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.

Download or read book Magnetic Fields in the Solar System written by Hermann Lühr and published by Springer. This book was released on 2018-01-10 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses and reviews many of the still little understood questions related to the processes underlying planetary magnetic fields and their interaction with the solar wind. With focus on research carried out within the German Priority Program ”PlanetMag”, it also provides an overview of the most recent research in the field. Magnetic fields play an important role in making a planet habitable by protecting the environment from the solar wind. Without the geomagnetic field, for example, life on Earth as we know it would not be possible. And results from recent space missions to Mars and Venus strongly indicate that planetary magnetic fields play a vital role in preventing atmospheric erosion by the solar wind. However, very little is known about the underlying interaction between the solar wind and a planet’s magnetic field. The book takes a synergistic interdisciplinary approach that combines newly developed tools for data acquisition and analysis, computer simulations of planetary interiors and dynamos, models of solar wind interaction, measurement of ancient terrestrial rocks and meteorites, and laboratory investigations.
Download or read book Plasma Physics of the Local Cosmos written by National Research Council and published by National Academies Press. This book was released on 2004-06-06 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar and space physics is the study of solar system phenomena that occur in the plasma state. Examples include sunspots, the solar wind, planetary magnetospheres, radiation belts, and the aurora. While each is a distinct phenomenon, there are commonalities among them. To help define and systematize these universal aspects of the field of space physics, the National Research Council was asked by NASA's Office of Space Science to provide a scientific assessment and strategy for the study of magnetized plasmas in the solar system. This report presents that assessment. It covers a number of important research goals for solar and space physics. The report is complementary to the NRC report, The Sun to the Earthâ€"and Beyond: A Decadal Research Strategy for Solar and Space Physics, which presents priorities and strategies for future program activities.
Download or read book Earth s Magnetic Field written by Claudia Stolle and published by Springer. This book was released on 2018-09-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive view on the different sources of the geomagnetic field both in the Earth’s interior and from the field’s interaction with the terrestrial atmosphere and the solar wind. It combines expertise from various relevant areas of geomagnetic and near Earth space research with the aim to better characterise the state and dynamics of Earth’s magnetic field. Advances in the exploitation of geomagnetic observations hold a huge potential not only for an improved quantitative description of the field source but also for a better understanding of the underlying processes and physics. Key is the separation of the field sources in the observations, especially, but not solely, during times of quiet geomagnetic conditions, when the most subtle geomagnetic effects can be identified and become significant. The collected articles are based on the current constellation of ground and space observations, and on state-of-the-art empirical models and physics-based simulations. Thus, it provides an in-depth overview over recent achievements, current limitations and challenges, and future opportunities in the field of geomagnetism and space sciences.

Download or read book Core Dynamics written by Peter Olson and published by Elsevier. This book was released on 2010-05-18 with total page 7000 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treaties on Geophysics: Core Dynamics, Volume 8, provides a comprehensive review of the current state of understanding of core dynamics. The book begins by analyzing a subject of long-standing and on-going controversy: the gross energetics of the core. It then explains the important elements of dynamo theory; actual fluid motions in the core; the basic physical principles involved in thermochemical convection in the core and the basic equations governing the convection; and turbulence and the small-scale dynamics of the core. This is followed by discussions of the state of knowledge on rotation-induced core flows; the use of first-principles numerical models of self-sustaining fluid dynamos; and the behavior of polarity reversals in numerical dynamo models. The remaining chapters cover the various roles the inner core plays in core dynamics and the geodynamo; experiments that have shaped knowledge about the flows in the core that produce the geodynamo and govern its evolution; and ways the mantle can affect core dynamics, and corresponding ways the core can affect the mantle. Self-contained volume starts with an overview of the subject then explores each topic with in depth 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
