Abstract
A seismic data collection node has a clock for dating samples of seismic data and means for estimating a drift over time of a variable physical operating parameter of the clock. According to a predetermined non-linear law of variation of the variable physical operating parameter, the instantaneous frequency varies according to a polynomial equation of order greater than or equal to 2, such that a phase of the clock varies according to a polynomial equation of order greater than or equal to 3.
