Acoustic logging is a multidisciplinary technology involving basic theory, instrumentation, and data processing/interpretation methodologies. The advancement of the technology now allows for a broad range of measurements to obtain formation properties such as elastic wave velocity and attenuation, formation permeability, and seismic anisotropy that are important for petroleum reservoir exploration. With these advances, it is easier to detect and characterize formation fractures, estimate formation stress field, and locate/estimate petroleum reserves. The technology has evolved from the...

Following the breakthrough in the last decade in identifying the key parameters for time and depth imaging in anisotropic media and developing practical methodologies for estimating them from seismic data, Seismic Signatures and Analysis of Reflection Data in Anisotropic Media primarily focuses on the far reaching exploration benefits of anisotropic processing.

This volume provides the first comprehensive description of reflection seismic signatures and processing methods in anisotropic media. It identifies the key parameters for time and depth imaging in transversely...

In Chapter 2, the linear treatment of time series is provided. Particular attention is paid to Wold decomposition theorem and...

Climate for the 21st century is expected to be considerably different from the present and recent past. Industrialization growth combined with the increasing CO2 concentration in the atmosphere and massive deforestation are well above the values over the past several decades and are expected to further grow. Air temperature is rising rapidly well as does the weather variability producing frequent extreme events. Six of the ten warmest years occurred in the 1990s. Temperatures predicted for the 21st century ranges well above the present day value.

The time period of the last 100-200...

The critically acclaimed serialized review journal for nearly fifty years, Advances in Geophysics is a highly respected publication in the field of geophysics. Since 1952, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. Now with over 45 volumes, the Serial contains much material still relevant today-truly an essential publication for researchers in all fields of geophysics.

Robert Hooke's hypotheses concerning the origin of terrestrial features were of major importance to the development of geology. This book interprets Hooke's Lectures and Discourses of Earthquakes, and Subterraneous Eruptions (1667-1694). The volume consists of the original text of the Discourses transposed into modern type and paired with explanatory annotations; a brief up-to-date biography of Hooke, with emphasis on his geological contributions; and a comparison of selected passages from James Hutton, to show the transmission of ideas and Hooke's influence on later...

Fluid Physics in Geology is aimed at geology students who are interested in understanding fluid behavior and motion in the context of a wide variety of geological problems, and who wish to pursue related work in fluid physics. The book provides an introductory treatment of the physical and dynamical behaviors of fluids by focusing first on how fluids behave in a general way, then looking more specifically at how they are involved in certain geological processes. The text is written so students may concentrate on the sections that are most relevant to their own needs. Helpful problems...

Lectures on Geophysical Fluid Dynamics offers an introduction to several topics in geophysical fluid dynamics, including the theory of large-scale ocean circulation, geostrophic turbulence, and Hamiltonian fluid dynamics. Since each chapter is a self-contained introduction to its particular topic, the book will be useful to students and researchers in diverse scientific fields.

Aimed at graduate students, researchers and academics in mathematics, engineering, oceanography, meteorology, and mechanics, this text provides a detailed introduction to the physical theory of rotating fluids, a significant part of geophysical fluid dynamics. The text is divided into four parts, with the first part providing the physical background of the geophysical models to be analyzed. Part two is devoted to a self contained proof of the existence of weak (or strong) solutions to the imcompressible Navier-Stokes equations. Part three deals with the rapidly rotating Navier-Stokes...

Recon?guring Disturbance, Succession, and Forest Management: The Science of Mount St. Helens When Mount St. Helens erupted on May 18, 1980, it did more than just recon?gure a large piece of Cascadian landscape. It also led to dramatic revisions in our perspectives on disturbances, secondary succession, and forestry practices. The Mount St. Helens landscape turned out to be a far more complex place than the "moonscape" that it initially appeared to be. Granted, a large area was literally scoured and sterilized, and that vast expanse of newly formed rock, mud?ows, and avalanche debris up and...

These pages present a collection of recent papers primarily documenting the nascent science of neutrino geophysics. Most of the papers followed from talks given at 1 Neutrino Sciences 2005: Neutrino Geophysics held at the University of Hawaii in December 2005. Several papers were solicited later in an e?ort to make the collection as comprehensive as possible. Every paper was scrutinized by an external reviewer to assure the quality of scienti?c content. These reviewers are thanked for lending their scienti?c expertise through their many thoughtful comments and suggestions. All authors are...

In this lay reader's introduction to the most spectacular and devastating of all geological events, Rolf Schick describes how earthquakes and volcanoes are related, and how they are an integral part of Earth's structure. Tracing the latest findings and theories in plate tectonics, he helps readers ask and answer the basic questions: What was it during the formation of Earth that led to these phenomena? Why do they occur in certain areas and not in others? How can we, within reason, protect ourselves from their devastation? And how far have we come, and how far can we go, in predicting when...

The use of GIS, and its application for solving environmental problems, is growing rapidly. This powerful set of tools can be used to great effect in hydrological modelling, environment and habitat assessments, ecosystem studies, monitoring of wetlands and forested watersheds, urban studies, agricultural impact assessment and much more.

Geophysical measurements, such as the lateral variations in seismic wave velocities that are imaged by seismic tomography, provide the strongest constraints on the structure of the Earth's deep interior. In order to interpret such measurements in terms of mineralogical/compositional models of the Earth's interior, data on the physical and chemical properties of minerals at high pressures and temperatures are essential. Knowledge of thermodynamics, phase equilibria, crystal chemistry, crystallography, rheology, diffusion and heat transport are required to characterize the structure and...
