    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 will take an evidence-based approach to current knowledge about biomolecules and their place in our lives, inviting readers to explore how we know what we know, and how current gaps in knowledge may influence the way we approach the information. Biomolecular science is increasingly important in our everyday life, influencing the choices we make about our diet, our health, and our wellness. Often, however, information about biomolecular science is presented as a list of immutable facts, discouraging critical thought. The book will introduce the basic tools of structural biology, supply real-life examples, and encourage critical thought about aspects of biology that are still not fully understood.

    In: Theory and applications of transport in porous media, Volume 27
    Description / Table of Contents: This book treats the mechanics of porous materials infiltrated with a fluid (poromechanics), focussing on its linear theory (poroelasticity). Porous materials from inanimate bodies such as sand, soil and rock, living bodies such as plant tissue, animal flesh, or man-made materials can look very different due to their different origins, but as readers will see, the underlying physical principles governing their mechanical behaviors can be the same, making this work relevant not only to engineers but also to scientists across other scientific disciplines. Readers will find discussions of physical phenomena including soil consolidation, land subsidence, slope stability, borehole failure, hydraulic fracturing, water wave and seabed interaction, earthquake aftershock, fluid injection induced seismicity and heat induced pore pressure spalling as well as discussions of seismoelectric and seismoelectromagnetic effects. The work also explores the biomechanics of cartilage, bone and blood vessels. Chapters present theory using an intuitive, phenomenological approach at the bulk continuum level, and a thermodynamics-based variational energy approach at the micromechanical level. The physical mechanisms covered extend from the quasi-static theory of poroelasticity to poroelastodynamics, poroviscoelasticity, porothermoelasticity, and porochemoelasticity. Closed form analytical solutions are derived in details. This book provides an excellent introduction to linear poroelasticity and is especially relevant to those involved in civil engineering, petroleum and reservoir engineering, rock mechanics, hydrology, geophysics, and biomechanics.

    Description / Table of Contents: This book highlights perspectives, insights, and data in the coupled fields of aquatic microbial ecology and biogeochemistry when viewed through the lens of collaborative duos - dual career couples. Their synergy and collaborative interactions have contributed substantially to our contemporary understanding of pattern, process and dynamics. This is thus a book by dual career couples about dual scientific processes. The papers herein represent wide-ranging topics, from the processes that structure microbial diversity to nitrogen and photosynthesis metabolism, to dynamics of changing ecosystems and processes and dynamics in individual ecosystems. In all, these papers take us from the Arctic to Africa, from the Arabian Sea to Australia, from small lakes in Maine and Yellowstone hot vents to the Sargasso Sea, and in the process provide analyses that make us think about the structure and function of all of these systems in the aquatic realm. This book is useful not only for the depth and breadth of knowledge conveyed in its chapters, but serves to guide dual career couples faced with the great challenges only they face. Great teams do make great science

    Description / Table of Contents: This title brings to light the discoveries and insights into the lives of many marine species made possible over the last decade by passive acoustic recorders (PAR). Pop-ups, ARF, HARP, EAR, Bprobe, C-POD Atag, and Dtag are the acronyms of some of the many PARs that have changed our understanding of how marine animals live and strive in the ocean. Various types of PARs are used by different investigators in different areas of the world. These recorders have accumulated copious amounts of very important data, unveiling previously unknown information about large marine animals. Temporal, seasonal and spatial distribution patterns have been uncovered for many marine species. There have been many discoveries, new understandings and insights into how these animals live in and utilize the ocean and the importance of acoustics in their lives. Listening Within the Ocean summarizes these important discoveries, providing both a valuable resource for researchers and enjoyable reading for non-professionals interested in marine life.

    Description / Table of Contents: This report examines the scientific basis for the use of remotely sensed data, particularly Normalized Difference Vegetation Index (NDVI), primarily for the assessment of land degradation at different scales and for a range of applications, including resilience of agro-ecosystems. Evidence is drawn from a wide range of investigations, primarily from the scientific peer-reviewed literature but also non-journal sources. The literature review has been corroborated by interviews with leading specialists in the field. The report reviews the use of NDVI for a range of themes related to land degradation, including land cover change, drought monitoring and early warning systems, desertification processes, greening trends, soil erosion and salinization, vegetation burning and recovery after fire, biodiversity loss, and soil carbon. This SpringerBrief also discusses the limits of the use of NDVI for land degradation assessment and potential for future directions of use. A substantial body of peer-reviewed research lends unequivocal support for the use of coarse-resolution time series of NDVI data for studying vegetation dynamics at global, continental and sub-continental levels. There is compelling evidence that these data are highly correlated with biophysically meaningful vegetation characteristics such as photosynthetic capacity and primary production that are closely related to land degradation and to agroecosystem resilience.

    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: 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.

    Description / Table of Contents: 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…

    Description / Table of Contents: This book is a useful guide for researchers in ecology and earth science interested in the use of accelerator mass spectrometry technology. The development of research in radiocarbon measurements offers an opportunity to address the human impact on global carbon cycling and climate change. Presenting radiocarbon theory, history, applications, and analytical techniques in one volume builds a broad outline of the field of radiocarbon and its emergent role in defining changes in the global carbon cycle and links to climate change. Each chapter presents both classic and cutting-edge studies from different disciplines involving radiocarbon and carbon cycling. The book also includes a chapter on the history and discovery of radiocarbon, and advances in radiocarbon measurement techniques and radiocarbon theory. Understanding human alteration of the global carbon cycle and the link between atmospheric carbon dioxide levels and climate remains one of the foremost environmental problems at the interface of ecology and earth system science. Many people are familiar with the terms ‘global warming’ and ‘climate change’, but fewer are able to articulate the science that support these hypotheses. This book addresses general questions such as: what is the link between the carbon cycle and climate change; what is the current evidence for the fate of carbon dioxide added by human activities to the atmosphere, and what has caused past changes in atmospheric carbon dioxide? How can the radiocarbon and stable isotopes of carbon combined with other tools be used for quantifying the human impact on the global carbon cycle?

    Description / Table of Contents: The book presents recent research on marine ecology in different parts of the world. It aims to shed light on relevant topics for budding marine ecologists. The “blue soup” of Planet Earth, which comprises both biotic and abiotic components, is essential to keeping the wheel of civilization running. Four major ecosystem service categories have been identified within this context, namely provisioning services such as water, food, mangrove timber, honey, fish, wax, fuel wood, fodder and bioactive compounds from marine and estuarine flora and fauna; regulating services such as the regulation of climate, coastal erosion, coral bleaching and pollution;cultural services encompassing recreational (tourism), spiritual and other non-material benefits; and supporting services such as nutrient cycling and photosynthesis. These valuable services are obtained from various resources that must be conserved for the sake of humanity. This book presents data for each resource type, not just in the form of a simple description, but also through case studies that resulted from several research projec ts and pilot programs carried out in different parts of the world. Statistical tools were also used to critically analyze the influence of relevant hydrological parameters on the biotic community. Advanced research in marine and estuarine ecology is based on the use of sophisticated instruments, sampling precision, statistical tools, etc., which have also been highlighted in the book.

    Description / Table of Contents: This book seeks to enhance the cultural dimension of sustainable development and particularly focuses on minor historic centers and their natural and rural landscapes. In a society becoming ever more globalized, without territorial restrictions in the production of goods and able to reproduce in China the goods and product characteristic of South American crafts (to mention just two extremes), the only element that can still be contextualized is heritage identity: the result of close integration between cultural assets, intangible assets and settled communities. Thus, heritage identity is one of the few elements, together with natural resources, which has the potential for economic development that is still firmly rooted in places and local populations.These towns are often the centerpiece of urban landscapes and geographical areas with original features, not always but often as individual places within networks of minor historical centers linked by shared history, traditions and/or natural elements (rivers, forests, river systems or other natural elements). They are outside the major tourist networks, even if now there is a budding interest in the touristic exploitation of these environments. So, they are the right places to pursue a sustainable and local development with a cultural perspective. This book is a product of the VIVA_EASTPART project (Valorisation and Improving of management of Small Historic Centres in the eastern PARTnership region), under the EU-funded “ENPI Eastern Partnership” program. It complements the more practically-focused work that is in production from this group, more focused on empirical approaches to the development of minor historic centers of the nations involved. Though the book has been influenced by this research and working experience, the authors are solely responsible for the content and opinions presented.
