3000m Ocean Bottom Seismograph(OBS) Geophysical Exploration Instrument
An Ocean Bottom Seismometer is designed to record the motion under oceans or lakes from man-made sources and natural sources. Our model can reach at least 3000 meters depth (max 600m) and last for more than 2 months. It consists of sensors, electronics and an acoustic release. We have many models of different band width,ranging from 0.2Hz~200Hz. And the hydrophone bandwidth ranges from 0.1Hz~30KHz.
Features:
* Highly pressure-resistant, highly corrosion-resistant shell: Max 6000m underwater pressure-resistance, strong acid, alkali corrosion and high temperature resistance.
* High precision: Intergrated with atomic clock, the timekeeping accuracy can reach amazing OCXO, 0.01 PPM@4ºC/5.28×10-10s
* Optional instrument bandwitdth: 0.2Hz-150Hz,0.5Hz-200Hz, 1Hz-200Hz,2Hz-200Hz,4.5Hz~200Hz optional, more flexible for your program
* Rather long lasting time: The power comsumption is as low as 0.25W. The maximum working time can reach 2 months, and the recyling period is 6 months.
Functions:
* Seismological research by academia and oceanographic research groups
* Hydrocarbon-related exploration
* Reservoir-related surveys
* Seismic and tsunami risk assessment
* Full-waveform inversion of seismic data
* Coastal and submarine geomorphology study
