The Frozen Earth by Peter J. Williams,Michael W. Smith Pdf

This book describes the effects of cold climates on the surface of the earth. Using scientific principles, the authors describe the evolution of ground thermal conditions and the origin of natural features such as frost heave, solifluction, slope instabilities, patterned ground, pingos and ice wedges. The thermodynamic conditions accompanying the freezing of water in porous materials are examined and their fundamental role in the ice segregation and frost heave processes is demonstrated in a clear and simple manner. This book concentrates on the analysis of the causes and effects of frozen ground phenomena, rather than on the description of the natural features characteristic of freezing or thawing ground. Its scientific approach provides a basis for geotechnical analyses such as those essential to resource development.

Frozen Earth by Doug Macdougall Pdf

In this engrossing and accessible book, Doug Macdougall explores the causes and effects of ice ages that have gripped our planet throughout its history, from the earliest known glaciation—nearly three billion years ago—to the present. Following the development of scientific ideas about these dramatic events, Macdougall traces the lives of many of the brilliant and intriguing characters who have contributed to the evolving understanding of how ice ages come about. As it explains how the great Pleistocene Ice Age has shaped the earth's landscape and influenced the course of human evolution, Frozen Earth also provides a fascinating look at how science is done, how the excitement of discovery drives scientists to explore and investigate, and how timing and chance play a part in the acceptance of new scientific ideas. Macdougall describes the awesome power of cataclysmic floods that marked the melting of the glaciers of the Pleistocene Ice Age. He probes the chilling evidence for "Snowball Earth," an episode far back in the earth's past that may have seen our planet encased in ice from pole to pole. He discusses the accumulating evidence from deep-sea sediment cores, as well as ice cores from Greenland and the Antarctic, that suggests fast-changing ice age climates may have directly impacted the evolution of our species and the course of human migration and civilization. Frozen Earth also chronicles how the concept of the ice age has gripped the imagination of scientists for almost two centuries. It offers an absorbing consideration of how current studies of Pleistocene climate may help us understand earth's future climate changes, including the question of when the next glacial interval will occur.

An Introduction to Frozen Ground Engineering by Orlando B. Andersland,B. Ladanyi Pdf

Frozen Ground Engineering first introduces the reader to the frozen environment and the behavior of frozen soil as an engineering material. In subsequent chapters this information is used in the analysis and design of ground support systems, foundations, and embankments. These and other topics make this book suitable for use by civil engineering students in a one-semester course on frozen ground engineering at the senior or first-year-graduate level. Students are assumed to have a working knowledge of undergraduate mechanics (statics and mechanics of materials) and geotechnical engineering (usual two-course sequence). A knowledge of basic geology would be helpful but is not essential. This book will also be useful to advanced students in other disciplines and to engineers who desire an introduction to frozen ground engineering or references to selected technical publications in the field. BACKGROUND Frozen ground engineering has developed rapidly in the past several decades under the pressure of necessity. As practical problems involving frozen soils broadened in scope, the inadequacy of earlier methods for coping became increasingly apparent. The application of ground freezing to geotechnical projects throughout the world continues to grow as significant advances have been made in ground freezing technology. Freezing is a useful and versatile technique for temporary earth support, groundwater control in difficult soil or rock strata, and the formation of subsurface containment barriers suitable for use in groundwater remediation projects.

Rogue Star by Jasper Scott Pdf

A DEAD STAR IS HEADED FOR EARTH...THE SHIFT IN EARTH'S ORBIT WILL UNLEASH A NEW ICE AGE...AND THIS SUMMER WILL BE OUR LAST.THE NEWS BREAKSLogan Willis's life is falling apart: he lost his job and found out that his wife is cheating on him all in the same day. Thinking that his world has ended, Logan checks into a hotel and turns on the TV to see that he's not far wrong-radio telescopes have detected mysterious signals coming from inside our solar system, and the source is moving toward us at over 500 miles per second. The media concludes that these signals must be of an alien origin. Still reeling from the news, Logan gets a phone call from his brother-in-law. Richard is talking crazy about the end of the world again, but this time he doesn't sound so crazy.A DEADLY CONSPIRACY UNRAVELSMeanwhile, Richard, who is an astronomer working with the James Webb Space Telescope, is at the White House briefing the president to announce what he and the government have known for almost a decade: aliens are not invading, a frozen ball of gas is. The so-called rogue star is predicted to make a near pass with Earth, disrupting our orbit and unleashing an ice age, the likes of which we haven't seen for millions of years.WE'RE PUTTING A COLONY ON MARSGovernment insider, Billionaire Ackron Massey, has received a steady flow of funding over the past decade for his company, Starcast, to put a colony on Mars. Over the same period he's been using his personal fortune to create a colony closer to home where he plans to ride out the coming storm along with a thousand of the smartest people on the planet. Humanity will need seeds to plant in the ashes after the chaos clears.AND WARS IGNITEWhen the true nature of the threat becomes known, the nations of Earth prepare to fight over all the warmest parts of the planet. But as war fleets set sail and armies begin marching south, a stunning discovery is made that will change a lot more than just the weather....

Geocryology by Stuart A. Harris,Anatoli Brouchkov,Cheng Guodong Pdf

This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature. Finalist of the 2019 PROSE Awards.

Thermal Design Considerations in Frozen Ground Engineering by Thomas G. Krzewinski,Rupert G. Tart Jr. Pdf

Prepared by the Technical Council on Cold Regions Engineering of ASCE. The design of engineering projects in frozen ground requires thermal design considerations in addition to standard geotechnical design. Factors that influence the thermal characteristics of a site include climatological data, microclimatic characteristics, local hydrology, soil properties, and disturbance. This monograph presents ground temperature observations, procedures for temperature monitoring, analytical methods for ground thermal regime calculations, and ground thermal properties. Active and passive techniques for ground temperature control and ground thawing methods are also presented, followed by case histories of ground temperature effects.

Frozen Planet II by Leisa Stewart-Sharpe Pdf

Our planet is powered by the oceans, entangled in plants, and home to animals of every colour, shape and size. But in its last true wilderness, our planet is white . . . welcome to our frozen planet. Each year, a quarter of our planet is frozen solid, so let's journey to these ice kingdoms: Dive under the ice ceiling and learn to swim with the seal pups, take to the skies with frozen flamingos, and settle in for a snooze with a windy walrus. Watch orcas sneak up on bowhead whales while they're relaxing in the spa, meet a Greenland shark that is easily 250 years old, and witness the polar bears who are finding their food closer and closer to humans. Hold your breath in the frozen forest where wolves play hide-and-seek with bison, and meet the lemmings that outwit an arctic fox by building their home right under her feet, buried deep beneath the snow. Wrap up warm, and discover spine-tingling true stories from our incredible planet, in this ground-breaking new BBC Earth series narrated by Sir David Attenborough.
