1. A method of recording seismic survey data comprising the steps of:

  • a. Generating a terrestrially transmitted seismic survey event;

    b. Detecting seismic reflections of said event by a plurality of physically spaced sensors;

    c. Generating by said sensors, respective sensor signals corresponding to said seismic reflections;

    d. Transmitting said sensor signals along a plurality of first and second signal channels to respective first and second signal processing modules; and

    , e. Transmitting first and second digital signals corresponding to said seismic reflections by said first and second signal processing modules to a signal recording system, said packets being transmitted by said first and second signal processing modules at a frequency selected from a spectrum that is variable as a function of the physical properties of a digital signal carrier between said first and second signal processing modules.
