In this paper I present a method that uses multiple ocean bottom instruments to separate variations in seismic amplitudes and travel times caused by near‐source topography and variable source amplitudes from similar variations related to the overall one‐dimensional seismic structure. The results indicate that the standard correction for topography, sediment thickness, and source size can be improved with this method, reducing uncertainties in the velocity solution.
