Cross-shelf transport time and degradation rates for terrestrial organic matter in the Laptev Sea
Örjan Gustafsson, Lisa Bröder
This dataset contains compound-specific radiocarbon dates for long-chain fatty acids (specific terrestrial biomarkers) along a 600-km transect from the Lena River delta, across the Laptev Sea shelf to the slope, along with associated bulk carbon isotopes and biomarker loadings. From these data, transport times and degradation rates have been derived.

Project
The sediment samples used to develop this dataset were collected during the Swedish-Russian-US Investigation of Carbon-Climate-Cryosphere Interactions in the East Siberian Arctic Ocean (SWERUS-C3) 2014 and the International Siberian Shelf Study 2008 (ISSS-08) expeditions, supported by the Knut and Alice Wallenberg Foundation, the Swedish Polar Research Secretariat and the Headquarters of the Far Eastern Branch of the Russian Academy of Sciences. This project was also supported by the Swedish Research Council (VR Contracts No. 621-2007-4631, 621-2013-5297 and 2017-01601), European Research Council (ERC-AdG CC-TOP project #695331 to Ö.G.), the US National Oceanic and Atmospheric Administration (OAR Climate Program Office, NA08OAR4600758/Siberian Shelf Study), the Russian Science Foundation (No. 15-17-20032), the Nordic Council of Ministers and the US National Science Foundation (OPP ARC 0909546; 1023281).
