Fig. 4: Estimated carbon stock in bulk sediments and organic matter (OM) fractions.
From: Stabilization of mineral-associated organic carbon in Pleistocene permafrost

The different organic carbon (OC) pools are mineral-associated OM (MAOM<6.3µm in gray), free particulate OM (fPOM in green) and occluded particulate OM (oPOM<20µm in orange) in Yedoma deposits and thermokarst sediments. The OC pools and uncertainties (with the standard deviation shown as error bars) were estimated based on published OC stocks (and its uncertainty estimates based on observational OC variability) in late Pleistocene permafrost2 (shown as red bars), which is further described in the Methods.
