Description

In the spring of 1967, the Iowa Geological Survey established 42 gravity base stations at airports throughout the state to provide a more adequate and extensive gravity base station network than had existed previously. Measurements were made with LaCoste-Romberg geodetic gravity meters and were tied to the U. S. National Gravity Base Net through station Minneapolis L (I. G. C.15443L). For all but one station, the maximum network uncertainty at any station is ±0.041 milligal. One U. S. Air Force and two Woollard and Rose (1963) stations were recovererd, and the differences in observed gravity measured by the Iowa Geological Survey and reported at these stations are —0.005, 0.00, and —0.02 milligal respectively.
