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.
