Petrogenic OC used for biosynthesis of sediment core HE519_2-3

Based on the CSRD obtained by AMS the contribution of fossil OC (F14C=0; [%]) used for bacterial membrane lipid synthesis (IPL-FA) was calculated using an isotope mass balance. For the estimation two endmembers were used: 1) Fossil carbon (F14C=0) – OC derived from the local bedrock 2) Recently synt...

Description
Summary:Based on the CSRD obtained by AMS the contribution of fossil OC (F14C=0; [%]) used for bacterial membrane lipid synthesis (IPL-FA) was calculated using an isotope mass balance. For the estimation two endmembers were used: 1) Fossil carbon (F14C=0) – OC derived from the local bedrock 2) Recently synthesized carbon (F14C~1) – OC derived from primary production in the water column. Detailed F14C-values were taken from surface DIC age model, depending on the year of sediment deposition (based on Pb+Cs age model).
