Abstract

A seismic spread has a plurality of seismic stations positioned over a terrain of interest and a controller programmed to automate the data acquisition activity. In one embodiment, the controller forms a queue of sources that are ready to fire and initiating the firing of the sources according to a preset protocol. The sensor stations each include power management circuitry that may shift or adjust the power level of the sensor station during the data acquisition activity. During operation, the controller broadcasts data that the power management circuitry of each sensor station uses to determine the appropriate energy state for that sensor station. This determination may be made using the broadcast data alone or in conjunction with other data such as a GPS-determined position of the sensor station. Thus, in one aspect, each sensor station self-selects an energy state according to the broadcast status of the data acquisition activity. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b)
