1. A portable seismometer group recorder for use in seismic prospecting for processing seismic-trace signals from at least one seismic wave detector comprising:

  • (a) memory means in the recorder for storing a plurality of processing instructions for processing the seismic-trace signals, wherein the processing instructions include;

    (i) instructions for weighting seismic-trace signals obtained from a plurality of initiations of a seismic source with inverse power weighting exponents selected from the group including 0, 1, 2, and 4; and

    (ii) instructions for stacking weighted seismic-trace signals;

    (b) means in the recorder responsive to transmitted coded signals for selecting processing instructions from the plurality of processing instructions stored in the memory means; and

    (c) means in the recorder for processing the seismic-trace signals from at least one seismic wave detector in accordance with the selected processing instructions.
