The composition and fate of the remobilizedTerr-OC needs to be better constrained as it impacts the potential for aclimate–carbon feedback. In the present study, the bulk isotope ( δ 13C and Δ14C) and macromolecular (lignin-derived phenols)composition of the cross-shelf exported organic carbon (OC) in differentmarine pools is evaluated. For this purpose, as part of the SWERUS-C3expedition (July–September 2014), sediment organic carbon (SOC) as well aswater column (from surface and near-bottom seawater) dissolved organiccarbon (DOC) and particulate organic carbon (POC) samples were collectedalong the...
