Abstract This paper describes an application of high-resolution continuous seismic reflection profiling in which a recent development in seismic source technology, a miniature high-power, high-frequency electrodynamic (boomer type) transducer and a synchronous dual channel signal processor, were operated together to minimise low-frequency induced bubble oscillation associated with wake entrapped (and other) air bubbles. By taking advantage of the natural low pass filter effect of the sub-bottom, and the limitations of the dynamic range of simple single-channel graphic recorders, a split dual channel record was produced, one with shallow real high-resolution penetration and a second with conventional system noise-level limited penetration.
