have been applied extensively to the quantification of forest carbon stocks and potential stock changes across a range of scales from stand to national levels. The principal objectives of this study are an evaluation of the completeness and robustness of the C-FLOW and CARBINE models for estimating carbon stocks and potential stock changes in the forestry sector at the stand and national levels...

The vast amount of organic carbon (OC) stored in soils of the northern circumpolar permafrost region is a potentially vulnerable component of the global carbon cycle. However, estimates of the quantity, decomposability, and combustibility of OC contained in permafrost-region soils remain highly uncertain, thereby limiting our ability to predict the release of greenhouse gases due to permafrost ...

Crust restoration is increasingly being done but we lack quantitative information on soil improvements. The study aimed to elucidate the dynamics involving soil microbial biomass carbon and soil dissolved organic carbon in the re-vegetation chronosequences of a hillslope land with purple soil in Hengyang, Hunan Province. The soil can cause serious disasters with both soil erosion and seasonal d...

General Comments The discussion paper offers interesting results and a welcome alternative to assessing the soil carbon stocks and changes in Alaska. The equilibrium model approach is particularly helpful since the only other alternative to addressing the question of SOC response to warming seems to be process model outputs (i.e. “ESM’s” in the paper). The map is probably an improvement over ot...
