Accumulation rates, isotopic and molecular data of terrestrial carbon in sediments of the Laptev Sea continental margin

This dataset contains isotopic (¹³C and ¹⁴C) and molecular biomarker data (lignin phenols, n-alkanes, n-alkanoic acids) of organic carbon in surface...

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...
