Abstract:From April 5 to May 22, 1978, Microgeophysics Corporation conducted a self-potential passive-electrical survey (SP) for Atlantic Richfield Company in the area of the east and southwest rifts of Kilauea Volcano.
SP Traverses were planned and conducted by a two-member crew. The traverses were closed loops of several kilometers. All equipment and supplies were carried by hand when vehicle use was not possible. A discussion of the equipment is contained in the Instrumental Appendix.
The data-collection procedure was as follows: The leading crew member was responsible for navigating the traverse and selecting the electrode placement. Beg inning at a selected point, the trailing crew member placed his electrode and waited until the leading crew member pulled the 100 meter wire full length along the traverse. The trailing crew member held the wire end securely to indicate to the leading member that he had gone 100 meters along the traverse. The leading man then selected an electrode placement, marked the spot with bright yarn and waited for the trailing crew member to take the voltage reading, record it and signal that the data for that station was acquired. The leading man then picked up his electrode, moved along the traverse until the trailing crew member arrived at the point the leading man had just left. Using this procedure, 80 to 110 stations at 100 meter intervals were occupied per day along roads. In the Puna Forest Preserve many stations required over an hour to move the 100 meters. Therefore, the average production was about 10 to 12 stations per day.
