×Part of the detection and monitoring of seismic events will be provided by low-frequency hydrophones (2 Hz to 20 KHz) that are well suited to detect the hydroacoustic tertiary phase of T waves of oceanic earthquakes. These sensors also detect solid-earth P waves from regional and teleseismic earthquakes. Coupled with the Ocean Bottom Seismometers, the low-frequency hydrophones will increase our ability to detect offshore earthquakes in real-time, determine their magnitude, and enable better location accuracy.
The Low Frequency Broadband Acoustic Receivers are manufactured by HTI, model 90-U. The instrument HYDLFA301 is located at Axial Base and is coupled with broadband seismometer OBSBKA301; both instruments are connected to the MJ03A J-box by a 25 m-long extension cable. The MJ03A subnet also hosts a Seafloor Pressure Sensor and a Current Meter.
