Arctic climate change has already resulted in amplified and accelerated regional warming, or the amplification. Satellite observations have captured this phenomenon its development sufficient spatial details. As such, these been—and still are—indispensable for monitoring of amplification remote inhospitable region, which is sparsely covered with ground observations. This study synthesizes key contributions satellite into an understanding characterization The reveals that satellites were able...

Climate change represents a global challenge that impacts the environment, traditional lifestyle and health of Indigenous Peoples in Arctic zone Western Siberia threatens their food security. Reindeer are an important source for this population since reindeer herding products used as nutrition effective preventive means remedies adapting to cold geomagnetic activity High North. Longer off-season periods, high summer winter temperatures, melting ice, forest tundra fires have significant...

Abstract. The rapidly warming Arctic undergoes transitions that can influence global carbon balance. One of the key processes is shift towards vegetation types with higher biomass underlining a stronger sink. predicted by bioclimatic models based on abiotic climatic factors, but it not always confirmed observations. Recent studies highlight role disturbances in shift. Here we use high-resolution remote sensing to study process transition from tundra forest and its connection wildfires 20 000...

Wildfires in permafrost areas, including smoldering fires (e.g., “zombie fires”), have increasingly become a concern the Arctic and subarctic. Their detection is difficult requires ground truthing. Local Indigenous knowledge are becoming useful sources of information that could guide future research wildfire management. This paper focuses on peatland Siberian subarctic taiga linked to local communities their infrastructure. It presents results field studies Evenki old-settler Tokma Khanda...

The most common hazardous geological processes affecting the right-of-way of trans-Sakhalin pipeline system (within Sakhalin-2 Project), primarily in Makarovsky District, are considered, and prerequisites for their development listed. A database these was created results visual inspection route oil spills were described. adequacy monitoring reclamation activities along study area analyzed. It is found that sections exposed to geologic considered during design construction facility subject...

On the basis of a detailed comparison boundaries disturbed areas with land allotments for infrastructure facilities, share exceeding permissible mechanical impact on soil and vegetation cover representative sample oil gas fields located in natural conditions northern taiga was estimated. It found that total withdrawal averages 7.2 %, while median limits regulated relative to area is 9.3 %. The retrospective analysis dynamics within carried out, which showed 9-11 years industrial development...

In this paper, the subject of study is dangerous exogenous processes as one main factors emergency situations on pipelines. The territories Western Yamal (Bovanenkovo – Ukhta gas pipeline), Southern Yakutia (East Siberia Pacific Ocean oil and Sakhalin Island (Sakhalin-2 pipelines) were selected model sites. High-resolution satellite images WorldView-2/3 digital terrain models AW3D30 ArcticDEM are used source data. All available decryption methods in work, including use artificial neural...

The paper is aimed at assessing the associations between road networks geography and dynamics of wildfire events in East Siberian boreal forest. We examined relationship function roads, their use, management ignition, propagation, termination during catastrophic fire season 2016 Irkutsk Region Russia. Document analysis interviews were utilized to identify main forest users infrastructure functional types examine practices. combined community observations satellite remotely sensed data assess...

Abstract. Persistent warm urban temperature anomalies – heat islands (UHIs) significantly enhance already amplified climate warming in the Arctic. Vulnerability of infrastructure Arctic cities urges a region-wide study UHI intensity and its attribution to drivers. This presents an overview surface atmospheric UHIs all circum-Arctic settlements (118 total) with population larger than 3000 inhabitants. The (SUHI) is obtained from land (LST) data products Moderate Resolution Imaging...

Governments around the world took unprecedented measures, such as social distancing and minimization of public/industrial activity, in response to COVID-19 pandemic 2020. This provided a unique chance assess relationships between key air pollutant emissions track reductions these various countries during lockdown. study considers atmospheric pollution 78 largest Russian cities (with populations over 250,000) March–June 2019–2021. is first for Russia.

For the first time in polar riverbed, a pingo (a blow-up) was detected, which destroyed on June 28, 2017 by emission, self-ignition and gas explosion with formation of crater.Prompt expedition to Seyakha crater (C11), formed Myudriyakha riverbed Yamal Peninsula, analysis remote sensing data allowed reconstruct geodynamical processes growth, caused pressure, active thermoabrasive (speed up 1,47-1,6 meters per day), destroying walls.Assuming great remoteness deep wells from site determined...

Abstract Urban landscape combines built-up areas with strongly altered natural (green and blue) other open spaces. Voluminous literature examines urban socio-environmental interactions in tropical temperate cities, whereas high-latitude cities are rarely considered. Here, we create a historical perspective on green (vegetation) blue (water) spaces sub-Arctic city of Nadym Russia. Our study explores novel way to combine quantitative information from satellite imagery biometric studies...

Trees in Arctic cities perform not only important provisional and regulating ecosystem services, but also bring predominantly settler population closer to the visual images household standards of their home southern regions. However, maintenance green infrastructure has specific difficulties associated with harsh climatic environmental conditions. This paper focuses on state dynamics vegetation city Nadym, Russia, a particular focus native introduced trees as main service providers an...

The sedimentary record of aeolian deposits and geomorphic features the landforms Northern Eurasia contain important information that allows us to better understand climate environments Late Glacial Early Holocene periods. At same time, degree scientific knowledge about timing activity, as well landscapes existed during these periods, differs significantly for different parts this vast territory. Data on sedimentological age estimations phases are practically absent periglacial zone Western...

The paper provides geoecological assessment of natural and urban thermokarst lakes for the town Nadym, typical West Siberian Arctic. Although there is no developed industry in town, we have found that occurs an anthropogenic transformation geochemical composition surface waters comparison with background ones, which manifested increase alkalinity water chronic contamination petroleum products. reasons these changes are littering coastal zones construction debris historical pollution cement...
