The World Magnetic Survey 1957”1969



Although the science of geomagnetism is old, many fundamental questions still remain unanswered concerning fluid motions in the earth's core, the dynamo producing and sustaining the field, interpretation of results of surveys, drawing of charts, a reference field, the secular change, and magnetic anomalies and their geologic meaning. The World Magnetic Survey (WMS) was designed to overcome the principal deficiencies in surveys and to stimulate the use of the data in studies of the fundamental problems in geomagnetism.
