Abstract
A system for seismic data acquisition has been invented having, in certain aspects, one or multiple distributed data acquisition subsystems that are independent of energy source controller and/or of navigation system operation. Thus the distributed acquisition system(s) do not require a complicated and burdensome interface to the energy source controller or navigation systems. The seismic data acquisition system supplies a continuous flow of data which is buffered within a centralized data repository for short term storage until required by non-real-time processes. A seismic data acquisition method has been invented that replaces conventional closely coupled interaction between seismic acquisition systems and the energy source controller and the navigation systems by utilizing GPS time stamps on both the data as well as cycling events of the energy source controller and/or navigation systems to insure precise association of seismic data with cycling events. By continuously acquiring data with no interruption in the acquired data flow, association with energy source or navigation events may be accomplished at a latter point in time and not in the real-time operation of the acquisiti…
