Fate of terrigenous organic matter across the Laptev Sea from the mouth of the Lena River to the deep sea of the Arctic interior by L. Bröder, T. Tesi, J. A. Salvadó, I. P. Semiletov, O. V. Dudarev, Ö. Gustafsson

“…<br><br> This study aims to assess the fate of terrigenous organic carbon (TerrOC) in the Arctic marine environment by exploring how it changes in concentration, composition and degradation status across the wide Laptev Sea shelf. We analyzed a suite of terrestrial biomarkers as well as source-diagnostic bulk carbon isotopes (<i>δ</i>¹³C, Δ¹⁴C) in surface sediments from a Laptev Sea transect spanning more than 800 km from the Lena River mouth (&lt; 10 m water depth) across the shelf to the slope and rise (2000–3000 m water depth). …”
