Before the drought of the early twenty-first century, the dry
benchmark in the American plains was the Dust Bowl of the 1930s.
But in this eye-opening work, Kevin Z. Sweeney reveals that the
Dust Bowl was only one cycle in a series of droughts on the U.S.
southern plains. Reinterpreting our nation's nineteenth-century
history through paleoclimatological data and firsthand accounts of
four dry periods in the 1800s, Prelude to the Dust Bowl
demonstrates the dramatic and little-known role drought played in
settlement, migration, and war on the plains. Stephen H. Long's
famed military expedition coincided with the drought of the 1820s,
which prompted Long to label the southern plains a ""Great American
Desert"" - a destination many Anglo-Americans thought ideal for
removing Southeastern Indian tribes to in the 1830s. The second dry
trend, from 1854 to 1865, drove bison herds northeastward,
fomenting tribal warfare, and deprived Civil War armies in Indian
Territory of vital commissary. In the late 1880s and mid-1890s, two
more periods of drought triggered massive outmigration from the
southern plains as well as appeals from farmers and congressmen for
federal famine relief, pleas quickly denied by President Grover
Cleveland. Sweeney's interpretation of familiar events through the
lens of drought lays the groundwork for understanding why the U.S.
government's reaction to the Dust Bowl of the 1930s was such a
radical departure from previous federal responses. Prelude to the
Dust Bowl provides new insights into pivotal moments in the
settlement of the southern plains and stands as a timely reminder
that drought, as part of a natural climatic cycle, will continue to
figure in the unfolding history of this region.
This book describes selected problems in contemporary spectroscopy
in the context of quantum mechanics and statistical physics. It
focuses on elementary radiative processes involving atomic
particles (atoms, molecules, ions), which include radiative
transitions between discrete atomic states, the photoionization of
atoms, photorecombination of electrons and ions, bremsstrahlung,
photodissociation of molecules, and photoattachment of electrons to
atoms. In addition to these processes, the transport of resonant
radiation in atomic gases and propagation of infrared radiation in
molecular gases are also considered. The book subsequently
addresses applied problems such as optical pumping, cooling of
gases via laser resonance radiation, light-induced drift of gas
atoms, photoresonant plasma, reflection of radio waves from the
ionosphere, and detection of submillimeter radiation using Rydberg
atoms. Lastly, topical examples in atmospheric and climate change
science are presented, such as lightning channel glowing, emission
of the solar photosphere, and the greenhouse phenomenon in the
atmospheres of the Earth and Venus. Along with researchers, both
graduate and undergraduate students in atomic, molecular and
atmospheric physics will find this book a useful and timely guide.
The present book provides guidance to understanding complicated
coupled processes based on the experimental data available and
implementation of developed algorithms in numerical codes. Results
of selected test cases in the fields of closed-form solutions
(e.g., deformation processes), single processes (such as
groundwater flow) as well as coupled processes are presented. It is
part of the OpenGeoSys initiative - an open source project to share
knowledge and experience in environmental analysis and scientific
computation with the community.
This book is a critical appraisal of the status of the so-called
Climate Sciences (CS). These are contributed by many other basic
sciences like physics, geology, chemistry and as such employ
theoretical and experimental methods. In the last few decades most
of the CS have been identified with the global warming problem and
numerical models have been used as the main tool for their
investigations. The produced predictions can only be partially
tested against experimental data and may represent one of the
reasons CS are drifting away from the route of the scientific
method. On the other hand the study of climate faces many other
interesting and mostly unsolved problems (think about ice ages)
whose solution could clarify how the climatic system works. As for
the global warming, while its existence is largely proved,
scientifically it can be solved only with a large experimental
effort carried out for a few decades. Problems can arise when not
proved hypotheses are adopted as the basis for public policy
without the recognition that they may be on shaky ground. The
strong interactions of the Global Warming (GW) with the society
create another huge problem of political nature for the CS. The
book argues that the knowledge gained so far on the specific GW
problem is enough for the relevant political decisions to be taken
and that Climate Science should resume the study of the climate
system with appropriate means and methods. The book introduces the
most relevant concepts needed for the discussion in the text or in
appropriate appendices and it is directed to the general public
with upper undergraduate background. Each chapter closes with a
debate between a climate scientist and a humanist to reflect the
discussions between climate science and philosophy or climate
scientists and society.

This book gives background information why shale formations in the
world are important both for storage capacity and enhanced gas
recovery (EGR). Part of this book investigates the sequestration
capacity in geological formations and the mechanisms for the
enhanced storage rate of CO2 in an underlying saline aquifer. The
growing concern about global warming has increased interest in
geological storage of carbon dioxide (CO2). The main mechanism of
the enhancement, viz., the occurrence of gravity fingers, which are
the vehicles of enhanced transport in saline aquifers, can be
visualized using the Schlieren technique. In addition high pressure
experiments confirmed that the storage rate is indeed enhanced in
porous media. The book is appropriate for graduate students,
researchers and advanced professionals in petroleum and chemical
engineering. It provides the interested reader with in-depth
insights into the possibilities and challenges of CO2 storage and
the EGR prospect.
Understanding Geology through Maps guides young professional
geologists and students alike in understanding and interpreting the
world's dynamic and varying geological landscapes through the
liberal use of visual aids including figures, maps, and diagrams.
This highly visual reference introduces the skills of interpreting
a geological map and relating it to the morphology of the most
important types of geological structure. Thoroughly revised, and
with more international examples, it is ideal for use by students
with a minimum of tutorial supervision. Maps of geological
structures provide all of the realism of a survey map without the
huge amount of data often present, so readers can develop or hone
their skills without becoming overwhelmed or confused. In
particular, emphasis is placed throughout on developing the skill
of three-dimensional visualization so important to geologists.
How much has human history been influenced by the earth and its
processes? This volume in the Science 101 series describes how both
slow changes and rapid, violent, ones have impacted the development
of civilizations throughout history. Slow changes include
variations in climate, progressive development of types of tools
and sources of energy, and changes in the types of food that people
consume. Violent changes include volcanic eruptions such as the one
at Toba 75,000 years ago, which may have caused diversification of
people into different races, and the eruption of Santorini in 1640
BC, which may have destroyed Minoan civilization. Other disasters
are Hurricane Katrina in 2005 and the tsunami in the Indian Ocean
in 2004. Earth Science and Human History 101 describes basic
principles of geology and shows how the earth affected history and
is affecting present events. The volume has four sections:
BLProcesses in the atmosphere, oceans, and rivers BLPlate tectonics
BLThe conflict between the evidence for evolution during the long
history of the earth and the beliefs of creationists BLResources
and the environment The volume includes a glossary, numerous
illustrations, and a bibliography of works useful for further
research.
Great blue herons, yellow birches, damselflies, and beavers are
among the talismans by which Bill Roorbach uncovers a natural
universe along the stream that runs by his house in Farmington,
Maine. Populated by an oddball cast of characters to whom Roorbach
("The Professor") and his family might always be considered
outsiders, this book chronicles one man's determined
effort-occasionally with hilarious results-to follow his stream to
its elusive source. Acclaimed essayist and award-winning fiction
writer Bill Roorbach uses his singular literary gifts to inspire us
to laugh, love, and experience the wonder of living side by side
with the natural world.
This atlas gives a comprehensive account on the benthic
foraminiferal fauna in the China Seas, especially on the Bohai and
the Yellow Seas. Details of about 183 species, subjected to 5
orders, 52 families and 92 genera are included. For each species
there is a brief description of the morphological characteristics,
synonymised names, measurements and geographical distribution
worldwide, as well as a top-level elegant plate illustrated the
fossil and live specimens. It could be used as a reference book for
researchers working at marine biology, marine geology,
micropaleontology, paleoceanography, paleobiology and related
fields.
This volume contains reviews on different aspects of human, animal
and plant bioclimatology; the mechanisms linking human melanoma
with radiation from both the sun and artificial sources; field and
experimental studies on the health of farm animals in adverse
climatic environments and the impact of climatic extremes on
airborne disease organisms and their hosts' defense mechanisms;
measurement techniques used in plant bioclimatology, including
thermoelectric methods of measuring sap flow and transpiration in
plants, remote sensing techniques: the use of lasers in both
spectrofluorometry, and the study of the geometrical structure of
plant canopies and the use of radar mounted in aircraft and
satellites to monitor forest size and state.
This book provides a comprehensive description of the
volcanological, petrological and geochemical features of the Poas
Volcano (Costa Rica), one of the most active volcanic systems in
Central America and part of the Central America Volcanic Arc
(CAVA). Poas Volcano hosts a unique sulfur lake, which actually is
one of the world's most acidic lakes, and has experienced molten
sulfur eruptions. Past investigations, current monitoring
activities and planned programs of investigation into lessening of
the volcanic hazard are reported here. Specific sections of the
monograph will be devoted to the impact of this volcano on the
social, agricultural and industrial activities in the area. Legends
and popular traditions related to this volcano will be described in
the last chapter to round up a complete scientific review on this
unique volcanic system.
The Integrated Ocean Drilling Program (IODP: 2000-2013) has
provided crucial records of past and present processes and
interactions within and between the biosphere, cryosphere,
atmosphere, hydrosphere and geosphere. Research in IODP encompasses
a wide range of fundamental and applied issues that affect society,
such as global climate change, biodiversity, the origin of life,
natural hazards involving the study of earthquakes processes, and
the internal structure and dynamics of our planet. This compilation
of major findings from the 2003-2013/14 phase of IODP, focusing on
scientific results rather than description of data acquisition and
early inferences, provides invaluable information. Anyone wondering
what scientific drilling can achieve will gain quick understanding
of the range of questions that are uniquely addressed with this
methodology and the ways these data dovetail with other regional
information. The excitement of breakthrough findings that
occasionally accompanies a drilling project will be evident. IODP
obtained unique records from the global ocean basins during the
2003-2013 program phase. This book highlights findings in three
theme areas: Subseafloor life and the marine biosphere; Earth's
changing environments; and Dynamics of the solid Earth. Each core
or borehole log provides a window revealing insights that no other
data achieve.
This book presents the state-of-the-art of optical remote sensing
applied for the generation of marine climate-quality data products,
with contributions by international experts in the field. The
chapters are logically grouped into six thematic parts, each
introduced by a brief overview. The different parts include: i.
requirements for the generation of climate data records from
satellite ocean measurements and additionally basic radiometry
principles addressing terminology, standards, measurement equation
and uncertainties; ii. satellite visible and thermal infrared
radiometry embracing instrument design, characterization and, pre-
and post-launch calibration; iii. in situ visible and thermal
infrared radiometry including overviews on basic principles,
technology and measurements methods required to support satellite
missions devoted to climate change investigations; iv. simulations
as fundamental tools to support interpretation and analysis of both
in situ and satellite radiometric measurements; v. strategies for
in situ radiometry to satisfy mission requirements for the
generation of climate data records; and finally, vi. methods for
the assessment of satellite data products. Fundamentals of
measurement theory are taken through to implementation of practical
ground based radiometers and their application to validate
satellite data used to generate climate data records. This book
presents practical solutions for those involved or contemplating
the validation of optical climate measurements from satellite
instruments.
Geomorphological Fieldwork addresses a topic that always remains
popular within the geosciences and environmental science. More
specifically, the volume conveys a growing legacy of field-based
learning for young geomorphologists that can be used as a student
book for field-based university courses and postgraduate research
requiring fieldwork or field schools. The editors have much
experience of field-based learning within geomorphology and extend
this to physical geography. The topics covered are relevant to
basic geomorphology as well as applied approaches in environmental
and cultural geomorphology. The book integrates a physical-human
approach to geography, but focuses on physical geography and
geomorphology from an integrated field-based geoscience
perspective.
Coal and Peat Fires: A Global Perspective, Volumes 1-4, presents a
fascinating collection of research about prehistoric and historic
coal and peat fires. Magnificent illustrations of fires and
research findings from countries around the world are featured-a
totally new contribution to science. This third of four volumes in
the collection, Coal Fires - Case Studies, examines in detail
specific coal fires chronicled in a number of locations around the
world including Brazil, the Czech Republic, Germany, Malawi,
Poland, Russia, Spain, Tajikistan, the United States, Venezuela,
and others.
Using a series of case studies, the book demonstrates the power of
dynamic analysis as applied to the fossil record. Written in an
engaging and informative style, Dynamic Paleontology outlines the
best application of quantitative and other tools to critical
problems in the paleontological sciences including such topics as
analysis of the Cambrian Explosion and the question regarding the
presence of life on Mars. The book considers how we think about
certain types questions and shows how we can refine our approach to
analysis right from the beginning of any particular research
effort. The analytical tools presented here will have wide
application to other fields of knowledge; as such the book
represents a major contribution to our deployment of modern
scientific method.
Authored by the internationally renowned Jose M. Carcione, Wave
Fields in Real Media: Wave Propagation in Anisotropic, Anelastic,
Porous and Electromagnetic Media examines the differences between
an ideal and a real description of wave propagation, starting with
the introduction of relevant stress-strain relations. The
combination of this relation and the equations of momentum
conservation lead to the equation of motion. The differential
formulation is written in terms of memory variables, and Biot's
theory is used to describe wave propagation in porous media. For
each rheology, a plane-wave analysis is performed in order to
understand the physics of wave propagation. This book contains a
review of the main direct numerical methods for solving the
equation of motion in the time and space domains. The emphasis is
on geophysical applications for seismic exploration, but
researchers in the fields of earthquake seismology, rock acoustics,
and material science - including many branches of acoustics of
fluids and solids - may also find this text useful. New to this
edition: This new edition presents the fundamentals of wave
propagation in Anisotropic, Anelastic, Porous Media while also
incorporating the latest research from the past 7 years, including
that of the author. The author presents all the equations and
concepts necessary to understand the physics of wave propagation.
These equations form the basis for modeling and inversion of
seismic and electromagnetic data. Additionally, demonstrations are
given, so the book can be used to teach post-graduate courses.
Addition of new and revised content is approximately 30%.
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.
