Crustal Permeability


Book Description

Permeability is the primary control on fluid flow in the Earth’s crust and is key to a surprisingly wide range of geological processes, because it controls the advection of heat and solutes and the generation of anomalous pore pressures. The practical importance of permeability – and the potential for large, dynamic changes in permeability – is highlighted by ongoing issues associated with hydraulic fracturing for hydrocarbon production (“fracking”), enhanced geothermal systems, and geologic carbon sequestration. Although there are thousands of research papers on crustal permeability, this is the first book-length treatment. This book bridges the historical dichotomy between the hydrogeologic perspective of permeability as a static material property and the perspective of other Earth scientists who have long recognized permeability as a dynamic parameter that changes in response to tectonism, fluid production, and geochemical reactions.




Information Fusion and Geographic Information Systems


Book Description

The Workshop Proceedings reflect problems of advanced geo-information science as far as they are specifically concerned with the maritime environment at large. The Proceedings incorporate papers presented by leading scientists researching in the considered professional area and by practitioners engaged in GIS and GIS applications development. They pay close attention to the problems of scientific and technological innovations and the ensuing opportunities to make seas safer and cleaner. Furthermore, they periodically measure the ground covered and new challenges with respect to economic and shipping trends as related to Artificial Intelligence; GIS ontologies; GIS data integration and modelling; Underwater acoustics; GIS data fusion; GIS and corporate information systems; GIS and real-time monitoring systems; GIS algorithms and computational issues; Novel and emerging marine GIS research areas; Monitoring of maritime terrorist threat; Maritime and environmental GIS; Navigation-based and maritime transportation GIS; Human factors in maritime GIS; Coastal and environmental GIS.

Countering Cyber Sabotage


Book Description

Countering Cyber Sabotage: Introducing Consequence-Driven, Cyber-Informed Engineering (CCE) introduces a new methodology to help critical infrastructure owners, operators and their security practitioners make demonstrable improvements in securing their most important functions and processes. Current best practice approaches to cyber defense struggle to stop targeted attackers from creating potentially catastrophic results. From a national security perspective, it is not just the damage to the military, the economy, or essential critical infrastructure companies that is a concern. It is the cumulative, downstream effects from potential regional blackouts, military mission kills, transportation stoppages, water delivery or treatment issues, and so on. CCE is a validation that engineering first principles can be applied to the most important cybersecurity challenges and in so doing, protect organizations in ways current approaches do not. The most pressing threat is cyber-enabled sabotage, and CCE begins with the assumption that well-resourced, adaptive adversaries are already in and have been for some time, undetected and perhaps undetectable. Chapter 1 recaps the current and near-future states of digital technologies in critical infrastructure and the implications of our near-total dependence on them. Chapters 2 and 3 describe the origins of the methodology and set the stage for the more in-depth examination that follows. Chapter 4 describes how to prepare for an engagement, and chapters 5-8 address each of the four phases. The CCE phase chapters take the reader on a more granular walkthrough of the methodology with examples from the field, phase objectives, and the steps to take in each phase. Concluding chapter 9 covers training options and looks towards a future where these concepts are scaled more broadly.




The Art of Managing Longleaf


Book Description

Greenwood Plantation in the Red Hills region of southwest Georgia includes a rare one-thousand-acre stand of old-growth longleaf pine woodlands, a remnant of an ecosystem that once covered close to ninety million acres across the Southeast. The Art of Managing Longleaf documents the sometimes controversial management system that not only has protected Greenwood's “Big Woods” but also has been practiced on a substantial acreage of the remnant longleaf pine woodlands in the Red Hills and other parts of the Coastal Plain. Often described as an art informed by science, the Stoddard-Neel Approach combines frequent prescribed burning, highly selective logging, a commitment to a particular woodland aesthetic, intimate knowledge of the ecosystem and its processes, and other strategies to manage the longleaf pine ecosystem in a sustainable way. The namesakes of this method are Herbert Stoddard (who developed it) and his colleague and successor, Leon Neel (who has refined it). In addition to presenting a detailed, illustrated outline of the Stoddard-Neel Approach, the book—based on an extensive oral history project undertaken by Paul S. Sutter and Albert G. Way, with Neel as its major subject—discusses Neel's deep familial and cultural roots in the Red Hills; his years of work with Stoddard; and the formation and early years of the Tall Timbers Research Station, which Stoddard and Neel helped found in the pinelands near Tallahassee, Florida, in 1958. In their introduction, environmental historians Sutter and Way provide an overview of the longleaf ecosystem's natural and human history, and in his afterword, forest ecologist Jerry F. Franklin affirms the value of the Stoddard-Neel Approach.




Longleaf, Far as the Eye Can See


Book Description

Longleaf forests once covered 92 million acres from Texas to Maryland to Florida. These grand old-growth pines were the "alpha tree" of the largest forest ecosystem in North America and have come to define the southern forest. But logging, suppression of fire, destruction by landowners, and a complex web of other factors reduced those forests so that longleaf is now found only on 3 million acres. Fortunately, the stately tree is enjoying a resurgence of interest, and longleaf forests are once again spreading across the South. Blending a compelling narrative by writers Bill Finch, Rhett Johnson, and John C. Hall with Beth Maynor Young's breathtaking photography, Longleaf, Far as the Eye Can See invites readers to experience the astounding beauty and significance of the majestic longleaf ecosystem. The authors explore the interactions of longleaf with other species, the development of longleaf forests prior to human contact, and the influence of the longleaf on southern culture, as well as ongoing efforts to restore these forests. Part natural history, part conservation advocacy, and part cultural exploration, this book highlights the special nature of longleaf forests and proposes ways to conserve and expand them.




Looking for Longleaf


Book Description

Covering 92 million acres from Virginia to Texas, the longleaf pine ecosystem was, in its prime, one of the most extensive and biologically diverse ecosystems in North America. Today these magnificent forests have declined to a fraction of their original extent, threatening such species as the gopher tortoise, the red-cockaded woodpecker, and the Venus fly-trap. Lawrence S. Earley explores the history of these forests and the astonishing biodiversity within them, drawing on extensive research and telling the story through first-person travel accounts and interviews with foresters, ecologists, biologists, botanists, and landowners. The compelling story Earley tells here offers hope that with continued human commitment, the longleaf pine might not just survive, but once again thrive.
