MODULAR SEISMIC NODE

A seismic node assembly includes a power source and a seismic sensor, e.g., with the power source disposed in a power source module and the seismic sensor disposed in a sensor module. A coupling can be defined by selective engagement between the power source (or power source module) and the sensor (or sensor module), with the power source electrically coupled to the seismic sensor, or a singular housing can be used. The seismic sensor is configured for acquiring seismic data when deployed to a seismic medium, and an acoustic transponder or wireless transceiver can be adapted for communicating command and clock signals during deployment and retrieval, or when the node is operationally deployed to the seismic medium.
