Comparing the Nano-Resolution Depth Sensor to the Co-located Ocean Bottom Seismometer at MARS

Data from earthquake measurements using a Nano-Resolution Pressure Sensor and a co-located Ocean Bottom Seismometer have been compared and analyzed. It is shown that the Nano-Resolution Pressure Sensor can serve as a vertical OBS. Moreover, using the pressure sensor in conjunction with a seismometer helps to separate the ocean and seismic signals.
