Heat and freshwater fluxes from basal ice shelf melting (ISM) are parameterized following Beckmann and Goosse [Ocean Model 5(2):157-170, 2003]. Melting sensitivities to the oceanic temperature outside of the ice shelf cavities are varied from linear to quadratic (Holland et al. in J Clim 21, 2008). In 1\% per year CO2-increase experiments the total freshwater flux from ISM triples to 0.09 Sv in the linear case and more than quadruples to 0.15 Sv in the quadratic case after 140 years at which 4 x 280 ppm = 1,120 ppm was reached. Due to the long response time of subsurface temperature anomalies, ISM thereafter increases drastically, if CO2 concentrations are kept constant at 1,120 ppm. Varying strength of the Antarctic circumpolar current (ACC) is crucial for ISM increase, because southward advection of heat dominates the warming along the Antarctic coast. On centennial timescales the ACC accelerates due to deep ocean warming north of the current, caused by mixing of heat along isopycnals in the Southern Ocean (SO) outcropping regions. In contrast to previous studies we find an initial weakening of the ACC during the first 150 years of warming. This purely baroclinic effect is due to a freshening in the SO which is consistent with present observations. Comparison with simulations with diagnosed ISM but without its influence on the ocean circulation reveal a number of ISM-related feedbacks, of which a negative ISM-feedback, due to the ISM-related local oceanic cooling, is the dominant one.}, language = {en} } @article{BornLevermann2010, author = {Born, Andreas and Levermann, Anders}, title = {The 8.2 ka event : abrupt transition of the subpolar gyre toward a modern North Atlantic circulation}, issn = {1525-2027}, doi = {10.1029/2009gc003024}, year = {2010}, abstract = {Climate model simulations of the 8.2 ka event show an abrupt strengthening of the Atlantic subpolar gyre that allows us to connect two major but apparently contradictory climate events of the early Holocene: the freshwater outburst from proglacial lakes and the onset of Labrador Sea water formation. The 8.2 ka event is the largest climatic signal of our present interglacial with a widespread cooling in the North Atlantic region about 8200 years before present. It coincides with a meltwater outburst from North American proglacial lakes that is believed to have weakened the Atlantic meridional overturning circulation and northward heat transport, followed by a recovery of the deep ocean circulation and rising temperatures after a few centuries. Marine proxy data, however, date the onset of deep water formation in Labrador Sea to the same time. The subsequent strengthening of the slope current system created a regional signal recorded as an abrupt and persistent surface temperature decrease. Although similarities in timing are compelling, a mechanism to reconcile these apparently contradictory events was missing. Our simulations show that an abrupt and persistent strengthening of the Atlantic subpolar gyre provides a plausible explanation. The intense freshwater pulse triggered a transition of the gyre circulation into a different mode of operation, stabilized by internal feedbacks and persistent after the cessation of the perturbation. As a direct consequence, deep water formation around its center intensifies. This corresponds to the modern flow regime and stabilizes the meridional overturning circulation, possibly contributing to the Holocene's climatic stability.}, language = {en} } @book{RichterEdeling2010, author = {Richter, Peter and Edeling, Thomas}, title = {Zwischen Entlastung und dem Traum von Wohlstand}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-102-8}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-48199}, publisher = {Universit{\"a}t Potsdam}, pages = {155}, year = {2010}, abstract = {Ausgehend von der These, dass kommunale Unternehmen gerade in strukturschwachen Regionen eine besondere politische und wirtschaftliche Bedeutung besitzen, wird die Entwicklung der kommunalen Wirtschaft im Land Brandenburg untersucht.

Streitpunkte waren sowohl die organisationsrechtliche Zuordnung der Tr{\"a}gerschaft (ARGE, Optionskommunen) als auch Voraussetzungen, Art und H{\"o}he der Leistungen nach dem damals neuen SGB II. Inzwischen hat das Bundesverfassungsgericht die in \S 44b SGB II geregelten Arbeitsgemeinschaften als verfassungswidrige Mischverwaltung eingestuft. Die Karlsruher Richter setzten dem Gesetzgeber f{\"u}r die Herstellung grundgesetzkonformer Zust{\"a}nde eine Frist l{\"a}ngstens bis Ende 2010. Mit Gesetz zur {\"A}nderung des Grundgesetzes (Art. 91e), in Kraft getreten am 27.07.2010, hat der Gesetzgeber den Auftrag des Bundesverfassungsgerichtes umgesetzt. Die Verfassung wurde um einen neuen Artikel 91e erg{\"a}nzt. Er schafft eine verfassungsrechtliche Grundlage f{\"u}r die Fortsetzung der Aufgabenwahrnehmung der SGB II-Leistungstr{\"a}ger in gemeinsamen Einrichtungen. Dadurch wird eine Ausnahme vom Verbot der Mischverwaltung f{\"u}r das Gebiet der Grundsicherung f{\"u}r Arbeitsuchende eingef{\"u}hrt. Nach Art. 91e Abs. 2 GG kann eine begrenzte Anzahl von kommunalen Tr{\"a}gern als alleinige Tr{\"a}ger der Grundsicherung f{\"u}r Arbeitssuchende zugelassen werden.

In particular, the development of amplifier lakes in rift basins after three million years ago significantly contributed to this exceptional sensitivity of East Africa to climate change compared to elsewhere on the African continent. Amplifier lakes are characterized by tectonically-formed graben morphologies in combination with an extreme contrast between high precipitation in the elevated parts of the catchment and high evaporation in the lake area. Such amplifier lakes respond rapidly to moderate, precessional-forced climate shifts, and as they do so apply dramatic environmental pressure to the biosphere. Rift basins, when either extremely dry or lake-filled, form important barriers for migration, mixing and competition of different populations of animals and hominins. Amplifier lakes link long-term, high-amplitude tectonic processes and short-term environmental fluctuations.

This uncertainty stems from the lack of datable, geomorphically meaningful reference horizons that could record surface uplift. Here, we document the existence of significant relief along the East African Plateau prior to rifting, as inferred from modeling the emplacement history of one of the longest terrestrial lava flows, the similar to 300-km-long Yatta phonolite flow in Kenya. This 13.5 Ma lava flow originated on the present-day eastern Kenya Rift flank, and utilized a riverbed that once routed runoff from the eastern rim of the plateau. Combining an empirical viscosity model with subsequent cooling and using the Yatta lava flow geometry and underlying paleotopography (slope angle), we found that the prerift slope was at least 0.2 degrees, suggesting that the lava flow originated at a minimum elevation of 1400 m. Hence, high paleotopography in the Kenya Rift region must have existed by at least 13.5 Ma.

Over the past decades, several studies have described extensional features, not only in the Tibetan Plateau, but also in the Himalaya. For a long time, the favored model explained the function of the Southern Tibetan detachment system, a major fault zone in the Himalaya, as a decoupling horizon between the regime of crustal shortening forming the Himalayan wedge to the south and the extensional regime of the Tibetan Plateau to the north. However, in recent years, increasing evidence has shown that N-S-trending normal faults in the Central Himalaya crosscut not only the Southern Tibetan detachment system, but also the Main Central thrust. Here, we present new structural data and geologic evidence collected within the NW Indian Himalaya and combine them with previously published seismicity data sets in order to document pervasive E-W extension accommodated along N-S-trending faults extending as far south as the footwall of the Main Central thrust. We conducted a kinematic analysis of fault striations on brittle faults, documented and mapped fault scarps in Quaternary sedimentary deposits using satellite imagery, and made field observations in the Greater Sutlej region (Spiti, Lahul, Kinnaur) and the Garhwal Himalaya. Studies of extensional features within the regionally NW- SE-trending NW Indian Himalaya provide the advantage that arc-parallel and E-W extension can be separated, in contrast to the Central Himalaya. Therefore, our observations of E-W extension in the Indian NW Himalaya are well suited to test the applicability of current tectonic models for the whole Himalaya. We favor the interpretation of E-W extension in the NW Indian Himalaya as a propagation of extension driven by collapse of the Tibetan Plateau.}, language = {en} } @phdthesis{Landgraf2010, author = {Landgraf, Angela}, title = {Fault interaction at different time- and length scales : the North Tehran thrust and Mosha-Fasham fault (Alborz mountains, Iran)}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-50800}, school = {Universit{\"a}t Potsdam}, year = {2010}, abstract = {The seismically active Alborz mountains of northern Iran are an integral part of the Arabia-Eurasia collision. Linked strike-slip and thrust/reverse-fault systems in this mountain belt are characterized by slow loading rates, and large earthquakes are highly disparate in space and time. Similar to other intracontinental deformation zones such a pattern of tectonic activity is still insufficiently understood, because recurrence intervals between seismic events may be on the order of thousands of years, and are thus beyond the resolution of short term measurements based on GPS or instrumentally recorded seismicity. This study bridges the gap of deformation processes on different time scales. In particular, my investigation focuses on deformation on the Quaternary time scale, beyond present-day deformation rates, and it uses present-day and paleotectonic characteristics to model fault behavior. The study includes data based on structural and geomorphic mapping, faultkinematic analysis, DEM-based morphometry, and numerical fault-interaction modeling. In order to better understand the long- to short term behavior of such complex fault systems, I used geomorphic surfaces as strain markers and dated fluvial and alluvial surfaces using terrestrial cosmogenic nuclides (TCN, 10Be, 26Al, 36Cl) and optically stimulated luminescence (OSL). My investigation focuses on the seismically active Mosha-Fasham fault (MFF) and the seismically virtually inactive North Tehran Thrust (NTT), adjacent to the Tehran metropolitan area. Fault-kinematic data reveal an early mechanical linkage of the NTT and MFF during an earlier dextral transpressional stage, when the shortening direction was oriented northwest. This regime was superseded by Pliocene to Recent NE-oriented shortening, which caused thrusting and sinistral strike-slip faulting. In the course of this kinematic changeover, the NTT and MFF were reactivated and incorporated into a nascent transpressional duplex, which has significantly affected landscape evolution in this part of the range. Two of three distinctive features which characterize topography and relief in the study area can be directly related to their location inside the duplex array and are thus linked to interaction between eastern MFF and NTT, and between western MFF and Taleghan fault, respectively. To account for inferred inherited topography from the previous dextral-transpression regime, a new concept of tectonic landscape characterization has been used. Accordingly, I define simple landscapes as those environments, which have developed during the influence of a sustained tectonic regime. In contrast, composite landscapes contain topographic elements inherited from previous tectonic conditions that are inconsistent with the regional present-day stress field and kinematic style. Using numerical fault-interaction modeling with different tectonic boundary conditions, I calculated synoptic snapshots of artificial topography to compare it with the real topographic metrics. However, in the Alborz mountains, E-W faults are favorably oriented to accommodate the entire range of NW- to NE-directed compression. These faults show the highest total displacement which might indicate sustained faulting under changing boundary conditions. In contrast to the fault system within and at the flanks of the Alborz mountains, Quaternary deformation in the adjacent Tehran plain is characterized by oblique motion and thrust and strike-slip fault systems. In this morphotectonic province fault-propagation folding along major faults, limited strike-slip motion, and en-{\´e}chelon arrays of second-order upper plate thrusts are typical. While the Tehran plain is characterized by young deformation phenomena, the majority of faulting took place in the early stages of the Quaternary and during late Pliocene time. TCN-dating, which was performed for the first time on geomorphic surfaces in the Tehran plain, revealed that the oldest two phases of alluviation (units A and B) must be older than late Pleistocene. While urban development in Tehran increasingly covers and obliterates the active fault traces, the present-day kinematic style, the vestiges of formerly undeformed Quaternary landforms, and paleo earthquake indicators from the last millennia attest to the threat that these faults and their related structures pose for the megacity.}, language = {en} } @article{ToeroekBergerKliem2010, author = {T{\"o}r{\"o}k, Tibor and Berger, Mitch A. and Kliem, Bernhard}, title = {The writhe of helical structures in the solar corona}, issn = {0004-6361}, doi = {10.1051/0004-6361/200913578}, year = {2010}, abstract = {Context. Helicity is a fundamental property of magnetic fields, conserved in ideal MHD. In flux rope geometry, it consists of twist and writhe helicity. Despite the common occurrence of helical structures in the solar atmosphere, little is known about how their shape relates to the writhe, which fraction of helicity is contained in writhe, and how much helicity is exchanged between twist and writhe when they erupt. Aims. Here we perform a quantitative investigation of these questions relevant for coronal flux ropes. Methods. The decomposition of the writhe of a curve into local and nonlocal components greatly facilitates its computation. We use it to study the relation between writhe and projected S shape of helical curves and to measure writhe and twist in numerical simulations of flux rope instabilities. The results are discussed with regard to filament eruptions and coronal mass ejections (CMEs). Results. (1) We demonstrate that the relation between writhe and projected S shape is not unique in principle, but that the ambiguity does not affect low- lying structures, thus supporting the established empirical rule which associates stable forward (reverse) S shaped structures low in the corona with positive (negative) helicity. (2) Kink-unstable erupting flux ropes are found to transform a far smaller fraction of their twist helicity into writhe helicity than often assumed. (3) Confined flux rope eruptions tend to show stronger writhe at low heights than ejective eruptions (CMEs). This argues against suggestions that the writhing facilitates the rise of the rope through the overlying field. (4) Erupting filaments which are S shaped already before the eruption and keep the sign of their axis writhe (which is expected if field of one chirality dominates the source volume of the eruption), must reverse their S shape in the course of the rise. Implications for the occurrence of the helical kink instability in such events are discussed. (5) The writhe of rising loops can easily be estimated from the angle of rotation about the direction of ascent, once the apex height exceeds the footpoint separation significantly. Conclusions. Writhe can straightforwardly be computed for numerical data and can often be estimated from observations. It is useful in interpreting S shaped coronal structures and in constraining models of eruptions.}, language = {en} } @article{ValoriKliemToeroeketal.2010, author = {Valori, Gherardo and Kliem, Bernhard and T{\"o}r{\"o}k, Tibor and Titov, Viacheslav S.}, title = {Testing magnetofrictional extrapolation with the Titov-Demoulin model of solar active regions}, issn = {0004-6361}, doi = {10.1051/0004-6361/201014416}, year = {2010}, abstract = {We examine the nonlinear magnetofrictional extrapolation scheme using the solar active region model by Titov and Demoulin as test field. This model consists of an arched, line-tied current channel held in force-free equilibrium by the potential field of a bipolar flux distribution in the bottom boundary. A modified version with a parabolic current density profile is employed here. We find that the equilibrium is reconstructed with very high accuracy in a representative range of parameter space, using only the vector field in the bottom boundary as input. Structural features formed in the interface between the flux rope and the surrounding arcade - "hyperbolic flux tube" and "bald patch separatrix surface" - are reliably reproduced, as are the flux rope twist and the energy and helicity of the configuration. This demonstrates that force-free fields containing these basic structural elements of solar active regions can be obtained by extrapolation. The influence of the chosen initial condition on the accuracy of reconstruction is also addressed, confirming that the initial field that best matches the external potential field of the model quite naturally leads to the best reconstruction. Extrapolating the magnetogram of a Titov-Demoulin equilibrium in the unstable range of parameter space yields a sequence of two opposing evolutionary phases, which clearly indicate the unstable nature of the configuration: a partial buildup of the flux rope with rising free energy is followed by destruction of the rope, losing most of the free energy.}, language = {en} } @article{CarrapaHauerSchoenbohmetal.2010, author = {Carrapa, Barbara and Hauer, Joern and Schoenbohm, Lindsay M. and Strecker, Manfred and Schmitt, Axel K. and Villanueva, Arturo and Gomez, Jos{\´e} Sosa}, title = {Dynamics of deformation and sedimentation in the northern Sierras Pampeanas : an integrated study of the Neogene Fiambal{\´a} basin, NW Argentina ; reply}, issn = {0016-7606}, doi = {10.1130/B30134.1}, year = {2010}, language = {en} } @phdthesis{Scherler2010, author = {Scherler, Dirk}, title = {Climate variability and glacial dynamics in the Himalaya}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-49871}, school = {Universit{\"a}t Potsdam}, year = {2010}, abstract = {In den Hochgebirgen Asiens bedecken Gletscher eine Fl{\"a}che von ungef{\"a}hr 115,000 km² und ergeben damit, neben Gr{\"o}nland und der Antarktis, eine der gr{\"o}ßten Eisakkumulationen der Erde. Die Sensibilit{\"a}t der Gletscher gegen{\"u}ber Klimaschwankungen macht sie zu wertvollen pal{\"a}oklimatischen Archiven in Hochgebirgen, aber gleichzeitig auch anf{\"a}llig gegen{\"u}ber rezenter und zuk{\"u}nftiger globaler Erw{\"a}rmung. Dies kann vor allem in dicht besiedelten Gebieten S{\"u}d-, Ost- und Zentralasiens zu großen Problem f{\"u}hren, in denen Gletscher- und Schnee-Schmelzw{\"a}sser eine wichtige Ressource f{\"u}r Landwirtschaft und Stromerzeugung darstellen. Eine erfolgreiche Prognose des Gletscherverhaltens in Reaktion auf den Klimawandel und die Minderung der sozio{\"o}konomischen Auswirkungen erfordert fundierte Kenntnisse der klimatischen Steuerungsfaktoren und der Dynamik asiatischer Gletscher. Aufgrund ihrer Abgeschiedenheit und dem erschwerten Zugang gibt es nur wenige glaziologische Gel{\"a}ndestudien, die zudem r{\"a}umlich und zeitlich sehr begrenzt sind. Daher fehlen bisher grundlegende Informationen {\"u}ber die Mehrzahl asiatischer Gletscher. In dieser Arbeit benutze ich verschiedene Methoden, um die Dynamik asiatischer Gletscher auf mehreren Zeitskalen zu untersuchen. Erstens teste ich eine Methode zur pr{\"a}zisen satelliten-gest{\"u}tzten Messung von Gletscheroberfl{\"a}chen-Geschwindigkeiten. Darauf aufbauend habe ich eine umfassende regionale Erhebung der Fliessgeschwindigkeiten und Frontdynamik asiatischer Gletscher f{\"u}r die Jahre 2000 bis 2008 durchgef{\"u}hrt. Der gewonnene Datensatz erlaubt einmalige Einblicke in die topographischen und klimatischen Steuerungsfaktoren der Gletscherfließgeschwindigkeiten in den Gebirgsregionen Hochasiens. Insbesondere dokumentieren die Daten rezent ungleiches Verhalten der Gletscher im Karakorum und im Himalaja, welches ich auf die konkurrierenden klimatischen Einfl{\"u}sse der Westwinddrift im Winter und des Indischen Monsuns im Sommer zur{\"u}ckf{\"u}hre. Zweitens untersuche ich, ob klimatisch bedingte Ost-West Unterschiede im Gletscherverhalten auch auf l{\"a}ngeren Zeitskalen eine Rolle spielen und gegebenenfalls f{\"u}r dokumentierte regional asynchrone Gletschervorst{\"o}ße relevant sind. Dazu habe ich mittels kosmogener Nuklide Oberfl{\"a}chenalter von erratischen Bl{\"o}cken auf Mor{\"a}nen ermittelt und eine glaziale Chronologie f{\"u}r das obere Tons Tal, in den Quellgebieten des Ganges, erstellt. Dieses Gebiet befindet sich in der {\"U}bergangszone von monsunaler zu Westwind beeinflusster Feuchtigkeitszufuhr und ist damit ideal gelegen, um die Auswirkungen dieser beiden atmosph{\"a}rischen Zirkulationssysteme auf Gletschervorst{\"o}ße zu untersuchen. Die ermittelte glaziale Chronologie dokumentiert mehrere Gletscherschwankungen w{\"a}hrend des Endstadiums der letzten Pleistoz{\"a}nen Vereisung und w{\"a}hrend des Holz{\"a}ns. Diese weisen darauf hin, dass Gletscherschwankungen im westlichen Himalaja weitestgehend synchron waren und auf graduelle glaziale-interglaziale Temperaturver{\"a}nderungen, {\"u}berlagert von monsunalen Niederschlagsschwankungen h{\"o}herer Frequenz, zur{\"u}ck zu f{\"u}hren sind. In einem dritten Schritt kombiniere ich Satelliten-Klimadaten mit Eisfluss-Absch{\"a}tzungen und topographischen Analysen, um den Einfluss der Gletscher Hochasiens auf die Reliefentwicklung im Hochgebirge zu untersuchen. Die Ergebnisse dokumentieren ausgepr{\"a}gte meridionale Unterschiede im Grad und im Stil der Vergletscherung und glazialen Erosion in Abh{\"a}ngigkeit von topographischen und klimatischen Faktoren. Gegens{\"a}tzlich zu bisherigen Annahmen deuten die Daten darauf hin, dass das monsunale Klima im zentralen Himalaja die glaziale Erosion schw{\"a}cht und durch den Erhalt einer steilen orographischen Barriere das Tibet Plateau vor lateraler Zerschneidung bewahrt. Die Ergebnisse dieser Arbeit dokumentieren, wie klimatische und topographische Gradienten die Gletscherdynamik in den Hochgebirgen Asiens auf Zeitskalen von 10^0 bis 10^6 Jahren beeinflussen. Die Reaktionszeit der Gletscher auf Klimaver{\"a}nderungen sind eng an Eigenschaften wie Schuttbedeckung und Neigung gekoppelt, welche ihrerseits von den topographischen Verh{\"a}ltnissen bedingt sind. Derartige Einflussfaktoren m{\"u}ssen bei pal{\"a}oklimatischen Rekonstruktion und Vorhersagen {\"u}ber die Entwicklung asiatischer Gletscher ber{\"u}cksichtigt werden.

In the preferred countries of destination (Israel, the United States and Germany) they are well-known for cultural self-assertion, strong social upward mobility and manifold forms of self organisation and empowerment. Using Suzanne Kellers sociological model of "Strategic Elites", it easily becomes clear that a huge share of the Russian Jewish Immigrants in Germany and Israel are part of various elites due to their qualification and high positions in the FSU - first of all professional, cultural and intellectual elites ("Intelligentsija"). The study aimed to find out to what extent developments of cultural self-assertion, of local and transnational networking and of ethno-cultural empowerment are supported or even initiated by the immigrated (Russian Jewish) Elites. The empirical basis for this study have been 35 half-structured expert interviews with Russian Jews in both countries (Israel, Germany) - most of them scholars, artists, writers, journalists/publicists, teachers, engineers, social workers, students and politicians. The qualitative analysis of the interview material in Israel and Germany revealed that there are a lot of commonalities but also significant differences. It was obvious that almost all of the interview partners remained to be linked with Russian speaking networks and communities, irrespective of their success (or failure) in integration into the host societies. Many of them showed self-confidence with regard to the groups' amazing professional resources (70\% of the adults with academic degree), and the cultural, professional and political potential of the FSU immigrants was usually considered as equal to those of the host population(s). Thus, the immigrants' interest in direct societal participation and social acceptance was accordingly high. Assimilation was no option. For the Russian Jewish "sense of community" in Israel and Germany, Russian Language, Arts and general Russian culture have remained of key importance. The Immigrants do not feel an insuperable contradiction when feeling "Russian" in cultural terms, "Jewish" in ethnical terms and "Israeli" / "German" in national terms - in that a typical case of additive identity shaping what is also significant for the Elites of these Immigrants. Tendencies of ethno-cultural self organisation - which do not necessarily hinder impressing individual careers in the new surroundings - are more noticeable in Israel. Thus, a part of the Russian Jewish Elites has responded to social exclusion, discrimination or blocking by local population (and by local elites) with intense efforts to build (Russian Jewish) Associations, Media, Educational Institutions and even Political Parties. All in all, the results of this study do very much contradict popular stereotypes of the Russian Jewish Immigrant as a pragmatic, passive "Homo Sovieticus". Among the Interview Partners in this study, civil-societal commitment was not the exception but rather the rule. Traditional activities of the early, legendary Russian „Intelligentsija" were marked by smooth transitions from arts, education and societal/political commitment. There seem to be certain continuities of this self-demand in some of the Russian Jewish groups in Israel. Though, nothing comparable could be drawn from the Interviews with the Immigrants in Germany.

For NGC 7469, we include optical spectroscopy from VLT/UVES. In both sight lines, the MS is detected in low-ion (O I, C II, C III, Si II, Si III, Al II, Ca II) and high-ion (O VI, C IV, Si IV) absorption. Toward NGC 7469, we measure an MS oxygen abundance [O/H](MS) = [O I/ H I]= -1.00 +/- 0.05(stat) +/- 0.08(syst), supporting the view that the Stream originates in the Small Magellanic Cloud rather than the Large Magellanic Cloud. We use CLOUDY to model the low-ion phase of the Stream as a photoionized plasma using the observed Si III/Si II and C III/C II ratios. Toward Mrk 335, this yields an ionization parameter between log U= -3.45 and -3.15, a gas density log (n(H)/cm(-3)) between-2.51 and -2.21, and a hydrogen ionization fraction of 98.9\%- 99.5\%. Toward NGC 7469, we derive sub-solar abundance ratios for [Si/O], [Fe/O], and [Al/O], indicating the presence of dust in the MS. The high-ion column densities are too large to be explained by photoionization, but also cannot be explained by a single-temperature collisional ionization model (equilibrium or non-equilibrium). This suggests that the high-ion plasma is multi-phase, with an Si IV region, a hotter O VI region, and C IV potentially contributing to each. Summing over the low-ion and high-ion phases, we derive conservative lower limits on the ratio N(total H II)/N(H I) of greater than or similar to 19 toward NGC 7469 and greater than or similar to 330 toward Mrk 335, showing that along these two directions the vast majority of the Stream has been ionized. The presence of warm-hot plasma together with the small-scale structure observed at 21 cm provides evidence for an evaporative interaction with the hot Galactic corona. This scenario, predicted by hydrodynamical simulations, suggests that the fate of the MS will be to replenish the Galactic corona with new plasma, rather than to bring neutral fuel to the disk.}, language = {en} } @book{OPUS4-4643, title = {Dritter Deutscher IPv6 Gipfel 2010}, editor = {Meinel, Christoph and Sack, Harald}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-092-2}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-46134}, publisher = {Universit{\"a}t Potsdam}, pages = {112}, year = {2010}, abstract = {Am 24. und 25.

The observed. - ray fraction of the required UHECR energy is even smaller if the source spectrum is softer than E-2. The AMANDA II limits rule out such a GRB origin for UHECRs if much more than 10(-2) of the cosmic-ray energy goes into neutrinos that are within, and simultaneous with, the gamma-ray beam. It is suggested that "orphan" neutrinos out of the gamma-ray beam might be identifiable via orphan afterglow or other wide angle signatures of GRBs in lieu of coincidence with prompt gamma-rays, and it is recommended that feasible single neutrino trigger criteria be established to search for such coincidences.}, language = {en} } @article{HerbertHerbertPollatosetal.2010, author = {Herbert, Beate M. and Herbert, Cornelia and Pollatos, Olga and Weimer, Katja and Sauer, Helene and Enck, Paul and Zipfel, Stephan}, title = {Effects of short-term food deprivation on interoceptive awareness, feelings and autonomic cardiac activity : implications for eating disorders}, issn = {0048-5772}, doi = {10.1111/j.1469-8986.2010.01111.x}, year = {2010}, abstract = {Poster session abstracts.

This spectral peak is closely related to the recurrence pattern of Dansgaard-Oeschger (DO) events. In previous studies a red noise random process, more precisely a first-order autoregressive (AR1) process, was used to evaluate the statistical significance of this peak, with a reported significance of more than 99\%. Here we use a simple mechanistic two-state model of DO events, which itself was derived from a much more sophisticated ocean-atmosphere model of intermediate complexity, to numerically evaluate the spectral properties of random (i.e., solely noise-driven) events. This way we find that the power spectral density of random DO events differs fundamentally from a simple red noise random process. These results question the applicability of linear spectral analysis for estimating the statistical significance of highly non-linear processes such as DO events. More precisely, to enhance our scientific understanding about the trigger of DO events, we must not consider simple "straw men" as, for example, the AR1 random process, but rather test against realistic alternative descriptions.}, language = {en} } @article{BreitenbachAdkinsMeyeretal.2010, author = {Breitenbach, Sebastian Franz Martin and Adkins, Jess F. and Meyer, Hanno and Marwan, Norbert and Kumar, Kanikicharla Krishna and Haug, Gerald H.}, title = {Strong influence of water vapor source dynamics on stable isotopes in precipitation observed in Southern Meghalaya, NE India}, issn = {0012-821X}, doi = {10.1016/j.epsl.2010.01.038}, year = {2010}, abstract = {To calibrate delta O-18 time-series from speleothems in the eastern Indian summer monsoon (ISM) region of India, and to understand the moisture regime over the northern Bay of Bengal (BoB) we analyze the delta O-18 and delta D of rainwater, collected in 2007 and 2008 near Cherrapunji, India. delta D values range from + 18.5 parts per thousand to 144.4 parts per thousand, while delta O-18 varies between +0.8 parts per thousand and 18.8 parts per thousand. The Local Meteoric Water Line (LMWL) is found to be indistinguishable from the Global Meteoric Water Line (GMWL). Late ISM (September-October) rainfall exhibits lowest delta O-18 and delta D values, with little relationship to the local precipitation amount. There is a trend to lighter isotope values over the course of the ISM, but it does not correlate with the patterns of temperature and rainfall amount delta O-18 and delta D time-series have to be interpreted with caution in terms of the 'amount effect' in this subtropical region. We find that the temporal trend in delta O-18 reflects increasing transport distance during the ISM, isotopic changes in the northern BoB surface waters during late ISM, and vapor re-equilibration with rain droplets. Using an isotope box model for surface ocean waters, we quantify the potential influence of river runoff on the isotopic composition of the seasonal freshwater plume in the northern BoB. Temporal variations in this source can contribute up to 25\% of the observed changes in stable isotopes of precipitation in NE India. To delineate other moisture sources, we use backward trajectory computations and find a strong correlation between source region and isotopic composition. Palaeoclimatic stable isotope time-series from northeast Indian speleothems likely reflect changes in moisture source and transport pathway, as well as the isotopic composition of the BoB surface water, all of which in turn reflect ISM strength. Stalagmite records from the region can therefore be interpreted as integrated measures of the ISM strength.}, language = {en} } @article{StreichBeckenRitter2010, author = {Streich, Rita and Becken, Michael and Ritter, Oliver}, title = {Imaging of CO2 storage sites, geothermal reservoirs, and gas shales using controlled-source magnetotellurics : modeling studies}, issn = {0009-2819}, doi = {10.1016/j.chemer.2010.05.004}, year = {2010}, abstract = {To balance the steady decrease of conventional hydrocarbon resources, increased utilization of unconventional and new energy resources, such as shale gas and geothermal energy, is required. Also, the geological sequestration of carbon dioxide is being considered as a technology that may temporarily mitigate the effects of CO2 emission. Sites suitable for shale gas production, geothermal exploration, or CO2 sequestration are commonly characterized by electrical resistivities distinctly different from those of the surrounding rocks. Therefore, electromagnetic methods can be viable tools to help identify target sites suitable for exploration, and to monitor reservoirs during energy production or CO2 injection. Among the wide variety of electromagnetic methods available, controlled-source magnetotelluric (CSMT) may be particularly suitable because of (i) its ability to resolve both electrically resistive and conductive structures, (ii) controlled sources offering noise control and thus facilitating surveys in populated regions, and (iii) the potential of penetration throughout the depth range accessible by drilling. Nevertheless, CSMT has not yet been widely employed because of logistical challenges of field operations and the requirement of complex and highly computer-intensive data processing. With these difficulties gradually being mitigated by recent technological developments, CSMT may now be reconsidered as an exploration tool. Here, we investigate by 1D and 3D numerical simulations the feasibility of detecting gas shales and identifying sites eligible for geothermal exploration or CO2 sequestration from CSMT data. We consider surface-to-surface, borehole-to-surface, and cross-hole configurations of the sources and receivers. Results and conclusions on the detectability of the targets of interest are presented for various exploration and monitoring scenarios, which are roughly representative of the geological setting of the North German Basin.}, language = {en} }
