“…High tower experiments [4] have put limits on the variation of G with distance, but provide no direct estimate of the gravitational constant. In mines [5], in boreholes [6], and in the ocean [7] the value of G could be determined with the density of the traversed material. These experiments mainly suer from the insufficient knowledge of local topography and density anomalies in the Earth's crust.…”

The Newtonian gravitational constant has been determined at an effective interaction distance of 112 m. A high-precision balance was used to compare the weights of two 1-kg stainless steel masses located above and below the variable water level of a pumped-storage lake. Rater-level changes up to 43 m produced a maximum weight difFerence of 1290 pg, which could be measured with a resolution of ( 1 yg. The data yield a value for the gravitational constant G of (6.6700 6 0.0054) x 10 m kg s (lo), in agreement with laboratory determinations. New limits for the strength of possible new intermediate-range forces are placed.

“…The most recent measurement of G, the gravitational constant, on a macroscopic scale of 500 m, done by Zumberge et al (1991), gave a value of G D .6:677˙0:013/ 10 11 m 3 s 2 kg 1 which was consistent, within the experimental uncertainty, with the best laboratory value of 6:6726 10…”

“…Thus G(R,) = G(RM). A measurement of G at a length scale of order 5 km was made by measuring g as a function of depth in the ocean (Zumberge et al 1991). They found agreement with the laboratory measurements of G (Luther & Towler 1982) within about 0.2 per cent, so G( 10 cm) = G(5 km) to this accuracy.…”

S U M M A R YData from three superconducting gravimeters at four different locations are analysed for agreement with theoretical computations of gravity tides and of the influence of ocean tides on gravity. The absolute value of the measured tide is determined by an independent absolute calibration of the gravimeters. The method differs from previous tests of tide theories in that it compares the entire predicted time series rather than specific harmonic constituents. In this way it is possible to test the solid earth and ocean tide effects independently. We find that the ratios of observed to predicted solid earth tides at different locations are the same within an uncertainty of about kO.2 per cent. However, the magnitude of the tides deduced by the absolute calibration of the gravimeters is 0.6 per cent larger than the theoretical solid earth tide. We point out that an accurate determination of the solid earth tide in this way provides a direct comparison between the gravitational constant, G, at laboratory scales and at the distance to the moon.
