Sediment properties, carbon dioxide and oxygen fluxes from Siberian Arctic Ocean sediments collected in 2020

Lewis Sauerland, Nicholas Ray, Jannik Martens, Tommaso Tesi, Oleg Dudarev, Örjan Gustafsson, Igor Semiletov, Birgit Wild

This dataset contains observational data on sediment properties and gas fluxes (carbon dioxide and oxygen) for 16 surface sediment samples from the Laptev Sea, Kara Sea and East Siberian Sea sampled during the ISSS-2020 expedition.

This dataset entails a) sediment properties including: lignin phenol and n-alkane biomarkers, carbon and nitrogen concentrations, stable and radioactive carbon isotope composition of sediment organic carbon, isotopic carbon source apportionment fractions and grain size distribution, b) aerobic carbon dioxide and oxygen fluxes and sediment oxygen uptake and c) data on statistical analyses.

This data was generated with the purpose of investigating the influence of sediment properties on sediment carbon dioxide emissions and oxygen consumption.
