Description

Understanding the Bouguer Anomaly: A Gravimetry Puzzle addresses the geophysical and geodetic applications of gravity field interpretation, taking into account the evaluation of the Bouguer anomaly. Containing several contributions that deal with persistent questions in gravity data processing and providing verified workflows, the book covers historical and practical aspects of the Bouguer anomaly.

Geophysicists and exploration geologists will gain advanced knowledge in gravimetry, physical geodesy and an understanding of the evaluation and impact of the Bouguer anomaly in gravity field measurement.

Key Features

  • Covers multiple aspects of the Bouguer anomaly, including definition, historical developments and evaluation
  • Provides verified workflows for gravity data processing, which can be applied across research and industry
  • Organized with a logical flow that begins with a definition, then continues to describe state-of-the-art and advanced approaches to terrain corrections evaluations
  • Includes an example of national gravity database organization and re-processing

Readership

Researchers and upper-level graduate students in geophysics, both academic and industrial
