    Beschreibung / Inhaltsverzeichnis: The cryosphere, that region of the world where water is temporarily or permanently frozen, plays a crucial role on our planet. Recent developments in remote sensing techniques, and the acquisition of new data sets, have resulted in significant advances in our understanding of all components of the cryosphere and its processes. This book, based on contributions from 40 leading experts, offers a comprehensive and authoritative overview of the methods, techniques and recent advances in applications of remote sensing of the cryosphere.

    Beschreibung / Inhaltsverzeichnis: This textbook aims to be a one stop shop for those interested in aerosols and their impact on the climate system. It starts with some fundamentals on atmospheric aerosols, atmospheric radiation and cloud physics, then goes into techniques used for in-situ and remote sensing measurements of aerosols, data assimilation, and discusses aerosol-radiation interactions, aersol-cloud interactions and the multiple impacts of aerosols on the climate system. The book aims to engage those interested in aerosols and their impacts on the climate system: graduate and PhD students, but also post-doctorate fellows who are new to the field or would like to broaden their knowledge. The book includes exercises at the end of most chapters. Atmospheric aerosols are small (microscopic) particles in suspension in the atmosphere, which play multiple roles in the climate system. They interact with the energy budget through scattering and absorption of solar and terrestrial radiation. They also serve as cloud condensation and ice nuclei with impacts on the formation, evolution and properties of clouds. Finally aerosols also interact with some biogeochemical cycles. Anthropogenic emissions of aerosols are responsible for a cooling effect that has masked part of the warming due to the increased greenhouse effect since pre-industrial time. Natural aerosols also respond to climate changes as shown by observations of past climates and modelling of the future climate.

    Beschreibung / Inhaltsverzeichnis: Recent climate model simulations indicated that sulfate (SO4) formed from ship emissions may be one of the major contributors to the negative anthropogenic aerosol radiative forcing. Due to increasingly stringent regulations on the maximum sulfur content of ship fuels this contribution is expected to decrease strongly in the future. Possibly, nitrate (NO3) formation will compensate for part of the reduction, but measurements indicate that it may be crucial to include coarse mode particle interactions with condensable trace gases in order to quantify this effect. However, none of the aerosol (sub)models previously used for such assessments accounted for the coarse mode particle effects. This provided the motivation to extend one of those submodels, namely MADE, in the present work. The new submodel, MADE3, is based on the second generation of MADE, called MADE-in. It includes nine lognormal modes to represent three size ranges with three types of aerosol particles each. The associated increase in complexity w.r.t. to MADE and MADE-in required a complete revision of the code and careful reexamination of the underlying physical assumptions, as only the fine modes had been considered in the gas–particle interactions in the predecessor submodels. The main new features of MADE3 are the ability of coarse mode particles to take up condensing vapors and to coagulate with fine mode particles, and the gas–particle partitioning of chlorine, which is mainly contained in sea spray (SS) particles. In order to test the algorithms used in the new submodel it was run in a box model setup and the results were compared to those obtained in an analogous setup with the much more detailed, particle-resolved aerosol model PartMC-MOSAIC. The comparison was performed for an idealized marine boundary layer test case and showed improved performance of MADE3 over MADE in the representation of coarse mode particles and total aerosol composition. Subsequently, MADE3 was implemented into the atmospheric chemistry general circulation model EMAC. Due to the new mode structure this required extensive adaptations to other submodels, specifically to the one used for cloud and precipitation processing of aerosol particles. EMAC does not track interstitial aerosol particles separately from those immersed in cloud droplets, ice crystals, or precipitation. Hence, a sophisticated scheme was devised and implemented for the assignment of the in-cloud or in-precipitation aerosol to one of four possible modes, instead of just one possible mode in the MADE case. The coupled model, EMAC with MADE3, was thoroughly evaluated by comparison of simulation output to station network measurements of near-surface aerosol component mass concentrations, to airborne measurements of vertical aerosol mass mixing ratio and number concentration profiles, to ground-based and airborne measurements of particle size distributions, and to station network and satellite measurements of aerosol optical depth. Satisfactory agreement with the observations was obtained and it was thus shown that MADE3 is ready for application within EMAC. The results from an identically designed simulation with the predecessor submodel MADE led to the conclusion that a fraction of the secondary aerosol species partitions to the coarse modes in MADE3 and is thus removed more quickly from the atmosphere. Furthermore, a new evaluation method was developed, which allows for comparison of model output to size-resolved electron microscopy measurements of particle composition. Both submodels, MADE3 and MADE, were finally used in EMAC simulations of the effect of ship emissions on the atmospheric aerosol. As in previous studies for year 2000 conditions, SO4 was found to be the dominant species in the fine modes in this context. In contrast to SO4, the major fraction of ship emissions-induced near-surface NO3 was found to partition to the coarse modes in the MADE3 simulations. A similar amount of fine mode NO3 as in the present and former MADE simulations was also formed. Hence, fine mode particle growth due to ship emissions was also similar, and was reduced in idealized simulations of a future low-sulfur fuel scenario. Particle volume concentration decreased by about 1 % due to ship emissions in the MADE3 simulations, but not in the MADE simulations. This finding was independent of the fuel sulfur content. In summary, the inclusion of coarse mode particle interactions and the gas–particle partitioning of chlorine could alter prior conclusions on the climate effect of ship emissions-induced aerosol perturbations, mainly due to the differences in NO3 formation. This climate effect will be re-quantified in a follow-up study by coupling the MADE3 aerosol to a two-moment cloud microphysics scheme. Further planned applications of the new submodel include the quantification of climate effects of aerosol perturbations via their influence on ice clouds as well as simulations with boundary conditions specific to measurement campaigns. Results from the latter may lead to further model improvements and can also provide guidance for the interpretation of measurement results.

    Beschreibung / Inhaltsverzeichnis: In ice-rich permafrost regions, changes in the permafrost thermal regime cause surface disturbances. These changes are amplified by the increase in air temperatures recorded in the Arctic in the past decades. Thermokarst is a process that leads to surface subsidence and formation of characteristic landforms following thawing of ice-rich permafrost or melting of massive ice. Thermokarst is widespread on hillslopes and the number of associated landforms is increasing in the Arctic. Through this process large amounts of material are eroded and transported to the sea or accumulate along hillslopes. While hillslope thermokarst modifies terrestrial and aquatic ecosystems, there is limited understanding of its environmental impact at a regional scale. In this thesis we quantify the environmental impacts of hillslope thermokarst on the valley and nearshore ecosystems along the Yukon Coast, Canada. Using supervised machine learning, we identified geomorphic factors that favour the development of coastal retrogressive thaw slump (RTS), one of the most dynamic hillslope thermokarst landform. Coastal geomorphology and ground ice type and content play a major role in RTS occurrence. Using aerial photographs and satellite imagery, we traced the evolution of RTSs between 1952 and 2011. During this time, the number and areal coverage of RTSs increased by 73%. RTSs eroded and partly released to the nearshore zone organic carbon contained in millions of cubic meters of material. Our results show that 56% of the RTSs identified along the coast in 2011 have eroded 16.6 × 10^6 m3 of material; a large part (45%) was transported alongshore due to coastal processes. Moreover, we show that RTSs are a major contributor to the carbon budget in the nearshore ecosystem: 17% of the coastal RTSs identified in 2011 contributed annually up to 0.6% of the organic carbon released by coastal retreat along the Yukon Coast. To assess the impact of hillslope thermokarst on the terrestrial ecosystem, we measured the spatial distribution of soil organic carbon (SOC) and total nitrogen (TN) along hillslopes in three Arctic valleys. We highlight the high spatial variability in the distribution of SOC and TN in the valleys. This distribution is caused by complex soil processes occurring along the hillslopes. Hillslope thermokarst impacts the degradation of organic matter and affects the storage of SOC and TN.

    Beschreibung / Inhaltsverzeichnis: Widespread landscape changes are presently observed in the Arctic and are most likely to accelerate in the future, in particular in permafrost regions which are sensitive to climate warming. To assess current and future developments, it is crucial to understand past environmental dynamics in these landscapes. Causes and interactions of environmental variability can hardly be resolved by instrumental records covering modern time scales. However, long-term environmental variability is recorded in paleoenvironmental archives. Lake sediments are important archives that allow reconstruction of local limnogeological processes as well as past environmental changes driven directly or indirectly by climate dynamics. This study aims at reconstructing Late Quaternary permafrost and thermokarst dynamics in central-eastern Beringia, the terrestrial land mass connecting Eurasia and North America during glacial sea-level low stands. In order to investigate development, processes and influence of thermokarst dynamics, several sediment cores from extant lakes and drained lake basins were analyzed to answer the following research questions: 1. When did permafrost degradation and thermokarst lake development take place and what were enhancing and inhibiting environmental factors? 2. What are the dominant processes during thermokarst lake development and how are they reflected in proxy records? 3. How did, and still do, thermokarst dynamics contribute to the inventory and properties of organic matter in sediments and the carbon cycle? Methods applied in this study are based upon a multi-proxy approach combining sedimentological, geochemical, geochronological, and micropaleontological analyses, as well as analyses of stable isotopes and hydrochemistry of pore-water and ice. Modern field observations of water quality and basin morphometrics complete the environmental investigations. The investigated sediment cores reveal permafrost degradation and thermokarst dynamics on different time scales. The analysis of a sediment core from GG basin on the northern Seward Peninsula (Alaska) shows prevalent terrestrial accumulation of yedoma throughout the Early to Mid Wisconsin with intermediate wet conditions at around 44.5 to 41.5 ka BP. This first wetland development was terminated by the accumulation of a 1-meter-thick airfall tephra most likely originating from the South Killeak Maar eruption at 42 ka BP. A depositional hiatus between 22.5 and 0.23 ka BP may indicate thermokarst lake formation in the surrounding of the site which forms a yedoma upland till today. The thermokarst lake forming GG basin initiated 230 ± 30 cal a BP and drained in Spring 2005 AD. Four years after drainage the lake talik was still unfrozen below 268 cm depth. A permafrost core from Mama Rhonda basin on the northern Seward Peninsula preserved a full lacustrine record including several lake phases. The first lake generation developed at 11.8 cal ka BP during the Lateglacial-Early Holocene transition; its old basin (Grandma Rhonda) is still partially preserved at the southern margin of the study basin. Around 9.0 cal ka BP a shallow and more dynamic thermokarst lake developed with actively eroding shorelines and potentially intermediate shallow water or wetland phases (Mama Rhonda). Mama Rhonda lake drainage at 1.1 cal ka BP was followed by gradual accumulation of terrestrial peat and top-down refreezing of the lake talik. A significant lower organic carbon content was measured in Grandma Rhonda deposits (mean TOC of 2.5 wt%) than in Mama Rhonda deposits (mean TOC of 7.9 wt%) highlighting the impact of thermokarst dynamics on biogeochemical cycling in different lake generations by thawing and mobilization of organic carbon into the lake system. Proximal and distal sediment cores from Peatball Lake on the Arctic Coastal Plain of Alaska revealed young thermokarst dynamics since about 1,400 years along a depositional gradient based on reconstructions from shoreline expansion rates and absolute dating results. After its initiation as a remnant pond of a previous drained lake basin, a rapidly deepening lake with increasing oxygenation of the water column is evident from laminated sediments, and higher Fe/Ti and Fe/S ratios in the sediment. The sediment record archived characterizing shifts in depositional regimes and sediment sources from upland deposits and re-deposited sediments from drained thaw lake basins depending on the gradually changing shoreline configuration. These changes are evident from alternating organic inputs into the lake system which highlights the potential for thermokarst lakes to recycle old carbon from degrading permafrost deposits of its catchment. The lake sediment record from Herschel Island in the Yukon (Canada) covers the full Holocene period. After its initiation as a thermokarst lake at 11.7 cal ka BP and intense thermokarst activity until 10.0 cal ka BP, the steady sedimentation was interrupted by a depositional hiatus at 1.6 cal ka BP which likely resulted from lake drainage or allochthonous slumping due to collapsing shore lines. The specific setting of the lake on a push moraine composed of marine deposits is reflected in the sedimentary record. Freshening of the maturing lake is indicated by decreasing electrical conductivity in pore-water. Alternation of marine to freshwater ostracods and foraminifera confirms decreasing salinity as well but also reflects episodical re-deposition of allochthonous marine sediments. Based on permafrost and lacustrine sediment records, this thesis shows examples of the Late Quaternary evolution of typical Arctic permafrost landscapes in central-eastern Beringia and the complex interaction of local disturbance processes, regional environmental dynamics and global climate patterns. This study confirms that thermokarst lakes are important agents of organic matter recycling in complex and continuously changing landscapes.

    Beschreibung / Inhaltsverzeichnis: Книга посвящена дискуссионной проблеме, касающейся палеогеографического развития Российской Арктики. Проведено исследование эволюции криолитозоны в позднем кайнозое и предложена реконструкция палеогеографических обстановок нескольких эпох плейстоцена-голоцена, когда сформировались многие черты, определившие современный природный облик Севера России. В основу реконструкции положен анализ крупных залежных подземных льдов, широко распространенных в Арктике (на суше и на шельфе) в отложениях всех эпох плейстоцена и голоцена и обладающих высокой палеогеографической информативностью. Среди подземных льдов выявлен новый генетический тип - лед субмаринного происхождения. Получен ряд новых выводов. Показано, что развитие западного и восточного секторов Российской Арктики в плейстоцене проходило не одинаково: западный сектор большую часть плейстоцена развивался в условиях трансгрессивного режима и морского осадконакопления, восточный сектор - в течение всего периода в условиях континентального· режима и преимущественно озерно-аллювиального и лагунного осадконакопления. Оледенение в регионе в целом было невелико, а распространение покровных ледников ограничивалось с востока полуостровом Канин. Сделан вывод, отрицающий ведущую роль гляциоэвстатических процессов в колебаниях уровня Арктического бассейна и выводящий на первый план роль неотектонических процессов, связанных с рифтовой структурой Северного Ледовитого океана. Книга рассчитана на широкий круг специалистов, чья профессиональная деятельность связана с Арктикой и ее природой, а также же на всех тех, кто интересуется науками о Земле.
    Beschreibung / Inhaltsverzeichnis: Translation of the abstract: The book is devoted to a debatable problem concerning the paleogeographical development of the Russian Arctic. A study of the evolution of the cryolithozone in the late Cenozoic was carried out and a reconstruction was proposed paleogeographic settings of several epochs of the Pleistocene-Holocene, when many features were formed that determined the modern natural appearance of the North of Russia. The reconstruction is based on the analysis of large fallow underground ice, which is widespread in the Arctic (on land and on the shelf) in deposits of all Pleistocene and Holocene epochs and has a high paleogeographic information content. Among underground ice, a new genetic type has been identified - ice of submarine origin. A number of new conclusions have been obtained. It is shown that the development of the western and eastern sectors of the Russian Arctic in the Pleistocene was not the same: the western sector developed for most of the Pleistocene under the conditions of a transgressive regime and marine sedimentation, the eastern sector - throughout the entire period under the conditions of a continental regime and predominantly lacustrine-alluvial and lagoonal sedimentation . Glaciation in the region as a whole was not great, and the distribution of sheet glaciers was limited from the east by the Kanin Peninsula. A conclusion is drawn that denies the leading role of glacioeustatic processes in the level fluctuations of the Arctic Basin and brings to the fore the role of neotectonic processes associated with the rift structure of the Arctic Ocean. The book is intended for a wide range of professionals whose professional activities are related to the Arctic and its nature, as well as for all those who are interested in the Earth sciences.

    Beschreibung / Inhaltsverzeichnis: Georg Forster (1754-1794) war eine der faszinierendsten Gestalten seiner Zeit: glänzender Schriftsteller, Naturforscher, Entdecker, Zeichner, Übersetzer und entschiedener Revolutionär. Auf seiner Weltumsegelung mit James Cook berührte er Eisberge mit den eigenen Händen, lief den Strand von Tahiti entlang, besuchte fremde Völker, lebte unter »Menschenfressern« und überquerte Ozeane und den Äquator. Und er stand im Zentrum des politischen Geschehens, als er - inspiriert von der Französischen Revolution - 1793 die »Mainzer Republik« ausrief, die erste Republik auf deutschem Boden. Anschaulich und fesselnd portraitiert Jürgen Goldstein dieses Ausnahmeleben, in dem sich »Freiheit« und »Naturgewalt« berührten. Niemand ist auf vergleichbare Weise das erfahrungsgetriebene Experiment eingegangen, die Natur mit dem Politischen kurzzuschließen. Die Funken, die Forster aus seinen Leitvorstellungen schlug, erhellten für einen Weltaugenblick die Aussicht, es könne so etwas wie natürliche Revolutionen geben. Jürgen Goldstein, geboren 1962, lehrt als Professor für Philosophie an der Universität Koblenz-Landau. Maßgeblich von Hans Blumenberg inspiriert, widmen sich seine Studien der Genese und dem Profil der Moderne. Seine Bücher befassen sich mit der Herausbildung der neuzeitlichen Subjektivität und Rationalität, der politischen Philosophie des 20. Jahrhunderts und der Geschichte der Naturwahrnehmung.
    Beschreibung / Inhaltsverzeichnis: Wagemutiger Entdeckungsreisender, empfindsamer Naturbetrachter, glühender Revolutionär: Georg Forster befuhr mit James Cook die Weltmeere, verfasste glänzende Reiseerzählungen und stürzte sich mit provokanten Ansichten in die politischen Debatten seiner Zeit. Er war in Mainz Mitbegründer der ersten Republik auf deutschem Boden und starb - gescheitert und vereinsamt - im Pariser Exil. In seiner ebenso fesselnden wie kenntnisreichen Biographie entwirft Jürgen Goldstein mit Eleganz und Tiefenschärfe ein anschauliches Panorama von Forsters rastlosem Leben zwischen Euphorie und Elend - das Leben eines Weltbürgers, der davon überzeugt war, dass sich die Freiheit eines Tages mit Naturgewalt ihren Wag bahnen müsse.

    Beschreibung / Inhaltsverzeichnis: The Atlas content is presented by 8 large sections and 39 subsections which present characteristics of the key glaciological regions; there are also two auxiliary subsections: introductory one and the reference part that is indicator of geographical regions. The whole material is placed on the 590 pages of the Atlas. Themes and subjects of the maps are given in a system of three levels which one with corresponding number of base scales and, respectively, the territorial coverage. In addition to a possibility to look through all digital maps, any user can also see original vector layers in the format of shp. files which are saved in decimal degrees .This makes possible to project the data into any view, to design own project, to transform the data into other GIS-formats, to analyze the information together with own or other data with geographical conjunction .

    Beschreibung / Inhaltsverzeichnis: The Yukon Coast in Canada is an ice-rich permafrost coast and highly sensitive to changing environmental conditions. Retrogressive thaw slumps are a common thermoerosion feature along this coast, and develop through the thawing of exposed ice-rich permafrost on slopes and removal of accumulating debris. They contribute large amounts of sediment, including organic carbon and nitrogen, to the nearshore zone. The objective of this study was to 1) identify the climatic and geomorphological drivers of sediment-meltwater release, 2) quantify the amount of released meltwater, sediment, organic carbon and nitrogen, and 3) project the evolution of sediment-meltwater release of retrogressive thaw slumps in a changing future climate. The analysis is based on data collected over 18 days in July 2013 and 18 days in August 2012. A cut-throat flume was set up in the main sediment-meltwater channel of the largest retrogressive thaw slump on Herschel Island. In addition, two weather stations, one on top of the undisturbed tundra and one on the…

    Beschreibung / Inhaltsverzeichnis: Taxonomy plays a central role in biological sciences. It provides a communication system for scientists as it aims to enable correct identification of the studied organisms. As a consequence, species descriptions should seek to include as much available information as possible at species level to follow an integrative concept of ‘taxonomics’. Here, we describe the cryptic species Epimeria frankei sp. nov. from the North Sea, and also redescribe its sister species, Epimeria cornigera. The morphological information obtained is substantiated by DNA barcodes and complete nuclear 18S rRNA gene sequences. In addition, we provide, for the first time, full mitochondrial genome data as part of a metazoan species description for a holotype, as well as the neotype. This study represents the first successful implementation of the recently proposed concept of taxonomics, using data from high-throughput technologies for integrative taxonomic studies, allowing the highest level of confidence for both biodiversity and ecological research.

    Beschreibung / Inhaltsverzeichnis: Climate change is one of the greatest threats facing humanity; a definitive manifestation of the well-worn links between progress and devastation. This book explores the complex relationship that the corporate world has with climate change, and examines the central role of corporations in shaping political and social responses to the climate crisis. The book's principal message is that despite the need for dramatic economic and political change, corporate capitalism continues to rely upon the maintenance of 'business as usual'. The authors explore the different processes through which corporations engage with climate change. Key discussion points include climate change as business risk; corporate climate politics; the role of justification and compromise; and managerial identity and emotional reactions to climate change. Written for researchers and graduate students, this book moves beyond descriptive and normative approaches to provide a sociologically and critically informed theory of corporate responses to climate change.

    Beschreibung / Inhaltsverzeichnis: The Arctic is a region that has seen exponential growth as a space of geopolitical interest over the past decade. This insightful book is the first to analyse the European Union’s Arctic policy endeavours of the early 21st Century from a critical geopolitical perspective. Exploring the EU’s decade-long undertaking to construct legitimacy in the Arctic between 2008 and 2017, Andreas Raspotnik investigates whether the EU can figure prominently in the Arctic region as an international actor. This book presents the EU’s interest in the Arctic as a fascinating test case for how the EU aims to assert its policies and values in a neighbouring region. This contemporary and intriguing book will be an invaluable resource for scholars and students of international relations, European studies, geography, and Arctic studies, as well as those on courses relating to international organisations and global/regional politics. It will also appeal to the broader public with an interest in the challenges and opportunities of the Arctic region.

    Beschreibung / Inhaltsverzeichnis: This collection of papers by internationally known scientists in the field of geocryology was originally presented as a series of lectures at the University of British Columbia in 1980-81 in honour of J. Ross MacKay. Together they illustrate the central dilemma in a science where fieldwork must be undertaken in the harsh periglacial environment and where, consequently, it is difficult to test theory rigorously. The papers provide a valuable overview of the current status of international research in a wide area of the field - permafrost, patterned ground, and cold climate phenomena and processes. The treatment varies from anecdotal, historical, and descriptive to mathematical. The studies on soil freezing, ice formation and thaw are relatively sophisticated treatments that are physically sound, theoretically based, and quantitatively precise, as are the computational methods and the extension of results to engineering site evaluations given in other contributions. The regional accounts of geocryological and nival phenomena, on the other hand, remain entirely empirical and, for the most part, qualitative. This critical mismatch of understanding between microscale and regional scale is emphasized in the review of the status of periglacial studies. Ross MacKay's most valuable contribution to science has been his consistent demonstration of how to occupy the middle ground by applying simple physical concepts to explain variations in the landscape.

    Beschreibung / Inhaltsverzeichnis: "This report provides a summary of the present state of knowledge concerning contaminants in northern Canada. This knowledge base was the subject of a scientific evaluation meeting held in Ottawa, February 28-March 2, 1989. Approximately 50 scientists representing a broad spectrum of interests attended the meeting including a representative of each of the other seven circumpolar countries. An integrated ecosystem approach was taken to assess the contaminants issue which considered all aspects of the problem from sources to transport, freshwater, terrestrial and marine systems, human exposure through diets, and finally implications to human health"--Foreword

    Beschreibung / Inhaltsverzeichnis: The greatest wilderness on earth, the circumpolar Arctic has for centuries stirred our imagination and challenged us to explore its vast lands and seas. The Arctic World captures the spirit of this most northerly frontier - the majesty of its landscapes, the beauty of its plants and animals, the remarkable history of its peoples. Encompassing the northern reaches of seven countries and an area of 28 million square miles, the Arctic is, in fact, one natural realm where plants, animals and humans have learned to live in a hostile climate. Its expanses of land and water, however, are not always the barren tracts of popular myth. There are towering mountain ranges, the largest forest in the world, spectacular displays of flowers in the spring, and -a rich variety of sea and land birds and mammals. Its people range from the Inuit of the Canadian Arctic, Greenland and Alaska to the Lapps of Scandinavia and the Chukchi of Siberia. The Arctic World offers an exciting visual journey through this immense land. The 130 color and 100 black and white photographs, taken in each of the polar countries by renowned photographers, range from breathtaking scenery to intimate portraits of people at work and at play. Those depicting traditional ways of life that have all but disappeared from the modern Arctic are important visual records of the unique heritage of northern peoples. Old engravings and early photographs of arctic explorers, whalers and native men and women provide a historical perspective. The fascinating story of the adaptation of man, plants and animals to the arctic environment is told by six polar experts from around the world. They focus on the history of the Arctic from the ice ages to the present, the impact of European exploration, the astonishing variety of arctic flora and fauna, and the future of the Arctic in the face of twentieth-century technology.

    Beschreibung / Inhaltsverzeichnis: Earth's climate varies continuously across space and time, but humankind has witnessed only a small snapshot of its entire history, and instrumentally documented it for a mere 200 years. Our knowledge of past climate changes is therefore almost exclusively based on indirect proxy data, i.e. on indicators which are sensitive to changes in climatic variables and stored in environmental archives. Extracting the data from these archives allows retrieval of the information from earlier times. Obtaining accurate proxy information is a key means to test model predictions of the past climate, and only after such validation can the models be used to reliably forecast future changes in our warming world. The polar ice sheets of Greenland and Antarctica are one major climate archive, which record information about local air temperatures by means of the isotopic composition of the water molecules embedded in the ice. However, this temperature proxy is, as any indirect climate data, not a perfect recorder of past climatic variations. Apart from local air temperatures, a multitude of other processes affect the mean and variability of the isotopic data, which hinders their direct interpretation in terms of climate variations. This applies especially to regions with little annual accumulation of snow, such as the Antarctic Plateau. While these areas in principle allow for the extraction of isotope records reaching far back in time, a strong corruption of the temperature signal originally encoded in the isotopic data of the snow is expected. This dissertation uses observational isotope data from Antarctica, focussing especially on the East Antarctic low-accumulation area around the Kohnen Station ice-core drilling site, together with statistical and physical methods, to improve our understanding of the spatial and temporal isotope variability across different scales, and thus to enhance the applicability of the proxy for estimating past temperature variability. The presented results lead to a quantitative explanation of the local-scale (1–500 m) spatial variability in the form of a statistical noise model, and reveal the main source of the temporal variability to be the mixture of a climatic seasonal cycle in temperature and the effect of diffusional smoothing acting on temporally uncorrelated noise. These findings put significant limits on the representativity of single isotope records in terms of local air temperature, and impact the interpretation of apparent cyclicalities in the records. Furthermore, to extend the analyses to larger scales, the timescale-dependency of observed Holocene isotope variability is studied. This offers a deeper understanding of the nature of the variations, and is crucial for unravelling the embedded true temperature variability over a wide range of timescales.

    Beschreibung / Inhaltsverzeichnis: This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature.

    Beschreibung / Inhaltsverzeichnis: Assumed comparable environmental conditions of early Mars and early Earth in 3.7 Ga ago – at a time when first fossil records of life on Earth could be found – suggest the possibility of life emerging on both planets in parallel. As conditions changed, the hypothetical life on Mars either became extinct or was able to adapt and might still exist in biological niches. The controversial discussed detection of methane on Mars led to the assumption, that it must have a recent origin – either abiotic through active volcanism or chemical processes, or through biogenic production. Spatial and seasonal variations in the detected methane concentrations and correlations between the presence of water vapor and geological features such as subsurface hydrogen, which are occurring together with locally increased detected concentrations of methane, gave fuel to the hypothesis of a possible biological source of the methane on Mars. Therefore the phylogenetically old methanogenic archaea, which have evolved under early Earth conditions, are often used as model-organisms in astrobiological studies to investigate the potential of life to exist in possible extraterrestrial habitats on our neighboring planet. In this thesis methanogenic archaea originating from two extreme environments on Earth were investigated to test their ability to be active under simulated Mars analog conditions. These extreme environments – the Siberian permafrost-affected soil and the chemoautotrophically based terrestrial ecosystem of Movile cave, Romania – are regarded as analogs for possible Martian (subsurface) habitats. Two novel species of methanogenic archaea isolated from these environments were described within the frame of this thesis. It could be shown that concentrations up to 1 wt% of Mars regolith analogs added to the growth media had a positive influence on the methane production rates of the tested methanogenic archaea, whereas higher concentrations resulted in decreasing rates. Nevertheless it was possible for the organisms to metabolize when incubated on water-saturated soil matrixes made of Mars regolith analogs without any additional nutrients. Long-term desiccation resistance of more than 400 days was proven with reincubation and indirect counting of viable cells through a combined treatment with propidium monoazide (to inactivate DNA of destroyed cells) and quantitative PCR. Phyllosilicate rich regolith analogs seem to be the best soil mixtures for the tested methanogenic archaea to be active under Mars analog conditions. Furthermore, in a simulation chamber experiment the activity of the permafrost methanogen strain Methanosarcina soligelidi SMA-21 under Mars subsurface analog conditions could be proven. Through real-time wavelength modulation spectroscopy measurements the increase in the methane concentration at temperatures down to -5 °C could be detected. The results presented in this thesis contribute to the understanding of the activity potential of methanogenic archaea under Mars analog conditions and therefore provide insights to the possible habitability of present-day Mars (near) subsurface environments. Thus, it contributes also to the data interpretation of future life detection missions on that planet. For example the ExoMars mission of the European Space Agency (ESA) and Roscosmos which is planned to be launched in 2018 and is aiming to drill in the Martian subsurface

    Beschreibung / Inhaltsverzeichnis: The Arctic sea-ice cover plays an important role for the global climate system. Sea ice and the overlying snow cover reflect up to eight times more of the solar radiation than the underlying ocean. Hence, they are important for the global energy budget, and changes in the sea-ice cover can have a large impact on the Arctic climate and beyond. In the past 36 years the ice cover reduced significantly. The largest decline is observed in September, with a rate of more than 12% per decade. The negative trend is accompanied by large inter-annual sea-ice variability: in September the sea-ice extent varies by up to 27% between years. The processes controlling the large variability are not well understood. In this thesis the atmospheric contribution to the inter-annual sea-ice variability is explored. The focus is specifically on the thermodynamical effects: processes that are associated with a temperature change of the ice cover and sea-ice melt. Atmospheric reanalysis data are used to identify key processes, while experiments with a state-of-the-art climate model are conducted to understand their relevance throughout different seasons. It is found that in years with a very low September sea-ice extent more heat and moisture is transported in spring into the area that shows the largest ice variability. The increased transport is often associated with similar atmospheric circulation patterns. Increased heat and moisture over the Arctic result in positive anomalies of water vapor and clouds. These alter the amount of downward radiation at the surface: positive cloud anomalies allow for more longwave radiation and less shortwave radiation. In spring, when the solar inclination is small, positive cloud anomalies result in an increased surface warming and an earlier seasonal melt onset. This reduces the ice cover early in the season and allows for an increased absorption of solar radiation by the surface during summer, which further accelerates the ice melt. The modeling experiments indicate that cloud anomalies of similar magnitude during other seasons than spring would likely not result in below-average September sea ice. Based on these results a simple statistical sea-ice prediction model is designed, that only takes into account the downward longwave radiation anomalies or variables associated with it. Predictive skills are similar to those of more complex models, emphasizing the importance of the spring atmosphere for the annual sea-ice evolution.

    Beschreibung / Inhaltsverzeichnis: This book covers the basics of processing and spectral analysis of monovariate discrete-time signals. The approach is practical, the aim being to acquaint the reader with the indications for and drawbacks of the various methods and to highlight possible misuses. The book is rich in original ideas, visualized in new and illuminating ways, and is structured so that parts can be skipped without loss of continuity. Many examples are included, based on synthetic data and real measurements from the fields of physics, biology, medicine, macroeconomics etc., and a complete set of MATLAB exercises requiring no previous experience of programming is provided. Prior advanced mathematical skills are not needed in order to understand the contents: a good command of basic mathematical analysis is sufficient. Where more advanced mathematical tools are necessary, they are included in an Appendix and presented in an easy-to-follow way. With this book, digital signal processing leaves the domain of engineering to address the needs of scientists and scholars in traditionally less quantitative disciplines, now facing increasing amounts of data.

    Beschreibung / Inhaltsverzeichnis: The book offers a modern, comprehensive, and holistic view of natural gas seepage, defined as the visible or invisible flow of gaseous hydrocarbons from subsurface sources to Earth’s surface. Beginning with definitions, classifications for onshore and offshore seepage, and fundamentals on gas migration mechanisms, the book reports the latest findings for the global distribution of gas seepage and describes detection methods. Seepage implications are discussed in relation to petroleum exploration, environmental impacts (hazards, pollution, atmospheric emissions, and past climate change), emerging scientific issues (abiotic gas and methane on Mars), and the role of seeps in ancient cultures. With an updated bibliography and an integrated analysis of available data, the book offers a new fundamental awareness - gas seepage is more widespread than previously thought and influences all of Earth’s external “spheres”, including the hydrosphere, atmosphere, biosphere, and anthroposphere.

    Beschreibung / Inhaltsverzeichnis: Alfred Wegener aimed to create a revolution in science which would rank with those of Nicolaus Copernicus and Charles Darwin. After completing his doctoral studies in astronomy at the University of Berlin, Wegener found himself drawn not to observatory science but to rugged fieldwork, which allowed him to cross into a variety of disciplines. The author of the theory of continental drift - the direct ancestor of the modern theory of plate tectonics and one of the key scientific concepts of the past century - Wegener also made major contributions to geology, geophysics, astronomy, geodesy, atmospheric physics, meteorology, and glaciology. Remarkably, he completed this pathbreaking work while grappling variously with financial difficulty, war, economic depression, scientific isolation, illness, and injury. He ultimately died of overexertion on a journey to probe the Greenland ice cap and calculate its rate of drift. This landmark biography - the only complete account of the scientist's fascinating life and work - is the culmination of more than twenty years of intensive research. In Alfred Wegener, Mott T. Greene places Wegener's background and theoretical advances in earth science in the context of his brilliantly eclectic career, bringing Wegener to life by analyzing his published scientific work, delving into all of his surviving letters and journals, and tracing both his passionate commitment to science and his thrilling experiences as a polar explorer, a military officer during World War I, and a world record-setting balloonist. In the course of writing this book, Greene traveled to every place that Alfred Wegener lived and worked - to Berlin, rural Brandenburg, Marbug, Hamburg, and Heidelberg in Germany; to Innsbruck and Graz in Austria; and onto the Greenland ice cap. He also pored over archives in Copenhagen, Munich, Marburg, Graz, and Bremerhaven, where the majority of Wegener's surviving papers are found. Written with great immediacy and descriptive power, Alfred Wegener is a powerful portrait of the scientist who pioneered the modern notion of unified earth science. The book should be of interest not only to earth scientists, students of polar travel and exploration, and historians but to all readers who are fascinated by the great minds of science.
