Abstract
The invention is a method for suppressing noise in controlled source electromagnetic survey data based on the frequency content of the noise. The invention recognizes that some data variations across bins cannot be attributed to resistivity variations within the earth. This variation across bins constitutes a model of noise in such surveys, and the invention mitigates noises that obey this model. Noise varying rapidly in either space or time is removed by filtering temporal frequency domain data () with a low-pass filter () having a selected cutoff frequency ().
