Abstract

An apparatus is disclosed which may include a plurality of marine seismic sources. According to some embodiments, these marine seismic sources may include a plurality of piezoelectric components. Such an apparatus may provide a useful sound pressure level for conducting marine seismic surveying. According to some embodiments, a conduit may be coupled between the plurality of marine seismic sources and a gas reservoir external to the plurality of marine seismic sources. The conduit may in some embodiments have at least one adjustable dimension for changing a frequency of the apparatus. The apparatus may be used in a method of marine seismic surveying.
