Available in PDF, EPUB and Kindle. Book excerpt: Research on the statistics of gravity anomalies is presented in the first part. New and independent methods for computing the statistical functions Es and Gs are described. Es, the error of representation, can be obtained using a map with iso-anomaly curves. Gs, the root mean square anomaly, may be computed if the covariance function, Cd, is given empirically. The formulas are illustrated by some numerical examples. The second part treats the continuation of the gravity anomaly field to different elevations. An earlier integral formula, expressing them in terms of gravity anomalies at ground level, can be simplified and adapted for electronic computing. For manual computation the statistical method described above is used to find a template which gives satisfactory accuracy with the least amount of labor. The derived methods for the manual and high speed computation for the extension of the gravity field in unsurveyed areas and its continuation to high elevations have great theoretical and practical significance.

Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the density of the subsurface of a planet is crucial in determining its interior structure, and one can estimate the average bulk crustal density directly using the admittance between topography and gravity, which has been successfully used for the Moon and is being extended to Mars. The interpretation of gravity data is commonly done by computation of a gravity anomaly (GA) by correcting the raw data for a number of factors that impact the gravity field. Depending on the target science, different types of GA can be computed, the interpretation of which have been widely employed in geophysics to explore the interior of the Earth and other planets, through applications in airborne gravity, near-surface geophysics, regional geophysics, and planetary geophysics. Yet how to extract a great variety of information from GAs for applications in geophysics entails further investigation. Over the decades, remarkable progress has been made to extract information from GAs identified from data. For instance, a series of 3D inversion algorithms facilitates the extraction of the subsurface density distribution. With the improved processing based on dense gravity observations that yield high precision and high resolution GAs, more detailed geological information can be unveiled. When using the admittance between topography and gravity to estimate the crustal density, it is essential to identify what kinds of GAs to be used, such as Bouguer gravity or free-air gravity. Also, what appropriate approaches to scrutinize the applications of GAs in various case studies (e.g., calculating the geoid and estimating the elastic thickness) need to be decoded.
Download or read book Gravity Interpretation written by Wolfgang Jacoby and published by Springer Science & Business Media. This book was released on 2009-02-01 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gravity interpretation involves inversion of data into models, but it is more. Gravity interpretation is used in a “holistic” sense going beyond “inversion”. Inversion is like optimization within certain a priori assumptions, i.e., all anticipated models lie in a limited domain of the a priori errors. No source should exist outside the anticipated model volume, but that is never literally true. Interpretation goes beyond by taking “outside” possibilities into account in the widest sense. Any neglected possibility carries the danger of seriously affecting the interpretation. Gravity interpretation pertains to wider questions such as the shape of the Earth, the nature of the continental and oceanic crust, isostasy, forces and stresses, geol- ical structure, nding useful resources, climate change, etc. Interpretation is often used synonymously with modelling and inversion of observations toward models. Interpretation places the inversion results into the wider geological or economic context and into the framework of science and humanity. Models play a central role in science. They are images of phenomena of the physical world, for example, scale images or metaphors, enabling the human mind to describe observations and re- tionships by abstract mathematical means. Models served orientation and survival in a complex, partly invisible physical and social environment.

Download or read book Mean Gravity Anomaly Prediction Techniques with a Comparative Analysis of the Accuracy and Economy of Selected Methods written by Luman E. Wilcox and published by . This book was released on 1982 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mean gravity anomalies are predicted to provide the average value of gravity within 1 deg x 1 deg surface areas or surface areas of other sizes. Prediction methods include conventional, statistical, deterministic, and geophysical. The statistical methods appear to give the best results when adequate computer resources are available. The deterministic methods give good results with minimum time and computer requirements. The geophysical methods give usable predictions when little or no measured data is available. The most accurate conventional method is graphical interpolation, but this method is too time-consuming to be recommended for general use.
