Soil organic carbon (SOC) stored in northern peatlands and permafrost-affected soils are key components in the global carbon cycle. This dataset provides SOC storage and organic layer depth for 47 soil pedons located in the Stordalen catchement. Stordalen is a sub-arctic mountainous peatland environment in the discontinuous permafrost zone in Abisko, northern Sweden. The data is provided as total SOC storage (SOCTot) including wetland pedons processed to a reference depth of 1.5 m and non-wetland pedons processed to a reference depth of 1 m. If the pedon did not reach that depth it was extrapolated based on a trend in the pedon or similar pedons or set to zero if the lithic contact was reached. Other extracted depth intervals are the SOC stored in the organic surface layer (SOCOL),in the permafrost layer (SOCPF), the SOC stored for the top 30 cm (SOC0to30) and the SOC for the top 100 cm (SOC0to100). SOC values are in kg C m-2 . The depth of the organic layer (OLdepth) in cm is also provided.The location of each pedon is provided as XY coordinates projected in WGS 84 / UTM zone 33N (EPSG: 32633). Altitude is provided from a GPS reading.More information on how the soil data was collected and processed can be found in the linked article (Open Access).
