We analyzed carbon isotopes (\u03b4\u00b9\u00b3C, \u0394\u00b9\u2074C) and terrestrial biomarkers (lignin phenols) to quantify and characterize the source and terrestrial OC that was transported to the Chukchi seabed between 13,000\u201311,000 cal yr BP and 3,650 cal yr BP until today. We also performed quantitative apportionments to partition OC source fractions using carbon isotopes and to reconstruct permafrost carbon fluxes.
