Abstract Recent theoretical interest in the possibility of observing a non-newtonian component of gravity arises from the lead that such observations will give to unification theories1. Absolute determinations of the newtonian constant G by geophysical methods, at mass separations several orders of magnitude greater than those available in the laboratory, provide information not obtainable in any other way. Stacey2 drew attention to the fact that modern geophysical measurements were precise enough in principle to provide an important check on G and Stacey et al.3 revived the mine method first used by G. B. Airy. Subsequently Stacey analysed a set of overlapping sea-floor and sea-surface gravity survey data made available by the Exxon Oil Co., to avoid the problem of density uncertainty that beset the mine measurements, and Stacey and Tuck4 compared the results with values of G calculated from published mine and borehole data. The striking conclusion was that the values of G were all systematically high. Residual doubts, especially concerning the adequacy of density sampling and the possibility of bias by regional gravity anomalies, left the conclusion as a rather tentative one. We report here a new determination of G, which is also high, but in which the doubt about density is substantially reduced. This information makes it implausible to explain the high value of G in terms of an inadequate knowledge of density. The possible effect of regional gravity anomalies is not as securely discounted.
