Abstract

[Introduction] This survey was undertaken as part or the program of geophysical work in the Los Angeles Basin sponsored by the Division of the Geological Sciences of the California Institute of Technology. Previous work has included a seismic survey and gravimetric studies, followed by the magnetic work conducted by Sidney Schafer in 1936.

In the survey described in this report measurements of the relative vertical intensity of the earth's magnetic field were made at more than two hundred stations in the western part of the Los Angeles Basin, in the vicinity of Inglewood and the Baldwin Hills. Askania vertical-component magnetometer number 92993 was used in the work. The locations of the stations occupied with the magnetometer are shown on the accompanying map. These stations were in general one-tenth mile apart and were located on traverse lines running in a northeast-southwesterly direction. The observed magnetic readings were corrected for the effects of temperature, diurnal variation and change in latitude and longitude as later described.
