Gravity Measurements in Alaska
Outlines development and present status of observation program carried out by the authors since 1950. Field procedure consisted of establishment of base stations and a calibration standard for all gravity meters used, and setting up subsidiary base stations. Observations were made at 5- to 10-mile i...
