    • A method for identifying clock timing discrepancies in a plurality of clocks that are each associated with a seismic receiver, comprises the steps of collecting from at least a pair of receivers a data set corresponding to a selected time period, cross-correlating the data sets between at least one pair of receivers so as to produce cross-correlated data for positive, zero, and negative time lags, comparing the cross-correlated data for the positive and negative time lags to measure a timing asymmetry about the zero-lag time, and, for a receiver pair for which there is a non-zero timing asymmetry, using the asymmetry to identify a timing discrepancy between the clocks associated with that receiver pair. The each data set can be filtered so as to obtain data in a selected frequency range, which may avoid an active shot frequency. The data may be collected in the absence of active seismic shots.
    • 一种用于识别每个与地震接收器相关联的多个时钟中的时钟定时差异的方法包括以下步骤:从至少一对接收器收集对应于选择的时间段的数据集,将这些数据集之间进行互相关 至少一对接收器,以产生正相关数据,零相关数据和负相关时间滞后,比较正和负时滞的交叉相关数据以测量关于零滞后时间的定时不对称性,以及 对于存在非零定时不对称的接收机对,使用不对称性来识别与该接收机对相关联的时钟之间的定时差异。 可以对每个数据集进行过滤,以便获得选定频率范围内的数据,这可以避免活动镜头频率。 这些数据可能在没有有效地震数据的情况下收集。

    • A wireless network is provided, that may comprise wireless sensor units organized in chains of wireless sensor units. Each wireless sensor unit may comprise plural sensors and at least a wireless transceiver connected to communicate by wires or wirelessly with the plural sensors. Each chain of wireless sensor units may include a terminal wireless sensor unit and intermediate wireless sensor units, each intermediate wireless sensor unit being configured to relay data along the chain of intermediate wireless sensor units towards the terminal wireless sensor unit. The terminal wireless sensor unit in each chain of wireless sensor units is adapted to communicate wirelessly with at least one backhaul unit of plural backhaul units; and the backhaul units are adapted to communicate with a central computer.
