    Description / Table of Contents: Siebenundzwanzig Antarktisfahrer hat Herausgeber Gert Lange um ihre Erlebnisberichte gebeten. Die Forscher - es sind Vertreter der verschiedensten Fachrichtungen, wie Geodäsie, Strahlungsmessung, Ionosphärenuntersuchung, Glaziologie, Geologie, Meteorologie, Zoologie - erläutern in allgemein-verständlicher Form ihre wissenschaftlichen Aufgaben und Ergebnisse, schildern ebenso gefahrenvolle wie absonderliche Begebenheiten und beeindruckende Naturerscheinungen. So erlebte zum Beispiel Dr. Klaus Dreßler, Teilnehmer der 17. SAE, eine besonders schöne Fata Morgana: "... Auf der Gegenstation in 1,2km Entfernung erschien hoch über unserem Kettenfahrzeug eine große Flagge oder Rauchfahne, die sich nach unten ausdehnte, bis das Fahrzeug plötzlich dreifach überhöht erschien. Ebenso alle anderen Gegenstände. Durchs Fernrohr sah ich Artur ein zweites Mal über sich selbst, aber auf dem Kopfe stehend und mitunter so lang gestreckt wie in einem Zerrspiegel ... Gegenstände, sonst nicht sichtbar, kamen über dem Horizont zum Vorschein. Besonders schön: die roten und schwarzen Tafeln der Landebahnmarkierung. Sie waren sonst hinter einem Schneerücken verborgen, jetzt tauchten sie in ihrer normalen Grüße etwas zehn Meter über der Oberfläche auf. Dann verwandelten sie ich in schlanke Säulen. Der eigenartigste Effekt war, daß die Traktoren, Bulldozer und anderen Geräte für die Flugplatzunterhaltung, sonst in derselben Entfernung deutlich sichtbar, zeitweise ganz verschwanden. Alle diese Erscheinungen wechselten langsam innerhalb von ein bis fünf Minuten..." Derartige, auf Grund besonders starker Ablenkung des Lichtes in der Antarktis vorkommende Erscheinungen beeinträchtigen natürlich die Meßarbeiten, ebenso wie tiefe Temperaturen und häufige Schneestürme sehr hinderlich für topographische und andere Arbeiten sind. Seit 1959 überwinterten mehr als siebzig DDR-Wissenschaftler im Rahmen der SAE (Sowjetische Antarktisexpeditionen) auf dem weißen Kontinent, der mit seinen Schönheiten und Widrigkeiten von Mensch und Maschie immer wieder Bewährung in schwierigen Situationen verlangt.

    Description / Table of Contents: In seiner Doktorarbeit behandelte er ein Thema aus der Astronomie. Sein Lehrbuch "Thermodynamik der Atmosphäre", das in mehreren Auflagen erschien, wies ihn als Meteorologen aus. In Graz erhielt er eine Professur nicht nur für die Wetterkunde, sondern auch für Geophysik. Bei vier großen Grönlandexpeditionen verwirklichte er seinen Jugendtraum, Polarforschung zu treiben. Und fast nur am Rande gehört hierher, daß er in jungen Jahren einen Weltrekord im Ballondauerflug aufgestellt hatte ... Von einer der großen, vielseitigen Forscherpersönlichkeiten unseres Jahrhunderts ist hier die Rede: von Alfred Wegener, der seinen dauerhaften Ruhm 1912 mit der revolutionären Hypothese begründete, wonach die Festländer gar nicht so "fest" seien, wie man bis dahin angenommen hatte, sondern daß sie im Laufe der Erdgeschichte langsam wanderten. Zu seinen Lebzeiten für die meisten ein "Märchenerzähler", wurde Wegener in jüngster Zeit, Jahrzehnte nach seinem tragischen Tod in Grönland, für viele ein "neuer Kopernikus": an Wegener schieden sich die Geister. Selten hat ein neues Gedankengebäude über die Entstehung der Erdkruste, ihrer Gebirge und Ozeane so anregend für Geologen und Geophysiker gewirkt wie die "Drifthypothese". Die von Professor M. Schwarzbach verfaßte Biographie zeichnet nicht nur ein Lebensbild Wegeners, sondern umfaßt damit gleichzeitig ein Stück Wissenschaftsgeschichte, ein herausragendes Kapitel der Erforschung der Erde - von der Verschiebung der Kontinente und der heute im Vordergrund stehenden "Plattentektonik" bis hin zur Eiszeitforschung, den Strahlungskurven von Milankovitch und der "nächsten Eiszeit".

    Description / Table of Contents: This book is designed as a comprehensive mathematical introduction to the science of the behaviour of glaciers and ice sheets in their geophysical environment. Its main objective is to provide a better fundamental understanding of the problems of ice mechanics and fluid mechanics of large ice masses, and to connect and unify some of the approaches that have been developed in different disciplines concerned with glaciers and ice sheets. The first two chapters provide the physical background by treating ice within the framework of continuum physics and material science. The central part of the book deals with the conceptualization and mathematical formulation of glacier and ice sheet flow. Considerations concerning fluid mechanics and thermodynamics are given equal attention. The aim is to deduce common glaciological formulae from first principles and to state clearly the assumptions which lie behind the approximations. This allows the extension of the results - known to glaciologists in plane flow only - to three dimensions, thus paving the way for further research.

    Description / Table of Contents: This report investigates the feasibility of clearing ice from the shipping channel of the St. Marys River. Four basic concepts are investigated: disposal under the ice, disposal on top of the ice, slurrying, and rafting. Each technique was found to have application in limited portions of the river with the exception of disposal on top of the adjacent ice sheet which is deemed feasible throughout the river system. Disposal onto the adjacent ice sheet will increase the free stream velocity less than 1.0 ft/s (30.5 cm/s) and raise the water level less than 1.0 ft (0.30 m). Further model and field tests are recommended to validate the findings of this report.

    Description / Table of Contents: This study was conducted to determine the short- and long-term physical, chemical and biological effects of spills of hot Prudhoe Bay crude oil on permafrost terrain near Fairbanks, Alaska. Two experimental oil spills, one in winter and one in summer, of 7570 liters (2000 gallons) were made at a forest site. The winter-spill oil moved within the surface moss layer beneath the snow. The summer-spill oil moved primarily below the moss in the organic soil. The oil moved faster and further downslope in the summer spill. Oil in the winter spill stopped during the first day but remobilized and flowed further downslope in the spring. The total area affected by the summer spill was nearly one and one-half times as large as that affected by the winter spill. The initial heat of the spilled oil had little measurable thermal effect on the soil. However, thaw depth significantly increased following two full thaw seasons. The greatest increases occurred beneath oil blackened surfaces. Evaporation of volatile components is the most significant weathering process in the first two years. Volatiles evaporated faster from surface oil than from oil carried deeper into the soil profile. Microbial degradation has not been observed. The indigenous soil microbial populations responded differently to winter and summer oil applications, ranging from inhibition to stimulation, with stimulation appearing to predominate. Vegetation showed both immediate and long-term damage. Damage was greatest near the top of the slope and in areas with surface oil. Deciduous species showed damage faster than evergreen species.

    Description / Table of Contents: Weekly measurements of the thickness of lake, river and fast sea ice made over a period of 10 to 15 years at 66 locations in Canada and Alaska are analyzed, and the portion of the data relating to maximum ice thickness and decay (i.e. the decrease in ice thickness) is examined. Ice thickness curves revealed individual patterns of ice decay, and comparisons between locations disclosed major contrasts in the amount of ice accretion and the times of maximum ice and ice clearance. Although many factors affect the ice decay process, this study investigates in detail the effect of thawing temperatures. Concurrent measurements of the air temperature at each location made it possible to analyze the relationship between accumulated thawing degree-days (ATDD) and ice cover decay. Other factors affecting ice ablation and breakup, such as snow-ice formation, snow cover depth, solar radiation and wind are also discussed.

    Description / Table of Contents: The primary objectives of this study were to 1) prepare a map from Landsat imagery of the Upper Susitna River Basin drainage network, lakes, glaciers and snowfields, 2) identify possible faults and lineaments within the upper basin and within a 100-km radius of the proposed Devil Canyon and Watana dam sites as observed on Landsat imagery, and 3) prepare a Landsat-derived map showing the distribution of surficial geologic materials and poorly drained areas. The EROS Digital Image Enhancement System (EDIES) provided computer- enhanced images of Landsat-1 scene 5470-19560. The EDIES false color composite of this scene was used as the base for mapping drainage network, lakes, glaciers and snowfields, six surficial geologic materials units and poorly drained areas. We used some single-band and other color composites of Landsat images during interpretation. All the above maps were prepared by photointerpretation of Landsat images without using computer analysis, aerial photographs, field data, or published reports. These other data sources were used only after the mapping was completed to compare and verify the information interpreted and delineations mapped from the Landsat images. Four Landsat-1 MSS band 7 winter scenes were used in the photomosaic prepared for the lineament mapping. We mapped only those lineaments related to reported regional tectonics, although there were many more lineaments evident on the Landsat photomosaic.

    Description / Table of Contents: The conditions that lead to initial breakup of a solid ice on a river due to rapid water level variations are analyzed. The analysis is based on the theory of beams on an elastic foundation. First cracking is assumed to occur when the bending moment induced in the ice cover by the wave exceeds the flexural strength of the ice cover.

    Description / Table of Contents: Existing classifications for deposits in the glacial environment are inadequate and inconsistent. Deposits should be classified both descriptively and genetically; adequate descriptive classifications already exist. A major problem for previous genetic classifications has been that glacial deposition and the resulting deposits' properties were poorly understood. On the basis of three criteria-sediment source, uniqueness to the glacial environment, and preservation of glacier-derived properties-deposits in the glacial environment result from either of two groups of processes: primary or secondary. Primary processes release the debris of the glacier directly and form deposits that may bear properties related to the glacier and its mechanics. Their deposits are classified genetically as till and are the only deposits indicative of glaciation. In contrast, secondary processes mobilize, rework, transport and resediment debris and deposits in the glacial environment. They develop new, nonglacial properties in their deposits, while destroying or substantially modifying glacier-derived properties. Interpretation of their properties may provide information on the depositional are classified genetically according to the depositional process just as they are in other sedimentary environments. This genetic classification differs from previous classifications in that not all diamictons deposited in the glacial environment are classified as till; it is based strictly on process-related criteria. The origin of properties of glacial deposits in relation to the glacier's mechanics and environment must be recognized if the mechanisms and depositional processes of former glaciers are to be precisely understood.

    Description / Table of Contents: Several proposed methods for treating the momentum flux between drifting sea ice and the underlying ocean are interpreted in terms of simple planetary-boundary-layer (PBL) turbulence theory. The classical two-layer approach, in which the solution for a thin surface layer is matched to an Ekman solution for the outer layer, is used to derive several forms of the drag law. These forms range from linear (where stress is proportional to relative speed), through quadratic (where stress is proportional to relative speed squared), to a Rossby-similarity law like that used to express frictional drag on geostrophic wind in the atmosphere. Only formulations which conform with Rossby-similarity scaling are consistent with free-drift data from the 1975 AIDJEX drift station experiment.

    Description / Table of Contents: The reflection of solar radiation by a snow cover in situ and the apparent influence of selected substrates were examined in wavelength bands centered at 0.81, 1.04, 1.10, 1.30, 1.50 and 1.80 micrometers. Substrates included winter wheat, timothy, corn, alfalfa, grass, concrete and subsurface layers of 'crusty' snow and ice. Reasonable qualitative agreement between measurements and theoretical predictions was demonstrated, with indications of quantitative agreement in the definition of a 'semi-infinite depth' of snow cover. It was concluded that ultimate quantitative agreement between theory and measurement will require that an 'optically effective grain size' be defined in terms of physically measuarable dimensions or meteorologically predictable characteristics of the ice crystals composing the snowpack.

    Description / Table of Contents: Development of the hydropower potential of Bradley Lake, Alaska, would greatly increase winter freshwater discharge from the Bradley River into Kachemak Bay, which may result in increased ice formation and related ice-induced problems. The objectives of this investigation were to describe winter surface circulation in the bay and document ice distribution patterns for predicting where additional ice might be transported if it forms. Landsat MSS bands 5 and 7 and RBV imagery with 70% cloud cover or less, taken between 1 November and 30 April each year from 1972 to 1980, were analyzed. Surface circulation patterns inferred from suspended sediment patterns and ice distribution and movement were observed and mapped from the Landsat imagery. The generalized circulation patterns indicate that any additional ice formed due to future increased winter discharge from Bradley River would be likely to accumulate along Homer Spit and to be blown into the outer bay by the dominant northerly winter winds.

    Description / Table of Contents: This thesis investigates how the permafrost microbiota responds to global warming. In detail, the constraints behind methane production in thawing permafrost were linked to methanogenic activity, abundance and composition. Furthermore, this thesis offers new insights into microbial adaptions to the changing environmental conditions during global warming. This was assesed by investigating the potential ecological relevant functions encoded by plasmid DNA within the permafrost microbiota. Permafrost of both interglacial and glacial origin spanning the Holocene to the late Pleistocene, including Eemian, were studied during long-term thaw incubations. Furthermore, several permafrost cores of different stratigraphy, soil type and vegetation cover were used to target the main constraints behind methane production during short-term thaw simulations. Short- and long-term incubations simulating thaw with and without the addition of substrate were combined with activity measurements, amplicon and metagenomic sequencing of permanently frozen and seasonally thawed active layer. Combined, it allowed to address the following questions. i) What constraints methane production when permafrost thaws and how is this linked to methanogenic activity, abundance and composition? ii) How does the methanogenic community composition change during long-term thawing conditions? iii) Which potential ecological relevant functions are encoded by plasmid DNA in active layer soils? The major outcomes of this thesis are as follows. i) Methane production from permafrost after long-term thaw simulation was found to be constrained mainly by the abundance of methanogens and the archaeal community composition. Deposits formed during periods of warmer temperatures and increased precipitation, (here represented by deposits from the Late Pleistocene of both interstadial and interglacial periods) were found to respond strongest to thawing conditions and to contain an archaeal community dominated by methanogenic archaea (40% and 100% of all detected archaea). Methanogenic population size and carbon density were identified as main predictors for potential methane production in thawing permafrost in short-term incubations when substrate was sufficiently available. ii) Besides determining the methanogenic activity after long-term thaw, the paleoenvironmental conditions were also found to influence the response of the methanogenic community composition. Substantial shifts within methanogenic community structure and a drop in diversity were observed in deposits formed during warmer periods, but not in deposits from stadials, when colder and drier conditions occurred. Overall, a shift towards a dominance of hydrogenotrophic methanogens was observed in all samples, except for the oldest interglacial deposits from the Eemian, which displayed a potential dominance of acetoclastic methanogens. The Eemian, which is discussed to serve as an analogue to current climate conditions, contained highly active methanogenic communities. However, all potential limitation of methane production after permafrost thaw, it means methanogenic community structure, methanogenic population size, and substrate pool might be overcome after permafrost had thawed on the long-term. iii) Enrichments with soil from the seasonally thawed active layer revealed that its plasmid DNA (‘metaplasmidome’) carries stress-response genes. In particular it encoded antibiotic resistance genes, heavy metal resistance genes, cold shock proteins and genes encoding UV-protection. Those are functions that are directly involved in the adaptation of microbial communities to stresses in polar environments. It was further found that metaplasmidomes from the Siberian active layer originate mainly from Gammaproteobacteria. By applying enrichment cultures followed by plasmid DNA extraction it was possible to obtain a higher average contigs length and significantly higher recovery of plasmid sequences than from extracting plasmid sequences from metagenomes. The approach of analyzing ‘metaplasmidomes’ established in this thesis is therefore suitable for studying the ecological role of plasmids in polar environments in general. This thesis emphasizes that including microbial community dynamics have the potential to improve permafrost-carbon projections. Microbially mediated methane release from permafrost environments may significantly impact future climate change. This thesis identified drivers of methanogenic composition, abundance and activity in thawing permafrost landscapes. Finally, this thesis underlines the importance to study how the current warming Arctic affects microbial communities in order to gain more insight into microbial response and adaptation strategies.

    Description / Table of Contents: Eine Medien- und Wissensgeschichte von Biologie und Ozeanographie im Kielwasser der Walfänger. Immer wieder entzieht sich der Wal wissenschaftlicher Klassifikation und Darstellbarkeit. Wale sind buchstäblich nicht zu fassen - als sich die neuen biologischen Wissenschaften im 19. Jahrhundert daran machten, »das Leben« zu erklären, blieb das der Wale ein Problem. Doch Walfänger durchkreuzten auf ihren Spuren im 19. Jahrhundert die Meere der Welt. Kartographen erschlossen auf den Spuren dieser Walfänger die Nordwestpassage und den pazifischen Ozean, während Naturhistoriker und Zoologen sie in die Lebensräume der Wale begleiten. Felix Lüttge erzählt die Geschichte der Walfänger, die den Walen, und der Wissenschaftler, die wiederum den Walfängern folgten.Es ist eine Medien- und Wissensgeschichte des Wals wie auch der Meere, die auf seinen Spuren durchfahren und vermessen wurden. Felix Lüttge beschreibt die komplexen Austauschprozesse, mit denen Walfänger und Wissenschaftler ökonomisches, ozeanographisches, zoologisches und geographisches Wissen hervorbrachten.

    Description / Table of Contents: The arctic-boreal treeline is a transition zone from taiga to tundra covering a vast area in Siberia. It often features large environmental gradients and reacts sensitively to changes in the environment. For example, the expansion of shrubs and a northward movement of the treeline are observable in Siberia as a response to the warming climate. The changes in vegetation across the treeline are known to influence the water chemistry in the lakes. This causes further alteration to the composition and diversity of sensitive aquatic organisms such as diatoms and macrophytes. Despite the rising awareness of the complex climate-feedback mechanisms of terrestrial plants, the understanding of their assembly rules and about responses of aquatic biomes in the surrounding treeline lakes is still limited. The goal of this thesis is to examine the previous and present biodiversity of terrestrial and freshwater biomes from the Siberian treeline ecotone, as well as their reactions to environmental changes. In particular, this thesis attempts to ...

    Description / Table of Contents: Die Digitalisierung verändert rasant unsere Demokratie und ihre Mechanismen. In der Arena der politischen Meinungs- und Willensbildung ist es komplex und unübersichtlich geworden. Neue Akteursgruppen betreten die Bühne, klassische Medien haben ihre Kontrollfunktion über Debatten in weiten Teilen eingebüßt, Populismus und Fake News bedrohen unsere politische Kultur und Organisationen müssen sich strategisch, strukturell und kommunikativ auf den Umbruch in eine digitale Gesellschaft vorbereiten. Trotzdem ist sich der »Political Native« Juri Schnöller sicher: Die Chance für den Aufbruch in eine bessere Gesellschaft ist so groß wie nie zuvor. Egal ob Politik, Zivilgesellschaft, öffentliche Verwaltung, NGOs oder Wirtschaft - alle ringen um Aufmerksamkeit für ihre Anliegen in dieser digitalen Public Arena und haben die gleichen Fragen: Wie baue ich erfolgreich eine digitale Kommunikationsstrategie? Was brauche ich, um Menschen wirklich für mein Anliegen zu begeistern? Wo erreiche ich meine Zielgruppen und mit welchen Inhalten auf welchen Kanälen kann ich sie ansprechen und involvieren? Wie schaffe ich es nachhaltig, meine Ziele zu verwirklichen und mit meinen Werten einen Beitrag für eine bessere Gesellschaft zu leisten? Das Public Arena Playbook gibt als erstes seiner Art allen Kommunikatoren eine konkrete Navigation an die Hand, um in der öffentlichen Arena im digitalen Zeitalter wertebasiert, wirksam und willensstark zu kommunizieren. Kompakt werden die besten Strategien, Tools und Methoden vorgestellt und von praktischen Beispielen und spannenden Interviews begleitet. Es liefert neben Handlungsanweisungen aber auch ein klares ethisches Wertefundament für eine konstruktive Debatte im digitalen Raum - positiv, integrativ, inklusiv. Denn: Nie war mehr Anfang als jetzt!

    Description / Table of Contents: Nur wenn sich unser Umgang mit Land grundlegend ändert, können die Klimaschutzziele erreicht, der dramatische Verlust der biologischen Vielfalt abgewendet und das globale Ernährungssystem nachhaltig gestaltet werden. Der WBGU schlägt in diesem Gutachten fünf exemplarische Mehrgewinnstrategien vor, um Konkurrenzen zwischen Nutzungsansprüchen zu überwinden. Diese sollten durch fünf Governance-Strategien vorangetrieben werden, darunter insbesondere die Setzung geeigneter Rahmenbedingungen, eine Neuorientierung der EU-Politik und die Errichtung von Gemeinschaften gleichgesinnter Staaten. „Der jüngste Bericht des WBGU mit dem Titel ‚Landwende im Anthropozän: Von der Konkurrenz zur Integration‘ macht deutlich, dass wir einen grundlegenden Wandel im Umgang mit Land benötigen, um den Klimawandel zu begrenzen, den Verlust der biologischen Vielfalt umzukehren und nachhaltige Ernährungssysteme zu schaffen. Gesundes Land ist endlich, aber Veränderungen im Verhalten von Konsumenten und Unternehmen, kombiniert mit besserer Landnutzungsplanung und Landmanagement, können dazu beitragen, die Nachfrage nach lebenswichtigen Gütern und Dienstleistungen zu befriedigen, ohne die Landressourcen zu gefährden. Dieser Bericht zeigt, wie durch besseres Landmanagement Klimaschutz gefördert, Ökosysteme geschützt und Ernährungssysteme nachhaltig werden können.“

    Description / Table of Contents: The deciduous needle tree larch (Larix Mill.) covers more than 80% of the Asian boreal forests. Only a few Larix species constitute the vast forests and these species differ markedly in their ecological traits, most importantly in their ability to grow on and stabilize underlying permafrost. The pronounced dominance of the summergreen larches makes the Asian boreal forests unique, as the rest of the northern hemisphere boreal forests is almost exclusively dominated by evergreen needle-leaf forests. Global warming is impacting the whole world but is especially pronounced in the arctic and boreal regions. Although adapted to extreme climatic conditions, larch forests are sensitive to varying climatic conditions. By their sheer size, changes in Asian larch forests as range shifts or changes in species composition and the resulting vegetation-climate feedbacks are of global relevance. It is however still uncertain if larch forests will persist under the ongoing warming climate or if they will be replaced by evergreen forests. It is therefore of great importance to understand how these ecosystems will react to future climate warmings and if they will maintain their dominance. One step in the better understanding of larch dynamics is to study how the vast dominant forests developed and why they only established in northern Asia. A second step is to study how the species reacted to past changes in the climate. The first objective of this thesis was to review and identify factors promoting Asian larch dominance. I achieved this by synthesizing and comparing reported larch occurrences and influencing components on the northern hemisphere continents in the present and in the past. The second objective was to find a possibility to directly study past Larix populations in Siberia and specifically their genetic variation, enabling the study of geographic movements. For this, I established chloroplast enrichment by hybridization capture from sedimentary ancient DNA (sedaDNA) isolated from lake sediment records. The third objective was to use the established method to track past larch populations, their glacial refugia during the Last Glacial Maximum (LGM) around 21,000 years before present (ka BP), and their post-glacial migration patterns. To study larch promoting factors, I compared the present state of larch species ranges, areas of dominance, their bioclimatic niches, and the distribution on different extents and thaw depths of permafrost. The species comparison showed that the bioclimatic niches greatly overlap between the American and Asian species and that it is only in the extremely continental climates in which only the Asian larch species can persist. I revealed that the area of dominance is strongly connected to permafrost extent but less linked to permafrost seasonal thaw depths. Comparisons of the paleorecord of larch between the continents suggest differences in the recolonization history. Outside of northern Asia and Alaska, glacial refugial populations of larch were confined to the southern regions and thus recolonization could only occur as migration from south to north. Alaskan larch populations could not establish wide-range dominant forest which could be related to their own genetically depletion as separated refugial population. In Asia, it is still unclear whether or not the northern refugial populations contributed and enhanced the postglacial colonization or whether they were replaced by populations invading from the south in the course of climate warming. Asian larch dominance is thus promoted partly by adaptions to extremely continental climates and by adaptations to grow on continuous permafrost but could be also connected to differences in glacial survival and recolonization history of Larix species. Except for extremely rare macrofossil findings of fossilized cones, traditional methods to study past vegetation are not able to distinguish between larch species or populations. Within the scope of this thesis, I therefore established a method to retrieve genetic information of past larch populations to distinguish between species. Using the Larix chloroplast genome as target, I successfully applied the method of DNA target enrichment by hybridization capture on sedaDNA samples from lake records and showed that it is able to distinguish between larch species. I then used the method on samples from lake records from across Siberia dating back up to 50 ka BP. The results allowed me to address the question of glacial survival and post-glacial recolonization mode in Siberian larch species. The analyzed pattern showed that LGM refugia were almost exclusively constituted by L. gmelinii, even in sites of current L. sibirica distribution. For included study sites, L. sibirica migrated into its extant northern distribution area only in the Holocene. Consequently, the post-glacial recolonization of L. sibirica was not enhanced by northern glacial refugia. In case of sites in extant distribution area of L. gmelinii, the absence of a genetic turn-over point to a continuous population rather than an invasion of southern refugia. The results suggest that climate has a strong influence on the distribution of Larix species and that species may also respond differently to future climate warming. Because species differ in their ecological characteristics, species distribution is also relevant with respect to further feedbacks between vegetation and climate. With this thesis, I give an overview of present and past larch occurrences and evaluate which factors promote their dominance. Furthermore, I provide the tools to study past Larix species and give first important insights into the glacial history of Larix populations.

    Description / Table of Contents: This book provides a cross-disciplinary overview of permafrost and the carbon cycle by providing an introduction into the geographical distribution of permafrost, with a focus on the distribution of permafrost and its soil carbon reservoirs. The chapters explain the basic physical properties and processes of permafrost soils: ice, mineral and organic components, and how these interact with climate, vegetation and geomorphological processes. In particular, the book covers the role of the large quantities of ice in many permafrost soils which are crucial to understanding carbon cycle processes. An explanation is given on how permafrost becomes loaded with ice and carbon. Gas hydrates are also introduced. Structures and processes formed by the intense freeze-thaw action in the active layer are considered (e.g. ice wedging, cryoturbation), and the processes that occur as the permafrost thaws, (pond and lake formation, erosion). The book introduces soil carbon accumulation and decomposition mechanisms and how these are modified in a permafrost environment. A separate chapter deals with deep permafrost carbon, gas reservoirs and recently discovered methane emission phenomena from regions such as Northwest Siberia and the Siberian yedoma permafrost.

    Description / Table of Contents: This is a textbook for non-atmospheric specialists who work in the coastal zone. Its purpose will be to help coastal environmental, engineering, and planning professionals to understand coastal atmospheric processes. This in turn will allow more effective communication with climate modelers, atmospheric environmental consultants, and members of the media. The coastal environment is among the most intensively used and chronically abused components of the Earth-ocean-atmosphere system. It is also home to an ever-increasing proportion of humanity with their increasing development, trade, transportation, and industrial activities, amid increasing impacts of natural hazards. The atmosphere is an integral part of the system, with all of the above human activities affecting and being affected by atmospheric processes and hazards. Yet few of the specialists studying the coastal environment have expertise on atmospheric processes, this therefore presents a highly relevant textbook on coastal atmospheric processes.

    Description / Table of Contents: High-resolution images of phytoplankton cells such as diatoms or desmids, which are useful for monitoring water quality, can now be provided by digital microscopes, facilitating the automated analysis and identification of specimens. Conventional approaches are based on optical microscopy; however, manual image analysis is impractical due to the huge diversity of this group of microalgae and its great morphological plasticity. As such, there is a need for automated recognition techniques for diagnostic tools (e.g. environmental monitoring networks, early warning systems) to improve the management of water resources and decision-making processes. Describing the entire workflow of a bioindicator system, from capture, analysis and identification to the determination of quality indices, this book provides insights into the current state-of-the-art in automatic identification systems in microscopy. .

    Description / Table of Contents: This two-volume book provides a comprehensive, detailed understanding of paleoclimatology beginning by describing the “proxy data” from which quantitative climate parameters are reconstructed and finally by developing a comprehensive Earth system model able to simulate past climates of the Earth. It compiles contributions from specialists in each field who each have an in-depth knowledge of their particular area of expertise. The first volume is devoted to “Finding, dating and interpreting the evidence”. It describes the different geo-chronological technical methods used in paleoclimatology. Different fields of geosciences such as: stratigraphy, magnetism, dendrochronology, sedimentology, are drawn from and proxy reconstructions from ice sheets, terrestrial (speleothems, lakes, and vegetation) and oceanic data, are used to reconstruct the ancient climates of the Earth. The second volume, entitled “Investigation into ancient climates,” focuses on building comprehensive models of past climate evolution. The chapters are based on understanding the processes driving the evolution of each component of the Earth system (atmosphere, ocean, ice). This volume provides both an analytical understanding of each component using a hierarchy of models (from conceptual to very sophisticated 3D general circulation models) and a synthetic approach incorporating all of these components to explore the evolution of the Earth as a global system. As a whole this book provides the reader with a complete view of data reconstruction and modeling of the climate of the Earth from deep time to present day with even an excursion to include impacts on future climate.

    Description / Table of Contents: The Arctic nearshore zone plays a key role in the carbon cycle. Organic-rich sediments get eroded off permafrost affected coastlines and can be directly transferred to the nearshore zone. Permafrost in the Arctic stores a high amount of organic matter and is vulnerable to thermo-erosion, which is expected to increase due to climate change. This will likely result in higher sediment loads in nearshore waters and has the potential to alter local ecosystems by limiting light transmission into the water column, thus limiting primary production to the top-most part of it, and increasing nutrient export from coastal erosion. Greater organic matter input could result in the release of greenhouse gases to the atmosphere. Climate change also acts upon the fluvial system, leading to greater discharge to the nearshore zone. It leads to decreasing sea-ice cover as well, which will both increase wave energy and lengthen the open-water season. Yet, knowledge on these processes and the resulting impact on the nearshore zone is scarce, because access to and instrument deployment in the nearshore zone is challenging. Remote sensing can alleviate these issues in providing rapid data delivery in otherwise non-accessible areas. However, the waters in the Arctic nearshore zone are optically complex, with multiple influencing factors, such as organic rich suspended sediments, colored dissolved organic matter (cDOM), and phytoplankton. The goal of this dissertation was to use remotely sensed imagery to monitor processes related to turbidity caused by suspended sediments in the Arctic nearshore zone. In-situ measurements of water-leaving reflectance and surface water turbidity were used to calibrate a semi-empirical algorithm which relates turbidity from satellite imagery. Based on this algorithm and ancillary ocean and climate variables, the mechanisms underpinning nearshore turbidity in the Arctic were identified at a resolution not achieved before. The calibration of the Arctic Nearshore Turbidity Algorithm (ANTA) was based on in-situ measurements from the coastal and inner-shelf waters around Herschel Island Qikiqtaruk (HIQ) in the western Canadian Arctic from the summer seasons 2018 and 2019. It performed better than existing algorithms, developed for global applications, in relating turbidity from remotely sensed imagery. These existing algorithms were lacking validation data from permafrost affected waters, and were thus not able to reflect the complexity of Arctic nearshore waters. The ANTA has a higher sensitivity towards the lowest turbidity values, which is an asset for identifying sediment pathways in the nearshore zone. Its transferability to areas beyond HIQ was successfully demonstrated using turbidity measurements matching satellite image recordings from Adventfjorden, Svalbard. The ANTA is a powerful tool that provides robust turbidity estimations in a variety of Arctic nearshore environments. Drivers of nearshore turbidity in the Arctic were analyzed by combining ANTA results from the summer season 2019 from HIQ with ocean and climate variables obtained from the weather station at HIQ, the ERA5 reanalysis database, and the Mackenzie River discharge. ERA5 reanalysis data were obtained as domain averages over the Canadian Beaufort Shelf. Nearshore turbidity was linearly correlated to wind speed, significant wave height and wave period. Interestingly, nearshore turbidity was only correlated to wind speed at the shelf, but not to the in-situ measurements from the weather station at HIQ. This shows that nearshore turbidity, albeit being of limited spatial extent, gets influenced by the weather conditions multiple kilometers away, rather than in its direct vicinity. The large influence of wave energy on nearshore turbidity indicates that freshly eroded material off the coast is a major contributor to the nearshore sediment load. This contrasts results from the temperate and tropical oceans, where tides and currents are the major drivers of nearshore turbidity. The Mackenzie River discharge was not identified as a driver of nearshore turbidity in 2019, however, the analysis of 30 years of Landsat archive imagery from 1986 to 2016 suggests a direct link between the prevailing wind direction, which heavily influences the Mackenzie River plume extent, and nearshore turbidity around HIQ. This discrepancy could be caused by the abnormal discharge behavior of the Mackenzie River in 2019. This dissertation has substantially advanced the understanding of suspended sediment processes in the Arctic nearshore zone and provided new monitoring tools for future studies. The presented results will help to understand the role of the Arctic nearshore zone in the carbon cycle under a changing climate.

    Description / Table of Contents: This book provides an introduction to the critical role of ecosystem-based disaster risk resilience (Eco-DRR) for building community resilience to multiple environmental risks such as rising heat, water stress, and pollution. Blue-green infrastructure (BGI) is an Eco-DRR tool that is an under-explored paradigm and can respond as one common strategy to targets set by the Sustainable Development Goals (UNDP), Climate Agreements (UNEP), the Sendai Framework (UNISDR), and the New Urban Agenda (UNCHS). Highlighted here in a systematic way is the importance of blue-green infrastructures in resilience building. The purpose is to introduce readers to the challenging context of development and opportunity creation for Eco-DRR. The roles of policy, scientific research, and implementation are presented cohesively. An attractive proposition of the book is a collection of case studies from different parts of the world where integration of BGI is experimented with at various levels of success. It envisages that shared tacit experiences from the realm of practice will further strengthen explicit knowledge. The focus in this book is on need and context building, policy and science (investigation, analysis, and design), case studies, and a road map for the future in four successive parts. Each part is self-sufficient yet linked to its predecessor, successor, or both, as the case may be.

    Description / Table of Contents: This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.

    Description / Table of Contents: Human-driven greenhouse emissions are increasing the velocity of climate change and the frequency and intensity of climate extremes far above historical levels. These changes, along with other human-perturbations, are setting the conditions for more rapid and abrupt ecosystem dynamics and collapse. This book presents new evidence on the rapid emergence of ecosystem collapse in response to the progression of anthropogenic climate change dynamics that are expected to intensify as the climate continues to warm. Discussing implications for biodiversity conservation, the chapters provide examples of such dynamics globally covering polar and boreal ecosystems, temperate and semi-arid ecosystems, as well as tropical and temperate coastal ecosystems. Given its scope, the volume appeals to scientists in the fields of general ecology, terrestrial and coastal ecology, climate change impacts, and biodiversity conservation.

    Description / Table of Contents: This book is dedicated to the analysis of bottom waters flows through underwater channels of the Atlantic Ocean. The study is based on recent observations of the authors, analysis of historical data, numerical modeling, and literature review. For example, studying both the measurements from the World Ocean Circulation experiment in the 1990s and recent measurements reveals the decadal variations of water properties in the ocean. Seawater is cooled at high latitudes, descends to the ocean bottom, and slowly flows to the tropical latitudes and further. This current is slow in the deep basins, but intensifies in the abyssal channels connecting the basins. The current overflows submarine topographic structures and sometimes forms deep cataracts when water descends over slopes by several hundred meters. The flow of Antarctic Bottom Water (AABW) is studied on the basis of CTD sections combined with Lowered Acoustic Doppler Profiling (LADCP) carried out annually, and long-term moored measurements of currents. This book is a collection of oceanographic data, interpretation, and analysis, which can be used by field oceanographers, specialists in numerical modeling, and students who specialize in oceanography.

    Description / Table of Contents: This book presents the result of an innovative challenge, to create a systematic literature overview driven by machine-generated content. Questions and related keywords were prepared for the machine to query, discover, collate and structure by Artificial Intelligence (AI) clustering. The AI-based approach seemed especially suitable to provide an innovative perspective as the topics are indeed both complex, interdisciplinary and multidisciplinary, for example, climate, planetary and evolution sciences. Springer Nature has published much on these topics in its journals over the years, so the challenge was for the machine to identify the most relevant content and present it in a structured way that the reader would find useful. The automatically generated literature summaries in this book are intended as a springboard to further discoverability. They are particularly useful to readers with limited time, looking to learn more about the subject quickly and especially if they are new to the topics. Springer Nature seeks to support anyone who needs a fast and effective start in their content discovery journey, from the undergraduate student exploring interdisciplinary content, to Master- or PhD-thesis developing research questions, to the practitioner seeking support materials, this book can serve as an inspiration, to name a few examples. It is important to us as a publisher to make the advances in technology easily accessible to our authors and find new ways of AI-based author services that allow human-machine interaction to generate readable, usable, collated, research content.

    Description / Table of Contents: This atlas is an attempt to translate and consolidate the available knowledge on permafrost. It is a timely book suffused with the compelling enthusiasm of its authors and contributors. Close to a hundred individuals participated in its making, and it does a magnificent job at describing permafrost with maps, words, art, and stories. Far from being an academic product in the traditional sense, it gathers the knowledge from the voices of scientists, Indigenous Peoples, northern residents, and local practitioners to provide a holistic and inclusive view of today’s challenges in the “country of permafrost”.

    Description / Table of Contents: Extreme weather and climate events are one of the greatest dangers for present-day society. Therefore, it is important to provide reliable statements on what changes in extreme events can be expected along with future global climate change. However, the projected overall response to future climate change is generally a result of a complex interplay between individual physical mechanisms originated within the different climate subsystems. Hence, a profound understanding of these individual contributions is required in order to provide meaningful assessments of future changes in extreme events. One aspect of climate change is the recently observed phenomenon of Arctic Amplification and the related dramatic Arctic sea ice decline, which is expected to continue over the next decades. The question to what extent Arctic sea ice loss is able to affect atmospheric dynamics and extreme events over mid-latitudes has received a lot of attention over recent years and still remains a highly debated topic. In this respect, the objective of ...
