    In:  Protokoll über das 26. Schmucker-Weidelt-Kolloquium für Elektromagnetische Tiefenforschung : Dassel 21.-25. September 2015
    Publication Date: 2020-02-12
    Description: In der Geoelektromagnetik werden oft großflächige Quellen, beispielsweise Leiterschleifen, näherungsweise als Punktquellen aufgefasst. Diese Annahme ist jedoch nur für hinreichend große Entfernungen zwischen Quelle und Messpunkt zulässig. Da die Messung mit relativ kleinen Spulen durchgeführt werden, die Sendespulen aber bis zu 10 000m2 Spulenfläche aufweisen, liegt es nahe, das Reziprozitätsprinzip auszunutzen, um Sender und Empfänger zu vertauschen. So wird das Feld eines Sendedipols am Ort des eigentlichen Empfängers genutzt, um über die Lösung dieses Dipols am Ort des eigentlichen Senders zu integrieren. Die Integrationsfläche entspricht dabei der Fläche der eigentlichen Sendeschleife. Dabei kann die Lösung des Dipols entweder analytisch über homogenen oder geschichteten Leitfähigkeitsmodellen oder numerisch über beliebigen Leitfähigkeitsverteilungen berechnet werden. Um den Einfluss der Spulengeometrie abzuschätzen, gen¨ugt meist die Auswertung der analytischen L¨osung. Die numerische Integration geschieht dabei durch eine zweidimensionale Gaußquadratur. Eine Konvergenzstudie zeigt die Abhängigkeit der Genauigkeit dieses Ansatzes von der Knotenzahl der Gaußquadratur in Verbindung mit ausgew¨ahlten Entfernungen zwischen Senderzentrum und Messpunkt.

    Description: Subduction earthquakes are the most powerful naturally occurring terrestrial processes often resulting in catastrophic fatality counts and decimation of human infrastructure. Over the past decades, great efforts have been undertaken to improve the understanding of the subduction earthquake physics. The Integrated Plate Boundary Observatory in Chile (IPOC) is a multi-instrument network installed in 2007 in the Northern Chile Seismic Gap, where a large magnitude earthquake was expected soon. On April 1st 2014, a portion of the IPOC-monitored region broke, producing the Mw 8.1 Iquique earthquake. In the year leading up to this event, IPOC’s instruments captured some unusual transient seismic and geodetic signals, resulting in a unique dataset recording the preparatory phase of a large earthquake. We combined IPOC data with satellite radar interferometry (InSAR) data to analyze not only the earthquake itself but also the interseismic phase and a detailed foreshock series before the main event. We found that the earthquake ruptured a zone on the plate interface that was highly locked before the earthquake. Additionally, we were able to characterize the aseismic (silent) slip that occurred in the two weeks leading up to the event by combining seismic and geodetic data. Application of these analyses in real-time might enable geoscientists to identify runaway processes that can precede large subduction earthquakes.

    Description: Rupture processes show strong similarities on broad spatial scales suggesting that in parts the governing physics for microcrack formation in the laboratory or a large earthquake along a tectonic plate boundary are the same. We discuss examples ranging from rock deformation experiments in the laboratory under controlled boundary conditions, induced seismicity in mines and geological reservoirs to natural earthquakes posing tremendous seismic hazard to population centers. We describe fundamental relations for the entire bandwidth of rupture processes involving fractures, faults and shear zones and their seismic characteristics such as b-value or seismic source properties. Laboratory tests on small-scale rock samples allow studying aspects of processes that control earthquake nucleation and rupture propagation. However, up-scaling of laboratory results to the field scale requires that dominant deformation processes remain the same on vastly different scales, and that potential effects of changing kinematic boundary conditions may successfully be accounted for by appropriate constitutive equations. Our approach shows that constitutive models capturing fundamental physical processes on the laboratory scale may be successfully applied to improve process understanding of deformation on the field scale with the potential to improve seismic hazard estimation.

    Description: Seismology is often associated with the investigation of earthquake processes and indeed this is a very important target of the science. However, seismology is also the primary means by which we can obtain images of the internal structure of the Earth on all scales, ranging from the deep interior, i.e. the Earth’s core and lower mantle over the mantle lithosphere and crust, the scale at which plate tectonics ‘happens’ all the way to the unconsolidated material in the near-surface. Seismology uses earthquakes and artificial sources as signal generators but also the ambient background wavefield, previously considered to be merely noise. Methodological and instrumental innovations have allowed ever more detailed investigations of the earthquake process and the seismic structure, and opened up new targets such as as the monitoring of geomorphological events and investigations of the time-dependency of seismic structure. Finally seismology is not restricted to waveform analysis and the instrumental period but draws on historical data and, in the field of paleoseismology, geological markers to constrain seismic activity in the pre-instrumental past. Direct societal benefits from seismology accrue for example from improved seismic hazard estimates and early-warning technologies in the area of natural hazards, from improved recovery and usage of natural resources, including geothermal energy as a sustainable energy source and much more, e.g. the possibility to monitor and thus enforce compliance with the nuclear test ban treaty.

    Description: Deep seismic sounding provides important information on the seismic structure of the crust. Seismic experiments make use of controlled sources (explosions, Vibroseis) or natural sources (earthquakes, ambient noise), or combinations of both types. Seismic velocities are derived from modelling or tomographic inversion of diving waves and refractions. Particularly the combined interpretation of compressional and shear velocities allows for insight into the lithological structure of the crust. Seismic reflectivity is derived from imaging of waves reflected at geological boundaries. Typical patterns of crustal reflectivity are observed for specific tectonic settings. Case studies are shown from two studies at plate boundary systems. (1) The old plate boundary at the Namibian margin was formed by Cretaceous continental rifting and its interplay with the activities of the Tristan da Cunha mantle plume. Traces of intensive magmatic overprinting of the crust at the landfall region of Walvis Ridge can be seen in the derived velocity model and also in the reflectivity image. (2) The Dead Sea transform marks the active boundary between the African and Arabian plates. The Dead Sea basin was formed by pull-apart in response to step-over of the fault system. Results from tomography reveal a deep asymmetric basin structure. An anomalous body was found under the basin, between 13 and 18 km depth, which is interpreted as pre-basin sediments. Our results are supported by the distribution of earthquakes. The results provide new constraints for the modeling of plate boundary processes.

    Description: The nucleation of earthquakes and their seismic waves cannot be predicted in a deterministic sense. However probabilistic hazard and risk estimations can be conducted which help to increase the preparedness and reduce the vulnerability of societies. Those estimations are based on the rapidly growing number of empirical earthquake data recorded by seismic networks or known from historical or geological studies, which show that earthquakes are not randomly occurring. They typically occur clustered in space and time with specific characteristics such as the Gutenberg-Richter law for the frequency-magnitude distribution. Seismicity models have to account for earthquake interactions to avoid erroneous estimations of the activity level and spatial distribution of future activity. Additionally, the vulnerability of societies is changing with with time, because of the dynamic reconstruction and growth of cities in earthquake-prone regions. Thus new sophisticated models, strategies, and methods have to be developed and tested for all components of the earthquake risk chain to improve our probabilistic hazard and risk estimations.

    Description: Diese Ausgabe des GFZ-Journals „System Erde“ wurde im Dezember 2016 produziert und erscheint im Januar 2017. Das ist der Monat, in dem das Deutsche GeoForschungsZentrum seinen 25. Geburtstag feiert. Der Schwerpunkt Südamerika ist dabei durchaus passend, denn die Forscherinnen und Forscher des GFZ arbeiten dort seit der Gründung des Zentrums. Die Südpazifikküste mit den großen Subduktionsbeben, die Anden mit ihren Vulkanen und all die geologischen Prozesse, die in der Region sichtbar werden, sind wie die Seiten eines Lehrbuchs der Geologie – wenn man sie denn zu entziffern weiß. Selbst die so genannten passiven Kontinentalränder an den Küsten des Südatlantiks bieten uns tiefe Einblicke in die Erdgeschichte; sie sind Geoarchive erster Ordnung. Hinzu kommt, dass sie Lagerstätten für Rohstoffe bergen.

    Description: Seismic interferometry is a methodology to recover the signals of waves propagating between seismic stations from records of random wavefields such as the ambient seismic noise or the coda of an earthquake. Teleseismic body waves excited by a very deep earthquake close to Kamchatka are investigated to unveil the composition of the teleseismic wavefield at long propagation times which is key to understand how teleseismic waves can be reconstructed by seismic interferometry. Waves at high frequencies around 1s period are shown to be scattered strongly in the Earth crust where they are quickly attenuated. At low periods, seismic waves circle the Earth for many hours as surface waves with clear arrivals of the different orders. At intermediate periods around 40s waves still propagate for several hours but individual arrivals cannot be identified in the data any more – indicating a randomization process. It is shown here that to a large extent this randomization is due to the interaction with the Earth’s 1D structure that does not alter the azimuthal distribution of the wavefield. Even after 8 h the seismic energy propagates dominantly along the great circle and the mean free time of the azimuthal randomization is estimated to 10 h. This means that the recovery of the teleseismic wavefield by seismic interferometry is strongly dependent on the distribution of ambient sources. For a successful application of seismic interferometry sources need to be present at suitable distances on the great circle connecting the stations.

    Description: The warm water geothermal reservoir below the village of Waiwera in New Zealand has been known by the native Maori for centuries. Development by the European immigrants began in 1863. Until the year 1969, the warm water flowing from all drilled wells was artesian. Due to overproduction, water up to 50 °C now needs to be pumped to surface. Further, between 1975 and 1976, all warm water seeps on the beach of Waiwera ran dry. Within the context of sustainable water management, hydrogeological models must be developed as part of a management plan. Approaches of varying complexity have been set-up and applied since the 1980s. However, none of the models directly provide all results required for optimal water management. Answers are given simply to parts of the questions, nonetheless improving resource management of the geothermal reservoir.
    Description: Das geothermische Warmwasserreservoir unterhalb der Kleinstadt Waiwera in Neuseeland ist seit vielen Jahrhunderten bei den Ureinwohnern, den Maori, bekannt. Die Nutzung durch die europäischen Einwanderer begann 1863. Bis in das Jahr 1969 waren die bis dahin abgeteuften Förderbohrungen für das warme Wasser artesisch. Ausgelöst durch eine Überproduktion muss das bis zu 50 °C heiße Wasser heute mit Pumpen gefördert werden. In den Jahren 1975 und 1976 kam es zusätzlich zum Versiegen der Warmwasserquellen am Strand von Waiwera. Im Rahmen einer nachhaltigen Wasserbewirtschaftung ist es notwendig, hydrogeologische Modelle einzusetzen. Unterschiedlich komplexe Ansätze wurden seit den 1980er- Jahren umgesetzt. Keines der Modelle liefert allerdings direkt alle für dasWassermanagement benötigten Ergebnisse. Es werden jeweils Antworten auf Teilaspekte gegeben, die das Ressourcenmanagement des geothermischen Reservoirs verbessern.

    Description: The Atacama Fault System (AFS) is an active trench-parallel fault system, located in the forearc of N-Chile directly above the subduction zone interface. Due to its well-exposed position in the hyper arid forearc of N-Chile it is the perfect target to investigate the interaction between the deformation cycle in the overriding forearc and the subduction zone seismic cycle of the underlying megathrust. Although the AFS and large parts of the upper crust are devoid of any noteworthy seismicity or historically documented earthquakes, at least three M=7 earthquakes in the past 10 ky have been documented in the paleoseismological record, demonstrating the potential of large events in the future. We apply a two-fold approach to explore fault activation and reactivation patterns through time and to investigate the triggering potential of upper crustal faults. 1) A new methodology using high-resolution topographic data allows us to investigate the number of past earthquakes for any given segment of the fault system as well as the amount of vertical displacement of the last increment. This provides us with a detailed dataset of past earthquake rupture of upper plate faults which is potentially linked to large subduction zone earthquakes. 2) The IPOC Creepmeter array provides us with high-resolution time series of fault displacement accumulation for eleven stations along the four most active branches of the AFS.

    Description: In news reports we are accustomed to see earthquakes symbolised with a dot or star on a map and associated with a magnitude, the bigger the scarier. For at least moderately sized earthquakes seismologists additionally have been routinely determining the type of rupture just from observing the pattern of radiated seismic energy. In reality earthquakes do not occur as a point but rupture a fault plane. For small earthquakes this distinction can be neglected but for the largest earthquakes the rupture plane can extend for hundreds of kilometres, and the actual rupture propagation begins to have a strong influence on the hazard that the earthquake presents – whether the rupture proceeds to the north or the south and how deep and shallow it reaches determines which cities will be hit the hardest, whether shaking is moderate or intense, and whether a sizeable tsunami is triggered. The explosion of the availability of ground-, ocean- and space-based observation technologies in the last decade has allowed seismologists to map the rupture process in unprecedented detail even for challenging subduction zone earthquakes. The same technology can be used to observe potential precursory processes and the postseismic relaxation by which the earth regains its equilibrium following the disturbance that a great earthquake represents. Focussing on the Mw 8.1 Iquique earthquake in northern Chile on April 1, 2014, we will discuss the state-of-the-art in monitoring great earthquakes and their aftermath.

    Description: Significant scientific findings are often directly related to innovations in measurement technology. For investigating the Earth’s interior the invention of the seismography played the most important role. Starting with the first seismograph suitable for scientific investigations by Ewing, Gray and Milne in the 1870s and its improvement by Wiechert around 1900, seismic instrumentation was available in the beginning of the last century to reveal the layered structure of our planet. Since then, instruments were steadily improved, and controlled source experiments and seismic networks significantly contribute today to our understanding of the Earth’s structure and the ongoing dynamic processes as well as to the exploration of resources as oil, gas, water and minerals. At the GFZ German Research Centre for Geosciences we work on technical innovations and apply them in experiments around the world and at a variety of scales. We develop highly portable, low-cost, high-performance seismic data recording systems, which are designed to be used in “large-N” array configurations (〉1000 receivers) and on the sea floor (shallow water). Distributed accoustic sensors (DAS) based on fibre-optic cables allow extremely dense sampling of the seismic wavefields. Seismic sources and receivers integrated in borehole tools illuminate in high-resolution the subsurface during drilling operations (Seismic prediction while drilling, SPWD).

    Description: Das Wissen um die lokale Struktur von Seltenen Erden Elementen (SEE) in silikatischen und aluminosilikatischen Schmelzen ist von fundamentalem Interesse für die Geochemie der magmatischen Prozesse, speziell wenn es um ein umfassendes Verständnis der Verteilungsprozesse von SEE in magmatischen Systemen geht. Es ist allgemein akzeptiert, dass die SEE-Verteilungsprozesse von Temperatur, Druck, Sauerstofffugazität (im Fall von polyvalenten Kationen) und der Kristallchemie kontrolliert werden. Allerdings ist wenig über den Einfluss der Schmelzzusammensetzung selbst bekannt. Ziel dieser Arbeit ist, eine Beziehung zwischen der Variation der SEE-Verteilung mit der Schmelzzusammensetzung und der Koordinationschemie dieser SEE in der Schmelze zu schaffen.
    Description: Knowledge of the local structure around rare earth elements (REE) in silicate and aluminosilicate melts is of fundamental interest for the geochemistry of magmatic processes, particularly for comprehensive understanding of the partitioning processes of REE in magmatic systems. It is generally accepted that mineral-melt partitioning of REE’s is controlled by temperature, pressure, oxygen fugacity (in case of polyvalent cations) and crystal chemistry but less is known about the influence of the melt composition. The aim of this thesis is to establish a relationship between the variation of the REE distribution with the melt composition and the coordination chemistry of this REE in the melt.

    Description: Volcanic activity involves different processes on different scales at depth and at the surface. Many of them generate seismic signals, ranging from tiny, earthquake-like signals to increased continuous vibrations to significant ground motion events before and during volcanic eruptions. A range of modern tools of volcano seismology is nowadays used to monitor changes in the volcanic activity and volcanic unrest. Additionally, advanced seismology is able to image the deep volcanic structures at high resolution and to map the depth and size of magmatic reservoirs beneath volcanoes. Although seismology is a key technology for volcano research and the assessment of volcanic hazard, novel concepts of volcano monitoring combine seismology with different types of multi-parameter sensors to characterize the processes accompanying volcanic unrest. GFZ is developing advanced approaches for volcano monitoring and volcano modeling involving a broad scale of instruments and disciplines. The article focuses mainly on two examples from volcanoes in South America and Iceland showing how large magmatic reservoirs are slowly filled over periods of decades and abruptly depleted over periods of months during volcanic eruptions.

    Description: Sedimentary basins represent geological archives. Accordingly, 3D basin models that integrate geological and geophysical observations can be used to reproduce not only their present-day structural configuration and distribution of physical properties, but also their evolution including the subsidence history. For example, the thickness of deposited sediments reflects the amount of subsidence caused by the sediment load. The corresponding load-dependent vertical movements (called isostatic subsidence) can be sequentially subtracted from the total subsidence in order to reconstruct past depth configurations. Another aspect of basin subsidence is caused by thermal processes that can also be approximated by studying the present-day basin configuration. If the basin formation is related to lithospheric stretching and thinning, it initially involves a thermal disturbance due to which the geothermal gradient is increased by an amount depending on the observed strain. After stretching has ceased, the lithosphere starts cooling down and approaches a thermal equilibrium. This cooling process is accompanied by an increase in rock density and related thermal subsidence, which can also be assessed. By calculating the two subsidence components for certain stratigraphic intervals, the corresponding temporal changes in water depths (paleobathymetries) can be reconstructed for our understanding of subsidence dynamics. This research methodology was applied to the conjugate passive continental margins of Africa and Argentina in order to analyse and compare the evolution of sedimentary basins after the formation of the South Atlantic. This study mainly focussed on the Argentinian Colorado Basin because of its complex evolution and economic resource potential.

    Description: Very long baseline interferometry (VLBI) is one of the fundamental space geodetic techniques. Important goals for the next generation of VLBI technology are continuous operations as well as automated data processing. For this reason, it is necessary to introduce real time capable parameter estimation algorithms, such as Kalman filters, to VLBI data analysis. In this study, such a filter was implemented in the VLBI software VieVS@GFZ, and several aspects related to VLBI data processing were investigated. Within the corresponding module VIE_KAL it is possible, for example, to estimate all parameters important in VLBI analysis, adapt their stochastic models, flexibly define the datum, integrate external data, as well as extract datum free normal equations. The foci of the investigations were on the effects of the troposphere, the most important error source in VLBI analysis, and on the determination of station positions, which are of great importance in geodesy. For the stochastic model of the tropospheric delays, station- and timedependent differences were considered. In comparisons with tropospheric parameters from GNSS, water vapor radiometers and numerical weather models, the Kalman filter solution yielded 5 to 15% smaller differences than a least squares solution based on the same models and VLBI data. Also in the case of estimated station coordinates, the Kalman filter solution exhibited better baseline length and station coordinate repeatabilities. The application of station-based process noise led to additional improvements. Furthermore, the Kalman filter was used to estimate subdaily station coordinate variations caused by tidal and loading effects. Finally, the findings were used to determine Kalman-filter-based global terrestrial reference frames (TRFs). For the stochastic model of the coordinate variations of particular stations, loading deformation time series were utilized. The non-deterministic approach of the Kalman filter allowed the consideration of non-linear station movement, for example, due to irregular seasonal effects or post-seismic deformations. In comparisons with a VLBI TRF solution from a classical adjustment and ITRF2008, a good agreement in terms of transformation parameters and station velocities was achieved. The findings from testing different options related to the parameterization and to the stochastic model will help to improve future reference frames.

    Description: Seismic hazard assessments can only be as good as the historical past is known. Therefore, reliable seismicity records have to be extended back into history as far as possible. Hence, historical seismological investigation is of utmost importance in order to achieve long-term earthquake catalogue data of high quality. This basic research has been performed at the GFZ German Research Centre for Geosciences as a multidisciplinary approach of seismologists and historians for many years. Seismic activity before the installation of the first seismographs in the beginning of the 20th century can only be reconstructed based on written sources For Central Europe, these documents date back up to the middle of the 8th century. The historical information for each earthquake has to be source-critically analyzed and transferred into parameterized information, which is then catalogued. During the long tradition of collecting past seismic information starting more than a century ago, many mistakes were made, like duplications of events, misinterpreted strength, location and wrong dating of earthquakes, which could be identified by our investigation. We show exemplarily how these uncertainties can be mitigated. Historical passing on of information is transferred to modern seismicity parameters by applying historic-critical methods. Thus, we are able to acquire better and more reliable long-term data for historical earthquake catalogues and for trustworthy long-term seismic hazard assessments.

    Description: To this date, the question of why and how a plateau-type orogen formed with massive crustal thickening at the leading edge of western South America remains one of the hotly debated issues in geodynamics. During the Cenozoic, the Altiplano and Puna plateau of the Central Andes developed during continuous subduction of the oceanic Nazca plate in a convergent continental margin setting – a situation that is unique along the 60 000 km of convergent margins around the globe. The key challenge is to understand why a first-order mechanical instability of the later plateau extent developed along the central portion of the leading edge of South America only, as well as why and how this feature developed only during the Cenozoic, although the cycle of Andean subduction had been ongoing since at least the Jurassic. Although the widespread presence of partial melts or metamorphic fluids at mid-crustal level has been suggested to indicate upper plate weakening from heating and partial melting, it is recently found that upper plate strain weakening at lithospheric scale plays a significantly larger role. This first order control is tuned by factors affecting the strength balance between the upper plate lithosphere and the plate interface of the Nazca and South American plates such as variations in trenchward sediment flux affecting plate interface coupling and slab rollback or the role of inherited structures. Late initiation of orogeny in the Eocene, however, and its sustained action over tens of million years is now found to be related to the penetration of the slab into the lower mantle around 50 Ma ago, producing a slowdown of the lateral slab migration (‚slab anchoring’), and dragging the upper plate against the subduction zone by large-scale return flow. The combination of these parameters was highly uncommon during the Phanerozoic leading to very few plateau style orogens at convergent margins like the Cenozoic Central Andes in South America or the Laramide North American Cordillera.

    Description: The Earth’s surface is constantly changing as material is redistributed by processes like slope failures, debris flows and floods. Although this is a natural part of landscape evolution, we perceive many of these processes as hazards. Especially during their extreme manifestations, they can cause significant damage and even injury and loss of life. The process understanding that is necessary for the safe keeping of the environment that we live in can be obtained by acute observation. Seismic measurements provide distinct advantages over traditional methods. Within a sensor network, many important processes at the Earth’s surface can be observed and identified, along with their meteorological drivers. Further, seismic networks make it possible to monitor the entire landscape without the need of a prior choice of location. In this way, nearly complete event catalogues can be obtained and the interaction of different processes can be studied. The potential of seismic observations of Earth surface processes is illustrated with an example from the Illgraben, Switzerland. There, a two-way interaction between rock slope failures and debris flows was observed during a summer thunderstorm.

    Description: The Integrated Plate Boundary Observatory Chile (IPOC) in northern Chile has been monitoring the largest seismic gap along the South American subduction zone for 10 years. When IPOC was initiated, it has been 130 years the last great earthquake in the region had occurred. And since then the Iquique gap had been accumulating a slip deficit along a 〉500 km segment of the plate boundary. Since IPOC’s inception two large events, the 2007 M 7.7 Tocopilla and the M 8.1 2014 Iquique earthquakes, have broken parts of the gap. Both events were well recorded by IPOC, produce valuable data and advance our understanding of the subduction megathrust earthquake cycle. Last year, the Helmholtz Centre for Ocean Research Kiel (GEOMAR) has been extending IPOC with the GeoSEA ocean bottom observatory. In this ambitious project deformation will be measured where it cannot be picked up by land-based instruments, i. e. far offshore near the subduction trench. This will open the crucial updip section of the subduction plate boundary to research. IPOC has thus demonstrated the necessity of long-term monitoring to observe slow or rare events, but also that tenacity and patience pay off.

    Description: The South American continent as we know it formed during the break-up of West Gondwana between 150 and 110 million years ago, when the South Atlantic Rift system evolved into the South Atlantic ocean. Using state-of-the-art global tectonic reconstructions in conjunction with numerical and analytical modelling, we investigate the geodynamics of rift systems as they evolve into an ocean basin. We find that rifts initially stretch very slowly along the future splitting zone, but then move apart very quickly before the onset of rupture. In case of the split between South America and Africa, the divergence rate increased from initially 5 to 7 millimetres per year to over 40 millimetres per year within few million years. Intriguingly, abrupt rift acceleration did not only occur during the splitting of West Gondwana, but also during the separation of Australia and Antarctica, North America and Greenland, Africa and South America, in the North Atlantic or the South China Sea. We elucidate the underlying process by reproducing the rapid transition from slow to fast extension using analytical and numerical modelling with constant force boundary conditions. The mechanical models suggest that the two-phase velocity behaviour is caused by a rift-intrinsic strength–velocity feedback similar to a rope that snaps when pulled apart. This mechanism provides an explanation for several previously unexplained rapid absolute plate motion changes, offering new insights into the balance of plate driving forces through time.

    Description: Die quantitative Landschaftsökologie beschäftigt sich mit der räumlichen Abgrenzung von Landschaftsstrukturen auf unterschiedlichen räumlichen Skalen sowie mit den dort beobachtbaren Wechselwirkungen zwischen der belebten und unbelebten Umwelt. Obwohl die Landschaftsökologie in ihrem Ursprung eine terrestrisch orientierte Fachdisziplin ist, sollten deren Methoden auch auf den aquatischen Bereich übertragbar sein, denn auch hier existieren in Abhängigkeit der topografischen, hydrografischen und sedimentologischen Voraussetzungen in sich homogene Lebensraumstrukturen, die man als Landschaften auffassen kann. Ein sich entwickelnder Bedarf an geeigneten planerischen Methoden und Konzepten im marinen Umweltmonitoring ergibt sich aus aktuellem Anlass: Am 17. Juni 2008 wurde die Meeresstrategie-Rahmenrichtlinie (MSRL) durch Beschluss des Europäischen Parlaments und des Rates in der Europäischen Union eingeführt. Die MSRL zielt auf eine umweltgerechte Bewirtschaftung der Meere ab und strebt die Erlangung eines Guten Umweltzustands in den europäischen Meeren bis 2020 an. Mit der Richtlinie erhöhen sich die Anforderungen an die Planung und Überwachung des Zustands der marinen Gewässer in Europa. Neben einer Anfangsbewertung der Meeresgebiete der Mitgliedsstaaten sowie der darauf aufbauenden Festlegung des Guten Umweltzustands anhand abiotischer und biotischer Merkmale und von Umweltzielen sollen auch Maßnahmen zur Erreichung dieser Ziele umgesetzt werden. Der Erfolg dieser Maßnahmen soll durch eine Überwachung des Zustands der Meeresgebiete begleitet werden. Entsprechende Monitoring-Programme sollen eine laufende Bewertung des Umweltzustands anhand chemisch-physikalischer und biologischer Merkmale zulassen. Im Hinblick auf die Planung landschaftsökologisch repräsentativer, auf die Optimierung von Suffizienz- und Effizienzkriterien ausgerichteter Umweltmessnetze in der deutschen Nordsee widmet sich vorliegende Habilitationsschrift der Überprüfung der Übertragbarkeit zweier Methoden der quantitativen Landschaftsökologie in den marinen Raum am Beispiel der deutschen Nordsee. Neben der datenbasierten Ableitung landschaftsökologischer Raumgliederungen für den erweiterten Bereich der deutschen Nordsee mittels statistischer Methoden steht dabei die für die Erfassung des Landschaftshaushalts landschaftsökologisch repräsentative Planung stoffbezogener Umweltmessnetze im Mittelpunkt.
    Description: Quantitative landscape ecology is concerned with the regional classification of landscape structures on various spatial scales, including the here observed interactions between the biological and abiotic environment. Despite the fact that landscape ecology has originally been a terrestrial research field, its methods should be applicable to the aquatic environment. Depending on the prevailing topographical, hydrographical, and sedimentological conditions, homogeneous benthic habitat structures, which we may be referred to as landscapes, do exist here as well. A developing demand for adequate planning methods and concepts in the field of marine environmental monitoring ensues in the light of current events. On July 17, 2008 the Marine Strategy Framework Directive (MSFD) was introduced by a resolution of the European Parliament and the Council of the European Union. The MSFD is targeted on an environmentally sound management of European oceans and aims at achieving a Good Environmental Status (GES) for European marine waters by the year 2020. The directive increases marine planning requirements with respect to monitoring the condition of marine waters in Europe. Apart from an initial assessment of the marine areas of the member states and the ensuing determination of the GES with regard to biotic and abiotic characteristics, as well as the definition of environmental objectives, adequate measures to reach these goals shall also be implemented. The success of these measures is to be accompanied by monitoring activities with regard to the chemical, physical and biological parameters of the marine environment. The question of where to monitor is decided for and discussed within the German Marine Monitoring Programme of the federation and the federal states. Taking the extended area of the German North Sea as an example, the habilitation thesis here submitted focuses on verifying the transferability of two application areas of terrestrial quantitative landscape ecology to the marine environment in order to assist the planning of monitoring networks in Germany’s marine waters. Next to the data-based derivation of landscape ecoregionalizations by means of statistical methods, another focus is set on the landscape-ecologically representative planning of substance based environmental monitoring networks.

    Description: The paper presents results of multiproxy-investigations of a 3 m long sediment section from the Glowe Palaeolake, covering the period Pre-Bølling to the middle of the Preboreal. The Lateglacial and early Holocene landscape development comprising climate fluctuations, lake evolution, lake-level variations and vegetation history is reconstructed using pollen, diatom, macrofossil, molluscs as well as sedimentological and geochemical data based on 14C-dating. The palaeolake appeared due to the decay of the permafrost during the Bølling and developed in the Allerød into a 3–4 m deep, species-poor and macrophyte-rich stillwater. The submerse vegetation and fauna decreased during the Younger Dryas, but returned fast and with higher density in the Preboreal. Phases of cooler climate can be parallelized with the Gerzensee oscillation, the Younger Dryas and the Rammelbeek oscillation, which each are palynologically bipartite. In contrast, indications for the Older Dryas were only scarce. The cooler phases were characterized by intensified allochthonous clastic input into the lake. During the Younger Dryas the input was dominated by solifluction processes, while during the Allerød and the Preboreal predominantly fluvial processes occurred. The most significant changes in the palaeoecology of the lake were caused by the rapid warming at the onset of the Preboreal. During the phases of warmer climate the vegetation development was influenced by the vicinity to the Baltic Ice Lake, which caused – compared to more southerly regions – a delayed spread of Pinus. Also, the long term climate changes determined the alterations in the chemical sediment composition, the diatom flora and the macrophyte vegetation. Short term variations, which caused the closely spaced sediment layering mainly in the older part of the sediment section cannot be explained so far. The course of the outcropping stratigraphic units was used to construct a lake-level curve. It shows a rapid rise in the early Allerød and a subsequent slower rise until the highstand in the Younger Dryas. In the early Preboreal, a fast lake-level fall occurred, the palaeolake silted up and dried out in the middle of the Preboreal.

    Description: Das ehemalige Gaswerk liegt innerhalb der Stadt Neubrandenburg „Am Güterbahnhof“, umgeben von Altbausubstanz mit gewerblicher Nutzung und Wohnbebauung. Die Produktion von Stadtgas aus Steinkohle begann hier 1867. Eine Erweiterung erfolgte im Ersten Weltkrieg durch die Inbetriebnahme einer Wassergasanlage zur Streckung des Steinkohlengases, einer Benzolgewinnungsanlage und einer Sulfatfabrik. Im Zweiten Weltkrieg kam es zur Zerstörung der drei Gasbehälter und von Teilen der Bebauung. Nach 1945 wurde das Gaswerk mit einem Gasbehälter wieder aufgebaut. In den letzten Nutzungsjahren traten zahlreiche Havarien durch übergelaufene Teer- und Ammoniakgruben sowie durch verstopfte Leitungen auf. 1971 erfolgten die Stilllegung des Gaswerkes und ein teilweiser Rückbau der oberirdischen Anlagen.

    Description: Bei dem für die Eugen-Geinitz-Sicht in Usadel ausgewählten Findling (Fundort: vermutlich Kiesgrube Siedenbüssow) handelt es sich um ein seltenes monomiktes Konglomerat, dessen Herkunft – und damit auch sein Bildungsalter – bisher nicht genau bestimmt werden kann. In einer sandigen bis feinkiesigen, rötlich-violetten Matrix befinden sich zahlreiche helle, mäßig gerundete Gesteinsbruchstücke bis 12 cm Größe aus kristallinem Quarz (Gangquarz). Konglomerate mit einer ähnlichen Zusammensetzung sind als lokale Einschaltungen in mesoproterozoischen Sandsteinen und Grauwacken an der Hohen Küste in Nordschweden bekannt und möglicherweise als isolierte Vorkommen im gesamten Verbreitungsgebiet jotnischer Rotsedimente zu finden. Aufgrund der Zusammensetzung und des relativ geringen Verfestigungsgrades kann aber auch eine Zuordnung zur klastischen Abfolge der jüngstproterozoisch-unterkambrischen Nexö-Formation Bornholms nicht völlig ausgeschlossen werden, deren basale Schichten ebenfalls unter terrestrischen, oxidativen Bedingungen abgelagert wurden.

Anhand aktueller Nachweise mit dem Autokescher wird die Verbreitung und Häufigkeit einiger Arten in MV neu bewertet. Zwei Arten sind neu für die Fauna des Bundeslandes: 〈i〉Cousya longitarsis〈/i〉 (Thomson, 1867) and 〈i〉Philonthus ebeninus〈/i〉 (Gravenhorst, 1802). Xerotherme Standorte, sandige Ufer von Fließgewässern und Salzwiesen sind in MV selten bzw. werden oftmals massiv beeinträchtigt. Diese Habitate beherbergen jedoch eine Vielzahl ökologisch anspruchsvoller Arten und sollten deshalb besonders geschützt werden.

    Description: This article presents investigations of a diverse landscape in the young moraine area of southeastern Schleswig-Holstein (Stormarn county). The northern part of the study area represents a large basin, possibly a glacier basin influenced by glaciofluvial meltwaters or by dead ice. Organic sedimentation occurred in this basin from the Late-glacial (Bölling/Alleröd interstadial complex), followed by a longer lake phase and the growth of a fen after c. 5.000 14C a B.P. The central area of the basin was formed as ice-disintegration landscape – including kames, eskers and esker-like features. Ring-like glaciofluvial landform structures are interpreted as subcircular eskers. Kettle bogs developed in the centres of these landforms from c. 5.000 14C a BP (Atlantic/Subboreal) onwards. The southern and south-eastern part of the study area represents a smoothed moraine zone, that includes a glaciotectonically influenced Saalian core of till, sand and glacilacustrine sediment. Parallel aligned gullies were predominantly formed as tunnel valleys. Some parts of the channels are infilled with glaciolacustrine clays. Several channels, asymmetric in cross-profile, were shaped by periglacial slope denudation.

    Description: Internationally, the description and interpretation of glacial sediments and landforms largely follow a set of uniform guidelines and terminology. Sediments are normally described according to their lithofacies characteristics (e.g. diamicton, sorted sands), and only after closer inspection and investigation are genetic terms applied (e.g. till, glaciofluvial outwash). Mixing of sedimentological and geomorphological terminology does not occur. In German-speaking countries, however, the term moraine is used for glaciogenic sediments and landforms such as end moraines and also adopted for till plains (“ground moraine landscapes”, “old/young morainic landscapes” etc.). Similar traditions of the latter kind are sometimes found as a relict in Scandinavian texts, and an equally profound mixing of terms is found in much of the French literature. The authors argue here that this mixture not only leads to unnecessary confusion for students but also makes international communication more difficult, especially when the terminological inconsistencies are as extensive and non-systematic as in the German community at present. The present paper presents a systematic overview of the state-of-the-art of till terminology, thereby providing the necessary background information for a useful description and interpretation of field evidence for communicating results in German and hopefully aiding more efficient communication of German Quaternary geologists and geomorphologists internationally. The aim is to provide a sedimentological terminology that is in agreement with international standards and can readily be distinguished from geomorphological vocabulary. The authors recommend that usage of the term ground moraine, for example, is restricted to certain landform associations encountered in NW Central Europe, and excluded from use when discussing sediments. For primary glaciogenic sediments sensu stricto the term till should be used only where appropriate sedimentological evidence exists. A process-based subdivision of till types (e.g. deformation, lodgement till) is not useful in most cases, because as a community we do not have the tools to reliably distinguish such processes at a macro-scale. This recognition has led to the creation of the highly useful umbrella term subglacial traction till and its distinction from overridden primary sediments that are termed glaciotectonite. The present contribution translates the older terminology to the internationally-accepted terminology that follows the scientifically-robust approach of splitting descriptive terminology – based on a lithofacies approach (e.g. diamicton) – from the latter interpretative stage (e.g. subglacial traction till, debris flow deposit). The authors present translations of the different till schemes that have existed through time and link these to the current state of the art, citing several examples and clear diagnostic criteria to distinguish various types of diamictic sediments. This contribution stresses that the majority of diamictons encountered in glacial environments, especially in ice-marginal settings, are not usually and certainly not automatically subglacial traction tills.

    Description: Die Produktion von Biokraftstoffen ist wegen der Konkurrenz mit der Lebensmittelproduktion ein weltweit umstrittenes Thema. Die vorliegende Arbeit beschäftigt sich mit einer Pflanze, die giftig ist, und daher bei der Biokraftstoff-Produktion nicht in Konkurrenz mit der Lebensmittelproduktion tritt. Der Name der Pflanze ist Jatropha curcas und sie ist unter anderem in Südamerika heimisch. Die Autorin hat eine Methode zur Abschätzung des Anbaupotenzials von J. curcas entwickelt, die auf einer ArcGIS-Datenbank, internationalen Anbau-Erfahrungen und einer Studie der bolivianischen Regierung und dem Entwicklungsprogramm der Vereinten Nationen beruht. Die vorliegende Untersuchung ist eine Fall-Studie zur möglichen Biokraftstoff-Produktion aus J. curcas in einer Region in Bolivien. Im Untersuchungsgebiet El Gran Chaco im Departamento Santa Cruz sind rund 7 Mio. ha Boden fortgeschritten erodiert, dies entspricht 86 % der Gesamtoberfläche des Untersuchungsgebiets. Zugleich ist das Untersuchungsgebiet durch niedrigen Niederschlag, Dürre-Anfälligkeit, trockene Luft, und Nährstoffarmut charakterisiert. Neben der Bestimmung des J. curcas Anbaupotenzials im Untersuchungsgebiet werden auch die Auswirkungen des Anbaus präsentiert. Es werden Handlungsempfehlungen zu einer nachhaltigen Biodieselproduktion im industriellen Maßstab für Regierung, Bauern und Investoren vorgenommen. Dabei werden ökologische und sozioökonomische Kriterien berücksichtigt. Die Arbeit kommt zu dem Ergebnis, dass für Länder wie Bolivien mit entsprechenden klimatischen Bedingungen, genügend Ackerfläche, geringer Bevölkerungsdichte und ausreichender Flächen-Verfügbarkeit sowie Anfälligkeit für Krisen wie Nahrungsmittel- und Energieknappheit, der Anbau von Biokraftstoffpflanzen ein Beitrag für wirtschaftliches Wachstum sein und auch regionale Probleme wie den steigenden Diesel-Importbedarf (teilweise) lösen kann.

    Description: Stockholm, Hamburg, Vitoria-Gasteiz, Nantes, Kopenhagen, Bristol, Ljubljana, Essen - das sind die Europäischen Umwelthauptstädte der Jahre 2010 bis 2017. Sie wurden in einem jährlichen europaweiten Wettbewerb von der Europäischen Kommission als Vorbildstädte ausgewählt. Sie zeigen aus Sicht der Europäischen Kommission, wie eine zukunftsfähige, umweltorientierte Stadtentwicklung im 21. Jahrhundert aussehen kann. Welchen EU-Benchmark markieren diese acht Städte für die Gestaltung eines klimaschonenden Personenverkehrs in der Stadt?
