The successful promulgation of any regional gravity program carried out with gravimeters depends upon several factors. These can be described as (1) instrumental characteristics, (2) calibration standard, (3) method of survey, and (4) reduction procedure. It is assumed the instrument is reliable, has adequate range, and that the observer takes normal precautions to secure good data. Although much research has been devoted to the study of the effect of slight imperfections in the pitch of the reading dial screw, reading dial graduation error, effect of pressure and temperature changes on instrumental drift rate and readings, linearity of response, and calibration stability, all that has been ascertained is that each instrument constitutes an individual problem, and that no 'two instruments have the same characteristics although in gross terms they may be identical. Therefore, in order for data obtained using several gravimeters, or data obtained by several unrelated groups to be integrated it is necessary that there be some standards for either evaluating the instruments used directly or the data obtained through spot check observations with a standardized instrument.

Wavenumber–frequency spectra of inertia–gravity and mixed Rossby–gravity waves in the equatorial Pacific Ocean Farrar, J. Thomas; Durland, Theodore S. (American Meteorological Society, 2012-11)In the 1970s and 1980s, there was considerable interest in near-equatorial variability at periods of days to weeks associated with oceanic equatorial inertia–gravity waves and mixed Rossby–gravity waves. At that time, the ...
