Low Frequency Acoustic pressure waves (HYDAPLF)

Low Frequency Acoustic Pressure Waves are time-series acoustic signals sensed by a low frequency hydrophone. These acoustic measurements are made in tandem with a seismic time series. The seismic time series contains both seafloor and waterborne seismic signals, as the acoustic measurements isolate the waterborne component leaving the pure seafloor seismic signal.
