Some embodiments may also include one or more interior compartments (not shown in Figure 1 ; an example is shown in 620), or auxiliary external gas spaces (not shown), that could be sealed off from the space 145 or opened to it by servo or hydraulically controlled valves (not shown in Figure 1 ; an example is shown in 605), allowing the resonant frequency to be controlled by changing the compressibility of the gas volume defined thereby. This mechanism would provide a way to quickly jump back and forth between two or more frequencies while keeping the seismic source 100 at an approximate constant depth. Smaller changes in volume could be used to re-center the central resonant frequency as needed, allowing the compressed-gas reservoir to be tapped less frequently. The compartments/gas spaces could be organized into a "powers of 2" hierarchy so that a wide range of resonant frequencies could be specified by opening and closing various combinations of compartments.
