Earth Dynamics

A rigorous overview of the solid Earth's dynamical behaviour, explaining the theory with methodology and online freeware for numerical implementation.

The Earth is a dynamic system. Internal processes, together with external gravitational forces of the Sun, Moon and planets, displace the Earth's mass, impacting on its shape, rotation and gravitational field. D. E. Smylie provides a rigorous overview of the dynamical behaviour of the solid Earth, explaining the theory and presenting methods for numerical implementation. Topics include advanced digital analysis, earthquake displacement fields, Free Core Nutations observed by the Very Long Baseline Interferometric technique, translational modes of the solid inner core observed by the superconducting gravimeters, and dynamics of the outer fluid core. This book is supported by freeware computer code, available online for students to implement the theory. Online materials also include a suite of graphics generated from the numerical analysis, combined with 100 graphic examples in the book to make this an ideal tool for researchers and graduate students in the fields of geodesy, seismology and solid Earth geophysics. The book covers broadly applicable subjects such as the analysis of unequally spaced time series by Singular Value Decomposition, as well as specific topics on Earth dynamics.

The web site hosts a variety of review materials, including maps, images, photographs, and links to external sources of geological data and images. The CD-ROM inc;udes high quality images, videos, animations, narrated "Chalk Talks", and identification modules.

New and more accurate techniques for satellite gravimetry will be available soon, with promising applications in Earth sciences. With this special issue the authors want to stimulate discussion among Earth scientists on objectives and preferences for future satellite gravimetry missions. This is an urgently needed discussion. Visions for follow-on missions have to be developed today, if they are to be realized within 10 years, given the required preparation time of such satellite missions.

How do Manhattan women remain so stunningly svelte, despite the fact that New York has more top restaurants than any other city on the planet, not to mention a bagel bar or pizzeria on nearly every corner? They eat out often, indulge in all types of cuisine and even sneak in junk food, but manage to stay trim and toned nonetheless. So what's their secret? Now you can learn to eat, lose weight and live your life the way chic New Yorkers do - and enjoy the same fabulous results. Manhattan insider Eileen Daspin reveals what real New York women - including celebrities like Sarah Jessica Parker, Anna Wintour and Tina Fey - really think about dieting and how they shop for food, cook, order in restaurants, eat, cheat, and splurge. Discover their eating secrets and waist-trimming tips, plus a detailed weight-loss program and 28-day eating plan that will fit easily into your personal lifestyle. Along with wisdom from leading nutritionists, tips from celebrity trainers and recipes by New York's most celebrated chefs, The Manhattan Diet gives you everything you need for a slim and stylish life - wherever you live.

This volume opens up new perspectives on the physics of the Earth’s interior and planetary bodies for graduate students and researchers working in the fields of geophysics, planetary sciences and geodesy. It looks at our planet in an integrated fashion, linking the physics of its interior to geophysical and geodetic techniques that record, over a broad spectrum of spatial wavelengths and time scales, the ongoing modifications in the shape and gravity field of the planet. Basic issues related to the rheological properties of the Earth and to its slow deformation are considered, in both mathematical and physical terms, within the framework of an analytical relaxation theory. Fundamentals of this theory are developed in the first two Chapters. Chapters 3-9 deal with a wide range of applications, ranging from changes in the Earth’s rotation to post-seismic deformation and from sea-level variations induced by post-glacial rebound to tidal deformation of icy moons of the Solar System. This Second Edition improves substantially our formalism implementing compressibility in viscoelastic relaxation. Chapter 5 now contains new developments in the physics of the gravitational effects of large earthquakes at subduction zones, made possible by new gravity data from space missions. The new Chapter 9 of this Second Edition on deformation and stresses of icy moons enlarges the applications of the book to Planetology, dealing with the additional complications in the theory of viscoelastic relaxation introduced by the shallow low-viscosity zones and inviscid water layers of the moons of Jupiter and Saturn.

New technologies has given us many different ways to examine the Earth. For example, we can penetrate deep into the interior of our planet and effectively X-ray its internal structure. With this technology comes an increased awareness of how our planet is continually changing and a fresh awareness of how fragile it is. Designed for the introductory Physical Geology course found in Geology, Earth Science, Geography, or Physical Science departments, Dynamic Earth: An Introduction to Physical Geology clearly presents Earth's dynamic geologic systems with their many interdependent and interconnected components. It provides comprehensive coverage of the two major energy systems of Earth: the plate tectonic system and the hydrologic cycle. The text fulfills the needs of professors by offering current content and a striking illustration package, while exposing students to the global view of Earth and teaching them to view the world as geologists.

This volume opens up new perspectives on the physics of the Earth's interior for graduate students and researchers working in the fields of geophysics and geodesy. It looks at our planet in an integrated fashion, linking the physics of its interior to the geophysical and geodetic techniques that record, over a broad spectrum of spatial wavelengths, the ongoing modifications in the shape and gravity field of the planet. Basic issues related to the rheological properties of the Earth's mantle and to its slow deformation will be understood, in both mathematical and physical terms, within the framework of an analytical normal mode relaxation theory. Fundamentals of this theory are developed in the first, tutorial part. The second part deals with a wide range of applications, ranging from changes in the Earth's rotation to post-seismic deformation and sea-level variations induced by post-glacial rebound. In the study of the physics of the Earth's interior, the book bridges the gap between seismology and geodynamics.

Those who funded the sciences of geology 150 years ago intuitively saw the Earth as a unified whole. Since that time, the sciences have specialized into physics, chemistry, biology and geology - specialization that has brought advances, but has unfortunately obscured our view of the unique role that life and death play on our planet.
