In seismic exploration broadband refers to a wider band of frequencies being recorded than in conventional seismic exploration.

In the marine case the conventional acquisition system is said to give a usable bandwidth of typically between 8–80 Hz, whereas broadband seismic systems are claimed to give usable frequencies from as low as 2.5 Hz up to 200 Hz or more. Low frequency data provides deeper penetration useful for imaging deep targets, and provides greater stability in inversion. Broader bandwidths produce sharper detailed definition. Both low and high frequencies are required for high-resolution imaging of important shallow features such as thin beds and small sedimentary traps.

On land, marine vibrators today can produce signal frequencies down to 1.5 Hz.[1].
