Ever since Albert Einstein's general theory of relativity burst upon the world in 1915 some of the most brilliant minds of our century have sought to decipher the mysteries bequeathed by that theory, a legacy so unthinkable in some respects that even Einstein himself rejected them. Which of these bizarre phenomena, if any, can really exist in our universe? Black holes, down which anything can fall but from which nothing can return; wormholes, short spacewarps connecting regions of the cosmos; singularities, where space and time are so violently warped that time ceases to exist and space becomes a kind of foam; gravitational waves, which carry symphonic accounts of collisions of black holes billions of years ago; and time machines, for traveling backward and forward in time. Kip Thorne, along with fellow theorists Stephen Hawking and Roger Penrose, a cadre of Russians, and earlier scientists such as Oppenheimer, Wheeler and Chandrasekhar, has been in the thick of the quest to secure answers. n this masterfully written and brilliantly informed work of scientific history and explanation, Dr. Thorne, the Feynman Professor of Theoretical Physics at Caltech, leads his readers through an elegant, always human, tapestry of interlocking themes, coming finally to a uniquely informed answer to the great question: what principles control our universe and why do physicists think they know the things they think they know?
Stromatolites are the most intriguing geobiological structures of the entire earth history since the beginning of the fossil record in the Archaean. Stromatolites and microbialites are interpreted as biosedimentological remains of biofilms and microbial mats. These structures are important environmental and evolutionary archives which give us information about ancient habitats, biodiversity, and evolution of complex benthic ecosystems. However, many geobiological aspects of these structures are still unknown or only poorly understood. The present proceedings highlight the new ideas and information on the formation and environmental setting of stromatolites presented at the occasion of the Kalkowsky Symposium 2008, held in G ttingen, Germany.
First published in 1992, this wide-ranging volume features 44 articles from 89 contributors on issues of and solutions to modelling of coastal waters around the world in response to an increasing interest in the development and application of numerical hydraulic models as design and management tools. The contributors advise on areas including tidal current modelling, water quality modelling, sediment transport modelling, wave kinematics and computational methods, along with two keynote articles. The main aim of the conference and its resulting volume was to provide a forum whereby engineers, scientists and planners involved in multi-disciplinary models could collaborate and share their expertise. The counterpart to this book is Hydraulic and Environmental Modelling: Estuarine and River Waters.
Geosphere-biosphere interaction of certain elements and compounds is a major factor in global environmental change. This guide to the role of geographical monitoring in ecosystem modelling contains papers presented at the International Geographical Union Seminar on monitoring geosystems.
Environmental Fluid Mechanics (EFM) studies the motion of air and water at several different scales, the fate and transport of species carried along by these fluids, and the interactions among those flows and geological, biological, and engineered systems. EFM emerged some decades ago as a response to the need for tools to study problems of flow and transport in rivers, estuaries, lakes, groundwater and the atmosphere; it is a topic of increasing importance for decision makers, engineers, and researchers alike. The second edition of the successful textbook "Fluid Mechanics of Environmental Interfaces" is still aimed at providing a comprehensive overview of fluid mechanical processes occurring at the different interfaces existing in the realm of EFM, such as the air-water interface, the air-land interface, the water-sediment interface, the surface water-groundwater interface, the water-vegetation interface, and the water-biological systems interface. Across any of these interfaces mass, momentum, and heat are exchanged through different fluid mechanical processes over various spatial and temporal scales. In this second edition, the unique feature of this book, considering all the topics from the point of view of the concept of environmental interface, was maintained while the chapters were updated and five new chapters have been added to significantly enlarge the coverage of the subject area. The book starts with a chapter introducing the concept of EFM and its scope, scales, processes and systems. Then, the book is structured in three parts with fifteen chapters. Part one, which is composed of four chapters, covers the processes occurring at the interfaces between the atmosphere and the surface of the land and the seas, including the transport of dust and the dispersion of passive substances within the atmosphere. Part two deals in five chapters with the fluid mechanics at the air-water interface at small scales and sediment-water interface, including the advective diffusion of air bubbles, the hyporheic exchange and the tidal bores. Finally, part three discusses in six chapters the processes at the interfaces between fluids and biotic systems, such as transport processes in the soil-vegetation-lower atmosphere system, turbulence and wind above and within the forest canopy, flow and mass transport in vegetated open channels, transport processes to and from benthic plants and animals and coupling between interacting environmental interfaces. Each chapter has an educational part, which is structured in four sections: a synopsis of the chapter, a list of keywords that the reader should have encountered in the chapter, a list of questions and a list of unsolved problems related to the topics covered by the chapter. The book will be of interest to graduate students and researchers in environmental sciences, civil engineering and environmental engineering, (geo)physics, atmospheric science, meteorology, limnology, oceanography, and applied mathematics.
This book presents a collection of papers under the theme of multi-hazard early warning and disaster risks. These were selected from the presentations made at the International Symposium on Tsunami and Multi-Hazard Risks, Early Warning and Community Awareness in supporting implementation of the Sendai Framework for Disaster Risk Reduction 2015-2030. This conference aimed to recognize achievements and to highlight work that still needs to be carried out. The conference promoted collaboration among academia, research institutions and disaster management offices, and further encouraged multidisciplinary and multi-sectoral interaction This International Symposium on Multi-Hazard Early Warning and Disaster Risk Reduction provided an important opportunity to reflect upon our progress to date in tackling disaster risk, but also to consider some of the challenges and opportunities that lay ahead of us. A particular focus of this event wasMulti-Hazard Early Warning. During the negotiations for the Sendai Framework, countries and partners highlighted the need to: 1. Continue to invest in, develop, maintain and strengthen people-centred, end-to-end early warning systems; 2. Promote the application of simple and low cost early warning equipment and facilities; 3. Broaden the dissemination channels for early warning information to facilitate early action. Countries also called for the further development of and investment in effective, nationally compatible, regional multi-hazard early warning mechanisms. To address these needs, global Target (g) of the Sendai Framework was adopted, namely to "substantially increase the availability of and access to multi-hazard early warning systems and disaster risk information and assessments to the people by 2030". As illustrated by recent events in Indonesia, it is also vital to address the challenge of cascading hazards that pose a tsunami risk, and the importance of linking tsunami early warning to a multi-hazard environment. However, moving towards a multi-hazard environment is complex and poses many challenges but can bring significant benefits in terms of efficiencies and also in recognising the links between hazards, such as cascading threats. We very much hope that this book will provide an important platform to address these and other challenges in addressing disaster risk, as well as supporting implementation of the Sendai Framework for Disaster Risk Reduction

The journey to the centre of the earth is a voyage like no other we can imagine. Over 3000 km below the earth's surface an extraordinary inner world the size of Mars awaits us. Dive through the molten iron of the outer core and eventually you will reach a solid sphere - an iron-clad world held within a metal sea and unattached to anything above. At the earth's core is the history of our planet written in temperature and pressure, crystals and minerals ... Our planet appears tranquil from outer space. And yet the arcs of volcanoes, the earthquake zones and the auroral glow rippling above our heads are testimony to something remarkable happening inside ... For thousands of years these phenomena were explained in legend and myth. Only in recent times has the brave new science of seismology emerged. One hundred and fifty years after the extraordinary, imaginative feat of Jules Verne's JOURNEY TO THE CENTRE OF THE EARTH, David Whitehouse embarks on a voyage of scientific discovery into the heart of our world. Seismologists today reveal a planet astonishingly buried within a planet. We watch as supercomputers convert signals from the ground into three-dimensional scans of subterranean continents, visit laboratories where scientists attempt to reproduce the intense conditions at the centre of the Earth, travel down the throat of a volcano, look into the deepest hole ever drilled, and imagine a voyage through enormous crystals of iron. Whitehouse's enthralling journey vividly charts all we are able to understand about the mysteries of the deep Earth. His book encompasses the history of our planet and the latest findings about its inner core, allowing us to embark on an adventure that brings us closer to the enigma of our existence.
Our Ecological Footprint presents a powerful model for measuring humanity's impact on the Earth to reduce the harm we are causing the planet before it's too late. While some people believe we can find a middle ground between environmental conservation and economic development, or that future technological discoveries will solve the problem, the authors warn that our planet's limited resources simply can't support an economic system based on unlimited growth. Our Ecological Footprint offers a valuable tool to help us live more sustainably and safeguard our natural resources for generations to come.

It provides information in an integrated, interdisciplinary manner, stressing case histories. It includes review chapters, illustrations, graphs, tables, and color satellite images that present the results of gravity, geodetic, and seismic surveys and of 3-D sea floor sub-bottom visualizations. The data was obtained using satellites, aircraft, and ships from the Atlantic and Pacific Oceans, the Gulf of Mexico, and the Caribbean Sea.Major topics addressed in these volumes include geophysical methods used to explore for hydrocarbons, advanced radiometric and electrical methods for hard mineral searches, the role of geotechnology and seismic acoustics in overcoming geological hazards in selecting drilling sites and pipeline routes, and remote sensing techniques used to determine the physical properties of hydrocarbons.
This self-contained handbook provides a carefully researched, compact source of key earth science information and data, logically sorted by subject matter, and then cross-referenced. Appealing to both experts and non-experts alike, the book presents earth science and environmental science as closely intertwined. It includes tables of the global distributions of fossil fuels, contrasted by tables of the distribution of non-fossil energy sources. Concise explanations cover the subject matters of geology, geophysics, oceans, atmosphere with attention to environmental implications and resources.
For any government agency, the distribution of available resources among problems or programs is crucially important. Agencies, however, typically lack a self-conscious process for examining priorities, much less an explicit method for defining what priorities should be. Worst Things First? illustrates the controversy that ensues when previously implicit administrative processes are made explicit and subjected to critical examination. It reveals surprising limitations to quantitative risk assessment as an instrument for precise tuning of policy judgments. The book also demonstrates the strength of political and social forces opposing the exclusive use of risk assessment in setting environmental priorities.
The ancient Greeks called it Gaia; the Romans Terra. We know it simply as Earth, the planet we call home. And what a planet it is. Formed around 4.6 billion years ago from the debris of the big bang and long-dead stars, at first it was nothing special, but somehow it evolved to become the most amazing place in the known Universe. The only living planet we know of, it also has a very unusual moon, a remarkably dynamic surface, a complex atmosphere and a deeply mysterious interior. This is Planet Earth is dedicated to the wonders of Planet Earth. Its past is long and dramatic and its future shrouded in mystery. Yet despite centuries of research, only now are we starting to understand Earth's complexity. ABOUT THE SERIES New Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.
A thought-provoking and invaluable book for anyone who cares about risk communication and management in the 21st century Anna Jung, Director General, European Food Information Council Professor Ragnar L fstedt has once again produced a most interesting book on risk management and trust, well-based on theory and built on empirical findings Mikael Karlsson, President, Swedish Society for Nature Conservation Highlights the difficult balancing task facing risk regulators. Regulatory inaction against real risks can undermine public trust. However, exaggerated responses to risks can also jeopardize regulators credibility. The diverse international case studies developed by Ragnar L fstedt provide guidance for how regulators can navigate these and other frequently competing concerns W. Kip Viscusi, Cogan Professor of Law and Economics, Harvard University, USA In democracies, government policies cannot succeed without public acceptance. Yet complex risk management requires technical expertise. How to reconcile these competing needs? Ragnar L fstedt provocatively challenges recent research claiming that risk managers must engender public trust via deliberative dialogue. He uses four cases studies to argue that the reasons for distrust vary and demand different responses; that in some cases trust can flow from technical competence without public deliberation; and that in others public deliberation can actually aggravate distrust. Trust me: L fstedt s book will add spice to the debate over risk, experts, the public and trust Jonathan B. Wiener, Perkins Professor of Law and Environmental Policy, Duke University, USA We live in post-trust societies, in which public confidence in governments and corporations over health, food and environmental risk is eroding rapidly. Good risk communication can help companies, governments and institutions minimize disputes, resolve issues and anticipate problems. Without such communication, the best policies can become
The world's coastlines represent a myriad of dynamic and constantly changing environments. Heavily settled and intensely used areas, they are of enormous importance to humans and understanding how they are shaped and change is crucial to our future.Introduction to Coastal Processes and Geomorphologybegins by discussing coastal systems and shows how these systems link to the processes examined in detail throughout the book. These include the morphodynamic paradigm, tides, waves and sediment transport. Later chapters explore fluvial deltas, estuaries, beaches and barriers, coastal sand dunes and geologically-influenced coasts such as cliffs, coral reefs and atolls. A new chapter addresses the forward-facing aspect of coastal morphodynamics, including the ways in which coasts respond to rapid climate changes such as present day global warming. Also new to this second edition is a chapter on future coasts which considers the wider effects of coastal change on other important aspects of coastal systems, including ecology, management, socio-cultural activities, built and natural heritage, and archaeology. Case studies using examples from around the world illustrate theory in practice and bring the subject to life. Each chapter starts by outlining the 'aims' and questions at the end allow you to track your progress.
This book is an illustrative introduction to metamorphic rocks as seen in the field, designed for advanced high school to graduate-level earth science and geology students to jump-start their observational skills. In addition to photographs of rocks in the field, there are numerous line diagrams and examples of metamorphic features shown in thin section. The thin section photos are all at a scale and in a context that can be related to views seen in the field through a hand lens.
Time-variable exposure profiles of pesticides are more often the rule than exception in the surface waters of agricultural landscapes. There is, therefore, a need to adequately address the uncertainties arising from time-variable exposure profiles in the aquatic risk assessment procedure for pesticides. Linking Aquatic Exposure and Effects: Risk Assessment of Pesticides provides guidance and recommendations for linking aquatic exposure and ecotoxicological effects in the environmental assessment of agricultural pesticides. Leading international scientists share their expertise in aquatic exposure assessment, aquatic ecotoxicology, and the risk assessment and management of plant protection products. The book incorporates the tools and approaches currently available for assessing the environmental risks of time-variable exposure profiles of pesticides. It also discusses the science behind these techniques. This volume covers the extrapolation techniques, including models that address the environmental fate, toxicokinetics, toxicodynamics, and ecological effects, for performing accurate aquatic environmental risk assessments of pesticides. It explains how to link aquatic exposure and effects in the risk assessment procedure for plant protection products.
The over-enrichment of surface water bodies with phosphorus compounds can lead to eutrophication resulting in reduced photosynthetic activity, oxygen depletion, production of toxic compounds and, ultimately, loss of plant and animal species. Due to relatively high removal efficiency, economy and environmentally-friendly operation, enhanced biological phosphorus removal (EBPR) in activated sludge wastewater treatment systems is a popular technology to control and prevent eutrophication in surface water bodies. EBPR can be implemented by promoting the enrichment of the system with polyphosphate-accumulating organisms (PAO). However, EBPR process may suffer of instability and unreliability experiencing process upsets, deterioration and even failure. Among other factors, the appearance of glycogen-accumulating organisms (GAO), which compete with PAO, has been hypothesized to be the main cause of deterioration of the EBPR process performance. In this research, the effects of key environmental and operating conditions influencing the PAO-GAO competition were addressed through undertaking different studies at both lab- and full-scale and by applying mathematical modelling. It contributes to get a better understanding about the factors affecting the PAO-GAO competition and, thus, the stability and reliability of the EBPR process in activated sludge systems. The findings obtained in this research may prove useful towards optimization of full-scale EBPR plants.

A broad and comprehensive exploration of the role of the ecological sciences in sustainability for undergraduates.The urgent quest for more sustainable patterns of development has placed new and difficult demands on both scientists and policy makers as they seek to establish more informed and effective policy processes and management regimes in the the face of pervasive uncertainty. Written by an international group of authors from a range of disciplines - ecology, geography, law, policy analysis and others - the chapters explore issues of scientific legitimacy, public participation, non-governmental organisations, inter-sectoral communication and pragmatic public policy across a wide range of ecosystem management contexts.
Terrestrial Biosphere tries to pose the questions which underlie the many-sided debate of how to respond to and influence change: How should we view nature? What do we do for the best - how should we act - what are we trying to achieve and what should we be guided by?In doing so the book introduces and attempts to analyse not only scientific aspects of the debate but also cultural attitudes and values: the notions of ecosystem stability are now challenged and it is also clear that ecosystems are renewable but not repeatable. It finds that prescriptive 'solutions' based on current constructs may not be adequate. Feeling that analysis should lead to advocacy, the author believes that if we can't improve predictability, we have to increase adaptability which means that ecological and social capacity building should be advocated. This is seen in terms of concepts, institutions, attitudes and values which allow for a plurality of meanings and which can cope with surprise and unforeseen change - and which also facilitates responses to change.
This book deals with a class of basic deformations in Asymmetric Continuum Theory. It describes molecular deformations and transport velocities in fluids, strain deformations in solids as well as the molecular transport, important in fracture processes. In solids, a separate problem relates to the displacements; their recording, e.g., by means of the seismometers, proves only the existence of the displacement derivatives and not a real displacement. However, the molecular displacements and new fracture criterion including the defect distributions and induced strains are defined in the book too. In fluids, the transport velocities and molecular strains describe the motion processes. The vortex motions are defined by means of the rotational transport; this approach leads to more complicated problems, like the turbulence phenomena. The interaction processes, including the electric and magnetic fields, and some thermodynamical problems and quantum theory analogies help to understand the extreme processes
This textbook presents a comprehensive examination of environmental science and ecotoxicology for undergraduate students. The material provides sufficient related background information leading to a competency to clearly understand ecotoxicology concepts and topics.
