<b>Carbon Release</b>

We performed an in-depth examination of the Late Pleistocene coevolution of organic carbon remobilisation and ice sheet expansion, by adding more high-resolution records of organic carbon burial on the East Siberia-Alaska continental margin. The main objective was the quantitative estimation of the extent of organic carbon remobilisation using a reconstruction approach to determine the total organic carbon (TOC) fluxes to the seafloor. The goal was to determine the contribution of dissolved inorganic carbon (DIC) released from remobilised organic carbon degradation to the Arctic Ocean and northern Nordic Seas carbon sink capacity, and thus to atmospheric CO₂ levels.
