Bulk organic carbon and biomarker data for the marine sediment core SWERUS-L2-4-PC1, Chukchi Sea, Arctic Ocean

This dataset was created to reconstruct the historical remobilization of permafrost carbon from the Beringian landmass to the Chukchi Sea. We analyzed carbon...

Bulk organic carbon, isotopes and terrigenous biomarkers for the marine sediment core SWERUS-L2-31-PC1

This dataset contains biochemical data analyzed in the sediment core SWERUS-L2-31-PC1, an archive spanning over the past 27,000 years recovered from the...

Concentrations of carbon, nitrogen, lignin and lipid biomarkers in subsea permafrost of the inner Laptev Sea

This dataset includes organic carbon and nitrogen content, ¹³C content of organic carbon, as well as concentrations of lignin phenols, n-alkanes, n-alkanoic...

Isotope data (Δ¹⁴C, δ¹³C and δD) for dissolved methane at the Outer Eurasian Arctic Shelf

Isotope data for dissolved methane determined in samples collected from vertical and bottom-water horizontal casts in the outer Laptev Sea. The data was...

Lithology and thermal data from subsea permafrost drillcores of the SE Laptev Sea
