We performed an interpretive study of a field ocean bottom dataset to extract its source signature as a function of the offset and to estimate the source statics. Source signatures are obtained by capturing the direct arrival signal for the down-going wavefields. PZ summation is performed in the t-x domain with a scaling factor that is fitted from the data. Source statics are estimated by correcting the deviations from the linear moveout time. We have used two methods of performing that correction. Shifts estimations are consistent between the two approaches at small offsets. Our approaches become limited at larger offsets. As the amplitude of the signature becomes weaker with offset, obtaining the source signature and estimating the static shifts become difficult.
