Differential Pressure Gauge (DPG) data, when collocated with a broadband seismometer, can be used to better distinguish between seismic signals, such as tremor and acoustic arrivals such as the tertiary phases of T waves of oceanic earthquakes, and enable optimal corrections for tilt noise on vertical seismometer channels.
