„Wenn ich es nicht tue, dann macht’s ein anderer“ – Subjektwerdungen und Verantwortung - Geiselhart, Klaus; Häberer, Tobias (Geographica Helvetica, 2019)
Poststructuralist theory focuses largely on describing how and why subjects reproduce the social conditions they have internalised. This is a deconstruction of the central idea of the Enlightenment, the human capacity for autonomous action. At the same time, however, it also denies all individuals any responsibility and ultimately leads criticism into a crisis. Pragmatist philosophy offers the possibility of determining the role of the mind in processes of becoming a subject without abandoning the achievements of the poststructuralist concept of subjectification. The concept of transaction describes how actors constitute each other as subjects within social situations. The relationships that arise through such processes depend, among other things, on the personalities of those people involved. Accordingly, it is possible to identify the responsibility of individuals to govern their social relations and personality development. Since these aspects can only be determined in localised individual cases, this offers a particularly suitable starting point for geographical criti

Wet season precipitation during the past century reconstructed from tree-rings of a tropical dry forest in Southern Ecuador - Pucha Cofrep, Darwin; Peters, Thorsten; Bräuning, Achim (Global and Planetary Change, 2015)
This study investigates the dendroclimatic potential of tree species in a tropical dry forest in southern Ecuador. From 10 selected tree species, Bursera graveolens and Maclura tinctoria exhibited distinct annual and cross-datable tree-rings. It was possible to synchronize individual tree-ring series and to establish two tree-ring chronologies of 203 and 87 years length, respectively. The characteristic ENSO frequency band is reflected in wavelet power spectra of both chronologies. Both species show a strong correlation between ring width and precipitation of the wet season (January–May). Strong El Niño events (1972, 1983 and 1998) lead to strong growth responses in the tree-ring chronologies, whereas ‘normal’ ENSO events do not trigger long-lasting growth responses. The first ring-width based wet-season precipitation reconstruction for the past 103 years was developed. Statistical and spatial correlation analysis verified the skills of the reconstructed precipitation which captures a great part of the Rainfall Index over the land area of Ecuador and the equatorial Pacific. Furthermore, teleconnections with central Pacific precipitation and SST patterns were found.

When mobile policies drive against the wall. Limits of policy transfer using the example of Business Improvement Districts in Germany - Michel, Boris (Berichte. Geographie und Landeskunde, 2013)
This paper argues that recent debates on policy transfer and mobile policies would benefit by challenging the implicit focus on " successful" cases and instead take failure more seriously - both on an empirical as well as conceptual level. Drawing on a research project on the globalization of Business Improvement Districts, it is argued that the history of Business Improvement Districts in Germany should not be read as a story of successful transfer, as has been done by critical as well as sympathetic scholars and advocates. Business Improvement Districts are far from becoming major agents of urban change - be it agents of neoliberal urbanism and private urban governance or be it agents of urban renewal and civil society. Focusing on successful cases and projects, it is argued, reifies the perspective of those agents that are able to articulate their voices within hegemonic discourses.

WHO guidelines challenged in Botswana: traditional medicine between healing, politics and witchcraft. - Geiselhart, Klaus (Journal of Political Ecology, 2018)
The World Health Organization (WHO) supports integrating traditional health care into national health systems. The reasons why this is not happening in Botswana are manifold, complex and not always rational. Traditional healers demand the right to practice their techniques and organize themselves with an emancipatory political claim, but they are unsuccessful. Based on a political ecology of health perspective combined with assemblage thinking, this article explores discourses and historical lines of development in order to show how Christian morality, the dualism between tradition and modernity and the introduction of a modern public health system are intertwined with belief in witchcraft that clandestinely hampers development.<br

Who Maps Middle Eastern Geographies in the Digital Age? Inequalities in Web 2.0 Cartographies in Israel/Palestine - Glasze, Georg; Bittner, Christian (Media and Mapping Practices in the Middle East and North Africa, 2021)
Cartographic practices have long been the domain of professionalized and centralized actors from governmental or commercial spheres. Inspired by the emergence of mapping practices in the age of Web 2.0, however, new forms of mapping may offer a bottom-up alternative. Indeed, the mapping platforms Wikimapia and especially OpenStreetMap have proven that geographical information and maps can be generated via crowdsourcing by cartographic amateurs. Yet, several studies have excavated powerful exclusion mechanisms in such Web 2.0 cartographies, showing that user-generated geographical content is often produced by privileged demographic groups. This chapter will explore these patterns of exclusion and inclusion in OpenStreetMap and Wikimapia in the examples of the Gaza Strip and Jerusalem. <br

(Why) did Desertec fail? An interim analysis of a large-scale renewable energy infrastructure project from a Social Studies of Technology perspective - Schmitt, Thomas (Local Environment, 2018)
In 2009 the Desertec Industrial Initiative (DII) was founded by several, predominant German enterprises. The objective of DII was to organise the conditions for the realisation of the Desertec idea, which aimed to both (a) supply Europe, in a large-scale manner, with electricity produced in solar power plants in North Africa and the Arabic peninsula and (b) contribute to the self-supply of the Middle East North Africa region (MENA). Protagonists of the desert energy idea saw this megatechnic project as a starting point for a new trans-Mediterranean EU-MENA union, critics in contrast as a neo-colonial project. Disputes over the adequate interpretation and implementation of the Desertec idea broke out from the beginning. In 2014/2015, the media talked of the failure of DII and of the Desertec concept. The majority of the members left DII at the end of 2014. On the other hand, in some MENA countries renewables are playing a crucial role in securing the future of the energy sector. This paper analyses the development of DII and the Desertec idea by using concepts from Social Studies in Technology, and especially by the multi-level perspective approach in Transition Studies. It shows how the interplay of different factors, such as technological developments, entrepreneurial performances and political processes, lead to internal conflicts and the non-realisation – up to now – of related large-scale energy projects. As an important aspect of the paper, different understandings of the future of our energy supply and of North–South relations are presented in detail.<br

Wie wachsen Tropenbäume? Jahrringe als Ausdruck von Klimabedingungen und Lebensform. - Bräuning, Achim; Volland, Franziska; Schnakenburg, Peter (Biologie in Unserer Zeit, 2009)
Das Wachstum tropischer Baumarten hängt von der Saisonalität des lokalen Klimas ab. In Gebieten mit markanter Trockenzeit stellen viele Baumarten die kambiale Aktivität zeitweise ein und bilden Jahrringe. In feuchten Bergregenwäldern wird das Baumwachstum nach kurzen trockeneren Phasen eingestellt. Mit einer Kombination von Zuwachsmessungen und holzanatomischen Analysen kann die Klimasteuerung der Holzbildung entschlüsselt werden. Die intra-annuelle Variabilität der Holzdichte und der Verhältnisse stabiler Isotope erlauben die klimaökologische Interpretation der Signale im Holz.

»Wir müssen als Deutsche und Europäer unsere digitale Souveränität zurückgewinnen!« Historische Rekonstruktion und internationale Kontextualisierung der Diskurse einer »digitalen Souveränität« in Deutschland - Dammann, Finn; Glasze, Georg (Was heißt digitale Souveränität? Diskurse, Praktiken und Voraussetzungen »individueller« und »staatlicher Souveränität« im digitalen Zeitalter, 2022)
Digitale Souveränität« hat sich in den 2010er-und 2020er-Jahren zu dem zentralen Leitmotiv nationaler und internationaler Digitalpolitik entwickelt. Auch in den politisch-öffentlichen Diskursen in Deutschland werden seither vielfach Ansätze einer »digitalen Souveränität« aufgegriffen – und dies in ganz unterschiedlichen gesellschaftlichen Bereichen. Diese Rückbesinnung auf Souveränität über digitale Informations- und Kommunikationssysteme muss zunächst verwundern, war die deutsche Telekommunikationspolitik doch seit den frühen 1990er-Jahren geprägt von Vorstellungen eines »schlanken Staates« und einer Überwindung nationaler Grenzen hin zu einer »globalen Informationsgesellschaft«. Gerade ein Beharren auf Prinzipien staatlich-territorialer Souveränität galt als überholt und wurde vielfach kritisiert. Wie lässt sich vor diesem Hintergrund die Rezeption von »digitaler Souveränität« in den 2010er-Jahren in Deutschland erklären? Zur Beantwortung dieser Fragen rekonstruieren wir in diesem Beitrag ausgehend von der Kommerzialisierung des Internets in den 1990er-Jahren bis in die frühen 2020er-Jahre jene historischen Brüche und (Dis-)Kontinuitäten im digitalpolitischen Diskurs, die zur Konsolidierung einer spezifischen Diskursformation rund um das Schlagwort »digitale Souveränität« in Deutschland beigetragen haben – und situieren diese in den internationalen Kontex

Wood anatomy and vessel characteristics of spiny monkey orange (Strychnos spinosa) in Benin (West Africa) - Avakoudjo, Hospice Gérard Gracias; Gebrekirstos, Aster; Koné, Mamidou Witabouna; Assogbadjo, Achille Ephrem; Bräuning, Achim (Dendrochronologia, 2022)
The response of plant species to varying climate conditions in tropical Africa remains poorly understood but can be assessed using wood anatomical traits. These traits play an important role for the adaptive capacity of a species to environmental stress, since environmental conditions can modify the proportion, size, and morphology of wood anatomical elements. This study reports quantitative data on vessel characteristics of the diffuse porous angiosperm Spiny monkey orange (Strychnos spinosa Lam.) in Benin in tropical West Africa. The vessel-related anatomical traits varied with high amplitude (coefficient of variation CV ˃ 25%) between different sites located in different climate zones. The variability of the traits is higher within one climatic zone than between climatic zones, and even more pronounced within trees. Consequently, the climatic zones have less influence on the studied features than local site conditions. However, the study showed that S. spinosa individuals that have numerous vessels also have a high lumen fraction and total ring area. On the other hand, individuals presenting a high vessel density also display vessels of smaller size. The correlation between vessel number and total ring area on the one hand, and between vessel size and lumen fraction on the other hand are highly significant and positive. In Benin, S. spinosa wood anatomical traits are likely linked to local site factors rather than to regional climatic factors.

"World War II was the best thing that has happened to geography“ Der Beitrag des Zweiten Weltkrieges zu einer neuen Raum- und Kartenpraxis in der Geographie - Michel, Boris (Medien – Krieg – Raum, 2018)

Worldwide version-controlled database of glacier thickness observations - Welty, Ethan; Zemp, Michael; Navarro, Francisco; Huss, Matthias; Fürst, Johannes; Gärtner-Roer, Isabelle; Landmann, Johannes; Machguth, Horst; Naegeli, Kathrin; Andreassen, Liss M.; Farinotti, Daniel; Li, Huilin (Earth System Science Data, 2020)
Although worldwide inventories of glacier area have been coordinated internationally for several decades, a similar effort for glacier ice thicknesses was only initiated in 2013. Here, we present the third version of the Glacier Thickness Database (GlaThiDa v3), which includes 3 854 279 thickness measurements distributed over roughly 3000 glaciers worldwide. Overall, 14% of global glacier area is now within 1 km of a thickness measurement (located on the same glacier) - a significant improvement over GlaThiDa v2, which covered only 6% of global glacier area and only 1100 glaciers. Improvements in measurement coverage increase the robustness of numerical interpolations and model extrapolations, resulting in better estimates of regional to global glacier volumes and their potential contributions to sea-level rise. In this paper, we summarize the sources and compilation of glacier thickness data and the spatial and temporal coverage of the resulting database. In addition, we detail our use of open-source metadata formats and software tools to describe the data, validate the data format and content against this metadata description, and track changes to the data following modern data management best practices. Archived versions of GlaThiDa are available from the World Glacier Monitoring Service (e.g., v3.1.0, from which this paper was generated: https://doi.org/10.5904/wgms-glathida-2020-10; GlaThiDa Consortium, 2020), while the development version is available on GitLab (https://gitlab.com/wgms/glathida, last access: 9 November 2020).

Xylem anatomical responses of diffuse porous Chukrasia tabularis to climate in a South Asian moist tropical forest - Islam, Mahmuda; Rahman, Mizanur; Bräuning, Achim (Forest Ecology and Management, 2018)
Wood anatomical features such as vessels record paleo climatic and environmental signals through their physiological adjustment during the environmental stress condition. Using vessel features as environmental proxy is relatively new in tropical dendrochronology but very useful to study plant ecophysiological responses to changing environmental conditions. Here, we developed the first vessel chronologies of diffuse porous Chukrasia tabularis from a Bangladeshi moist tropical forest and assessed their suitability for Dendroclimatic and ecophysiological studies in moist tropical forests. Standard chronologies of ring-width (RW), vessel number (NV), mean vessel area (MVA), total vessel area (TVA), total vessel area % (TVAP), mean vessel tangential diameter (MVTD), mean vessel radial diameter (MVRD), and vessel density (VD) were developed which spanned the period 1925-2015. Principal component analysis revealed that all chronologies were related among each other, the first two principal axis explaining 80% of the common variance. Hence, all chronologies shared a common environmental signal, except TVAP and MVRD which were excluded from further dendroclimatic analysis. Bootstrap correlation function was used to test the relationship between the chronologies and climate variables over 1950-2015. All chronologies were significantly correlated with monthly, seasonal and annual climate variables but varied in their magnitude. Spring temperatures (March-April) and late monsoon precipitation had the dominant influence on the vessel features and radial growth of Chukrasia tabularis. Decreased vessel area (Hydraulic efficiency) and increased vessel density (Hydraulic safety) were observed in response to stress environmental condition particularly in the spring (hot and dry) when evapotranspiration became higher and soil moisture deficit occurs due to high temperatures. Moving correlation functions revealed stable climate tree-ring variable relationships during March-April and October with an increasing tendency of climate interaction in other months. Our study shows that vessel features in Chukrasia tabularis are highly sensitive to inter-annual climate variability and can be used for paleoclimatic and ecophysiological studies in moist tropical forests.

Xylem formation patterns from Mediterranean to subalpine climate conditions reveal high growth plasticity of pine species on Corsica - Häusser, Martin; Aryal, Sugam; Barth, Johannes; Bendix, Joerg; Garel, Emilie; van Geldern, Robert; Huneau, Frederic; Juhlke, Tobias; Knerr, Isabel; Santoni, Sebastien; Szymczak, Sonja; Trachte, Katja; et al. (Trees-Structure and Function, 2023)
Key messageBlack pine and Maritime pine exhibit considerable differences in growth phenology across elevation belts with a 1-month delay for xylogenesis and increasing growth rates from low, mid to high elevations.Investigating seasonal wood formation is crucial to understand tree growth responses to climate impact. The present study quantifies the variability of xylogenesis along an elevation gradient on the Mediterranean island of Corsica, where two native pine species (Pinus nigra Arnold ssp. laricio Maire and Pinus pinaster Aiton) grow from the upper tree line to sea level, partly in sympatry. We extracted microcores from 35 trees at 5 sites along an East-West transect from the coasts (10 m asl) to the island's central mountain ridge (1600 m asl) during bi-weekly sampling campaigns between 2017 and 2019. We applied generalised additive models to detect radial growth differences in elevation and species along with minimum temperatures for growth initiation. We found that trees in low elevations experienced over 2 months longer growth periods with higher maximum growth rates than in high elevations. The results show a 1-month delay for the beginning of tracheid formation between the low, mid and high-elevation belts but comparable timing for its termination. At the sites where both species co-occur, P. nigra accumulates more radial cells in a shorter time than P. pinaster. Trees at the two contrasting coastal sites have similar growth period lengths, but exhibit a time shift of over a month. Minimum temperatures around growth initiation vary between 3.1 degrees C for P. nigra and 9.9 degrees C for P. pinaster. These findings emphasise the high plasticity in the growth behaviour of one of the most widespread tree genera in Mediterranean and temperate zones.

YOUNG PEOPLE'S VISIONS FOR LIFE IN THE COUNTRYSIDE IN LATIN AMERICA - De La Vega-Leinert, A. Cristina; Kieslinger, Julia; Jimenez-Moreno, Marcela; Steinhauser, Cornelia (Geographical Review, 2021)
Abtract Young people steer their life trajectories against the backdrop of profound transformations of rurality. They are considered protagonists in the present and future of rural areas; however, their experiences and perspectives on life in, and away from, the countryside have been scarcely acknowledged in academia. Considering conceptual thoughts on new mobilities, place-based belonging, and new ruralities, we argue that young people are a highly dynamic and continually reassessing group. In four case studies realized independently in Argentina, Bolivia, Ecuador, and Mexico, we closely involved young people with multiple participative methods to express their perceptions, concerns, and demands. We experiment on ways to integrate our insights for future comparative studies. Beyond the diversity in local contexts, we found convergences in young people's visions, which motivate them to stay or leave, with wider implications for the sustainability of rural places. "Living in between" thereby encapsulates multifaceted hybrid possible countrysides away from constraining dichotomic views.

Zur Anwendung der Dendrochronologie in den Geowissenschaften - Bräuning, Achim (Erde, 1995)
Die Dendrochronologie stellt ein Verfahren zur jahrgenauen Datierung von Ereignissen dar, die sich im Jahrringbild von Bäumen an einem gegebenen Standort manifestieren. Das Jahrringmuster gibt in Form einer diskreten Zeitreihe die physiologische Konstitution sowie die Lebensspanne eines Baumes wieder, und kann so Hinweise auf klimatische, hydrologische, geomorphologische oder andere, die Variabilität des Wachstumsverlaufes verursachenden Agentien, enthalten. Daraus ergibt sich ein sehr weit gefasstes Anwendungsspektrum, dessen Interpretierbarkeit in manchen Fällen von der Unspezifität der Reaktion des Holzes begrenzt wird. Chemische Analysen der jahrgenau datierten Holzsubstanz können der Ermittlung der Umweltgeschichte oder - im Falle stabiler Isotope der Elemente H, O oder C - der Klimageschichte bzw. der Eichung des 14C-Kalenders dienen.

Zur Dendroklimatologie Hochtibets während des letzten Jahrtausends - Bräuning, Achim (J. Cramer in der Gebr. Borntraeger Verlagsbuchhandlung, 1999)
This study presents a the climatological results of a tree-ring study conducted in Eastern Tibet. The majority of the investigated sites are located at the timberline, so tree growth is primarily controlled by temperature. In total, 51 ring width chronologies from the trees of the genuses Picea, Abies, Larix, Pinus and Juniperus were compiled, the longest one from Juniper spanning 1546 years and dating back to 449 A. D. Furthermore, 20 chronologies of maximum latewood density were established, which were - like some ring width series, too - combined at some neighbouring sites with similar ecological conditions to regional chronologies with high sample depth. The sites of this sample network, which covers a large area, were divided into five dendroecological regions or growth provinces according to statistical tests like the sign-test, t-value, cross-correlation, Kendall's Tau and cluster analyses. In four of these regions which cover the moist eastern and southern margins of the Tibetan plateau and the mountain areas in the upper course of the meridional gorges, tree growth is mainly controlled by temperature. In contrast to this, growth is limited by the available moisture in the upper course of the Yarlung Tsangpo and at the western limit of forest distribution in Tibet. The statistical variance and sensitivity obtained from the tree-ring series of this dry forest-steppe-ecotone show high values in contrast to subalpine sites and point to a strong climatic signal in the chronologies of this region. The degree of similarity between the tree-ring lokations was not constant during the last 200 years, but variable in the course of smaller climatic fluctuations. Higher teleconnections, which point to a stronger common signal caused by more extreme climatic conditions, occured in the first half of the l9th and in the second half of the 20th century. Less similarity can be observed in the second half of the 1 9th and in the first half of the 20th century, indicating stronger influence of local stand characteristics and less extreme climatic conditions. The short period for which meteorological data series are available and which rarely span more than 40 years, and not seem to represent the amount of precipitation at the tree-ring sites adequately, made the use of simple statistics in the analyses of the climate-growth relationships advisable. In most cases, significant and ecologically meaningful relations between tree growth and controlling climatic factors could be derived applying correlation analyses and sign tests. Maximum latewood density is highly correlated with late summer temperature, ring width is strongly influenced by temperature conditions during the early winter months November and December prior to the growth scason. Growth rates of Juniper forests on southern exposures are determined by various climatic factors, firstly by the amount of precipitation during the growth year and by temperature during the vegetation period in the year prior to growth. In the dry growth province of southern Tibet, moisture conditions in the late summer of the year prior to growth play a decisive role for tree-ring formation. The quality of the statistical correlations between tree growth and climatic variables could be strongly improved by calculating regional means of tree-ring and climatic data within the predefined dendroecological regions. Smoothed chronologies of maximum latewood density show a strongly coherent low-frequency signal on a regional scale. Nevertheless, like in ring width series too, local disturbance signals like forest fires can be detected. Coherent growth patterns in ring width chronologies do occur in the dry growth province in southwestern Tibet and between subalpine sites in central eastern Tibet. Chronologies of Juniperus oflen show a stronger impact on growth of the local site conditions. The combination of consideration of ring width variation with the temporal variability of tree-ring parameters like variance, interval trend and percentage of pointer intervals clearly improves the scope of dendroclimatological interpretations of Juniper-chronologies. The periods from 800-86O, 920-104O, 1080-115O, 1410-153O, 1590-1680 with minimum temperatures around 1620-166O, furthermore 1695-1705, 1810-182O, 1830-1840 and 1905-1925 can be characterized as cool periods. Warmer conditions provailed aronnd 860-91O, 1150-138O, 1550-159O, 1675-169O, 1795-1805 and 1930- 1950. Dry phases in southern Tibet occured from 1750-177O, 1800-1805, 1820-1840, 1850-1865, 1885-1905, 1915-1930 and 1940-1955. Climatic fluctuations, which can be documented for the last 1000 years in the Northern hemisphere, like the Medieval Climatic Optimum and the Little Ice Age, occured in eastern Tibet essentially like in Middle Europe, althongh regional particularities in various climatic provinces of eastern Tibet can be shown.

Nonuniform late pleistocene glacier fluctuations in tropical Eastern Africa - Groos, Alexander R.; Akçar, Naki; Yesilyurt, Serdar; Miehe, Georg; Vockenhuber, Christof; Veit, Heinz (Science Advances, 2021)
Today's ice caps and glaciers in Africa are restricted to the highest peaks, but during the Pleistocene, several mountains on the continent were extensively glaciated. However, little is known about regional differences in the timing and extent of past glaciations and the impact of paleoclimatic changes on the afro-alpine environment and settlement history. Here, we present a glacial chronology for the Ethiopian Highlands in comparison with other East African Mountains. In the Ethiopian Highlands, glaciers reached their maximum 42 to 28 ka thousand years ago before the global Last Glacial Maximum. The local maximum was accompanied by a temperature depression of 4.4° to 6.0°C and a 700-m downward shift of the afro-alpine vegetation belt, reshaping the human and natural habitats. The chronological comparison reveals that glaciers in Eastern Africa responded in a nonuniform way to past climatic changes, indicating a regionally varying influence of precipitation, temperature, and orography on paleoglacier dynamics.

Redistribution and realization of energy at different scale-hierarchical levels of coalrock massif - Sielski, Anna; Bezruchko, Kostiantyn; Pymonenko, Liudmyla; Burchak, Oleksandr; Karhapolov, Andrii; Baranovskyi, Volodymyr (E3S Web of Conferences, 2020)
The research of redistribution and realization of energy at different scale-hierarchical levels at the Donbas coalrock massif based on the parameters of faultings and gas-dynamic phenomena has been conducted. It is proved that the energy transfer, incoming by impulses in post-inversion time of the geological development in Donbas, occurs throughout the whole structure of coal, due to the formation of energy connection between individual elements of the molecular structure. This process is accompanied by transition of free energy into a bound state with increase in ordering of the molecular structure and aromaticity of the coal substance (local increase in the degree of catagenetic transformations). The conditions of energy accumulation and realization depend on the peculiarities of molecular processes occurring in dislocations of different types. Less energy is accumulated in tensile zones than in compression zones, which is confirmed by the intensity of coal and gas outbursts. It has been established that the energy entering the multifractal geological environment in Donbas from external sources is also redistributed fractionally by the system, causing the formation of multiscale discrete inhomogeneities, which provides the massif with specific properties and ability to self-organization. A fractal model of the structure of the coalrock massif is proposed.

The enigma of relict large sorted stone stripes in the tropical Ethiopian Highlands - Groos, Alexander R.; Niederhauser, Janik; Wraase, Luise; Haensel, Falk; Nauss, Thomas; Akçar, Naki; Veit, Heinz (Earth Surface Dynamics, 2021)
Large forms of sorted patterned ground belong to the most prominent geomorphic features of periglacial and permafrost environments of the mid-latitudes and polar regions, but they were hitherto unknown in the tropics. Here, we report on relict large sorted stone stripes (up to 1000m long, 15m wide, and 2m deep) on the ca. 4000m high central Sanetti Plateau of the tropical Bale Mountains in the southern Ethiopian Highlands. These geomorphic features are enigmatic since forms of patterned ground exceeding several metres are commonly associated with distinct seasonal ground temperatures, oscillating around 0 °C. To systematically investigate present frost phenomena and relict periglacial landforms in the Bale Mountains, we conducted extensive geomorphological mapping. The sorted stone stripes were studied in more detail by applying aerial photogrammetry, ground-penetrating radar measurements, and 36Cl surface exposure dating. In addition, we installed ground temperature data loggers between 3877 and 4377m to analyse present frost occurrence and seasonal ground temperature variations. Superficial nocturnal ground frost was measured at 35-90 d per year, but the ground beneath the upper few centimetres remains unfrozen the entire year. Seasonal frost occurrence would require a mean annual ground temperature depression of about 11 °C, corresponding to an air temperature decrease of about 6-8 °C (relative to today) as inferred from a simple statistical ground temperature model experiment. Our results suggest the formation of the large sorted stone stripes under past periglacial conditions related to lateral and vertical frost sorting in the course of cyclic freezing and thawing of the ground. It is likely that the stone stripes formed either in proximity to a former ice cap on the Sanetti Plateau over the last glacial period due to seasonal frost heave and sorting or they developed over multiple cold phases during the Pleistocene. Although certain aspects of the genesis of the large sorted stone stripes remain unresolved, the presence of these geomorphic features provides independent evidence besides glacial landforms for unprecedented palaeoclimatic and palaeoenvironmental changes in the tropical Bale Mountains during the (Late) Pleistocene.

The potential of low-cost UAVs and open-source photogrammetry software for high-resolution monitoring of alpine glaciers: A case study from the kanderfirn (Swiss Alps) - Groos, Alexander R.; Bertschinger, Thalia; Kummer, Céline; Erlwein, Sabrina; Munz, Lukas; Philipp, Andreas (Geosciences, 2019)
Unmanned Aerial Vehicles (UAV) are a rapidly evolving tool in geosciences and are increasingly deployed for studying the dynamic processes of the earth's surface. To assess the potential of autonomous low-cost UAVs for the mapping and monitoring of alpine glaciers, we conducted multiple aerial surveys on the Kanderfirn in the Swiss Alps in 2017 and 2018 using open hardware and software of the Paparazzi UAV project. The open-source photogrammetry software OpenDroneMap was tested for the generation of high-resolution orthophotos and digital surface models (DSMs) from aerial imagery and cross-checked with the well-established proprietary software Pix4D. Accurately measured ground control points served for the determination of the geometric accuracy of the orthophotos and DSMs. A horizontal (xy) accuracy of 0.7-1.2 m and a vertical (z) accuracy of 0.7-2.1 m was achieved for OpenDroneMap, compared to a xy-accuracy of 0.3-0.5 m and a z-accuracy of 0.4-0.5 m obtained for Pix4D. Based on the analysis and comparison of different orthophotos and DSMs, surface elevation, roughness and brightness changes from 3 June to 29 September 2018 were quantified. While the brightness of the glacier surface decreased linearly over the ablation season, the surface roughness increased. The mean DSM-based elevation change across the glacier tongue was 8 m, overestimating the measured melting and surface lowering at the installed ablation stakes by about 1.5 m. The presented results highlight that self-built fixed-wing UAVs in tandem with open-source photogrammetry software are an affordable alternative to commercial remote-sensing platforms and proprietary software. The applied low-cost approach also provides great potential for other regions and geoscientific disciplines.
