This book provides a snapshot of representative modeling analyses of coastal hypoxia and its effects. Hypoxia refers to conditions in the water column where dissolved oxygen falls below levels that can support most metazoan marine life (i.e., 2 mg O2 l-1). The number of hypoxic zones has been increasing at an exponential rate since the 1960s; there are currently more than 600 documented hypoxic zones in the estuarine and coastal waters worldwide. Hypoxia develops as a synergistic product of many physical and biological factors that affect the balance of dissolved oxygen in seawater, including temperature, solar radiation, wind, freshwater discharge, nutrient supply, and the production and decay of organic matter. A number of modeling approaches have been increasingly used in hypoxia research, along with the more traditional observational and experimental studies. Modeling is necessary because of rapidly changing coastal circulation and stratification patterns that affect hypoxia, the large spatial extent over which hypoxia develops, and limitations on our capabilities to directly measure hypoxia over large spatial and temporal scales. This book consists of 15 chapters that are broadly organized around three main topics: (1) Modeling of the physical controls on hypoxia, (2) Modeling of biogeochemical controls and feedbacks, and, (3) Modeling of the ecological effects of hypoxia. The final chapter is a synthesis chapter that draws generalities from the earlier chapters, highlights strengths and weaknesses of the current state-of-the-art modeling, and offers recommendations on future directions.
In this spirit, the ATMSS International Workshop "Advances in Laboratory Testing & Modelling of Soils and Shales" (Villars-sur-Ollon, Switzerland; 18-20 January 2017) has been organized to promote the exchange of ideas, experience and state of the art among major experts active in the field of experimental testing and modelling of soils and shales. The Workshop has been organized under the auspices of the Technical Committees TC-101 "Laboratory Testing", TC-106 "Unsaturated Soils" and TC-308 "Energy Geotechnics" of the International Society of Soil Mechanics and Geotechnical Engineering. This volume contains the invited keynote and feature lectures, as well as the papers that have been presented at the Workshop. The topics of the lectures and papers cover a wide range of theoretical and experimental research, including unsaturated behaviour of soils and shales, multiphysical testing of geomaterials, hydro-mechanical behaviour of shales and stiff clays, the geomechanical behaviour of the Opalinus Clay shale, advanced laboratory testing for site characterization and in-situ applications, and soil - structure interactions.
This book describes the second phase of the Qinghai-Tibetan railway construction project and is the first technological book discussing the geological routing of the Qinghai-Tibetan railway project on the "roof of the world." Based on practical experience of railway construction work, it provides a substantial number of examples with detailed descriptions and conclusions. The complex geological environment of the Qinghai-Tibetan railway as well as the selection and optimization of the route are illustrated vividly and clearly with quotes, figures, photos, and tables. Connecting Golmud and Lhasa, it has a total length of 1142 km and at the Tanggula Pass has an altitude of 5072m-higher than any other in the world. A 960 km section is on a plateau at altitudes above 4000 m, and 550 km are in the permafrost region, making it the world's longest and highest railway in the permafrost plateau region. The book is a model for the integration of theory and practice, making it a valuable reference source for civil engineering professionals working in geological routing in permafrost plateau regions, active fault zones, meizoseismal areas, nature reserves, and regions with geohazards such as steep slopes, sand and snow drifts and geothermal hazards.
This book presents a selection of the best papers from the HEaRT 2013 conference, held in Cosenza, Italy, which provided a valuable forum for engineers and architects, researchers and educators to exchange views and findings concerning the technological history, construction features and seismic behavior of historical timber-framed walls in the Mediterranean countries. The topics covered are wide ranging and include historical aspects and examples of the use of timber-framed construction systems in response to earthquakes, such as the gaiola system in Portugal and the Bourbon system in southern Italy; interpretation of the response of timber-framed walls to seismic actions based on calculations and experimental tests; assessment of the effectiveness of repair and strengthening techniques, e.g., using aramid fiber wires or sheets; and modelling analyses. In addition, on the basis of case studies, a methodology is presented that is applicable to diagnosis, strengthening and improvement of seismic performance and is compatible with modern theoretical principles and conservation criteria. It is hoped that, by contributing to the knowledge of this construction technique, the book will help to promote conservation of this important component of Europe's architectural heritage.
This book presents a collection of selected reviews from PLMMP 2018 that address modern problems in the fields of liquids, solutions and confined systems, critical phenomena, as well as colloidal and biological systems.

This book is a unified, condensed, and simplified version of the recently issued twin volumes, Fundamentals of Soil Physics and Applications of Soil Physics. Nonessential topics and complexities have been deleted, and little prior knowledge of the subject is assumed. An effort has been made to provide an elementary, readable, and self-sustaining description of the soil's physical properties and of the manner in which these properties govern the processes taking place in the field. Consideration is given to the ways in which the soil's processes can be influenced, for better or for worse, by man. Sample problems are provided in an attempt to illustrate how the abstract principles embodied in mathematical equations can be applied in practice. The author hope that the present version will be more accessible to students than its precursors and that it might serve to arouse their interest in the vital science of soil physics.
Our understanding of the rheological and seismic properties of the Earth's interior relies on interpreting geophysical observations using mineral physics data. The complexity of natural materials complicates these interpretations, but here the key features of such materials in controlling the attenuation of seismic waves are determined by a set of careful experiments. This thesis clearly explains how dynamic mechanical spectroscopy has been used to determine the visco-elastic properties of igneous and sedimentary rocks containing geological fluids. These experiments highlight, for the first time, the importance of mineral and rock microstructures as controls on geophysical properties of solids, particularly near the melting point. The results have impacts in areas ranging from volcanic processes, through the structure of the deep Earth, to fluid-saturated porous media.
Soils, invaluable indicators of the nature and history of the physical and human landscape, have strongly influenced the cultural record left to archaeologists. Not only are they primary reservoirs for artifacts, they often encase entire sites. And soil-forming processes in themselves are an important component of site formation, influencing which artifacts, features, and environmental indicators (floral, faunal, and geological) will be destroyed and to what extent and which will be preserved and how well. In this book, Holliday will address each of these issues in terms of fundamentals as well as in field case histories from all over the world. The focus will be on principles of soil geomorphology, soil stratigraphy, and soil chemistry and their applications in archaeological research.

International bestseller Tom Phillips (Humans; Truth; Conspiracy) is back with a fascinating and hilarious look at armageddon through the ages Do you feel like we're living in the end times? Does it seem like everything is on fire, and one disaster follows another? Here's a small comfort: you're not the first to feel that way. If there's one thing that people throughout history have agreed on, it's that history wasn't going to be around for much longer. This book is about the apocalypse, and how humans have always believed it to be very f*cking nigh. Across thousands of years, we'll meet weird cults, failed prophets and mass panics, holy warriors leading revolts in anticipation of the last days, and suburbanites waiting for aliens to rescue them from a doomed Earth. We'll journey back to the 'worst period to be alive', as the world reeled from a simultaneous pandemic and climate crisis. And we'll look to the future to ask the unnerving question: how might it all end? But it's also a book about how we live in a world where catastrophe is always looming - whether it's a madman with a nuclear button or the slow burn of environmental collapse. Because when we talk about the end of the world, what we really mean is the end of our world. Our obsession with doomsday is really about change: our fear of it, and our desire for it, and how - ultimately - we can find hope in it.

This new volume on boron isotope geochemistry offers review chapters summarizing the cosmochemistry, high-temperature and low-temperature geochemistry, and marine chemistry of boron. It also covers theoretical aspects of B isotope fractionation, experiments and atomic modeling, as well as all aspects of boron isotope analyses in geologic materials using the full range of solutions and in-situ methods. The book provides guidance for researchers on the analytical and theoretical aspects, as well as introducing the various scientific applications and research fields in which boron isotopes currently play a major role. The last compendium to summarize the geochemistry of boron and address its isotope geochemistry was published over 20 years ago (Grew &Anovitz, 1996, MSA Review, Vol.33), and there have since been significant advances in analytical techniques, applications and scientific insights into the isotope geochemistry of boron. This volume in the "Advances in Isotope Geochemistry" series provides a valuable source for students and professionals alike, both as an introduction to a new field and as a reference in ongoing research.

Despite growing evidence of geothermic activity under America's
first and foremost national park, it took geologists a long time to
realize that there was actually a volcano beneath Yellowstone. And
then, why couldn't they find the caldera or crater? Because, as an
aerial photograph finally revealed, the caldera is 45 miles wide,
encompassing all of Yellowstone. What will happen, in human terms,
when it erupts?

Historically, it is the land of the bison. But the land across which these powerful herds once thundered has been transformed. We know it today by such names as Montana, Wyoming, Dakota, western Iowa, and Nebraska--but it is really buffalo country, the land of the big sky rivers. This book is a tale of two rivers, a history of the majestic Missouri and how it was once wedded to the Yellowstone. Though quite different today--one dammed into reservoirs, the other unregulated with a semblance of wildness--they were once linked ecologically, geographically, and historically. Then in the twentieth century, Euro-Americans dismantled many of these connections and attempted to uncouple the streams. Viewing the rivers and their surrounding lands as a living system, Robert Kelley Schneiders focuses on four components within the Upper Missouri bioregion--the Missouri River valley, the Yellowstone River valley, Homo sapiens, and bison--to show the significance of their interaction over the past two hundred years. To frame his story, Schneiders goes back to the nineteenth-century journals of fur traders and settlers, and in the record of flora, fauna, floods, and human activity he finds evidence of rapid and disruptive change. Bison once had the greatest influence on the land, and Schneiders depicts an original bison and Indian trail network on which were overlaid the first forts and towns and then the railroads, highways, and reservoirs that reconfigured the region forever. Schneiders explains how these geographical constructs interacted with larger demographic and economic trends in the twentiety-century West, as dams and their resultant reservoirs enhanced the federal presence in the Dakotas andeastern Montana. He describes human encroachment on the rivers and tells why the Corps of Engineers dammed the Missouri but spared the Yellowstone. The engineers and their backers have so completely engineered the Missouri that few people today think of it as anything other than water. But we can reestablish our bonds to the river if we decide to let it flow once again, argues Schneiders. Removing the dams on the Missouri is the first step toward reasserting localism and grassroots democracy. In what was once buffalo country, a dormant ecology awaits rebirth. A major work of environmental history, "Big Sky Rivers offers a challenging vision for the future of the Upper Missouri bioregion.
Data assimilation (DA) has been recognized as one of the core techniques for modern forecasting in various earth science disciplines including meteorology, oceanography, and hydrology. Since early 1990s DA has been an important s- sion topic in many academic meetings organized by leading societies such as the American Meteorological Society, American Geophysical Union, European G- physical Union, World Meteorological Organization, etc. nd Recently, the 2 Annual Meeting of the Asia Oceania Geosciences Society (AOGS), held in Singapore in June 2005, conducted a session on DA under the - tle of "Data Assimilation for Atmospheric, Oceanic and Hydrologic Applications." nd This rst DA session in the 2 AOGS was a great success with more than 30 papers presented and many great ideas exchanged among scientists from the three different disciplines. The scientists who participated in the meeting suggested making the DA session a biennial event. th Two years later, at the 4 AOGS Annual Meeting, Bangkok, Thailand, the DA session was of cially named "Sasaki Symposium on Data Assimilation for At- spheric, Oceanic and Hydrologic Applications," to honor Prof. Yoshi K. Sasaki of the University of Oklahoma for his life-long contributions to DA in geosciences.
Presents a comprehensive synopsis of the current state of cosmic rays, their modulation and their effects in the Earth's atmosphere. Leading scientists in the field assess the current state of our understanding of the spatial and temporal variations of galactic and anomalous cosmic rays in the Heliosphere, and their relation to effects of the Sun. The main objective is to understand the spatial and temporal variation of galactic and anomalous cosmic rays in the light of recent observations, theory and modeling by identifying the key mechanism(s) of cosmic ray modulation and how changes on the Sun relate to changes in the observed characteristics of cosmic rays in the Heliosphere; examining the current long-lasting solar minimum and understand its implications for solar-cycle variations and long-term variations; and interpreting the long-term variations of cosmogenic radionuclides in terms of solar variability and climate change on Earth. This volume is aimed at graduate students active in the fields of solar physics, space science, and cosmic ray physics. Originally published in Space Science Reviews journal, Vol. 176/1-4, 2013.
