Book Dynamics of Earth s Deep Interior and Earth Rotation

Download or read book Dynamics of Earth s Deep Interior and Earth Rotation written by J. L. Le Mouël and published by American Geophysical Union. This book was released on 1993-01-11 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 72. The study of the Earth's deep interior is the object of a spectacular development due both to new techniques of observation (including very long baseline interferometry and superconducting gravimeters) and to progress in theory spurred by new computing capability. Stimulated by the international SEDI group, founded in 1986, geophysicists from different disciplines—Earth dynamicists, seismologists, geomagneticians, mineral physicists—began to cooperate and integmte more fully one another's work. SEDI meetings favor and promote those close contacts and cooperation. Great efforts will still be needed before all the disciplinary divisions dissolve—if they ever do—but things are clearly improving, as shown by this AGU monograph. We think indeed that this volume is a good, although incomplete, illustration of the situation as described above and that it is a benchmark in the exciting story of the progress in knowledge of the deep interior of our planet.

Book Probing Earth   s Deep Interior using Space Observations Synergistically

Download or read book Probing Earth s Deep Interior using Space Observations Synergistically written by Veronique Dehant and published by Springer. This book was released on 2023-09-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the recent decades, space missions (e.g., CHAMP, GOCE, GRACE and Swarm) have been developed by space agencies in Europe and the USA to measure the Earth’s gravity and magnetic fields and their spatio-temporal variations. These successful missions have already provided a wealth of groundbreaking results about the permanent and time-variable gravity and magnetic fields of the Earth. However, more can be learned about the Earth’s structure by combining data of the gravity and magnetic fields, together with Earth’s rotation data routinely measured using space geodesy techniques, as well as with the most up-to-date modelling of the Earth's internal structure. Use in synergy of these global observables and model data represents a unique way to further investigate the physics of the deep Earth's interior. In addition to the well-known correlation between Earth’s rotation and magnetic field observed at interannual and decadal time scales, recent studies have reported unexpected correlation between spatio-temporal changes of the gravity field and magnetic field, also at interannual time scale. These changes may result from processes occurring in the liquid core and at the core-mantle boundary. This book gathers a series of chapters that provide state-of-the art overviews on the gravity field, magnetic field and Earth’s rotation observations, and on their interpretation in terms of the deep Earth’s structure, as well as on core dynamics and processes at the core-mantle boundary. The chapters 'Gravity Variations and Ground Deformations Resulting from Core Dynamics', 'Rapid Variations of Earth’s Core Magnetic Field', 'A Dynamical Prospective on Interannual Geomagnetic Field Changes', 'Core Eigenmodes and their Impact on the Earth’s Rotation', 'Earth’s Rotation: Observations and Relation to Deep Interior', 'Interiors of Earth-Like Planets and Satellites of the Solar System', 'Correction to: Interiors of Earth-like planets and satellites of the Solar System', 'Fluid Dynamics Experiments for Planetary Interiors', 'Structure, Materials and Processes in the Earth’s Core and Mantle', 'Correction to: Structure, Materials and Processes in the Earth’s Core and Mantle' and 'Applications and Challenges of GRACE and GRACE Follow-On Satellite Gravimetry' are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

This book was released on 2019-06-18 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.

Book Global Dynamics of the Earth

Download or read book Global Dynamics of the Earth written by R. Sabadini and published by Springer. This book was released on 2014-11-14 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Global Dynamics of the Earth  Applications of Viscoelastic Relaxation Theory to Solid Earth and Planetary Geophysics

Download or read book Global Dynamics of the Earth Applications of Viscoelastic Relaxation Theory to Solid Earth and Planetary Geophysics written by Roberto Sabadini and published by Springer. This book was released on 2016-05-27 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Treatise on Geophysics  Volume 7

Download or read book Treatise on Geophysics Volume 7 written by David Bercovici and published by Elsevier. This book was released on 2010-05-17 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Geophysics: Mantle Dynamics, Volume 7 aims to provide both a classical and state-of-the-art introduction to the methods and science of mantle dynamics, as well as survey leading order problems (both solved and unsolved) and current understanding of how the mantle works. It is organized around two themes: (1) how is mantle convection studied; and (2) what do we understand about mantle dynamics to date. The first four chapters are thus concerned with pedagogical reviews of the physics of mantle convection; laboratory studies of the fluid dynamics of convection relevant to the mantle; theoretical analysis of mantle dynamics; and numerical analysis and methods of mantle convection. The subsequent chapters concentrate on leading issues of mantle convection itself, which include the energy budget of the mantle; the upper mantle and lithosphere in and near the spreading center (mid-ocean ridge) environment; the dynamics of subducting slabs; hot spots, melting anomalies, and mantle plumes; and finally, geochemical mantle dynamics and mixing. - Self-contained volume starts with an overview of the subject then explores each topic in detail - Extensive reference lists and cross references with other volumes to facilitate further research - Full-color figures and tables support the text and aid in understanding - Content suited for both the expert and non-expert
