  • High-Mountain Permafrost in the Austrian Alps (Europe)
    HIGH-MOUNTAIN PERMAFROST IN THE AUSTRIAN ALPS (EUROPE) Gerhard Karl Lieb Institute of Geography University of Graz Heinrichstrasse 36 A-8010 Graz e-mail: [email protected] Abstract Permafrost research in the Austrian Alps (Eastern Alps) is based on a variety of methods, including at large scales, the measurement of the temperature of springs and of the base of winter snow cover, and at small scales, mainly an inventory of some 1450 rock glaciers. Taking all the information available into consideration, the lower limit of discontinuous permafrost is situated near 2500 m in most of the Austrian Alps. These results can be used for modelling the permafrost distribution within a geographical information system. Detailed investi- gations were carried out in the Doesen Valley (Hohe Tauern range) using additional methods, including several geophysical soundings. In this way, realistic estimates of certain permafrost characteristics and the volume of a large active rock glacier (some 15x106m3) were possible. This rock glacier has been chosen as a monitoring site to observe the effects of past and future climatic change.

  • Late Wisconsin Climate Inferences from Rock Glaciers in South-Central
    LateWisconsin climatic inlerences from rock glaciers in south-centraland west-central New Mexico andeast-central Arizona byJohn W. Blagbrough, P0 Box8063, Albuquerque, NewMexico 87198 Abstract Inactive rock glaciersof late Wisconsin age occur at seven sites in south-central and west-central New Mexico and in east-centralArizona. They are at the base of steep talus in the heads of canyons and ravines and have surfacefeatures indicating they are ice-cemented (permafrost) forms that moved by the flow of interstitial ice. The rock glaciersindicate zones of alpine permafrost with lower levels that rise from approximately 2,400m in the east region to 2,950 m in the west. Within the zones the mean annual temperaturewas below freezing, and the climatewas marked by much diurnal freezing and thawing resulting in the production of large volumes of talus in favorableterrain. The snow cover was thin and of short duration, which fa- vored ground freezing and cryofraction. The rock glaciers in the east region occur near the late Wisconsin 0'C air isotherm and implv that the mean annual temperature was depressedapproximately 7 to 8'C during a periglacial episodein the late Wisconsin.A dry continental climate with a seasonaldistribution of precipitation similar to that of the present probably prevailed, and timberline former timberlines. may have been depresseda minimum of 1,240m. The rise in elevation of the rock glaciersfrom east to west acrossthe region is attributed to greater snowfall in west-centralNew Mexico and east-centralArizona, which reducedthe inten- sity and depth of ground freezing near the late Wisconsin 0"C air isotherm.

  • Inventory and Distribution of Rock Glaciers in Northeastern Yakutia
    land Article Inventory and Distribution of Rock Glaciers in Northeastern Yakutia Vasylii Lytkin Melnikov Permafrost Institute, Siberian Branch of the Russian Academy of Sciences, Yakutsk 677010, Russia; [email protected] Received: 2 September 2020; Accepted: 8 October 2020; Published: 10 October 2020 Abstract: Rock glaciers are common forms of relief of the periglacial belt of many mountain structures in the world. They are potential sources of water in arid and semi-arid regions, and therefore their analysis is important in assessing water reserves. Mountain structures in the north-east of Yakutia have optimal conditions for the formation of rock glaciers, but they have not yet been studied in this regard. In this article, for the first time, we present a detailed list of rock glaciers in this region. Based on geoinformation mapping using remote sensing data and field studies within the Chersky, Verkhoyansk, Momsky and Suntar-Khayata ranges, 4503 rock glaciers with a total area of 224.6 km2 were discovered. They are located within absolute altitudes, from 503 to 2496 m. Their average minimum altitude was at 1456 m above sea level, and the maximum at 1527 m. Most of these formations are located on the sides of the trough valleys, and form extended sloping types of rock glaciers. An assessment of the exposure of the slopes where the rock glaciers are located showed that most of the rock glaciers are facing north and south. Keywords: rock glacier; permafrost; inventory; northeastern Yakutia; remote sensing 1. Introduction The geography of distribution of rock glaciers is quite extensive. They are found in many mountainous regions of Europe, North and South America and Asia, including some circumpolar regions [1–18].

  • Aklisuktuk (Growing Fast) Pingo, Tuktoyaktuk Peninsula, Northwest Territories, Canada J
    ARCTIC VOL, 34, NO. 3 (SEPTEMBER 1981). P. 270-273 Aklisuktuk (Growing Fast) Pingo, Tuktoyaktuk Peninsula, Northwest Territories, Canada J. ROSS MACKAY’ ABSTRACT. Field surveys have been carried out for the 1972 to 1979 period in order to study the growth of Aklisuktuk (Growing Fast) Pingo. The field surveys show that the top of the pingo was slowly subsiding dsring the seven-year survey period, possibly from a slow downslope glacier-like creep of the ice-rich overburden and ice core. The name “Aklisuktuk” probably dates back at least 200 years. The rapid growth which attracted attention was from accumulation of water in a large sub-pingo water lens. Key words: Aklisuktuk Pingo, sub-pingo water lens, pingo subsidence RÉSUMÉ: Des lev& sur le champs ont kt6 effectues entre1972 et 1979en vue d’ktudier le pingoAklisuktuk (“grandi vite”).

Active rock glaciers contain permafrost and creep slowly downslope often forming typical flow structures with ridges and furrows related to compressional forces. Rock glaciers are widespread landforms in the Austrian Alps (c. 4600). Despite the high number of rock gla- ciers in Austria, only few of them have been studied in detail in the past. One of the best studied ones is the 950 m long Dösen Rock Glacier located in the Hohe Tauern Range. This rock glacier has been investigated since 1993 using a whole suite of field- based and remote sensing-based methods. Research focused on permafrost conditions and distribution, surface kinematics, inter- nal structure and possible age of the landform. Results indicate significant ground surface warming of the rock glacier body du- ring the period 2007-2015 accompanied by a general acceleration of the rock glacier surface flow velocity (max.

The potential turnover of frozen ground from a carbon sink to a carbon source, eroding coastlines, landslides, amplified surface deformation and endangerment of human infrastructure are some of the consequences connected with thawing permafrost. Satellite remote sensing is hereby a powerful tool to identify and monitor these features and processes on a spatially explicit, cheap, operational, long-term basis and up to circum-Arctic scale. By filtering after a selection of relevant keywords, a total of 325 articles from 30 international journals published during the last two decades were analyzed based on study location, spatio- temporal resolution of applied remote sensing data, platform, sensor combination and studied environmental focus for a comprehensive overview of past achievements, current efforts, together with future challenges and opportunities. The temporal development of publication frequency, utilized platforms/sensors and the addressed environmental topic is thereby highlighted.
