Special Issue "Permafrost Landscape"
A special issue of Land (ISSN 2073-445X).
Deadline for manuscript submissions: 30 June 2020.
Interests: Permafrost landscape; Climate change; Landscape stability; Permafrost monitoring; GIS; Remote sensing
Permafrost landscapes occupy one-fourth of the world's land area. Their current state largely depends on recent climate changes and anthropogenic impacts. Understanding the dynamics and sensitivity of permafrost landscapes, predicting their future development, finding solutions to environmental and land use problems, and developing adaptation strategies to the changing climate and permafrost are critically important today. This Special Issue will present permafrost landscape investigations dealing with theoretical aspects, new research methods, observation data analysis, and predictive modeling.
In this Special Issue, we invite you to submit papers on the following topics:
- Theory and methodology of classification;
- Mapping, remote sensing, and geographical information system (GIS) modeling;
- The current state of landscapes, environmental problems, and land use;
- Assessment of landscape sensitivity to current climate change and anthropogenic impacts;
- Retro-analysis and forecasting; and
- Adaptation to environmental changes.

Abstract: Currently, the issue of the amount of greenhouse gases (in particular methane) released from the permafrost distribution areas is widely discussed. Every year this issue becomes more urgent in connection with the observed active warming process in the Arctic. At the same time, there is an increase in the active layer, degradation of permafrost and the release of additional greenhouse gases. To date, quantitative estimates of the methane content in the rocks of the active layer and the upper part of the permafrost is extremely small. The aim of the work is to determine the methane content in the active layer and the upper horizon of frozen rocks and to estimate the maximum values of methane fluxes into the atmosphere in the dominant landscapes of the typical tundra of Western Siberia. The work was carried out at the key Marre-Sale site, located in a typical tundra zone on the West coast of the Yamal Peninsula. The geological, geocryological structure and landscape structure of the site are well studied. For sampling to determine the content of methane, as well as methane isotopes δ13c(CH4) and D(CH4), pits were made pits and trenches in the active layer and in upper part of the permafrost. Sampling in the studied landscapes was carried out at key points in 2016, 2017, 2018, 2019, which allowed to compare data from different years. In parallel, samples were taken to study the particle size distribution, humidity, density, and organic carbon content. Work was carried out to determine the values of methane emissions in ventilated chambers. The analysis of the obtained data shows that the methane content in the upper horizons of rocks in different landscapes of the typical tundra varies very widely. In the active layer of drained and poorly moist tundra methane content is negligible (5-300 ppmv). In watered and swampy landscapes of polygonal tundra, swamps, U-shaped bottoms of dens, ravines, the methane content is much higher (up to 1500-5000 ppmv). Analysis of the isotopic composition of methane from the rocks of the active layer shows that it is characterized by a heavier isotopic composition in carbon compared to methane in permafrost. Methane in all samples is of biogenic origin. To illustrate the spatial distribution methane in landscapes of the typical tundra, a schematic map of the "methane content in the active layer and the upper horizon of frozen rocks of dominant landscapes" of the study area was compiled.
Title: Influence of Climate Change on the Thermal Condition of Yakutia’s Permafrost Landscapes (Chabyda Station)

Abstract: This paper presents the results of 35-38 years of observations conducted at the Chabyda station to monitor the thermal state of permafrost landscapes under current climatic warming. The analysis of long-term records from weather stations in the region has revealed one of the highest increasing trends in mean annual air temperature in northern Russia. Quantitative relationships in the long-term variability of ground thermal parameters, such as ground temperature at the bottom of the active layer and seasonal thaw depth, have been established. The ground temperature dynamics within the depth of zero annual amplitude indicates that both warm and cold permafrost are thermally stable. Short-term variability of the snow accumulation regime is the main factor controlling the thermal state of the ground in permafrost landscapes. The depth of seasonal thaw is characterized by low interannual variability and exhibits little response to climate warming, with no statistically significant increasing or decreasing trend. The results of the ground thermal monitoring can be extended to similar landscapes in the region, providing a reliable basis for predicting heat transfer in natural, undisturbed landscapes.
