Marine Seismic

Seismic refraction profiles near Kodiak, Alaska have provided data for construction of a cross‐section showing the crustal structure from the east end of Kodiak Island across the continental terrace and slope to the Aleutian Trench (Figures 1 and 2). Five reversed refraction stations and one unreversed station were available (Table 1); interpretation was aided by access to reflection profiles which cross the refraction lines (Shor, 1972).

Signal Sources

Repeatable, closely spaced signal sources from large‐capacity air guns and detection and recording of signals using highly flexible, microprocessor‐controlled, digital ocean‐bottom seismographs allow us to acquire high‐quality, large‐offset, marine seismic refraction and reflection data. The acquired data are readily adaptable to various processing techniques originally developed for seismic reflection data. There are several requirements and problems specific to the technique. For example, bubbly signals from one or two large‐capacity air guns are often preferable to bubble‐suppressed signals from tuned arrays in identifying weak arrivals at large offset distances. Recorded water‐wave signals at near ranges provide precise locations of detectors relative to shots.
