Claim:
1. A seismic survey system, comprising: an array of seismic units, each unit including a sensor for receiving seismic signals and providing an output indicative thereof, said array being configured for performing a seismic survey of a survey area; a first seismic unit of said array operative for receiving a first seismic signal corresponding to a source event of said survey and providing a first output of first seismic information corresponding to said first seismic signal via a first output mode; and a second seismic unit of said array operative for receiving a second signal corresponding to a source event of said survey and providing a second output of second seismic information corresponding to said second seismic signal via a second output mode, wherein said first and second modes differ with respect to transmission modes by which seismic information is read out from said first and second seismic units, respectively; wherein said first seismic unit is operative to read out said first output via said first output mode and said second seismic unit is operative to read out said second output via said second output mode during a common time period.
