Abstract
A method of reducing surface-scattered noise includes receiving seismic data associated with a marine region, where the marine region includes an ocean bottom, a first zone including water above the ocean bottom, and a second zone including earth subsurface layers below the ocean bottom, and the received seismic data includes signals reflected from the earth subsurface layers and surface-scattered noise reflected from the ocean bottom and an ocean surface; determining a water velocity for the first zone; determining bathymetric values of the ocean bottom; based on the determined water velocity and the bathymetric values, determining a velocity model for the marine region; based on the determined velocity model and wavelet functions of seismic source signals, calculating the surface-scattered noise by solving a wave equation; and determining the signals reflected from the earth subsurface layers by subtracting the calculated surface-scattered noise from the received seismic data.
