Computational systems and methods to be carried out by the computational systems for determining streamer-depth bias during exploration-seismology experiments are disclosed. In one aspect, the method computationally transforms recorded wavefield data from the space-time domain to a wavenumber-frequency domain and computationally deghosts the wavefield data in the wavenumber-frequency domain. The deghosted wavefield data may then computationally transformed from the wavenumber-frequency domain back to the space-time domain and stored. The computational methods include iterative minimization of a cost functional in the wavenumber-frequency domain. a, 0.4 -0.8 - --0 - 0.2 2 ,21 2.2 2.3 2.4 2.5 2.6 2.7 2,8 2.9 3 Time (Sec) 0,6 < 0 S -0.2 S -0.4 -0.6 0,8 2 2.1 2,2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 3 Time (Sec) |
