  Simultaneous source seismic acquisition is an efficient method of seismic
surveying that can considerably reduce the cost of high density seismic
acquisition. The method results in overlapping records, or interference, that
must be removed prior to subsequent processing. Deblending methods typically
rely on the incoherence of the blending noise relative to the underlying
signal. There are many common situations where these assumptions break down,
for instance, when the underlying signal contains noise or erratic amplitudes,
or when shooting times are not sufficiently random. We present a robust
inversion based deblending algorithm that can overcome these challenges.
