Anthropogenic-Driven Alterations in Black Carbon Sequestration and the Structure in a Deep Plateau Lake

Abstract: The continuous flux of organic carbon (OC) from terrestrial ecosystems into inland water is an important component of the global carbon cycle. The buried OC pool in inland water sediments is considerable, and black carbon (BC) is a significant contributor to this OC pool because of the continuous growth in BC emissions. Therefore, determining the effect of BC on total OC burial and variations in the structure of BC during the burial process will contribute significantly to our understanding of lacustrine carbo… Show more

“…The equation used for the constant rate of 210 Pb supply (CRS) model in the Supporting Information (SI; eq ) is wrong, it should be Where A (0) is the residual of unsupported 210 Pb in the entire record (from the sediment surface to the equilibrium depth of total 210 Pb with supported 210 Pb), or the 210 Pb inventory, A is the residual of unsupported 210 Pb in the sediments of age t or greater, and λ is the 210 Pb decay constant. As all the cores do not reach their equilibrium depths, the A (0) should not be only “the total content of 210 Pb in the sediment core” . If a core does not reach the equilibrium depth, our practice in the UCL Environmental Radiometric Facility is to estimate the equilibrium depth in the sediments by following the 210 Pb exponential decay trend in the bottom of the core, and then derive the missed unsupported 210 Pb beyond the core base for the residual calculations.…”
