According to a preferred aspect of the instant invention, there is provided herein a system and method for creating low frequency seismic waves. In brief, the instant invention uses a rotary propeller-type system that has been mounted in, for example, a barge or other marine vessel as a seismic source. In the preferred arrangement, the instant source will generate a seismic signal that has greater low frequency content (e.g., frequencies that are less than about 10 Hz) than has been possible heretofore. |
