Such studies are especially relevant due to the climate change observed in this region. The paper propose a hybrid model that combines wavelet transformation of the original data and an artificial neural network with a long chain of short-term memory (LSTM) elements to predict changes in the surface methane concentration in the Arctic latitudes. The methane concentration time series via a discrete wavelet transform was decomposed into four components — one approximating and three detailing ones. These components were used to train the LSTM network. The forecast was calculated as the sum of forecasts for each of the components. Three predictive models were built. In the first, the LSTM network was trained in a non-linear autoregressive mode. The second one was a combination of discrete wavelet transform with LSTM neural network. An additional model based on a non-linear autoregressive neural network (NAR) was also used for comparison. The work is based on data from environmental monitoring of greenhouse gases on Bely Island, Yamalo-Nenets Autonomous Area of Russia. The initial data for building the proposed model were obtained within July-August 2017. The accuracy of the forecast was assessed using several indicators. The hybrid model based on LSTM showed the best accuracy.","PeriodicalId":502389,"journal":{"name":"Arctic: Ecology and Economy","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139346107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to remote sensing data, at the bottom of thermokarst lakes, rivers and coastal zones of the Kara Sea, more than 4.5 thousand zones of powerful gas blowouts with the formation of craters (pockmark) were found. There are reasons to believe that powerful gas emissions mainly come from shallow deposits with ultrahigh (superlithostatic) pressures. For the first time, large mud volcanic uplifts with pronounced craters have been found at the bottom of the Arctic thermokarst lakes. Based on the monitoring of the ice situation and the water environment on the basis of retrospective satellite images on lakes Otkrytie, Labvarto and Yambuto, the presence of periodic emissions of formation fluids, including gas, is shown. Based on the combination of a number of features, the discovered objects can be classified as active mud volcanoes with a high level of probability. The results of the studies allow us to state that mud volcanism is widespread in the Circum-Arctic megaregion.","PeriodicalId":502389,"journal":{"name":"Arctic: Ecology and Economy","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139346964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Nature Park is characterized by high recreational potential as well as environmental significance. 18 species of plants and animals listed in the Red Data Book of the Murmansk Region, as well as five ones listed in the Red Data Book of the Russian Federation are recorded within the boundaries of the Natural Park. There are natural-territorial complexes of special aesthetic value here: the valley of the Teriberka River, the coast of the Barents Sea with a rugged coastline, beaches and sea terraces formed by large rounded boulders, Batareisky Waterfall, rocky hills and areas of shrub tundra, interspersed with small lakes, sheer cliffs with colonies sea birds, a number of historical and archaeological sites. Currently, the landscapes of lower reaches of the Teriberka River are experiencing a strong human impact. An important feature of the territory is easy transport accessibility for tourists. At present, the uncontrolled tourist flow is the most significant agent of the territory transformation, as a result of which landscapes with high aesthetic qualities begin to degrade. With the creation of a natural park, the intensity and coverage of human disturbances of landscapes will be reduced, and the existing aesthetic potential of landscapes will be used more efficiently. Land use planning has been developed in order to establish a differentiated regime of special protection. The nature protection areas are intended to preserve the environment in its natural state, and the recreational zone is intended to ensure and implement recreational activities and nature-educational tourism. In order to preserve the landscape and architectural unity of the village and the natural park, regulation has been introduced for the construction of new and reconstructed buildings in accordance with the historical environment.","PeriodicalId":502389,"journal":{"name":"Arctic: Ecology and Economy","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139343580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal energy source for the district option is a coal-fired boiler house; the one for the individual option is automated pellet boilers. The boiler house receives coal according to a complex multi-link scheme, whereas pellets are produced on site. The district heating option involves laying heat networks throughout the village because currently it has none. The individual heating option suggests the construction of a pellet production plant. Environmental indicators are calculated emissions of pollutants and carbon dioxide emissions from fuel combustion. Pollutants include solids, sulfur dioxide, nitrogen oxides, and carbon monoxide. Along with environmental indicators, the authors consider the conditions for ensuring energy security in various heating options. The research findings show the advantage of the individual heating option based on automated pellet boilers for environmental indicators. The risks for this option are assessed from the standpoint of threats to the energy security of the settlement in comparison with the district heating option. The factors considered as threats include those affecting the reliability and survivability of process technologies, an increase in the thermal energy cost, and the availability of fuel and energy resources. The main limitation for the option of individual heating in the Arctic territories, which is based on locally produced wood pellets, is the lack of reasonable reserves of available wood in wood-cutting areas near the settlement.","PeriodicalId":502389,"journal":{"name":"Arctic: Ecology and Economy","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139345377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the article is to assess the effectiveness of the Arctic residents’ institution as a tool for the development of the Arctic territories and the reduction of their polarization. The study assesses the investment attractiveness of the regions of the Arctic zone of the Russian Federation using econometric methods and cluster analysis, taking into account statistical indicators and expert assessments in five areas for 2010—2021. Also, using similar methods and according to financial statements the authors analyze the economic efficiency and sustainability of 295 economic entities that received the status of Arctic resident in 2020—2021. The level of investment attractiveness of the regions they compare with the efficiency and sustainability of the residents functioning on its territory. They have revealed that the institution of Arctic residents, although contributing to the development of the Arctic regions, leads to further polarization of their indicators.

The features of the ionic composition of ultra-fresh waters of the Arctic rivers have been considered, the class, group and type of river waters have been established according to the classification of O. A. Alekin. The chemical composition of the ultra-fresh rivers of the Russian Arctic zone is characterized by great diversity. These rivers vary from the most simple bicarbonate-calcium waters of the second type to sulfate or hydrocarbon-sulfate waters of a complex cationic composition. For the estuarine sections of the Virma, Kolos-Yoki, Teriberka and Ura Rivers variability manifests itself in a simplification of the chemical composition. For the Pravaya Khetta, Sede-Yakha and Nadym Rivers, changes in the ratios between cations and anions have been revealed. For the Indigirka, Yana Rivers and its tributaries, changes have been noted only in the anionic composition. It is shown that it is for these rivers that the metamorphization of river waters is possible. Most of the river sections with a high probability of metamorphization of the ionic composition of water are confined to the West Siberian part of the Russian Arctic zone. This is due to a higher anthropogenic load and a high degree of development of this area. For these sections of the rivers, the revealed metamorphization is of a technogenic nature. The metamorphization process of ultra-fresh river waters in the direction of changing the hydrocarbonate class to the sulfate or chloride class can cause the appearance of hydrochemical anomalies in the content of the main ions.","PeriodicalId":502389,"journal":{"name":"Arctic: Ecology and Economy","volume":"111 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139346333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
