Biomarker and bulk organic carbon data for surface sediments across the Laptev Sea
Lisa Bröder, Örjan Gustafsson
This dataset was compiled for a study that aims to assess the fate of terrestrial organic carbon 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 (δ¹³C, Δ¹⁴C) in surface sediments from a Laptev Sea transect spanning more than 800 km from the Lena River mouth (< 10 m water depth) across the shelf to the slope and rise (2000-3000 m water depth).

Data description
All data are stored in one xlsx file. The two tabs refer to the two tables in the publication: first sampling locations, water depths, bulk organic carbon properties and mineralogy, second biomarker concentrations and ratios (solvent-extractable lipids and CuO oxidation products).
Project
Sediments were collected during the International Siberian Shelf Study 2008 and the Swedish-Russian-US Investigation of Carbon-Climate-Cryosphere Interactions in the East Siberian Arctic Ocean 2014
