| مستخلص: | The history of improvements in the global standardization of gravity values since the advent of high range gravimeters in 1948 is reviewed. In particular the gravity base values given in SEG special publication International Gravity Measurements (Woollard and Rose, 1963) are evaluated against the most recent set of standardized gravity base values, The International Gravity Standardization Net, 1971 (Morelli et al, 1974). Adjunct IGSN 71 values prepared by the U.S. Defense Mapping Agency Aerospace Center (unpublished) are also used to give a more comprehensive worldwide comparison of values. The results for 787 comparisons of Woollard and Rose (1963) values and IGSN 71 values for the same sites indicate that, in general, there is no difference in gravity standard represented. However, there is a mean absolute datum difference of 14.7 mgal (standard deviation 0.25 mgal). As this value is the same as the difference in the IGSN 71 value for the Woollard and Rose primary base value at Madison, Wisconsin, it corroborates the independent assessment that there is, in general, no difference in gravity standard. |
