REFERENCES: AUTHOR = Healy, J. H. et al. YEAR = 82 FIGNUMBER = plate 9 SOURCE = Open-file report USGS-OF-02-37 TITLE = Saudi Arabian Seismic Deep-Refraction Profile: Final Project Report Six shot points were used: five on land, with most charges placed below the water table in drill holes, and one at sea, with charges placed on the sea floor and detonated from a ship. Slightly more than 61 metric tons of explosives were used in 19 discrete firings. Seismic energy was recorded by 100 newly-developed portable seismic stations deployed in approximately 200 km-long arrays for each firing. Each station consisted of standard 2-Hz vertical component geophone coupled to a self-contained analog recording intrument equipped with a magnetic-tape cassette.
