Abstract

Terpenes may be converted by electrochemical oxidation to various oxidized products with appealing aroma properties. In this study, (R)-limonene was anodically oxidized in the presence of ethanol, and the resulting mixture exhibited a pleasing fruity, herbal, citrus-like, and resinous odor. The aroma-active compounds were purified by means of preparative high-performance liquid chromatography, and their structures were elucidated by means of gas chromatography (GC)-mass spectrometry and nuclear magnetic resonance spectroscopy. In addition, the odor of the isolated compounds was determined by means of GC-olfactometry. Seventeen compounds were isolated, and for only four of them, analytical data had been reported previously in the literature. Furthermore, only for two of the compounds, an odor description had been available in the literature.

Abstract

The thawing of alpine permafrost in a warmer climate may alter the runoff regime of high alpine catchments. We present a case study where detailed geophysical and geological field investigations were performed in a 5 km2 large catchment in Western Austria to assess its main hydrogeological settings. Ground-penetrating radar data, seismic refraction measurements and ground-surface-temperature data were employed to map the spatial permafrost distribution and depth of the permafrost table and the bedrock interface. The results for different types of unconsolidated sediments were then translated into five sets of flow path concepts in the presence and absence of permafrost. These concepts were then used to set up a rainfall-runoff model and simulate the runoff response of the catchment for scenarios with and without permafrost. The simulations indicate that the complete thawing of permafrost will increase the catchment storage capacity which will reduce the flood peaks by up to 20% and increase runoff during recession by about 15%. The reduction of extreme events is important since it may also affect flood events in downstream catchments. The study highlights the importance of interdisciplinary work between hydrology, geophysics and geology which can greatly help to improve the understanding of subsurface processes.

Abstract

Alpine permafrost is prone to decrease in a warmer climate as a consequence of climate change which in turn may affect the runoff regime of high alpine catchments. In the presented case study detailed geophysical field investigations were performed in a 5 km2 large catchment in Western Austria to gain information about subsurface properties and permafrost occurrence. Ground penetrating radar, seismic refraction and ground-surface-temperature measurements were applied to map the spatial permafrost distribution, depths to the permafrost table and bedrock interface. This information was used to infer subsurface flow paths concepts for different geologic formations in the presence and absence of permafrost. The concepts were then used to set up a rainfall-runoff model and simulate the runoff response of the catchment for scenarios with and without permafrost. The results of the study show that geophysical information helps to improve the understanding of subsurface processes and to reduce the parameter identifiability problem. Subsurface model parameters are well constrained by the available field information and require little calibration. Furthermore, the simulations indicate that the melting of permafrost increases the available catchment storage which causes a reduction of flood peaks and an increase of runoff during recession. A reduction of extreme events is important since it may also affect flood events in downstream catchments.

31. Atmospheric warming threatens the untapped glacial archive of Ortles mountain, South Tyrol

Author

Abstract

Ortles mountain (3905 m a.s.l.), South Tyrol, Italy, is the highest mountain of the Eastern European Alps, and its upper glacier, Alto dell'Ortles, presents a unique opportunity to obtain the first paleoenvironmental record from an ice core in this area. To study the suitability of this glacier as a drilling site, in 2009 we performed the first preliminary study of its glaciological characteristics at similar to 3830 m a.s.l. The maximum thickness is similar to 75 m, and lamination of the exposed ice layers is excellent down to bedrock. Firn and ice lenses were observed in a 10 m shallow core, and the firn/ice transition was below similar to 24 m. The seasonal chemical signal is clearly preserved only within the uppermost 2008 and 2009 snow/firn. A simple mass-balance model, the incipient 'smoothing' of the chemical record, and the observed ice lenses provide evidence that melting, infiltration and refreezing cycles occurred within the urn layers formed before 2008. Nevertheless, the mass balance of the upper part of Alto dell'Ortles was positive (similar to 800 mm a(-1)) during the last few years. We suggest that an environmental history is likely to be well preserved only within the ice layers formed before similar to 1980, when summer air temperature was similar to 2 degrees C colder than today in this area. Clearly the continued warming trend predicted to occur over the next few decades, and the consequent increase in frequency and/or intensity of infiltration processes, will endanger the preservation of the glacial archive conserved in the deep ice layers of Ortles mountain.

Abstract

International audience; As sediment conveyors, rockglaciers - and more generally the creep of perennially frozen ground may be the source of slope instability processes (e.g. rock falls, debris flows) on steep valley sides in a mountain environment. Any change in the rate of permafrost creep is susceptible to affect both the frequency and magnitude of related slope instabilities. There is currently an increasing interest in the densely inhabitated European Alps to document the behaviour of the high-altitude permafrost environment. Studies on rock glacier dynamics have shown that three superimposed types of temporal variability in surface motion can be envisaged at a secular scale: a seasonal rhythm, changes in annual mean velocities, a decadal to pluri-decadal trend. The present contribution compares and analyses the variations in annual velocities that have been observed at the surface of rock glaciers in the European Alps since 2002/03. It represents a pioneer attempt to synthesize the annual variations of rockglaciers activity at this scale. Short-term changes in surface motion of rockglaciers have been monitored in the European Alps since a few years by several research groups, mostly by means of real time kinematics GPS or geodetic survey using a total station. Annual series have been acquired between 2002/03 and 2006/07 on more than 13 rockglaciers located in different parts of the alpine arc. The provided dataset is analysed paying regard especially to two extreme warm climatic events that affected the European alpine region during the 2003-2007 period: the heat wave of summer 2003 and the 2006-07 warm swell, namely a 15-month period of quasi continuous large positive temperature anomaly between April 2006 and June 2007. Despite different size, morphology, ice content, complexity of flow field, mean annual velocity, seasonal rhythm, etc., the compared rockglaciers have surprisingly shown so far a rather homogeneous and synchronous behaviour since 2003: most of them reached a maximal rate of activity in 2003/04 before that their horizontal velocity dropped drastically in 2004/05 and 2005/06. First results in 2006/07 indicate, at least in the western Swiss Alps, a stabilisation or even a slight increase of velocities. The relative range of variation has reached 20 to more than 50 % in one or two years. The absolute range of variation is much larger for rapidly moving rock glacier. Interannual changes appear to be well related to mean annual ground surface temperature shifts with a delay of approximately 6-12 months reflecting their propagation deeper into permafrost.

Abstract

Recent interannual variation of rockglaciers surface motion is compared for 16 landforms monitored since a few years in various parts of the European Alps. Large fluctuations have been observed particularly since 2002. The investigated rockglaciers have shown mostly similar behavior whatever their location in the Alpine arc, their size or their velocity. The observed interannual variations appear to be primarily related to external climatic factors rather than to internal characteristics. They are mostly well correlated to mean annual ground surface temperature shifts with a delay of approximately 6-12 months reflecting their propagation deeper into permafrost. Other seasonal factors may play a significant role: a lower intensity of winter ground freezing and/or a larger winter snow accumulation appear to facilitate a higher rate of rockglaciers surface motion., Les variations récentes des déplacements de surface de 16 glaciers rocheux suivis depuis quelques années sont comparés pour 16 appareils. De larges fluctuation sont observées depuis 2002 en particulier. Les glaciers étudiés montrent des comportement similaires à l'échelle de l'ensemble de l'arc alpin. Les variations interannuelles semblent être reliées aux conditions climatiques et non à la structure interne. Elles sont bien corrélées aux température moyenne annuelles de surface avec un temps de réponse de l'ordre de 6-12 mois lié la diffusion d'énergie dans le permafrost. D'autres facteurs saisonniers jouent un rôle significatif: une plus faible accumulation hivernale de neige favorise un déplacement de surface plus élevé.

45. Optische Spektroskopie an bestrahlungsinduzierten Punktdefekten in Galliumarsenid und Indiumphosphid

Abstract

Semiinsulating GaAs and InP as well as n- and p-doped GaAs has been irradiated at 4 K with electrons of energies between 0.4 and 3 .0 MeV and with total irradiation doses between 10$^{17}$ e$^{-}$/cm$^{2}$ and 10$^{19}$ e$^{-}$/cm$^{2}$. The irradiation induced point defects and their thermally activated reactions in the temperature range from 4 K to 870 K have been investigated by measurements of the infrared absorption and of the magnetic circular dichroism of the absorption (MCDA). For GaAs the discussion focuses on the evaluation of the known MCDA "fingerprints" of 4 different AsGa related defects (EL2, As$_{Ga}$-X$_{i}$), as well as two spectra related to Gallium vacancies : the well known V$_{Ga}$-X-spectrum and a new spectrum labeled XGa that bothanneal around 300 K. As the new X$_{Ga}$-spectrum is observed after 0.4 MeV irradiation and the V$_{Ga}$-X-spectrum only for E$_{e^-}$ > 0.5 MeV we attribute the V$_{Ga}$-X-spectrum to complexes formed by double displacements. In addition to the X$_{Ga}$-defects the 0.4 MeV irradiation produces also the A$_{S_{Ga}}$- X$_{1}$ defect. This shows directly that both sublattices are involved in the damage even at the lowest energies. The different observability of the paramagnetic charge states of the different A$_{S_{Ga}}$ related complexes as a function of doping, irradiation dose and annealing temperature could consistantly be explained. In s.i. InP we observed two new MCDA spectra that are visible directly after irradiation and anneal between 140 K and 230 K. Along with the annealing of these spectra that we attribute to close frenkel pairs the spectrum of radiation induced P$_{In}$ antisites becomes visible. The similarity of the defect reactions in both III-V-compounds are further discussed.
