If the boomer plate has an old elastic membrane the signal could have a low frequency drop after the first pick.
If the boomer system hasn't a perfect ground the electric noise degrades strongly the signal with a strong DC.
The vegetation presence on the bottom doesn't permit signal transmission.
If the acquisition is carried out when the sea has some rough waves, data are degradated. During processing it's possible to improve the reflections continuity.
The gas presence into the sediments doesn't permit signal transmission.
Sometimes you have ripple signal if your acquisition geometry. With a deconvolution you could improve your section.
