Gravity surveys are used to measure small changes in the Earth's gravity field. These changes are due to density variations in the Earth's crust and can be used for a range of investigations such as studies of deep tectonic structures or finding caves in urban engineering studies. The physical property being measured, density variation, is the same in these investigations; it is just the survey parameters and precision required that differ. This manual serves to give a brief outline of the theory behind gravity surveying and discusses the considerations that need to be addressed when conducting gravity surveys. Gravity survey design and field techniques are discussed including both gravity and positioning equipment. Survey reduction and processing techniques are also discussed. This manual is not a definitive text on gravity surveying but rather a guide to techniques that have proved to be successful. As such, it is hoped it will be updated as techniques and instrumentation improve. Feedback or suggestions are welcome.
