Book Description
As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

Book Description
Senior managers and Heads of Geological Survey Organizations (GSOs) from around the world have contributed a collection of papers to provide a benchmark on how GSOs are responding to national and international needs in a rapidly changing world. GSOs continue to provide key scientific information about Earth systems, natural hazards and climate change. As countries adopt sustainable development principles and the public increasingly turns to social media to find information about resource and environmental issues, the generation and communication of Earth science knowledge become increasingly important. This volume provides a snapshot of how GSOs are adapting their activities to this changing world. The different national perspectives presented converge around several common themes related to resources, environment and big data. Climate change and the UN’s Sustainable Development Goals provide an increased incentive for GSOs of the world to work in harmony, to generate knowledge of Earth systems and to provide solutions for sustainable management of the planet.

Book Description
FINALIST for the 2021 Oregon Book Award. Rooted in the Pacific Northwest, the essays in Ruby McConnell's Ground Truth: A Geological Survey of a Life cover the vast terrain of this region &– from volcanoes to city parks, the eroding shorelines along the Oregon coast, badlands, lush forests, and city parks. Combining her background as a registered geologist, McConnell's essays also weave in personal landscapes composed of grief, loss, and optimism for the future of our environment. "The Pacific Northwest that you see today is the result of forty years of radical changes in the culture and economics of what was once a resource-extraction and agriculture-driven region. They are changes so fundamental in nature and scope...that, for those of us from this place, will always be marked by the cataclysmic eruptions of Mt. St. Helens on May 18, 1980." --Ruby McConnell In this collection of 17 essays, geologist Ruby McConnell opens her part natural history, part memoir-in-essays about the Pacific Northwest with the cataclysmic eruption of Mt. St. Helens in May of 1980. She was two years old. "Everything that I have stood direct witness to since, everything I know about this place, happe
