“…Gravity surveys were also made during the glaciological investigations by Ohio State University. The collection of offshore gravity data around Alaska has proceeded very rapidly through the efforts of the U.S. Coast and Geodetic Survey in the Bering Sea and south of the Aleutian Arc [Peter and Elvers, 1965; Malahoff and Erickson, following paper], the University of Wisconsin in the Arctic Ocean [Ostenso, 1963[Ostenso, , 1968, Oregon State University in southeast Alaska [Dehlinger et al, 1966] and Lamont Geological Observatory [Worzel, 1965]. The number of offshore grav ity stations may soon be greater than the num ber of stations that have been obtained on land.…”

The U.S. Geological Survey began gravity surveys in Alaska ten years ago with local surveys in the Copper River and Tanana Basins. Shortly before the 1963 AGU gravity symposium [Barnes, 1965], the emphasis shifted from local surveys to the preparation of a reconnaissance gravity map of the whole state with a 10‐mgal contour interval on a scale of 1:2,500,000, which would be similar to the gravity map of the United States [Woollard and Joesting, 1964]. Data have now been obtained in approximately three‐fourths of the state, but there are large variations in both station density and geologic usefulness of the coverage. The amount of coverage is primarily influenced by the distribution of water bodies because more than three‐fourths of the stations have been obtained by riverboats, small skiffs, and floatplanes.

Since 1962 the Department of Oceanography, Oregon State University, has obtained gravity measurements in the Hawaiian and Aleutian archipelagoes, along the continental margin of North America from San Francisco Bay, California, to Cape Spencer, Alaska, and in Oregon. From 1963 through 1968 approximately 37,000 measurements were made in the regions delineated in Figure 1. These measurements provided the basis for the construction of gravity anomaly maps and studies of selected crustal and subcrustal structures. Underwater gravity meter measurements were used in 1962 to establish a near‐shore marine gravity range along the northcentral Oregon Coast near Newport, Oregon [Rinehart and Berg, 1963]. The marine gravity range provides a gravity difference of approximately 60 mgal and an accuracy of 1 mgal with a 90% level of confidence. Traverses of the Newport gravity range were made at the beginning and end of all surface ship gravity surveys of the Department of Oceanography. Estimates of the uncertainty in surface ship gravity measurements due to meter nonlinearity and sea state and navigation quality were obtained from data collected over the marine gravity range and off Oregon and Northern California [Dehlinger, 1964a; Dehlinger et al., 1966a].
