We assume that nutrient availability is a major limiting factor of vegetation growth in the Lena Delta besides the general climate characteristics such as low temperature and short growing seasons. We assessed relevant plant communities with projective coverage estimation and biomass harvesting at 27 vegetation plots and sampled soil pits and shallow permafrost cores at 33 sites in the central Lena Delta in August 2018 during the Russian-German Lena 2018 expedition. For upscaling vegetation cover and in-situ biomass estimates we use a medium resolution satellite data based land cover classification. We applied a supervised random forest classification to a cloudfree Sentinel-2 acquisition from August 2018 using the visible, near infrared and shortwave infrared spectral bands after surface water and sandbank masking with a threshold. We targeted the classification towards classes usable for upscaling of biomass and moisture regimes (Fig. 1). Prevailing vegetation types on Holocene and Pleistocene terraces are polygonal tundra complexes and moist to wet sedge and moss-dominated complexes characterized by high wetness and high C/N ratio in the subsoil below the moss layer. Terrain temporarily stabilized following active disturbance is frequently characterized by high vegetation biomass, eg tall shrub communities on floodplains, at the rim of thermokarst basins, and in thermoerosion valleys linked to drier soils and low C/N ratio indicating higher nutrient availability. This study improves our understanding of nutrient availability in Siberian permafrost soils.
