Free-air gravity anomaly maps of the Pacific Ocean basin and its margins:

These maps are based only on shipboard, submarine pendulum and land gravity measurements and are contoured at 25 mGal interval with selected annotated values in mGal shown between contours. The maps were originally published (with an accompany text) between 1976 and 1983 by the Geological Society of America as part of its Special Map and Chart Series.
