Seismic and sonic instrumentation for `ocean engineering´

Since the successful launching of Sputnik in 1957, much of our attention has been directed skyward in viewing the wonders of our rapidly evolving technology for the conquest of outer space. More recently, our gaze has been diverted in the opposite direction in appreciation of the remarkable progress that is being made in the conquest of another frontier¿ inner space¿the deep and heretofore impenetrable reaches below the oceanic vastness that constitutes 77 percent of the earth´s surface area. In a series of three articles, the diverse areas of ocean engineering¿ the application of the oceanographic sciences¿ will be discussed in the significance of their broad implications for the future benefit of mankind.
