Abstract: | This is a review article on the types of gravity-measuring instruments used or tested at sea since 1903, on the various extraneous accelerations that affect sea measurements, and on results obtained in several gravity surveys using one type of meter. Free-air gravity anomaly maps are included of: (1) the Gulf of Mexico; (2) a strip west of the coast from northern California to the southern tip of Alaska; and (3) north of Hawaii. Hypothetical crustal and subcrustal sections, consistent with gravity anomalies and seismic refraction data, are included for selected regions. |
