Webrecognized circumpolar permafrost peat OC pool by 50%. It is further stated that previous integrated studies of the permafrost OC pool (Tarnocai et al., 2009; Hugelius et al., 2013a, b) have failed to account for these deposits because of biases in the Northern Circumpolar Soil Carbon Database (NCSCD). They argue that the field site data of ...
