Ocean Bottom Seismometers for Naval OperationsBy Sercel Underwater Acoustics
MicrOBS is a new generation of autonomous deep 4C Ocean Bottom Seismometer.
Operated from any vessel, MicrOBS dives by itself to reach the seafloor to begin the seismic acquisition. Integrating a combination of 3-C low-distortion geophones plus a hydrophone, it will record P-S waves up to 24 days.
At any time, by sending a specific signal from the vessel, MicrObs will release its anchor to get up to the surface. Sending a radio signal and activating a flash light, it will be retrieved easily to download its data.
