[{"name":"wild-2022-subsea-permafrost-1","title":"Concentrations of carbon, nitrogen, lignin and lipid biomarkers in subsea permafrost of the inner Laptev Sea","summary":"This dataset includes organic carbon and nitrogen content, \u00b9\u00b3C content of organic carbon, as well as concentrations of lignin phenols, n-alkanes, n-alkanoic acids, n-alkanols and selected sterols in subsea permafrost samples from the inner Laptev Sea. Samples from five cores are included, and span a range of depths from 1 to 50 m, with highest resolution around the ice-bonded permafrost table at the time of sampling.\r\n\r\nThe data allow an assessment of carbon storage, organic matter sources and degradation history in subsea permafrost \u2014 one of the least constrained compartments of the global carbon cycle.\r\n\r\nCores were taken between 2012 and 2014 in the Buor Khaya Bay.","citations":"Wild B, Shakhova N, Dudarev O, Ruban A, Kosmach D, Tumskoy V, Tesi T, Grimm H, Nybom I, Matsubara F, Alexanderson H, Jakobsson M, Mazurov A, Semiletov I, Gustafsson \u00d6 (2022) Organic matter composition and greenhouse gas production of thawing subsea permafrost in the Laptev Sea.
