“…The average SOC concentration on the steep, forest-covered slopes of Bucharama Valley reached 5.2%, slightly more than the values of 4.6% on the mountain tundra plots on the western edges of the plateau 36 and 4.7% in a low-Arctic site (64°N) featuring relatively flat topography and sparse spruce forest cover but less than the values of 7.6% and 11.7% in sites at considerably lower (58°N) and higher (75°N) latitudes 60 . The average 2.15% SOC concentration on gentler slopes of Malyj Orokan was noticeably lower than that in all the other localities but was comparable to the value of 2.6% in the gently undulating Siberian Yedoma sediments with a SOL thickness of 30–50 cm 61 , 62 .…”

Efforts to estimate the impact of climate change-induced forest expansion on soil carbon stocks in cold regions are hindered by the lack of soil organic carbon (SOC) concentration data. The presented study addressed the information gap by establishing SOC concentration and its variability in two catchments inside the vast, remote, and rugged Putorana Plateau. Additionally, it explored interrelationships among the terrain relief, vegetation cover, surface organic layer, SOC and its mineral association on the northernmost boundary of the forest-tundra biome traversing the northwestern part of the Central Siberian Tableland. Soil samples were taken from the active layer on the slope base, middle, and below the upper forest boundary. Subsequently, they were analyzed for SOC concentration by dry combustion. Multiple linear regression identified associations between slope angle and surface organic layer thickness and between SOC concentration and surface organic layer thickness, clay content, and dithionite-extracted Al. Clay content and surface organic layer thickness explained 68% of the overall SOC concentration variability. When used with data produced by remote sensing-based multipurpose large-scale mapping of selected biophysical factors, the acquired regression equations could aid the estimation of SOC across the rugged terrain of the Siberian Traps.

The Norilsk Mining and Metallurgical Plant for the production of nickel, platinum and palladium is the main pollutant in the Arctic. The nature and degree of its impact on natural ecosystems over a long, since 1935, history of its work, varied along with changes in production volumes under different forms of ownership, and the response of ecosystems developed against the background of climate warming. Based on a review of studies carried out in the region, periods with different ratios of technogenic and natural factors in the dynamics of ecosystems are distinguished, which also differ in the methods of their study. In the second half of the 20th century, in the 1970s–1990s, an increase in sulfur dioxide emissions into the atmosphere led to the drying up of larch forests at a distance of up to 120 km southeast of the plant, recorded by aerial photography and forest pathological studies, as well as by a map of the ecosystems state, compiled by Landsat imagery and MSU field research. At the end of the 20th century, after the collapse of the USSR, an interruption in the operation of the plant, which passed from state to private ownership, led to a decrease in production rates and emissions into the atmosphere. This was combined with climate warming, which intensified in the Arctic regions. Complex expeditionary work of Siberian scientists in the first decades of the XXI century, including geochemical and dendrochronological studies, fixed the boundaries of zones of varying degrees of disturbance of ecosystems, but at the same time showed that along with the continuing degradation of vegetation, partial restoration of ecosystems is taking place. At the end of the second decade of the XXI century, Russian and American scientists, based on the processing of large volumes of remote sensing data, based on a multi-temporal analysis of vegetation indices, discovered the “greening” of low habitats in the Norilsk region as a result of secondary succession with a complex interaction of technogenic and natural, primarily climatic, factors.
