摘要： A freely-combinable multifunctional ocean-bottom seismic detection device includes a cabin body having a sealed structure and is made of a titanium alloy. A hydrophone, a first power interface, and a signal transmission sealing connector are mounted on an upper flange. A digital collector, a broadband seismometer, a global positioning system (GPS), and an electronic compass are mounted in the cabin body. The broadband seismometer is mounted on a leveling mechanism. Rechargeable lithium batteries are mounted in sealed battery compartments. A settlement coupling frame is arranged below the cabin body and is detachably connected to the cabin body. An uncoupling mechanism is mounted at a top of the cabin body. The device has a synchronous arrangement function of deployment as an independent node with data stored inside the instrument, and quick integration into a seabed foundation (or a subsurface buoy) with real-time data transmission.

摘要： The present invention provides a multi-mode dispersion energy imaging device and method for a four-component marine interface wave of an ocean bottom seismometer, belonging to the technical field of marine seismic exploration. The method includes the following steps: designing an marine interface wave artificial seismic observation system, designing a reasonable observation system according to the geological condition of the operation area to ensure the resolution of the imaging to perform the marine artificial source seismic operation carrying out the data preprocessing of the seafloor surface wave, and then carrying out the three-component seismometer Scholte wave and the acoustic guided wave dispersion energy imaging, and the one-component hydrophone acoustic guided wave dispersion energy imaging; superposing and normalizing the three-component Scholte wave dispersion energy spectrum and the one-component acoustic guided wave dispersion energy spectrum. The device is implemented based on the method above.
