Review of Scientific Instruments, 1957
An instrument that will simulate the anomalous gravity effects of a subsurface body, having a density differing from that of its surroundings, is described. The device makes use of the similarity between the gravity equation and Lambert's cosine θ law, and enables the geophysicist to synthesize the anomaly producing body in a time much shorter than ...

Preliminary Investigation of Gravity Anomalies
Nature, 1950BECAUSE of similarity in methods of observation and reduction, it is possible to combine the gravity data of the United States Coast and Geodetic Survey and the Department of Mines and Resources of the Dominion of Canada in large-scale gravity investigations. The combined data include gravity observations extending from lat. 24° N. to 67° N.

Doppler radio tracking of the Pioneer Venus orbiter has provided gravity measures over a significant portion of Venus. Feature resolution is approximately 300–1000 km within an area extending from 10°S to 40°N latitude and from 70°W to 130°E longitude (≈200°).

Gravity anomalies in Northwestern Canada
Bulletin géodésique, 1948Free air, Bouguer, and isostatic anomalies are listed in a table of principal facts for 23 stations established by the Dominion Observatory in the area between latitudes 55 and 70 degrees, bounded on the east by Hudson Bay and on the west by Athabaska, Slave, and Mackenzie rivers.

Comparative Study on Topography Prediction Using Gravity Anomalies and Gravity Gradient Anomalies
Direct bathymetry is a primary data source for creating high-precision seafloor topography but cannot easily achieve high-resolution global coverage. Therefore, using gravity data for seafloor topography prediction is an alternative method. Current algorithms, reliant on the measurement of ship soundings and geophysical parameters, still have room for ...Yuwei Tian, Huan Xu, Jinhai Yu
