Concentrations of methane, sulfate and lipid biomarkers and carbon isotope compositions in the sediments from the outer Laptev Sea

The dataset contains the concentrations of methane, sulfate and microbial lipid biomarkers, and the carbon isotope composition of lipids in the sediment collected from the SWERUS-C3 expedition in 2014. The core sediment samples were from stations 13, 14 and 23 in the outer Laptev Sea. The field investigation reveals it is a methane seep area.
