GRAVITY EFFECT OF EARTH TIDES*

Open publisher page 5 citations

Abstract

Abstract The gravity effect of earth tides was measured simultaneously at 26 stations, with 2 instruments at 3 of the stations. After a description of the stations, the corrections on the measurements are described. The results for the separate measurements are given and it can be stated that, within the accuracy of the measurements is very probably constant and has a value of 1.22. If this value is combined with Nishimura's value 0.66 for (1 − h + k), it can be shown that Takeuchi's earth models fit these values provided a value of 2.7 is taken for the surface density of the earth. The importance of a constant value for in gravity surveys is pointed out.
