Pollution is another major threat which has left many springs degraded or unusable, with major negative consequences for water supply, human health, environmental and cultural values. In a world with new and emerging pressures created by changing climate and ever-increasing demands to develop water and land for economic activities, the threat of pollution and degradation of springs is likely to intensify in coming years. Carefully developed management plans that are informed by: a high-quality scientific data collection programs; b extensive community consultation and participation and c effective policy and governance mechanisms will be needed to safeguard the immense value of the world's springs and protect their incalculable values. This volume will examine a series of case studies which document the major water quality threats affecting spring systems from around the globe in diverse hydrological, geological and social settings.

Fossils Inside Out brings fossils, paleoecology, and the fossil industry to life in a beautiful and easy-to-understand format suitable for young adults and older, scientists and non-scientists. This large format book is packed with information connecting the past, present, and future of life on Earth. It also reaches beyond the basics by covering historical perspectives on fossil collecting, laws that can confuse anyone, new imaging technologies, the art of fossil preparation, and how to spot a fake. Most of the imagery (90 percent) has been selected from the author's personal photographic archive, enhanced by some exceptional artwork from outside sources.

For hundreds of years, farmers and fishing communities maintained the inlet to Ellisville Marsh, a picturesque piece of coastline ten miles south of Plymouth, Massachusetts. Recognized as one of the most environmentally sensitive and ecologically valuable places in the state, the salt marsh and estuary are home to a diverse array of wildlife and a range of habitats, including low tide mudflats, a saltwater pond, intertidal zone, and fields of tall marsh grass. After agricultural and fishing activities faded away in the late twentieth century, it soon became apparent that protecting the marsh and its surroundings from development would not be enough to restore the natural equilibrium that had been lost when the inlet became blocked. Having witnessed government inaction over the years, Eric P. Cody and four other locals founded the Friends of Ellisville Marsh in 2007 to address erosion, revive tidal flows, and revitalize fisheries and wildlife in the face of climate change. Rescuing Ellisville Marsh presents the powerful case study of backyard activism, telling the story of a community that bonded with a natural place and decided to fight for it.

Earth observation is the gathering of information about planet Earth's physical, chemical and biological systems via remote sensing technologies, usually involving satellites carrying imaging devices. Earth observation is used to monitor and assess the status of, and changes in, the natural and handmade environment. In order to meet the needs of different communities--spanning private industry, academia, and the general public--NASA's Earth Observing System Data and Information System (EOSDIS) has provided various ways to discover, access, and use the data.

The North American continent has a rich record of the tectonic environments and processes that occur throughout much of Earth history. This Memoir focuses on 7 "turning points" that had specific and lasting impacts on Laurentian evolution : (1) The Neoarchean, characterized by cratonization ; (2) the Paleoproterozoic and the initial assembly of Laurentia ; (3) the Mesoproterozoic southern margin of Laurentia ; (4) the Midcontinent rift and the Grenville orogeny ; (5) the Neoproterozoic breakup of Rodinia ; (6) the mid-Paleozoic phases of the Appalachian-Caledonian orogen ; and (7) the Jurassic-Paleogene assembly of the North American Cordillera. The chapters in this Memoir provide syntheses of current understanding of the geologic evolution of Laurentia and North America, as well as new hypotheses for testing.

Earth's life story is written in its rocks. They are time machines, which can transport us over billions of years through the metamorphoses by which our planet was forged. How to Read a Rock combines a guide to deciphering these sagas of our planet's past with case studies of the rocks and landscapes that best tell those tales. Using stones as storytellers, it narrates the prehistoric forces of shifting continents; considers how manufactured rocks are transforming Earth's geology; travels with space probes to distant moons and planets; and asks what our geological past can predict of our future.

A summary by famed marine biologist Sylvia Earle of the latest insights about the present state of the ocean and a look at how its future and that of humankind are inextricably bound.

Enigma of the Skies is a joint endeavor by a scientist and a photographer to present to readers everything there is to know about auroras in an easy-to-understand matter. It explains the phenomena and describes how to predict when auroras occur using simple physics alongside a collection of beautiful photos taken both from Earth and from space.
