Thermal regime of moraine cover in the Adygene valley, Kyrgyz Range
Martinásková, Daša ; Engel, Zbyněk (advisor) ; Uxa, Tomáš (referee)
Submitted Bachelor thesis is focused on thermal regime of the morain covering, which is one of the main indicators of the extension in periglacial and glacial zone in the mountain environment. Introductory part is concluded from themed literature and is primarily focused on the characteristics of the thermal regime of sediments and their relationship to the boundaries of the mountain permafrost, position of equilibrium snow line and temperature-based mountain glaciers. The following sections of this work are describing physical and geographic conditions of the valley of Adygine in Kyrgyz Range area (northern Tien-Shan) as well as the methodologhy of the used work The main part of this document is the evaluation of measured temperature in the morain cover in the area of interest. At first from general point of view, then in terms of freeze-thaw characteristics and finally relate these findings to the local conditions of the glaciál environment. According to the measured results, is it clear that there are many factors influencing the soil temperature regime. Among the most fundamental, the most important include air temperature, local circulation conditions, snow cover and local habitat conditions. Knowledge gained from the practical part shows that the measurement localitions are characterized by...

Thermal regime of moraine cover in the Adygene valley, Kyrgyz Range
Martinásková, Daša ; Engel, Zbyněk (advisor) ; Uxa, Tomáš (referee)
The focus of this bachelor thesis is the thermal regime of the morain covering in the valley of river Adygine in Kyrgyz Range area in the northern Tien-Shan. The intention of this thesis is to evaluate the temperature measurements from the glacis zone of the Adygine glacier and to explicate the results with regards to the continuance of recent permanent snow line and permafrost area. In the area of interest, with altitude 3498 to 3659 m, two air temperature sensor and five thermistors with MINIKIN dataloggers were installed. The thermistors measure temperature in 15 and 30 cm depths below the surface of glacial accumulations. The surface layer of morains melts annually for three or five months, mean annuall ground temperature did not drop below -2řC and area of measurements is distinguished with weak freeze-thaw activity. The mean annual air temperature in year 2011 was -4,5 in 3653 m and -6,1řC in 3913 m altitude respectively. The comparsion of measured data with publicated average permafrost temperature data in nearby ranges of Tan-San mountains suggests, that area of interest is located in discontinuous mountain permafrost area. Zero isothermic line is located in approximately 2900m altitude. This is lower than the mountain permafrost level and so the base of glaciál forefront can be denoted as...
