Abstract: A method for removing ocean bottom and/or geology related contamination. The method includes receiving first measurements corresponding to first seismic sensors mounted on a first source array; receiving second measurements corresponding to second seismic sensors mounted away from the first source array; processing the second measurements to determine a contamination model related to the ocean bottom and geology; removing the contamination model from the first measurements to obtain cleaned data; and calculating a source signature of the first source array based on the cleaned data.
