Abstract: A digital seismic sensor adapted to be connected, via a two-conductor line, to an acquisition device. The digital seismic sensor includes: a digital sensor; a local sampling clock providing a sampling frequency; a receiver for receiving command data coming from the acquisition device and synchronization information providing accurate timing information to enable seismic sensor synchronization; a compensator for compensating, as a function of the synchronization information, a drift of the local sampling clock; a transmitter for transmitting seismic data towards the acquisition device; a driver for driving the receiver and the transmitter, according to a half-duplex transmission protocol over the two-conductor line and using a transmission clock extracted from the received command data; a power receiver for receiving electrical power; and a coupler for coupling the command and synchronization information receiver, the transmitter and the power receiver to the two-conductor line.

Abstract: A method for harvesting seismic data and generating seismic output files from the seismic data and corresponding source data. The method includes: positioning, in a survey area, data acquisition units associated with sensors; performing at least one seismic event using at least one seismic source; acquiring seismic data in the data acquisition units, the seismic data resulting from the at least one seismic event; deploying at least two data harvester units at fixed positions in the survey area. Each data harvester unit: harvests the seismic data; receives source data relating to the seismic event; generates a partial seismic output file from the harvested seismic data and the received source data; transmits the partial seismic output file to a central unit. The method also comprises generating, by the central unit, a final seismic output file from the partial seismic output files transmitted by the at least two data harvester units.
