Methodological review demonstrates instrument sensitivity requirements in deep Earth exploration, highlighting the critical need for stability to capture minute geophysical fluctuations.
A great variety of instruments are being used to measure geophysical parameters. Many of these parameters exhibit extremely small variations about a large average value. Since it is often the small variations that are of interest to the geophysicist, these instruments usually must be extremely sensitive and stable.
