The use of P-cable, very accurate navigation and GPS positioning techniques have produced an Ultra High Resolution 3D data set called SAFE-BAND with frequencies in the kilohertz range. The resolution achievable at these frequencies is on the order of a few feet vertically and horizontally. One of the most important pieces of information that can be extracted from this data set is a very finely detailed water bottom. Ghost generation and recording by submerged sources and receivers produce an interference pattern that makes data interpretation ambiguous and many times impossible. One of the challenges in deghosting data is the non-stationary nature of seismic. To address this issue and be able to derive a time varying filter we have chosen to work in the continuous wavelet domain (CWT). The CWT provides a solid mathematical framework for dealing with the non-stationary nature of seismic data, by allowing a time variant analysis for the filter design and application. The results show that this technique is effective for deghosting this very high fidelity data and is able to produce an accurate water bottom, unmasking subtle topographical features in the water bottom as well as geological features in the near surface geology.
