Book excerpt: Soil contamination . . . public lands . . . surface and groundwater pollution . . . coastal erosion . . . global warming. Have we reached the limits of this planet's ability to provide for us? If so, what can we do about it?These vital questions are addressed in The Earth Around Us, a unique collection of thirty-one essays by a diverse array of today's foremost scientist-writers. Sharing an ability to communicate science in a clear and engaging fashion, the contributors explore Earth's history and processes--especially in relation to today's environmental issues--and show how we, as members of a global community, can help maintain a livable planet. The narratives in this collection are organized into seven parts that describe: Earth's time and history and the place of people on it Views of nature and the ethics behind our conduct on Earth Resources for the twenty-first century, such as public lands, healthy forests and soils, clean ground and surface waters, and fluctuating coastlines Ill-informed local manipulations of landscapes across the United States Innovative solutions to environmental problems that arise from knowledge of the interactions between living things and the Earth's air, water, and soil Natural and human-induced global scale perturbations to the earth system Our responsibility to people and all other organisms that live on Earth. Never before has such a widely experienced group of prominent earth scientists been brought together to help readers understand how earth's environment works. Driven by the belief that earth science is, and should be, an integral part of everyday life, The Earth Around Us empowers all of us to play a more educated and active part in the search for a sustainable future for our planet and its inhabitants.

This book was released on 1995 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992, the U.S. Geological Survey cored Owens Lake to obtain a continuous paleoclimate record for the Sierra Nevada region. Owens Lake heads a chain of closed-basin lakes which are separated by a series of bedrock sills, received their water primarily from Sierra Nevadan precipitation, and overflowed during wet periods. The core records the histories of cyclic glaciation of the Sierra Nevada and water-balance of Owens Lake over the past 800 kyrs. A variety of paleoclimatic proxies have been studied, details of which may be found in Smith and Bischoff (1993). In this thesis, I report the results and interpretations of 1) grain-size and clay-mineralogical analyses performed on 3.5-m-long channel samples (%7500 years of sedimentation per sample) and point samples, 2) grain size, carbonate content, and oxygen isotopic measurements on 70-cm-long channel samples (%1500 years), and 3) a water-balance model used to infer the magnitude of runoff and evaporation changes necessary to fill the lakes in the Owens Lake system, and to determine the response time of the lake chain to climatic perturbations.

Download or read book Late Cenozoic Drainage History of the Southwestern Great Basin and Lower Colorado River Region written by Marith C. Reheis and published by Geological Society of America. This book was released on 2008-01-01 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Papers in this title were selected from presentations from an April 2005 workshop sponsored by the U.S. Geological Survey Earth Surface Dynamics Program, the U.S. Geological Survey National Cooperative Geologic Mapping Program, and the Smithsonian Institution. Papers are divided into two broad topics of the configuration, areal extent, and temporal development of the chain of interconnected lakes that emptied into Death Valley during periods of the Pleistocene, and the late Cenozoic history of drainage integration in the lower Colorado River region. Papers are occasionally illustrated in both color and black-and-white; the publication contains no index.

This book was released on 2020-06-27 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 20th century, the city of Los Angeles diverted surface water flowing into Owens Lake for water supply, transforming the large, closed-basin, saline lake into a small brine pool surrounded by dry playa. Under high winds, the exposed lakebed produced large amounts of airborne dust, resulting in the highest concentrations of airborne particulate matter with an aerodynamic diameter of 10 micrometers or less (PM10) in the United States. Since 2000, the Los Angeles Department of Water and Power, at the direction of the Great Basin Unified Air Pollution Control District, has been constructing and implementing dust control measures on the dry lakebed, with the objective of meeting the U.S. Environmental Protection Agency National Ambient Air Quality Standards for PM10 and the PM10 standards set by the state of California. Many of the dust control measures used at Owens Lake require large amounts of water, energy, and maintenance to sustain their performance. Effectiveness and Impacts of Dust Control Measures for Owens Lake evaluates the effectiveness of alternative solutions for their degree of PM10 reduction and the extent that they reduce use of water in controlling dust emissions. This report considers the associated energy and environmental and economic impacts of these proposed measures and assesses their durability and reliability.
Download or read book The Quaternary Period in the United States written by A.R. Gillespie and published by Elsevier. This book was released on 2003-12-17 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews advances in understanding of the past ca. two million years of Earth history - the Quaternary Period - in the United States. It begins with sections on ice and water - as glaciers, permafrost, oceans, rivers, lakes, and aquifers. Six chapters are devoted to the high-latitude Pleistocene ice sheets, to mountain glaciations of the western United States, and to permafrost studies. Other chapters discuss ice-age lakes, caves, sea-level fluctuations, and riverine landscapes. With a chapter on landscape evolution models, the book turns to essays on geologic processes. Two chapters discuss soils and their responses to climate, and wind-blown sediments. Two more describe volcanoes and earthquakes, and the use of Quaternary geology to understand the hazards they pose. The next part of the book is on plants and animals. Five chapters consider the Quaternary history of vegetation in the United States. Other chapters treat forcing functions and vegetation response at different spatial and temporal scales, the role of fire as a catalyst of vegetation change during rapid climate shifts, and the use of tree rings in inferring age and past hydroclimatic conditions. Three chapters address vertebrate paleontology and the extinctions of large mammals at the end of the last glaciation, beetle assemblages and the inferences they permit about past conditions, and the peopling of North America. A final chapter addresses the numerical modeling of Quaternary climates, and the role paleoclimatic studies and climatic modeling has in predicting future response of the Earth's climate system to the changes we have wrought.
Download or read book The Great Basin written by Donald Grayson and published by Univ of California Press. This book was released on 2011-04-18 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering a large swath of the American West, the Great Basin, centered in Nevada and including parts of California, Utah, and Oregon, is named for the unusual fact that none of its rivers or streams flow into the sea. This fascinating illustrated journey through deep time is the definitive environmental and human history of this beautiful and little traveled region, home to Death Valley, the Great Salt Lake, Lake Tahoe, and the Bonneville Salt Flats. Donald K. Grayson synthesizes what we now know about the past 25,000 years in the Great Basin—its climate, lakes, glaciers, plants, animals, and peoples—based on information gleaned from the region’s exquisite natural archives in such repositories as lake cores, packrat middens, tree rings, and archaeological sites. A perfect guide for students, scholars, travelers, and general readers alike, the book weaves together history, archaeology, botany, geology, biogeography, and other disciplines into one compelling panorama across a truly unique American landscape.
