Bulk organic carbon and biomarker data for the marine sediment core SWERUS-L2-4-PC1, Chukchi Sea, Arctic Ocean
Jannik Martens, Örjan Gustafsson
This dataset was created to reconstruct the historical remobilization of permafrost carbon from the Beringian landmass to the Chukchi Sea. We analyzed carbon isotopes (δ¹³C, Δ¹⁴C) and terrestrial biomarkers (lignin phenols) to quantify and characterize the source and terrestrial OC that was transported to the Chukchi seabed between 13,000–11,000 cal yr BP and 3,650 cal yr BP until today. We also performed quantitative apportionments to partition OC source fractions using carbon isotopes and to reconstruct permafrost carbon fluxes.

Data description
The dataset contains OC parameters (TOC, δ¹³C-OC, Δ¹⁴C-OC, OC flux, age in cal yr BP), quantitative data on terrestrial biomarkers (i.e. lignin phenols), mixing model output of fractions of permafrost and marine OC and ¹⁴C-dated foraminifera from the sediment core SWERUS-L2-4-PC1. File type: xlsx.
