A technique includes deploying seismic sensors to perform a seismic survey and during the deployment of the seismic sensors, testing each of the seismic sensors to determine an associated sensor transfer function. The technique includes determining an associated operator to apply to seismic data acquired by each of the seismic sensors in the seismic survey based at least in part on a frequency dependent variation between the associated sensor transfer function and a nominal response for the seismic sensor. The technique includes processing the seismic data, including applying the associated operators to the seismic data.
