Thermal state of permafrost and active layer in Central Asia during the international polar year

Permafrost and Periglacial Processes (2010)

Lin Zhao Qingbai Wu S. S. Marchenko Anarmaa Sharkhuu

Abstract Permafrost in Central Asian is present in the Qinghai–Tibet Plateau in China, the Tien Shan Mountain regions in China, Kazakhstan and Kyrgyzstan, the Pamirs in Tajikistan, and in Mongolia. Monitoring of the ground thermal regime in these regions over the past several decades has shown that the permafrost has been undergoing significant changes caused by climate warming and increasing human activities. During the International Polar Year, measured mean annual ground temperature (MAGT) at a depth of 6 m ranged from −3.2°C to 0.2°C on the Qinghai–Tibet Plateau and the active‐layer thickness (ALT) varied between 105 and 322 cm at different sites. Ground temperatures at the bottom of the active layer (TTOP) warmed on average by 0.06°C yr −1 over the past decade. In Mongolia, MAGT at 10–15 m depth increased by up to 0.02–0.03°C yr −1 in the Hovsgol Mountain region, but by 0.01–0.02°C yr −1 in the Hangai and Hentei Mountain regions. The increase in permafrost temperatures in the northern Tien Shan from 1974 to 2009 ranged from 0.3°C to 0.6°C. At present measured permafrost temperatures vary from −0.5°C to −0.1°C. The ALT increased from 3.2 to 4 m in the 1970s to a maximum of 5.2 m between 1995 and 2009. Copyright © 2010 John Wiley & Sons, Ltd.

Plant response to climate change varies with topography, interactions with neighbors, and ecotype

Ecology (2012)

Pierre Liancourt Laura A. Spence Daniel S. Song Ariuntsetseg Lkhagva Anarmaa Sharkhuu

Predicting the future of any given species represents an unprecedented challenge in light of the many environmental and biological factors that affect organismal performance and that also interact with drivers of global change. In a three‐year experiment set in the Mongolian steppe, we examined the response of the common grass Festuca lenensis to manipulated temperature and water while controlling for topographic variation, plant–plant interactions, and ecotypic differentiation. Plant survival and growth responses to a warmer, drier climate varied within the landscape. Response to simulated increased precipitation occurred only in the absence of neighbors, demonstrating that plant–plant interactions can supersede the effects of climate change. F. lenensis also showed evidence of local adaptation in populations that were only 300 m apart. Individuals from the steep and dry upper slope showed a higher stress/drought tolerance, whereas those from the more productive lower slope showed a higher biomass production and a greater ability to cope with competition. Moreover, the response of this species to increased precipitation was ecotype specific, with water addition benefiting only the least stress‐tolerant ecotype from the lower slope origin. This multifaceted approach illustrates the importance of placing climate change experiments within a realistic ecological and evolutionary framework. Existing sources of variation impacting plant performance may buffer or obscure climate change effects.

Spatial distribution of ground surface temperatures and active layer depths in the Hövsgöl area, northern Mongolia

Permafrost and Periglacial Processes (2006)

Eva Solbjørg Flo Heggem Bernd Etzelmüller S. Anarmaa Anarmaa Sharkhuu Clyde E. Goulden

Abstract Near‐surface temperature variations in different topographic settings were obtained from miniature temperature data‐loggers at 17 locations over a 2‐year period in the Lake Hövsgöl area in northern Mongolia. These measurements were used to analyse the influence of vegetation, solar radiation, surface wetness and snow cover on the ground thermal regime. An empirical modelling approach was applied in order to estimate the spatial distribution of ground surface temperatures, the presence of permafrost and the depth of the active layer. Our study shows that spatial interpolation of ground surface temperature parameters, mainly known from previous research in the Arctic, can be feasible in the arid mountain environments of Central Asia.

Occurrence of frost heaving in the Selenge River Basin, Mongolia

Permafrost and Periglacial Processes (1999)

Anarmaa Sharkhuu

This paper describes frost heaving in the Selenge River Basin in central Mongolia. Spatial information has been compiled according to predominant composition of the ground, soil moisture content and water level, permafrost distribution and temperature, and the depth of seasonal freezing/thawing of the ground. This allows the creation of a permafrost-engineering geology map to predict the occurrence and intensity of frost heave. Copyright © 1999 John Wiley & Sons, Ltd. Le présent article décrit le soulèvement par le gel dans le bassin de la rivière Silenge en Mongolie centrale. Une cartographie a été réalisée qui rassemble: 1) la composition principale du sol, 2) le contenu en eau et le niveau de l'eau dans le sol, 3) la distribution du pergélisol et la température, 4) la profondeur du gel saisonnier dans le sol. Cette carte présente un intérêt appliqué pour l'ingénieur en ce qu'elle prédit la distribution et l'importance du soulèvement par le gel. Copyright © 1999 John Wiley & Sons, Ltd.
