Abstract: In order to use near-field measurements to obtain signature of a signal penetrating seafloor in a shallow water surveyed area, the water-bottom reflections' effect is removed. The removal is performed by obtaining first a far-field initial estimate from stacked primary pulses in the near-field measurements, and then estimating water-bottom reflection portions for different depths using differences between the near-field measurements and the far-field initial estimate. The signature of the air-gun for each shot is then deblended from the near-field measurement for the shot using the one of the water-bottom reflection portions according to a water-bottom depth associated with the shot location.

A set of candidate concepts of a surface form in a sequence of surface forms in a plaintext is obtained. First probabilities for the candidate concepts are then determined, wherein a first probability indicates likelihood that the surface form represents the respective candidate concept. One of the candidate concepts is selected for the surface form based on the first probabilities and adjacency of the surface forms in the sequence.
