Description / Table of Contents: 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.

Description / Table of Contents: 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.

Description / Table of Contents: 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.

Description / Table of Contents: 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.

Description / Table of Contents: Alfred Wegener (1880-1930) war einer der bedeutendsten deutschen Naturwissenschaftler des vergangenen Jahrhunderts. Er untersuchte die Erdatmosphäre mit Drachen und Fesselballonen, erforschte das Wesen der gefürchteten Windhosen, fuhr vier Mal auf wissenschaftliche Expeditionen nach Grönland und stellte einen Weltrekord im bemannten Ballonflug auf. In diesem Buch wird das Leben dieses vielseitigen Forschers erzählt. Daneben wird sein wissenschaftliches Hauptwerk, die Kontinentaldrifttheorie, und seine Theorie zur Entstehung der Mondkrater durch Meteoritenbombardement beleuchtet, an die er Ideen über die Entstehung der Erde selbst knüpfte.

Description / Table of Contents: 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.

Description / Table of Contents: 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.

Description / Table of Contents: 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.

Description / Table of Contents: 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.

Description / Table of Contents: PAST Gateways (Past Spatial and Temporal Gateways) is an IASC-endorsed network, with the scientific goal to understand and reconstruct Arctic environmental changes during the period preceding instrumental records and across decadal to millennial timescales. The focus of the six-year programme is on the nature and significance of Arctic spatial and temporal gateways, with an emphasis on the transistions between major Late Cenozoic climate events such as interglacial to full glacial and full glacial to deglacial states, as well as more recent Holocene fluctuations.

Description / Table of Contents: This volume presents papers on the use of micro-XRF core scanners in palaeoenvironmental research. It contains a broad ranging view of instrument capability and points to future developments that will help contribute to higher precision elemental data and faster core analysis. Readers will find a diverse range of research by leading experts that have used micro-XRF core scanners in a wide range of scientific applications. The book includes specific application papers reporting on the use of XRF core scanners in a variety of marine, lacustrine, and pollution studies. In addition, coverage also examines practical aspects of core scanner usage, data optimisation, and data calibration and interpretation. In a little over a decade, micro-XRF sediment core scanners have made a substantive contribution to palaeoenvironmental research. Their impact is based on their ability to rapidly, non-destructively, and automatically scan sediment cores. Not only do they rapidly provide important proxy data without damaging samples, but they can obtain environmental data at decadal, annual, and even sub-annual scales. This volume will help both experienced and new users of these non-destructive core scanners take full advantage of one of the most powerful geochemical screening tools in the environmental scientist's toolbox

Description / Table of Contents: The present volume of the "Report of the Complex Antarctic Expedition of the Academy of Sciences of the U.S.S.R." contains the account of the work of the marine expedition (the first trip). In this volume the aims and problems of the expedition are given. The special section of the volume is devoted to the coditions in which the research ship "Ob" was sailing from Kaliningrad to the Antarctic, to the search of a place for the setting up of the observatory "Mirny". The brief characteristic of the weather conditions during the sailing and anchorage of the "Ob" in Farr Bay and near Mirny is given in this volume. The main sections of the first volume contain the materials of the scientific research work of the marine expedition. During the period from 30.11.55 to 8.07.56 the "Ob" passed 33325 miles. Passing scientific observations were being done almost continuously. During the period from 29.02.56 (departure from Mirny) to 8.06.56 (arrival to Aden Bay) on the 15700 mile traverse the marine expedition carried out complex explorations on the IGY programme at 156 deep-water oceanographic stations. The volume contains the materials of the scientific research works on aerology, meteorology and actionometry, hydrology and hydrochemistry (physical and chemical characteristics of water mass, currents, colour and transparency of water, wave characteristic, quantity and drift of ice), marine geology (relief of the bottom, ground accumulations, suspension material in the sea water, seismo-acoustic investigations), geophysics (measurements of gravity and electricity in ocean), hydrography (geodesic, astronomoic observations and navigation ensuring of the trip), hydrobiology (plankton, benthos, fishes, marine mammalia and birdes). It is necessary to note, that the conclusions from the scientific research works have the preliminary character, because they are based on the first processing of the materials during the period of the trip.
