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...

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

Lithology and thermal data from four drill cores used in a study that documents current rates and mechanisms of subsea permafrost degradation in the East...

Organic carbon data from the Eurasian Arctic Shelf

Percentage of permafrost organic carbon resequestered by iron oxides in the Eurasian Arctic Shelf. Overall, the 15 ± 5% in the Laptev Sea and 6.4 ± 5% in...

Seawater Carbonate System, Ocean Acidification and Related Parameters in the East Siberian Arctic Shelf Seas

This dataset builds on an order of magnitude more observations than reports to date on Ocean Acidification (OA) in the Arctic Ocean; and, for the first time in...

The Circum-Arctic Sediment Carbon Database — CASCADE

The Circum-Arctic Sediment CArbon DatabasE (CASCADE) was established to curate data on concentrations of organic carbon (OC) and total nitrogen (TN), OC...
