EARTH: 2012 - The end of the world of just another year of living in harm's way

July 24, 2012
Alexandria, VA - December 21, 2012 - the purported last day of a 5,125-year cycle in the Mesoamerican calendar - has been added to an endless list of days when the world has been expected to end. But what are our real chances of being wiped out by a catastrophic event - the kind that has happened in the past and will inevitably occur again someday? In the August issue of EARTH, we explore four of the most probable global events that could change life on Earth forever.

Near-Earth objects (NEOs), super-eruptions, solar storms and cataclysmic earthquakes all pose serious risks to our planet on a global and regional scale. However, though these threats exist, is it possible to realistically and economically prepare for them all?

Read this story and more in the August issue of EARTH Magazine, available online at http://www.earthmagazine.org

Turn trash to treasure when scientists turn nonrecylced waste into low-carbon fuel; discover how fossilized raindrops provide clues to Earth's early atmosphere; and learn about the silver lining of potentially hazardous asteroids all in this month's issue of EARTH.

The American Geosciences Institute is a nonprofit federation of geoscientific and professional associations that represents more than 250,000 geologists, geophysicists and other earth scientists. Founded in 1948, AGI provides information services to geoscientists, serves as a voice of shared interests in the profession, plays a major role in strengthening geoscience education, and strives to increase public awareness of the vital role the geosciences play in society's use of resources, resiliency to natural hazards, and interaction with the environment.

Geoscience Laboratory Manual

Geoscience Laboratory Manual
by Tom Freeman (Author)


The fifth edition has been updates includethe replacement of all 23 air-photo stereograms with Google Earth images.  Within this manual, questions are highlighted and embedded within the text, creating a dialog format and an inquiry-based learning environment. Little or no lecture is required to get students started on the exercise du jour. Minimal introductory narrative text precedes questions. Helpful hints accompany questions that some students might find difficult.

Geoscience Handbook: AGI Data Sheets, 4th (revised) Edition
by J. Douglas Walker and Harvey A. Cohen (Author), Christopher M. Keane and Abigail Howe (Editor)


One of the best-kept secrets in geology is this handy compilation of geological information. The essential reference for geoscientists in the field, office, or lab, The Geoscience Handbook provides quick reference for the key metrics and concepts, as well as short tutorials on subjects that may not be familiar to all geoscientists. The Handbook covers diverse subjects, from geophysics to geologic map symbols to GPS usage, and everything in between! Now in full color, the Handbook uses color photos when possible to better illustrate geology in the real world. New to this printing is the new and revised 2009 Geologic Timescale published by the Geological Society of America!!!!

Petroleum Geoscience

Petroleum Geoscience
by Jon Gluyas (Author), Richard Swarbrick (Author)


Petroleum Geoscience is a comprehensive introduction to the application of geology and geophysics to the search for and production of oil and gas.
Uniquely, this book is structured to reflect the sequential and cyclical processes of exploration, appraisal, development and production. Chapters dedicated to each of these aspects are further illustrated by case histories drawn from the authors' experiences. Petroleum Geoscience has a global and 'geo-temporal' backdrop, drawing examples and case histories from around the world and from petroleum systems ranging in age from late-Pre-Cambrian to Pliocene.
In order to show how geoscience is integrated at all levels within the industry, the authors stress throughout the links between geology and geophysics on the one hand, and drilling,...

Petroleum Geoscience: From Sedimentary Environments to Rock Physics

Petroleum Geoscience: From Sedimentary Environments to Rock Physics
by Knut Bjørlykke (Author)


Petroleum geoscience comprises those geoscientific disciplines which are of greatest significance for the exploration and recovery of oil and gas. These include petroleum geology, of which sedimentary geology is the main foundation along with the contextual and modifying principles of regional, tectonic and structural geology. Additionally, biostratigraphy and micropalaeontology, organic geochemistry, and geophysical exploration and production techniques are all important tools for petroleum geoscientists in the 21st century. This comprehensive textbook present an overview of petroleum geoscience for geologists destined for the petroleum industry. It should also be useful for students interested in environmental geology, engineering geology and other aspects of sedimentary geology

Mathematical and Numerical Modeling in Porous Media: Applications in Geosciences (Multiphysics Modeling)

Mathematical and Numerical Modeling in Porous Media: Applications in Geosciences (Multiphysics Modeling)
by Martin A. Diaz Viera (Editor), Pratap Sahay (Editor), Manuel Coronado (Editor), Arturo Ortiz Tapia (Editor)


Porous media are broadly found in nature and their study is of high relevance in our present lives. In geosciences porous media research is fundamental in applications to aquifers, mineral mines, contaminant transport, soil remediation, waste storage, oil recovery and geothermal energy deposits. Despite their importance, there is as yet no complete understanding of the physical processes involved in fluid flow and transport. This fact can be attributed to the complexity of the phenomena which include multicomponent fluids, multiphasic flow and rock-fluid interactions. Since its formulation in 1856, Darcy’s law has been generalized to describe multi-phase compressible fluid flow through anisotropic and heterogeneous porous and fractured rocks. Due to the scarcity of information, a high...
