Dry sedimentation rate (gC m-2yr-1) and OC content (%) in each layer was used for the OC
burial calculation. Average OC burial ranged from 699 to 1,979 gC m-2yr-1. Since OC content for the entire lake is more or less 2%, the OC accumulation is completely dominated by the high sedimentation rates in Lake Wohlen. Accordingly, there is a strong relationship between the sedimentation rate and OC burial (R2=0.94).Total mineralisation was calculated from the sum of CO2 production and CH4 production. The lowest value was found 59 gC m-2yr-1 and the highest was found 208 gC m-2yr-1. The OC burial efficiency ranged from 85 to 92% (mean, 89).
