Other courses held were "Processes and American Partners) Geodynamic Risks" at the Universidad Nacional de Cuyo, Mendoza as part of the Master program in One of the outstanding tasks of the Geocryology Unit territorial planning. Another course on Geocryology, of Mendoza (D. Trombotto, J. Hernández) were the “Permafrost and Ice in Caves” was held during a thermogeomorphological monitoring campaigns at the workshop on speleology in Malargüe. Peteroa volcano (35º15´S and 70º35´W) in a joint research project with the Comisión Nacional de There have been joint initiatives of Chile and Argentina Energía Atómica (P. Penas, Buenos Aires) and the under the international project: "Dinámica de glaciares International Center for Earth Sciences (A. Ramires, rocosos en el Chile Semiárido" (Dynamics of rock Malargüe). glaciers in Semiarid Chile) in cooperation with the University of Waterloo, Ontario, Canada, the Daytime as well as nighttime flights with a Cessna 180 Universidad Católica de Chile, Santiago and the for four passengers with thermo-cameras a AGEMA Geocryology Unit IANIGLA, CONICET Mendoza, TVH 550 or a sophisticated FLIR P660 made it Argentina. In the framework of a project funded by the possible to identify hot (active craters with fumaroles) Dirección General de Aguas (DGA), F.

Within the 2010 (FOTO) were detected. As part of this project in same project, P. Iribarren (DGA), A. Brenning, X. the region of the Peteroa Volcano and the upper basin Bodin and G. Azócar set up two new permafrost of the Malargüe river, Pablo Grizas has began his monitoring sites (Tapado and Llano de la Liebre, near doctoral thesis on periglacial hydrology under the the Agua Negra pass, border with Argentina), including direction of Dario Trombotto. sub-surface temperature measurements, active layer temperature measurements with material and help from D. Trombotto, L. Ruiz (Geocryology, IANIGLA) and J. Hernández and GPS-based survey of surface displacements. Those sites and the equipment are part of the DGA’s glacier monitoring network. Other active monitoring sites in order to create a bigger Chilean geocryological network are Laguna Negra and La Parva in the Central Andes of Santiago. They are attended mainly by the specialists mentioned above. Dario Trombotto Liaudat ([email protected]) 2 Austria Eruption of the Peteroa Volcano, September 20, 2010 Permafrost research in Austria was intensified (Photograph provided by Dario Trombotto). substantially during the last years. As a consequence of this development, a first official meeting of permafrost scientists from Austria and South Tyrol was In 2010 Argentina had significant national and held in 2010. This Permafrost Workshop was international transfer activities. In March there was a organized on 14-15 October 2010 in Obergurgl (Tyrol, scientific exchange program with the University of Austria) to bring together most scientists working on Salzburg, Austria. In August Trombotto took part in the alpine permafrost in Austria and South Tyrol, and to International Short Course on Permafrost Engineeging present and discuss current research activities on as a lecturer in Santiago de Chile. The same course alpine permafrost. In total, about 50 people from 17 was then given in San Juan, Argentina. This special different research institutions participated in this course on Geocryology was organized by BGC successful workshop. The first day of the meeting was Engineering Inc. (L. Arenson, S. Pastore) from the focusing on research exchange and oral and poster 2 / 32 presentations. On the second day the participants visited the rock glacier Äusseres Hochebenkar (or The University of Innsbruck group of K. Krainer in Outer Hochebenkar) thereby discussion different cooperation with the Vienna University of Technology permafrost related issues directly in the field (Figure (E. Brückl, H. Hausmann), the Central Institute for below). This rock glacier is well known to the scientific Meteorology and Geodynamics in Salzburg/ZAMG community because of its remarkably long record of Salzburg (C. Riedl, A. Klee, M. Staudinger) and the geodetic and photogrammetric measurements starting Geological Survey of Austria (A. Römer) continued in the 1930s. The workshop was mainly organised by workingontheproject Permafrost in Austria .The goal K. Krainer (Uni. Innsbruck) supported by H. of the Krainer-group in the two projects Permafrost in Hausmannn and E. Brückl (both TU Vienna). One of Austria and permAfrost (WP5000) is the study of the the main results of the workshop was the foundation of impact of changes in the thermal regime of alpine an informal “Austrian Permafrost Working Group”. The permafrost on melting processes, discharge patterns two main objectives of this group are, first, to improve and water chemistry at test sites in the Ötztal Alps, coordination and cooperation of future research Samnaungruppe, Stubai Alps and Verwallgruppe by activities on alpine permafrost in Austria and South using a combination of geological, geomorphological, Tyrol and, second, to select “key sites” for a long-term hydrogeological, geophysical, geochemical, monitoring in the Austrian Alps. Since this meeting, the meteorological and climatological methods. Within the national committee of IPA-Austria consists of A. project PermaNET ,three ice-cores were drilled at two Kellerer-Pirklbauer (Uni. Graz, TU Graz), G.K. Lieb rock glaciers (Lazaun, Weissbrunn) in September (Uni. Graz), K. Krainer (Uni. Innsbruck), L. Schrott 2010. The ice-cores are studied regarding ice content, (Uni. Salzburg) and H. Hausmann (TU Vienna). chemical composition of the ice (anions, cations, heavy metals), palynology, age and stable isotopes. Furthermore, work on a rock glacier inventory of the Federal Province of Tyrol was continued. Geophysical investigations (E. Brückl, H. Hausmann) at the study area Krummgampental, Kaunertal (Ötztal Alps) were continued as reported last year. The University of Innsbruck group of J. Stötter continued to carry out permafrost research within the PermaNET and C4AUSTRIA projects.Furthermore,the project permAfrost (WP6000) wasinitiatedfocusingon the monitoring of thawing of mountain permafrost with multi-temporal airborne laser scanning (ALS) data. Participants of the first Austrian Permafrost Workshop Botanists from the University of Innsbruck (B. with scientists from Austria and South Tyrol, held on Erschbamer, R. Grassmair) started to investigate the 14-15 October 2010 in Obergurgl, Tyrol, Austria. The plant colonization in relation to grain size of the participants visited the famous rock glacier Äusseres substrate, soil temperature, pH and flow velocity at the Hochebenkar (Outer Hochebenkar) where geodetic rock glacier Äusseres Hochebenkar. Ecologists from and photogrammetric measurements starting already the University of Innsbruck (K. Koinig, R. Psenner, E. in the 1930s. (Photograph provided by Andreas Ilyashuk, R. Lackner, G. Köck) worked on the impact Kellerer-Pirklbauer). of melting permafrost on water quality and aquatic organisms in alpine lakes. Impacts are ranging from In 2010, the new national project permAfrost–Austrian rapid increases in conductivity to toxic levels in metal Permafrost Research Initiative – was launched. The concentrations that can exceed drinking water project consortium consists of permafrost researchers standards by more than an order of magnitude. A new from the University of Innsbruck (K. Krainer, H. project investigates the impact of permafrost meltwater Stötter), Graz University of Technology (A. on aquatic organisms. In addition, they will study Kellerer-Pirklbauer, M. Avian, V. Kaufmann), sediment cores in order to investigate whether the University of Leoben (E. Niesner), University of current increase in metals in permafrost melt water is Salzburg (J.-C. Otto), and Vienna University of unprecedented, or whether comparable increases in Technology (E. Brückl, H. Hausmann) and is metal concentrations occurred during warmer periods coordinated by the Austrian Academy of Sciences (A. in the past. Borsdorf,M.Monreal). permAfrost is a first step establishing a nationwide permafrost monitoring ZAMG Salzburg continued to work on PermaNET program in Austria with a running period of three years. and Permafrost in Austria at the study area Hoher 3 / 32 Sonnblick (3105 m), Hohe Tauern Range. Ground temperature is monitored continuously at three The group of permafrost researcher in the Federal boreholes (each 20 m) in the summit region (see province of Styria consisted in 2010 of people from the earlier reports). At borehole 1, continuous data are University of Graz (A. Kellerer-Pirklbauer, G.K. Lieb, available since end of 2007. Technical problems at O. Sass, M. Rode), Graz University of Technology (M. boreholes 2 and 3 were solved and since August 2010 Avian, V. Kaufmann, A.
