Gravity Operations in Guatemala

Abstract

This paper describes the logistics and field methods used for a gravity survey over a large concession in the northwest corner of Guatemala. Almost the entire network of lines for gravity stations was cut through heavy jungle and heliports were cut at line intersections. Logistics of the operation were heavily dependent on aircraft, using helicopters for transportation from camps to heliports, amphibian aircraft from main base to field camps and chartered DC-3 aircraft from Guatemala City to main camp. Field conditions and operations are illustrated by photographs. Statistics of operation and station production are included but no gravity data are shown.
